.../98. Reanalysis of the BVW showed the reservoir around the wellbore was water undersaturated as is shown in calculations later in the paper. The well was reperforated 30/09/98 with a 101mm EHSC gun using 36 gm 18 SPM 60° phased charges. The next day, the well was re-fraced with 2 tonne 100 mesh sand...

... the surface valve is open. The method of testing described uses the same mass balance equations developed for closed chamber testing, but extends their application. The extensions remove the assumption that the flowrate is constant when the prover is being vented. They also provide the ability to calculate...

.... ABSTRACT Calculations of water saturation were carried out for the A Sand of the Bridger Lake Field using techniques based on: (1) capillary pressure measurements, (2) old well logs and old conventional interpretation charts, and (3) cross plot and pattern recognition. It was found that approaches (1...
