ConocoPhilips halts oil flow from two Bohai Bay platforms

HOUSTON, July 13 -- China’s State Oceanic Administration (SOA) requested ConocoPhillips China Inc., operator of Penglai 19-3 oil field in Bohai Bay, to suspend production from Penglai Platforms B and C until the risk of another oil spill is eliminated, CNOOC Ltd. reported.

“Operations aren’t permitted to resume until oil spill risks are fully eliminated,” SOA said in a statement following two incidents from the field last month. Under a production-sharing contract with ConocoPhillips, CNOOC holds 51% interest.

The shutin is expected to result in a temporary reduction of 17,000 b/d net after royalties to ConocoPhillips, the company said. CNOOC said its net production from the two platforms before the shutin was 22,000 b/d.

ConocoPhillips said seepage on the seabed was observed June 4 along a natural fault near Platform B. In a second incident, oil and gas bubbles were observed on the surface June 17 near Platform C, 2 miles from the Platform B seep. The bubbles were seen during drilling from the platform.

“The majority of seepage has been stopped” from Platform B, ConocoPhillips said. “A containment device was designed and constructed and put in place as a precaution should the seep occur from the main source again.”

Trace amounts of oil continue to seep intermittently near the original seep, occasionally causing minor surface sheens, ConocoPhillips said. Workers deployed booms to contain and collect oil.

A cementing procedure stopped the release near Platform C within 48 hr, and the well was stabilized, plugged and abandoned, ConocoPhillips said. Crews deployed absorbent boom, and cleanup operations continue.

ConocoPhillips estimated the aggregate amount of fluid spilled from the two incidents at 1,500-2,000 bbl of oil and oil-based drilling fluids. The company is working with independent experts to validate the estimate.

During these incidents, no oil sheen reached the shoreline, and there were no injuries to personnel, ConocoPhillips said.

An SOA spokesman told reporters in Tianjin, China, on July 12 that the agency is calling for intensified inspections of offshore operations and also is asking for closer coordination with local governments.

Separately, CNOOC reported a minor spill at Suizhong 36-1 oil field (OGJ Online, July 12, 2011).

Oil & Gas Journal’s March 20, 2015, webcast will look at how global LNG trade will be affected over the next 12-24 months by falling crude oil prices and changing patterns and pressures of demand. Will US LNG production play a role in balancing markets? Or will it add to a growing global oversupply of LNG for markets remote from easier natural gas supply? Will new buyers with marginal credit, smaller requirements, or great need for flexibility begin to look attractive to suppliers? How will high-cost, mega-projects in Australia respond to new construction cost trends?

US Midstream at a Crossroads

Fri, Mar 6, 2015

Oil & Gas Journal’s Mar. 6, 2015, webcast will focus on US midstream companies at an inflection point in their development in response to more than 6 years shale oil and gas production growth. Major infrastructure—gas plants, gathering systems, and takeaway pipelines—have been built. Major fractionation hubs have expanded. Given the radically changed pricing environment since mid-2014, where do processors go from here? What is the fate of large projects caught in mid-development? How to producers and processors cooperate to ensure a sustainable and profitable future? This event will serve to set the discussion table for the annual GPA Convention in San Antonio, Apr. 13-16, 2015.

This event is sponsored by Leidos Engineering.
