- On June 4, 2011, oil sheens were observed on the water’s surface near Peng Lai 19-3 Wellhead Platform B (the B-Event). ConocoPhillips China (COPC) immediately deployed skimmers, absorbent booms and other clean-up equipment. Relevant Chinese government authorities and the China National Offshore Oil Company (CNOOC), our co-venturer, were notified immediately. Once the source was determined to be an existing geological fault that opened slightly due to pressure from water injection into a subsurface reservoir during production activities, COPC began reducing reservoir pressure to seal the source.
- On June 17, 2011, an unanticipated high-pressure zone was encountered at a water injection well at Peng Lai 19-3 Wellhead Platform C (the C-Event). The C-Event was separate and unrelated to the B-Event. The well was immediately shut-in to ensure no danger to the personnel or the platform, but the pressure caused reservoir fluids and mineral oil-based drilling mud to flow to the seabed. COPC was immediately engaged with relevant Chinese government authorities and CNOOC.
- On June 19, 2011, within 48 hours of the C-Event, a cementing procedure stopped the release at Peng Lai 19-3 Wellhead Platform C. From June 18 to June 19 approximately 600 barrels (97 cubic meters) of oil and about 2,620 barrels (416 cubic meters) of mineral oil-based mud were released onto the seabed.
- On June 21, 2011, the reservoir pressure reduction plan at the location of the B-Event successfully closed the fault thereby isolating the reservoir from the surface and stopping the seepage. From the start of the B-Event on June 4 to June 21 approximately 100 barrels (18 cubic meters) of oil seeped from the previously inactive fault.
- On September 2, 2011, COPC suspended all production, water injection and drilling operations in the Peng Lai 19-3 Field in accordance with SOA Order 582. In compliance with Order 582 COPC continued clean-up efforts, focused on ensuring oil seep sources were sealed, prepared a new marine environmental impact report for the oil field, and developed a plan for further reducing reservoir pressure.
- On September 14, 2011, COPC concluded the clean-up of mineral oil-based drilling mud (MOBM) from the seabed. More than 100 divers completed 1,463 dives since the program began at the start of July.
- On October 12, 2011, Shoreline surveillance teams demobilized. In total, the teams covered nearly 155,000 kilometers of shoreline by vehicle and 8,500 kilometers on foot. A total of 83 oily samples were identified during the shoreline surveillance process; quantitative fingerprinting conducted by the most advanced testing laboratories in the world revealed that only three samples contained similar chemistry to the source oil at Peng Lai 19-3 (these were found on the northeast coastline near Suizhong and Qinhuangdao). The remaining samples were unrelated to Peng Lai 19-3.
- On January 24, 2012, ConocoPhillips, together with CNOOC, announced an agreement with the Ministry of Agriculture to settle public and private claims of potentially affected fishermen in relevant Bohai Bay communities. Under this agreement, RMB 1 billion (approximately USD 160 million) was paid to the MOA. The MOA is administering the disbursement of these funds to ensure potentially affected fishermen receive compensation. ConocoPhillips also designated RMB 100 million (approximately USD 16 million) to help improve fishery resources – this is being administered by the MOA.
- On March 12, 2012, COPC signed another agreement with the TEDA International Cardiovascular Hospital in Tianjin, announcing COPC will donate a further RMB 525,000 to the Love & Hope Project to fund surgeries for underprivileged children suffering from congenital heart disease.
- On April 27, 2012, ConocoPhillips, together with CNOOC, announced an agreement with the State Oceanic Administration. Based on the agreement, ConocoPhillips agreed to pay RMB 1.090 billion (approximately USD 173 million) to resolve claims related to the possible impact of the incidents on the Bohai Bay marine environment. ConocoPhillips also agreed to pay RMB 113 million (approximately USD 18 million) to the SOA to support initiatives that enhance marine ecological protection and reduce pollutants in the Bay – this is being administered by the SOA.
- On June 4, 2012, ConocoPhillips announced two environmental sustainable initiatives independently supported by the company-- By-Product Synergy EcoPartnership Initiative and Conservation for the crane flyway from the Hulunbeier steppe to Bohai Sea.
- On December 24, 2012 COPC signed another agreement with the Light & Love School in Beijing, announcing COPC will donate a further RMB 1,248,500 to the Light & Love School which provides free education and accommodation to for migrant workers’ children.
- On December 28, 2012, COPC entered a Joint Study Agreement with Sinopec Southern Exploration Company for the Qijiang shale gas block.
- On January 1, 2013, COPC signed another agreement with the TEDA International Cardiovascular Hospital in Tianjin, announcing COPC will donate a further RMB 1,050,000 to the Love & Hope Project in 2013 to fund surgeries for underprivileged children suffering from congenital heart disease.
- On January 30, 2013, ConocoPhillips China signed a 3-year agreement with Roots & Shoots Beijing Office, under which COPC will donate RMB 3,045,000 to the Clear Water Project and Migrant Children Environment Education Project in China.
- On February 17, 2013, COPC received approval for step by step resumption of production at the PL 19-3 Field.
- On February 20, 2013, COPC announced that it has established a Joint Study Agreement (JSA) for unconventional resource development in Sichuan Basin in China with PetroChina Company Ltd. (PetroChina).
- On June 24, 2013, COPC signed a 2-year agreement with the International Crane Foundation under which COPC will donate a total of RMB 797,000 to conduct Natural School Program which focuses on environment education for primary school students living in wetlands areas in northeast China.
- On July 26, 2013, COPC signed a 3-year agreement with Institute of International Education under which COPC will donate a total of USD 600,000 to establish the China Environmental Stewardship Awards.
