The WSJU #146 well was perforated in the Upper and Middle Red Fork sand reservoirs with six shots per foot from 7,860 - 7,870 feet and 7,910 - 7,920 feet. After perforating both intervals, the well showed 1,500 psi shut in pressure, but only flowed at a rate of 25 Mcf per day. The intervals were then fracture stimulated at the same time using 80,000 lbs. of sand, N2, CO2, and 1,250 barrels of load water. The average treating pressure was 6,600 psi at 25 barrels per minute conducted through 3 1/2" tubing. Offsetting production in Short Junction Field (the Field) from the WSJU #117 (Joe Straka #2) has produced over 500 million cubic feet of gas and is still producing approximately 100 Mcf per day.
DeGolyer & MacNaughton recently estimated that a substantial portion of the 6+ billion cubic feet (Bcf) of proved developed non-producing gas in the Field representing previously bypassed pay in the Pennsylvania sands above the Hunton reservoir can be exploited by perforating existing Hunton well bores up hole and fracture stimulating those reservoirs. The Pennsylvania sand reservoirs are comprised of the following members from top to bottom: the Bartlesville, Prue, Red Fork and Skinner sandstones; all of which are present and appear to be productive on existing Field well logs.
According to Chris A. Dittmar, EnDevCo CEO, "The successful stimulation of the WSJU #146 well will lead to several additional Red Fork completions in the Field. While the long term success of the Field lies with drilling horizontal wells in the Hunton limestone reservoir, the relatively low cost re-completions in the Pennsylvania sand formations are capable of producing substantial increases in natural gas production estimated to be worth $3.5 million dollars per completion over the life of each well. It is important to note that the Field has the infrastructure in place to market the gas as soon as it is produced and is capable of handling an additional 5 million cubic feet of gas per day with no additional capital expenditures."
