Well Log Quality Control: What You Don't Know Can Hurt You
Well Logs form the foundation upon which Oil and Gas reserves are based. Logging vendors are responsible for delivering data that has been acquired with instruments what were calibrated and run properly, providing documentation of this in both delivered hard and soft copy data.
The client representative needs to verify that this has been done, before signing the vendor invoice, as the logging witness. Failure to do so can have severe repercussions, if “Stated Reserves” include data from miscalibrated and/or improperly run logs.
Simple, straight-forward, well-site techniques are demonstrated which will allow the client representative to quickly determine if the vendor has properly done their job.
