Marathon Scores 5 Pilot Wells in Oklahoma’s STACK

Houston, Texas-based Marathon Oil Company’s is one of the latest energy companies to find success in Oklahoma’s STACK. The company recently completed 7 wells in the STACK, five at one site near Kingfisher.

The five wells were located at 8 16N 7W or about one mile northwest of the Kingfisher airport. The five Yost wells brought in oil production of 795, 402, 402, 915 and 417 Boe daily. Completions were made in January and February of this year. Marathon also had a completion of the McCarthy well at 35 15N 6W or about 8 miles due east of Okarche.

In its recent quarterly report, Marathon noted that its “unconventional Oklahoma production averaged 44,000 net Boed during the first quarter 2017.”

“Of the 12 gross operated wells brought to sales in the first quarter, five were part of the Company’s first operated STACK infill spacing test, the Yost pilot and the others were focused primarily on STACK lease retention and delineation.”

Marathon explained the Yost pilot successfully tested 107-acre well spacing with completions of approximately 2,500 pounds of proppant per lateral foot. The 30-day initial production rates from the five new standard-lateral Yost wells and parent well averaged 990 Boed with 57% oil.

But Marathon also reported completion of a 315-barrel a day well in Canadian County. The Davis well is located at 16 12N 6W or about two miles due north of the town of Banner. Completion was made in November 2016.

As a result of the growing success, Marathon said it ended the quarter running seven rigs and plans to average approximately 10 rigs in 2017.
