(Bloomberg) -- Pipeline owners near a crucial Oklahoma oilhub reported little damage and resumed normal service after amagnitude 5 earthquake struck late Sunday.

Oklahoma’s oil and gas regulator reported that all pipelinesunder its jurisdiction were operating again after shutting down asa precaution because of the temblor, centered less than 2miles west of the city of Cushing.

It’s the second sizable quake in the past two months for thearea, which serves as a delivery point for West Texas Intermediatecrude and sets the benchmark U.S. oil contract price. Oilfutures rose 38 cents to $44.45 a barrel at 10:34 a.m. on theNew York Mercantile Exchange.

“It’s definitely a long-term negative development if you aregetting earthquakes of that magnitude at such an important site,”Bob Yawger, director of the futures division at MizuhoSecurities USA Inc. in New York, said by telephone. “It doesn’tbode well for the future.”

The Oklahoma CorporationCommission hasn’t ordered the shutdown of any waste-waterdisposal wells in the area after the earthquake, Matt Skinner,a spokesman for the agency, said by phone. The regulator “isworking on an action plan” regarding disposal-well operations inthe Arbuckle formation, according to an e-mailedstatement. When a similar-magnitude quake hit the state inSeptember, the agency ordered 37 wells shut.

Controlled shutdow after quake

Magellan Midstream Partners LP, a pipeline operator, resumed normaloperations at Cushing late Sunday after a controlled shutdown ofits assets after the quake, spokesman Bruce Heine said in e-mailedstatements. Enbridge Inc. spokesman Michael Barnes said by emailthat there was no effect on the company’s facility in Cushing.

Magellan typically discontinues operations to check theintegrity of assets if an earthquake over a certain strengthoccurs, Heine said. Kinder Morgan Inc., another pipe operator,hasn’t had any issues affecting its Cushing operations, RichardWheatley, a Houston-based spokesman for the company, said in ane-mailed statement.

Electricity has been restored to almost all of Cushing, about 70miles northeast of Oklahoma City, Jeremy Frazier, assistant citymanager, told reporters at a televised press conference lateSunday. Authorities have been in contact with tank farms in thearea and there has been no damage to terminals, he said. While somegas leaks occurred, they have been contained and are no longer athreat, according to Frazier. There was some structural damageto buildings in the city’s downtown area, he said.

Other tremors

Several producers, as well as the U.S. EnvironmentalProtection Agency, are facing lawsuits because of seismicactivity allegedly linked to oilfield wastewater disposal inOklahoma and other states. The OCC, which regulates oil and gasactivity in the state, has been issuing restrictions for more thana year aimed at cutting down on the amount of wastewater injectedinto underground wells.

There are about 35,000 active wastewater disposal wells, thoughonly a few dozen have been linked to quakes, according to aBloomberg Intelligence report in May, citing the USGS. A 5.6magnitude tremblor had struck Oklahoma in September, which tied astate record set in 2011. Following earthquake at Cushing onSunday, minor tremors occurred at Nicoma Park, east of OklahomaCity, and Fairview, in the western part of the state.

The region, previously not known for intense seismic activity,began having a significant number of earthquakes in 2009, the sameyear area oil companies began using fracking to shatter deep rocklayers to extract oil and gas. Fracked wells produce largequantities of wastewater, which drilling companies inject intoultra-deep disposal wells.
