Contains open hole drillstem test raw field data, a geophysicist's well velocity survey time/depth calibration report, a ?make-up water sample analysis, the petroleum engineers' proposed programmes for separate pre- and post-frac gas flow and production tests, and related engineering reports for the combined acid ballout stimulation, injectivity testing and massive hydraulic fracture stimulation work carried out on the Tirrawarra Sandstone gas reservoir during December 1984 through February 1985 as part of the Cooper Basin Accelerated Gas Programme. Also contains the results of a reservoir pressure monitoring 324 hour buildup survey conducted in November 1991, and of static wellbore pressure gradient surveys run in February 1986 and December 1991.
