World Oil Resources (ASX: WLR) is exploring for oil in Kansas.
World Oil Resources ready to frac and test Socrates well, targets up to 300m barrels at WB-W field

World Oil Resources (ASX:WLR) is preparing to fracture stimulate and test the first modern horizontal well on the Welch-Bornholdt Wherry (WB-W) field in Rice and McPherson counties, Kansas.
While, historic wells at WB-W have averaged total recovery of about 50,000 barrels of oil, Scorates-1H was drilled with the aim of demonstrating that modern horizontal drilling and fraccing technology could be used to develop the Mississippian reservoir at WB-W.
These technologies have been used to great effect to increase recoveries of oil-in-place at analogous fields in Kansas and Oklahoma, increasing the likelihood that recoveries at Socrates-1H would be much higher.
The Socrates 1H well was drilled and logged with a total horizontal section of 1280 metres(4201 feet) from the cased and cemented landing point of the curve to the toe of the well at 2423 metres (7950 feet) measured total depth.
World Oil had previously noted the reservoir characteristics of the lateral were better than pre-drilling estimates showing a remarkably uniform lateral section with average porosity of more than 15% along with the presence of oil in samples and at the flowline during drilling.
The first 296 metres (970 feet) of the lateral has been completed using “Packers Plus”, an open hole, multi stage fraccing and completion technology, while the remaining lateral will be open hole.
World Oil is targeting 200 to 300 million barrels (MMbbl) of oil at WB-W, where production had started in 1934 and peaked in the 1960s.
The field contains 1400 vertical wells that provide excellent well control and has produced 46MMbbl of oil to the end of 2011 from original in-place oil of more than 600MMbbl of oil.
World Oil holds a 50% working interest in the 60.6 square kilometre WB-W field while partner CMX holds the remaining 50%.
Other companies targeting the Mississippi play include US players Tengasco (NYSEAMEX:TGC) and Superior Oil & Gas.
