Abstract

Production testing of three Mississippian sheets in Gulf-Sun-BP Stolberg 6-1-42-15 identified a need to resolve conflicts in wellsite data before completion procedures are initiated or concurrent with them. Excel- lent agreement was observed between samples, gas detector readings and wire- line logs on the first two Mississippian thrust sheets, in this mountain front deep test and productivity was confirmed by production testing. How- ever, on the third sheet, wireline log interpretation conflicted with litho- logy and gas detector indications. Resolution of the conflict was achieved well after the fact but might have resulted in considerable cost savings if made concurrent with production testing.
