Winchester Energy Limited provided an update on its field activities at the Varn Oil Field in Nolan County, Texas. Following the drilling of four initial 300ft surface wells and installation of wellheads by a surface rig, Winchester has moved a larger rig onto the first Varn well, JVU#11WSW, and will extend it to a total depth of 4,900ft. JVU#11WSW is the water supply well for the planned Varn Oil Field waterflood operation. A total of 11 wells, comprising six producers and five injectors, are required for the planned waterflood of the Varn Oil Field. Overview - Varn Oil Field (100% WI). Winchester has a 100% working interest in the Varn Oil Field, located 18 miles to the east of
the Company's existing producing assets in Nolan County, Texas. The Varn Oil Field contains existing Proven and Probable (2P) of 1,068,000 barrels of oil equivalent(boe1) comprised of 994,000 barrels of oil and 442 thousand cubic feet of gas (mmcf). Production is to be derived from the Fry Sands (a sub-unit of the Strawn Sands) which, together with the Ellenburger Formation, is currently producing oil and gas at Winchester's Nolan County operations.
The majority of wells are planned for the central area where the Upper and Lower Fry Sand overlap while the rest of the wells capture oil from the more widespread Upper Fry Sand. Waterflooding is a secondary recovery technique which injects water into an oil reservoir in a downdip position. The water repressurises the field and provides energy to move unswept oil updip to crestal oil well producers.
