. . Mississippian age would be the most favorable formation for deep well disposal. The following are reasons for selecting this particular scheme: 1) This wel1 is the closest to brine pumping field. 2) Presence of a porous, thick, continous formation to serve as a storage reservoir. 3) The formation is deep enough not to be effected by faults or geologic structure that may cause leakage to the surface. 4) A zone that is vertically far below the fresh water circulation and confined by a thick salt layer above. 5) Existing drill-stem test data, logs, and core informa- tion relate the existence of a reservoir. The data from drill-stem tests and core from the Continental Oil Co. No. 1 - Scorup well showed a vuggy Mississippian Formation between 14,726 to 14,968 feet. In that interval formation (lithostatic pressure) was 3,440 to 6,400#, hydrostatic pressure was 8,760#. Data from the Lisbon oil and gas field, Utah indicates that this formation has a porosity of 30 to 40 percent and a permeability of 1,000 mds. Examples of brine chemical analysis shown in the report are very similar to that of Paradox Valley brine. Mr. Turner calcu- lated that the reservoir capacity for one mile radius from the drill hole would be 13,000,000,000 gallons. In this calculation, no lithostatic or hydrostatic pressures were used to compute the reser- voir capacity. Assuming this total capacity is available for brine disposal, then at a pumping rate of 1 cfs the reservoir would be filled in 55 years; at 2 cfs, its would be filled in 27 years. Taking into account the lithostatic and hydrostatic pressures, the reservoir capacity would be less. , . ~~~.~. ~~~.OG
