BACKGROUND AND SUMMARY OF THE INVENTION 
     Field of the Invention 
     This invention relates to an integration of a hydraulic workover or “snubbing” unit and a coil tubing unit with applications including drilling, completion, well workovers and well control. Unique features of the system are: the ability to vertically stand multiple joints and pipe near the unit as opposed to laying down each joint as done in conventional operations, the combined capability of a hydraulic workover or “snubbing” unit and a coiled tubing unit in one piece of equipment, the ability to run jointed pipe in combination with coil tubing, the ability to run coil tubing in combination with jointed pipe, the use of a single hydraulic power pack to operate the jack and/or coil tubing unit, and the ability to circulate fluid while rotating and reciprocating the pipe or coiled tubing.

     The above art illustrates conventional coiled tubing operations, which like conventional jointed pipe drilling has certain deficiencies. Coiled tubing used in drilling applications can not be rotated without rotating the reel, guide arch and injector about the centerline of the well or cutting the coiled tubing and installing a connector to permit rotating the pipe then in the hole. In the former case, string rotational speed is limited to the safe rotational speed of the entire bulky assembly. In the latter situation, the coiled tubing cannot be rotated and run into or pulled out of the hole simultaneously. The absence of rotational capability requires the use of a down hole motor to drill and an orienting tool downhole to adjust toolface position during directional drilling. 
     The coiled tubing must be cut, and a connector installed, each time a piece of “jewelry” is added to the drillstring above the bottomhole assembly. Each such item must be removed before the pipe can be spooled onto the reel unless the item is specifically designed to be spoolable. Each time a connector is added to a coiled tubing string, a stress raiser is intentionally applied in the continuous pipe string, which reduces both string utility in other applications and string life in general. 
     Coiled tubing reels and support structures are heavy. The combined weight of a fully loaded spool may exceed platform crane rated capacity requiring an upgrade or a separate “bull frog” crane on some platforms to lift the reel into place for coiled tubing drilling. This is even more important as coiled tubing diameters and wall thicknesses increase for deeper drilling applications, the current trend. Lifting such heavy loads with limited cranes increases the potential for accidents including damage to equipment and injuries to personnel. 
     Jointed pipe drilling requires excessive time to trip drillpipe for changes to the string or drilling tools. A derrick or other structure is required to provide hoisting and racking capabilities for jointed-tubing tripping with attendant weight, space and maintenance requirements. 
     Jointed-pipe handling is discontinuous. Stopping and starting is required for each connection make-up or breakout required. Multiple steps are required for each such connection make-up or breakout required, each of which places operating personnel at some risk. Further, multiple equipment functions are required which relates to wear, maintenance, replacement and cost. Failure is possible at each point, any one of which can shut down operations for varying time periods. 
     The present invention achieves several advantages and improvements over conventional prior art methods and apparatus. Jointed drillpipe can be delivered in small units with weights far less than the combined weight of a loaded coiled tubing reel. Only one large reel is needed for the system instead of several when large diameter drillpipe is used for drilling deep wells. This reel is only used for tripping the drillpipe, not for shipment. The reel alternatively is in multiple pieces that are assembled on-site instead of a single large unit, or the reel may be a single collapsible unit that is expanded on-site. Either of these removes shipping complications associated with a large-diameter reel and support structure. 
     Pipe is unscrewed, straightened and shipped back in basket-sized units after its last use in the well. Similarly the reel is either dismantled or re-collapsed for shipment after the job. 
     Improvements in operation are also achieved. The pipe, once run in the hole in “singles,” can be reeled out of the hole, then back in, without breaking apart except as needed. This reduces trip time associated with jointed-pipe systems and overall cost. Drillpipe tripping is a continuous process, which reduces the potential for differential sticking while tripping. Well control issues are simplified since monitoring for kicks, filling the hole and observing fluid levels are also continuous processes. Well control measures can be enacted quickly since the spoolable drillpipe is always connected to the pump through the reel swivel. Pumping can be initiated without positioning a drillpipe body across a blow out preventer and stabbing a kelly or valve onto an open drillpipe connection. If flush joint or non upset external tubing spoolable drillpipe is used, blow out preventors can be activated even if a joint is situated in the rams. 
     With the present invention, a derrick or other support system for hoisting jointed pipe and racking it back is not required. Pipe can be unscrewed and disconnected from the reel at any connection allowing the entire string to be rotated and raised or lowered by adding or removing single joints. Thus, the system can go from continuous (reeled) to jointed at any time. The pipe can be rotated while drilling to orient downhole directional tools since the spoolable feature is generally only used for tripping, although drilling with a downhole motor is possible. During drilling, the system is a jointed-pipe operation. The entire string can be rotated at common speeds (RPMs) so it need not rely entirely on downhole motors for supplying rotation to the bit. 
     With the present invention, make-up and break-out equipment is used less frequently than with conventional jointed-pipe systems reducing maintenance, pipe-handling, replacement and personnel risk issues and, thus, costs. Personnel are not overly fatigued if multiple trips are required during a single tour, particularly at moderate to extended depths. Fewer steps with less intensive physical strength are required for tripping which will probably result in fewer injuries and work-related illnesses. Fewer crew members may be required. Automation or computer-assist systems can be incorporated with this system including real-time monitoring, level wind assist, pipe tensioning, etc. for improved efficiency with resultant cost reductions. This improved system can be used in either drilling or reworking operations on existing wells. 
     In summary, deficiencies of conventional hydraulic workover operations without a derrick are: each joint must be unscrewed from every other joint; it is not possible to continuously circulate while tripping; pipe handling is required to lay down each joint as it is pulled from the hole, which involves wear on hoisting equipment and some risk to personnel; trip time is slow in view of the above; and, a structure is required of sufficient area size and strength to hold and support the dry weight of pipe removed from the hole. 
     Deficiencies of conventional coiled tubing drilling are: lack of rotation; continual slide mode; excessive weight of tubulars and coil tubing reel; short tubular life due to the effects of low cycle fatigue; reduced capabilities in running jointed tubulars (bottom hole assemblies, and completions); non-competitive day rates; decreased penetration rates vs. hydraulic workover unit or rig due to lower weight on bit and inability to overcome friction; lower hydraulic efficiencies vs. conventional tubing due to reduced coiled tubing sizes; lesser hole cleaning capabilities; and, higher cost of pumping equipment due to lower hydraulic efficiencies. 
     It is thus desirable to combine advantages of coil tubing: continuous pumping while tripping; underbalanced drilling; faster trip time versus hydraulic workover unit or rig; smaller footprint vs. rig; less personnel required; and, reduction of personnel time required to work on a platform close to well with those of a hydraulic workover unit: the ability to rotate during all facets of job including underbalanced drilling and while tripping pipe; the ability to use segmented components better suited for existing crane capacities; running larger tubulars; running completion strings; greater hook loads; the ability to convey different diameter tubulars; a smaller footprint vs. rig or coiled tubing unit since some of the equipment is on the well; higher hydraulic efficiencies; greater hole cleaning capabilities; higher pressure capabilities for comparable tubulars; and, longer tubular useful life vs. coil tubing unit. 
     Previous attempts to combine some of hydraulic workover and coiled tubing operations also had deficiencies. Jointed pipe had to be handled by the snubbing unit while the coiled tubing injector is rigged down or “trollied” off the well centerline. Injector head lifting or snubbing force capacities were less than those of the snubbing unit in most cases which, in turn, limited the depth to which large-diameter coiled tubing could be run. With previous attempts and apparatus the coiled tubing must be cut to rig down or trolley the injector head out of the way. Excessive time is required to run or pull combinations of externally-upset end (EUE) jointed pipe and coiled tubing with prior apparatus since the injector must be rigged down or moved each time an EUE goes into or out of the well. This results in higher costs than using coiled tubing alone. 
     In summary, the present invention achieves the following improvements: EUE jointed pipe, non-upset jointed pipe and continuous pipe can be handled with a single unit, which does not require the coiled pipe to be cut to go from one pipe type to another. 
     In the event the injector head mechanically fails during a job, the coiled tubing can be run or pulled using the hydraulic jack. Similarly, if the jack fails, coiled tubing operations can continue (but jointed tubing operations can not). The injector head of the present invention does not need to be rigged down on trollied off the well centerline as a unit. Instead, the head splits apart with each half being moved back only the distance required for an EUE and collar on jointed pipe to clear the chains. The injector can be moved back into place hydraulically by the operator from the control console. This reduces time, risk to personnel and overall job cost to the customer. 
     Controls can be integrated so that a single operator can operate all system functions without switching from one piece of equipment to another. In other words, hydraulic workover operations can be replaced by coiled tubing operations by simply moving to a different set of control handles. A single power pack (hydraulic pump and engine) can be used for both operations instead of a separate one for each function, since when one system is in use, the other will not be under normal circumstances. However, both can be used simultaneously in other situations (jack assist of the coiled tubing injector to pull a heavy load, for example). 
     Well control equipment, blowout preventers (BOPs) and valves, for both equipment sets can be manifolded together using the same accumulator system so that either one or both can be functioned in the event of a well control incident. 
     The jack of the present invention is equipped with a rotary drive mechanism that can turn the entire pipe string as long as the coiled tubing is not connected to the reel. This provides the means to reduce trip time for jointed sections by allowing pipe to be “rotated out of the hole” (i.e., the top pipe can be held stationary and the bottom segment in the well can be rotated clockwise to unscrew right-hand threads and break the connection between pipe segments). 
     Jointed members can be snubbed into and out of the hole under pressure. This obviates killing the well to pull jointed tubulars such as bottomhole assemblies, a current requirement of conventional coiled tubing drilling. Thus, the well can be maintained in an underbalanced situation throughout the drilling process. Completion equipment, including jointed production tubing, packers, profile nipples, blast joints, on-off tools, gravel pack screens, landing nipples, etc. can be run with the jack following coiled tubing operations such as drilling, recompletions or workovers without killing the well. 
     The present invention may also include a “rack-back” system. If so, multiple joints can be stood back, which reduces the number of joint breaks required in conventional hydraulic workover, tubing is not laid down; rather it is stood back vertically in fingerboards in multiple joint sections reducing hoisting equipment wear and personnel risk, and trip time is reduced along with overall operation cost. 
     Dry tubing weight can be supported by the earth, the platform or the wellhead depending on which base is used for standing the tubing. This allows its use on minimal structures lacking “normal” support capabilities such as: offshore satellite (monopod) platforms; old, physically damaged or corroded platforms; and, inshore well protection structures (i.e., no platform). 
     With this added rack back system component, a supplemental structure such as a barge, lift boat, offset platform or other structure is not required to hold the horizontal tubing segments since the pipe is stood almost vertically in the wellbore vicinity. This may reduce overall job costs, and fewer opportunities exist for tubular damage due to handling which reduces equipment replacement costs and economic risk to the customer (i.e., fewer threads are exposed to damage during breakout, hoisting and laydown operations). 
     With the added components comprising a spoolable drillpipe system, jointed drillpipe can be delivered in small units with weights far less than the combined weight of a loaded coiled tubing reel. Only one large reel is needed for the system instead of several when large diameter drillpipe is used for drilling deep wells. This reel need only used for tripping the drillpipe, not for shipment. The reel is in multiple pieces that are assembled on-site instead of a single large unit. Alternatively, the reel would be a single collapsible unit that is expanded on-site. Either of these removes shipping complications associated with a large-diameter reel and support structure. Pipe is unscrewed, straightened and shipped back in basket-sized units after its last use in the well. Similarly the reel is either dismantled or recollapsed for shipment after the job.

     SUMMARY OF THE INVENTION 
     The focus of the present invention is to provide a new and improved method and apparatus for drilling, completion, well workovers and well control, combining an integrated hydraulic jacking lifting unit and a coiled tubing unit, the method and apparatus permit running jointed pipe and coil tubing in combination, and extending or racking and multiple joints of pipe near the unit. The method and apparatus includes spoolable drill pipe including a connector, multi-section reel with core, connection to reel for fluid circulation, reel drive mechanism and a pipe pulling capability. 
     The present invention comprises the following components: a hydraulic pipe hoisting system (both 2 and 4 legged embodiments are contemplated), a work basket atop the jack, a rotary table within the traveling head, a rotating swivel to allow fluid circulation during pipe rotation, pipe handling tongs onboard the work basket, pipe racking (finger) boards attached to the frame or work basket and pipe containment bases for the purpose of racking back pipe (standing single or double joints), a hydraulic workover or snubbing jack bore sufficiently large to run casing, bottom hole assembly and well tubulars (up to a least a nominal 14″ bore is suggested), a multi-function injector head, a guide arch assembly (or gooseneck), a standpipe for the purposes of fluid circulation, high pressure connections on each end of the standpipe to allow pumping, a gin pole or boom to handle and convey casing, tubing, drilling assemblies and completion tools, a multiplicity of sheaves on the top of the gin pole for handling pipe and other required services for general oilfield operations, a winching system to hoist jointed pipe and to set it down in the racking frame or lift it from the racking frame, a sub-base to allow weight distribution of the unit and pipe in a safe and efficient manner on the deck of the platform or centralized on the wellhead, at least one operator&#39;s console and a work area for controlling and operating the invention, traveling head with traveling slips and stationary slips for pipe movement in the well, hydraulic cylinders for insertion and extraction of the injector head radially relative to the centerline of the wellbore and unit, a work window to allow access to the stationary slips and for insertion and extraction of tools in the work string and, spoolable drill pipe including a connector, multi-section reel with core, connection to reel for fluid circulation, reel drive mechanism and a pipe pulling capability. 
     The invention involves track and trolleys or other suitable guides for moving the gooseneck and/or the injector head. The multi-function injector head is capable of splitting into two halves to facilitate running of large BHA&#39;s into and out of the wellbore. The injector head will move via a guide system, such as a dove tail rails, or any other guide means, radially away from the centerline of the wellbore. Hydraulic pistons translate the two halves toward each other and hold it in place. 
     As to the manner of operation and use of the present invention, the same is made apparent from the above in consideration of the following discussion and description of the details of the present invention. 
     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Snubbing is a generic term known in the art which covers the processes involved in running tubular goods (coil tubing or pipe) into or out of a wellbore while there is a surface pressure or the possibility thereof. The term snubbing refers to both stripping and snubbing. 
     Stripping is the movement of tubular goods when the pipe weight exceeds the pressure excerpted on the tubulars. In other words, the pipe must be restrained from falling into the wellbore. Snubbing is the movement of tubulars when the pressure excerpted on them is greater than their buoyed weight. This means that the tubulars must be restrained from coming out of the wellbore. 
     Hydraulic jacking or workover “snubbing” units were developed and refined primarily in the control of run away wells. Snubbing units now are more general purpose tools in the specialized oil control service industry and provide many advantages in protecting, producing formations and reducing work over and drilling costs. 
     Self contained units are trailer mounted or skid mounted for quick transport and fast rig up on wellheads on land or offshore. Modular components conformed to space limitations at a particular site and are easily transported. A workover snubbing unit and blow out preventor assembly (BOP) can be flanged directly to the top of a wellhead and all weight is generally supported through the wellhead center line, so compact units are ideal for working from non-load bearing satellite platforms, as well as other crowded platforms such as offshore platforms and drilling rig floors. 
       FIG. 2  illustrates the following functional groups and components of a conventional hydraulic workover or snubbing unit: powerpack and hydraulic pumps  1 , fuel tank  2 , tool box and work basket  3 ; control panels  4 , power tongs  5 ; counter balance winches  6 , pipe elevators  7 , ginpole  8 , and pipe racks  9 ; hydraulic jack assembly  11 , traveling  12  and stationary  13  slips, stripper  14 , and built in rotary table  15 ; and, circulating swivel  16 , kelly hose  17 , and standpipe  18 . 
     Hydraulic power supply is from the skid mounted diesel engine with hydraulic pumps mounted to the main shaft gear box. For auxiliary power functions, a separate pump may be mounted to the engine cam shaft. 
     A work basket  3  is positioned on top of the hydraulic jack assembly  11  where is mounted a control console  4  for the unit. Working from this control console  4 , the operator can direct the speed and direction of the traveling head and slip assembly, the operation of the slips and torque and direction of the rotary table  15 . The counter balance pipe winch  6  and pipe elevator  7  system, simultaneously handle one joint of pipe while laying down or picking up another. Thus, a crew can work smoothly and efficiently, reducing the damage to tubing. 
     Four hydraulic cylinders  20  of the snubbing unit are arranged around the vertical axes and tubing guide of the unit. The traveling slips  12  and a built in hydraulic rotary table  15  are contained in the traveling head which is attached to the top of the hydraulic cylinder rods  21 . Stationary slips  13  are attached to the base of the unit. 
     Operators within the work basket  3  control the hydraulic jack assembly  11 , slip bowls  12  and  13 , rotary table  15 , bleed off and equalizing valves, blow out preventor controls and counter balance controls. In some instances, operations controlled from the work basket can also function to handle power tongs  5  and large diameter tubulars. 
     When the tubing is being handled, care must be used to prevent damage. When picking up or laying tubing down, damage often occurs when connections come into contact with “V” doors, cat walks, hand rails, valves, elevators, etc. Stabbing guides  22  can be used when making up premium threaded tubulars to prevent any wobble and thus to prevent pin and box damage to the threaded tubulars. 
     With reference to the above described background of the prior art conventional snubbing apparatus as illustrated in  FIG. 2 , the following will be a detailed description of the new and improved apparatus and methods of the present invention. Referring first to  FIG. 1 , various components and sub assemblies of the present invention will be described. Where equivalent structure to that of the previously described snubbing apparatus is found, like reference numerals will be used to describe like components. 
       FIG. 1  illustrates a hydraulic jack assembly or pipe hoisting system in a four legged embodiment, that is with four hydraulic jack cylinders  20 . Alternative embodiments contemplated would use two legged configuration.  FIG. 1  does not illustrate the work basket atop the jack. The work basket  3 , atop the jack, is best illustrated in  FIGS. 3 and 4 .  FIGS. 1 ,  3 , and  4  all illustrate the rotary table  15  with the traveling head  28  and pipe handling tong  5  mounted above the traveling slip bowls  12 . The embodiment illustrated in  FIGS. 1 ,  3 , and  4  illustrates an axially aligned power tong  5  with a base plate such as as illustrated in more detail in  FIG. 8  to apply a torque sufficient to the size tubing worked. Optionally, the present invention could be used with hanging power tong  5  and a rotating tong arm such as that illustrated on the snubbing unit in FIG.  2 . 
     As shown in  FIG. 1 , the present invention includes a rotating swivel  16  to allow for pipe rotation while circulating. The power tong  5  as illustrated in  FIGS. 3 ,  4 , and  8  is mounted to a frame work above the slip bowls of the traveling slip and the hydraulic powered rotary so that although the slip bowls  12  are free to rotate via the rotary table  15 , the power tong unit itself is stationary. 
       FIGS. 1 ,  3 ,  4 ,  6 , and  7  also illustrate a multi-function injector head  29 . The injector head is capable of splitting into two halves  30  and  31  so as to move horizontally the halves and radially away from the center line of the well bore. Alternative orientations, 90° apart, are illustrated in  FIG. 1  as compared to  FIGS. 3 and 4 . The configuration will depend on the clearances needed upon retraction or opening and the size and configuration of the other components of the unit, as there is obviously less room to move an injector half  31  toward the gin pole  8  ( FIG. 1 ) compared to moving half  31  unobstructedly (FIG.  4 ). The injector head is mounted above the stationary slips  13  and within the window defined by the jack legs  20  of the hydraulic jack assembly  11 . As with the guide arch assembly or gooseneck  33  which will be described in more detail below, the two halves  30  and  31  of the multi function injector head  29  can move via a guided system  34  away from the center line of the well bore. Hydraulic pistons  35  translate the two halves toward or away from each other as desired and hold them in place. 
     As with the multi function injector head described above, the guide arch assembly  33  is provided with a guide system  36  and suitable means to translate the trolley and the guide arch assembly radially from a position over the center line of the well bore as illustrated in  FIG. 6  to a position out of the way as illustrated in  FIG. 7  so that tubing can be rotated within the well bore. As will be described below, since the tubulars to be spooled in the present invention may be of a larger outer diameter than typical in coil tubing outer diameters; it may or may not be necessary to have a conventional guide arch assembly as long as alignment and a gradual curvature can be maintained from the reel to the injector head. 
     As illustrated in  FIGS. 1 and 7 , present invention also comprises a standpipe  18  for the purposes of fluid circulation with high pressure connections on each end of the standpipe to allow pumping. 
     As illustrated in  FIGS. 1 ,  3 ,  4 , and  7 , the apparatus of the present invention incorporates a gin pole or boom  8  to handle convey casing tubing drilling assemblies and completion tools. A winching system comprising a dual winch  37 , and a multiplicity of sheaves  38  on the top of the gin pole  8  operates with the counter balance winches  6  (a sub component of  37 ), as described for the conventional snubbing.  FIGS. 2 and 3 . 
     As previously referenced,  FIGS. 1 ,  6  and  7  illustrate a window  32  framed by four horizontal supports  39 . The window allows for insertion and extraction of tools in the work string and access to the stationary slips  13 . 
       FIGS. 1 and 4  illustrate a vertical pipe racking or “rack back” system comprising finger boards  40  attached to a frame  41  and/or to the work basket  3 , finger boards are parallel beams with spaces for the tubulars. The finger boards permit multiple joints of jointed pipe to be racked together vertically so as to speed up trip time when using jointed pipe as described previously. The rack back system  10  for racking pipe vertically and multiple joints also includes pipe containment bases  42 . 
       FIG. 5 , illustrates an additional component of the present invention, a spoolable drill pipe system  43 , which comprises a connector  44 , a multi section reel  45  and connection  46  to the reel for fluid circulation. Connector  44  is for connecting reeled drill pipe to pipe joints over the center line of the well and within the combination snubbing and injection apparatus. 
     The invention also contemplates a reel drive mechanism and pipe pulling procedure to allow spooling drill pipe. 
     The work basket  3  contemplated for the preferred embodiment is to be 8 by 8 foot with attachable 3 by 8 foot finger boards, mounted on each end. The work basket would be configured to allow for boom and boom skid plate, the dual counter balance winch package, “V” door and a modular removable operator control console  4 . An alternative embodiment of the present invention contemplates using a remote counter balance control system to allow for freedom of personnel movement while actuating the counter balance winches. 
       FIGS. 9 through 12  illustrate additional sub assemblies of the present invention, primarily the sub assembly which may be required to support the rack back vertical pipe racking assemblies. In some instances, the dry tubing weight can be supported by the earth, the platform  47  or the well head, depending on which base is used for standing the tubing. In other applications, a supplemental structure may be required. As illustrated in the two side elevations  9  and  10  and in the plan view  11 , a three dimensional truss assembly  49  is used to provide the support for the pipe containment bases  42  upon which the vertically racked pipe  48  can be stood. As illustrated in  FIG. 10 , the substructure assembly  49  is asymmetrical to provide a support for the access ladders or walkways  50  on one side of the unit. In those applications they required the access stairways are mounted to a scaffolding assembly  51 . The subassembly can also be configured to rack pipe on only one, or on three sides. 
     The pipe containment bases for the purpose of racking pipe which are attached to the lower support base of the snubbing jack or in the immediate area. A containment base such as as illustrated in  FIGS. 9 through 12 , that transfers the weight to the well head is one option. The primary embodiment contemplates building a containment base transferring the weight to the well head, although another option would be to transfer the weight to a platform or other structure besides the well head. The present invention also contemplates using a combination of these two. The frame or scaffold system connects the containment bases to the finger boards. The total system is designed to withstand the load of the tubulars and account for wind forces. 
     With respect to the above description, it is to be realized that although dimensional embodiments of specific material is disclosed, those enabling embodiments are illustrative, and the optimum dimension relationships for the parts of the invention are to include variations in size, material, shape, form, function and manner of operation, assembly and use, which are deemed readily apparent to one skilled in the art in view of this disclosure, and all equivalent relationships to those illustrated in the drawings and encompassed in the specifications are intended to be encompassed by the present invention.
