Regulators in Oklahoma ordered Roan Resources Inc. to halt completion operations at an oil well after the Midcontinent region was struck by a 3.4-magnitude earthquake on Sunday evening.

The Oklahoma Corporation Commission’s (OCC) Oil and Gas Division said Monday the “shutdown of the operation is indefinite, pending further investigation and data review.” According to the Oklahoma Geological Survey, the temblor struck the town of Bridge Creek, in Grady County, at 6:53 p.m. The town is about 30 miles southwest of Oklahoma City.

OCC spokesman Matt Skinner told NGI’s Shale Daily that the well in question was a Victory Slide well, an unconventional well drilled with three laterals, each two miles in length.

Roan holds 154,000 net acres in central Oklahoma, about 65 miles southwest of Cushing. The company’s position includes portions of the Sooner Trend of the Anadarko Basin, mostly in Canadian and Kingfisher counties, aka the STACK, and the South Central Oklahoma Oil Province, aka the SCOOP. Sandwiched between them both is the Merge prospect, a legacy area with several zones Roan intends to target. Grady is in the Merge and SCOOP areas.

The company is scheduled to announce its 3Q2018 results next Monday (Nov. 12).
