Some methods of fracking shale wells are more effective than others, Rex Energy is finding out.
The State College, Pa.-based driller gave an update Friday on its Utica Shale wells in Carroll County.
Included in the report were the G. Graham 1H and 2H wells in Washington Township, which were completed using different techniques with different results.
In a release, Rex said initial sales from the 1H well are among the best results in Carroll County so far, but results from the 2H well next to it have been below expectations.
During hydraulic fracturing, or fracking, drillers use high-pressure water, chemicals and sand to break up the shale, thereby releasing the natural gas and oil trapped inside.
The 1H well averaged a 30-day sales rate of 1,256 barrels of oil equivalent a day, with a split of 46 percent natural gas liquids, 33 percent natural gas and 21 percent condensate, assuming full ethane recovery and a natural gas shrink of 36 percent.
Rex drilled the 1H well to a total depth of 12,098 feet with a lateral length of 3,973 feet, and used it’s own “Super Frac” technique to complete the well in 27 stages.
On the 2H well — drilled to 11,776 feet with a lateral length of 3,572 feet — Rex used a third-party completion technique in 24 stages. The company is still reviewing the method, but preliminary results were below expectations and Rex plans to use “Super Frac” on all future completions planned in the Appalachian Basin, according to a statement.
The company used the “Super Frac” method to complete its two-well Brace West pad in Washington Township during the second quarter, and plans to place the wells into sales early next month.
Rex also has three wells producing in Noble County, is drilling the fourth of five wells in Guernsey County, and last week obtained permits for five more wells in Carroll County.
