text: **total recordable case frequency rate (TRCFR)**
  A statistical measure of safety performance. 
  Total recordable case frequency rate is 
  calculated as the total number of recordable 
  cases (medical treatment injuries and lost time 
  injuries) per million hours worked. A lost time 
  injury is a work-related injury or illness that 
  results, or would result, in a permanent 
  disability or time lost of one complete shift 
  or day or more any time after the injury or 
  illness. A medical treatment injury is a work- 
  related injury or illness, other than a lost time 
  injury, where the injury is serious enough to 
  require more than minor first aid treatment. 
  Santos classifies injuries that result in 
  modified duties as medical treatment injuries. 
  
  **Proven plus Probable reserves (2P)**
  Proven plus Probable reserves (2P) are those 
  reserves that analysis of geological and 
  engineering data suggests are more likely than 
  not to be recoverable. There is at least a 50% 
  probability that reserves recovered will exceed 
  Proven plus Probable reserves. 
  **wildcat exploration**
  Exploration wells testing new play concepts or 
  structures distanced from current fields.
