Palmer-1-28 was the first well to be drilled by Tomahawk, in the new 10-9 area, which is about 15km west of the company’s existing production wells.
The company has a 100% working interest in the well, which was drilled to a total depth of 1293 metres. It encountered oil and gas in several of the secondary objectives and had significant gas shows in the primary objectives – the Mississippian Caney and Woodford Shales.
The company said the discovery “confirms the tremendous extent and potential growth of the gas shale play.”
“Core samples are expected to confirm the predicted percent of total organic carbon (TOC) and thermal maturity of the area extending the known shale gas window,” said chairman Tony Brennan.
Conventional zones with potential for oil and gas production include the Misener, Cromwell, Gilcrease, Booch, Senora, Calvin and Wewoka sandstones – all of which have a history of production in the area, according to Brennan.
“Strong gas kicks were observed in the Mississippian Caney, with moderate gas kicks being observed in the Woodford shale,” he said.
“A four foot interval of Henryetta coal and ten foot black organic shale overlying the coal seam also yielded a strong gas kick on the hot wire.”
Meanwhile, a electric logs were run to fully evaluate the shales in the new drilling area, as well as fifty sidewall rotary cores cut at intervals throughout the wellbore with concentration on the shale intervals, he said.
Brennan said Tomahawk held drilling options on 4000 acres in the 10-9 Area, which is four times the size of the producing properties where the company’s initial wells were drilled.
Palmer-1-28 was the first well drilled by Tomahawk in phase two of the 2005 drilling program and the 16th well to be drilled on the Oklahoma project.
“The 2005 wells have twice the economic impact to those drilled in 2004, which is significant given that the natural gas price in the US currently exceeds US$14 per thousand,” said Brennan, alluding to the company's 100% working interest in this year's program.
