Yardeka #1 is the first well to be drilled in Breitling’s newly developed gas field in the basin.
There are two major objectives within the prospect, the Jefferson Sand at 3450′ and the Upper Gilcrease Sand at 2300′, and secondary objectives include the Spiro Sand at 2800′, the Booch Sand at 1600′ and the Bartlesville Sand at 1150′.
The initial test well will be a 3500′ Jefferson Sand test, and the Jefferson Sand is an excellent reservoir which is found productive on localized structural closures, the company said.
Subsurface mapping on the Wapanucka Limestone indicates a possible northwest to southeast trending structural ridge over the Breitling-Yardeka prospect.
Within this structural ridge there are several structural closures, three of which have produced from the Jefferson.
The well is expected to reach total depth in about four days, and well completion and testing would begin during the third week of April 2011.
