panels, so damaged sections can be individually repaired to prolong the screen life. Traditionally, a screen is disposed entirely when only 15% screen area is damaged, this approach wasted over 85% of non-damaged screen area as well as the frame. For oilfield activity in remote environment, the reduction to waste and logistics proved to be a significant benefit. Pyramid Screen technology - this technology is a method for increasing the screening area of a shale shaker without the need to build larger machines. When seen from the side these screens look like corrugated cardboard, having a flat bottom and wave like shapes on top. These waves are designed to increase the surface area of the screen panel by building up instead of out, thereby maximizing the surface area of the screen without the need to build larger shaker screens and in turn larger, heavier and more expensive shakers. There are many proven studies by Derrick solutions in regards to the reason for the improved performance of these 3D screens such as: Increasing the screening area of each panel transfers the load across more surface area and therefore the wear tends to be decreased in comparison to other screens. The corrugated shape of the screens encourages solids to settle in the valleys of the screen, keeping the peaks of the screen available to process drilling fluid. The tapered valleys, while moving under high G's, apply a compression force on the solids similar to wringing out a cloth to draw out liquid. Increasing the surface area of the shaker allows the use of finer screens earlier in the drilling process while maintaining acceptable flow rates and penetration rate. Effectively removing harmful drilled solids before they can begin to wear out the solids control equipment. There are many theories on screening performance that yields inconsistent results. The only way to truly gauge the performance of any screen is to try it out and collect comparative data of your own. Causes of screen failure The causes of premature screen failure are: Mishandling of screen panels during storage Improper handling during installation Improper installation of shaker screen to shaker basket Over/under tensioning Dirty, worn, or improperly installed deck rubbers Improper cleaning of the screens while in storage Extremely high mud weight Heavy solids loading Improperly manufactured screens Use of high pressure wash guns to clean or un-blind screens API standards The American Petroleum Institute (API)
