Contains results of rigorous physical analyses of 3 core samples from the Patchawarra Formation gas reservoir interval 9313-9667 feet for structure, rheological properties and fluid transmissivity, plus design recommendations for a future massive hydraulic fracture treatment program for enhancing natural gas production, and a consultants report on the petrology and reservoir quality of the conglomerate interval in Big Lake 29 and Big Lake 30. Other Envelope contents comprise various field static wellbore pressure survey reports, an engineers interpretation of the post-perforating cleanup flow test of 30 May-5 June 1984, and the results and a reservoir engineers interpretation of the pre-frac, multi-rate gas production test of the Patchawarra reservoir interval 9004-9065 feet conducted over the period 28 November-26 December 1984.
