HOUSTON, June 7 /PRNewswire/ -- As a result of a recent well control incident during the final stages of completing the Punxsutawney Hunt Club #36H natural gas well in Clearfield County, PA, EOG Resources, Inc.(NYSE: EOG) (EOG) is cooperating fully with the Pennsylvania Department of Environmental Protection (PADEP) and has voluntarily suspended operations in the Commonwealth of Pennsylvania, effective immediately.

In Bradford and Clearfield Counties where EOG has been operating a four rig drilling program, EOG has suspended drilling operations for up to seven days. Hydraulic fracturing operations have been suspended for up to 14 days and post-fracture completion and well clean-out operations have been suspended for up to 30 days. EOG will cooperate with the PADEP in the event these time periods need to be modified. During the suspension period, both EOG and the PADEP will be conducting thorough reviews of EOG's operations. EOG has hired an independent industry expert who has already begun an investigation into this incident and these findings will be shared with the PADEP.

"EOG regrets this incident and will continue to cooperate and work with the PADEP and other Pennsylvania authorities," said Gary L. Smith, Vice President and General Manager, Pittsburgh. "After the investigations are complete, we will carefully review the findings with the goal of enhancing our practices. When all outstanding issues are resolved, we look forward to resuming full operations in Pennsylvania."

The incident occurred at approximately 8:00 p.m. EDT on Thursday, June 3, 2010 when a service rig operated by a contractor was in the final stages of completing this natural gas well prior to bringing the well on production. When the incident occurred, containment trenches and sump pumps were immediately put in place to capture fluid release and well control specialists were dispatched to the wellsite. At sundown, for safety reasons, the area was secured and all personnel were moved away from the well site. The following morning the well control specialists and EOG assessed the situation and took steps to shut-in the well. They determined that no detectable amounts of natural gas were present in the area of the well. The PADEP was notified of the situation and representatives of the agency were also on location to oversee the securing of the well. At approximately 12:15 p.m. EDT on June 4, 2010, the well was secured and shut-in. The well site is in an unpopulated location approximately 11 miles from Penfield, PA. There were no fires, no injuries and no significant impact to the environment as a result of this incident.

During the 16-hour period, the well released a limited amount of flowback water, salt water and some natural gas, but the well has been completely shut-in and secured since approximately 12:15 p.m. EDT on June 4th. The containment trenches and sump pumps captured the majority of the fluids that flowed from the well during this time period. As of the morning of June 6, 2010, approximately 834 barrels (35,000 gallons) of these fluids had been recovered and are contained on location. EOG believes this is the majority of the fluids that were released from the well prior to being shut-in. EOG also immediately began monitoring nearby streams and springs to identify and respond to any impact to area water. At this time, EOG believes that any impact to area streams and springs and to the environment is minimal. All operations at this well site have been suspended and all applicable equipment has been secured pending the incident investigation.  

In a preliminary assessment of the cause, it appears that the seal integrity between the pipe rams of the blow-out preventer (BOP) and the tubing was compromised allowing pressurized fluids and some natural gas to flow. The cause of this compromise is being investigated. As part of EOG's routine operating and safety procedures, the BOP had been successfully tested the morning of June 3, 2010.

EOG does not expect these voluntary suspensions to impact its previously issued 13 percent total company production growth target for 2010. Current EOG production in the Pennsylvania Marcellus Shale is approximately 11 million cubic feet per day, net, less than 1 percent of the company's current total daily production volumes.

In the Pennsylvania Marcellus, EOG has been operating a four rig drilling program. Two smaller rigs have been used to initially drill the vertical sections of the wells. Once the vertical sections are drilled, the rigs move off location to allow larger primary drilling rigs to complete the drilling operation. EOG has been operating two larger primary drilling rigs with deeper extended reach to drill the horizontal sections of the Marcellus well locations.
