| Description |
| |
Discovered in 2006, Chim Sao, formerly Blackbird, is located on Block 12W and 12E in 377 feet (115 meters) of water, around 248 miles (400 kilometers) southeast of Ho Chi Minh City, offshore Vietnam. Premier serves as the operator of the oil and gas field, holding a 53.125% interest. Partners on the field include Santos (31.875%) and PVEP (15%).
Exploration
The Chim Sao discovery well, (12E-CS-1X), found four oil bearing intervals in the main Middle Dua target, intersecting more than 230 feet (70 meters) of net pay. Two years later, the partners further appraised the field and successfully drilled the Chim Sao North appraisal well. The well was drill stem tested and flowed oil at a sustained rate of 1,650 bopd and 1.4MMcf/d (.04 MMcm/d) on a 40/64-inch choke. The second production test flowed at a rate of 2,680 bopd and 2.1MMcf/d (.06 MMcm/d) on a 48/64-inch choke.
This result led to the well being sidetracked down-dip to delineate the oil/water contact and the extent of the hydrocarbon-bearing reservoir. The Chim Sao North well, suspended as a future producer, was appraised to optimize the field's development plan.
Field Development
Once Chim Sao was appraised, a field development plan was submitted to authorities, receiving government approval in April 2008. The first phase of the field development plan includes two wellhead platforms tied-back to the Nexus 1 FPSO. The FPSO will have the capacity to process up to 25-30,000 bbl/d, then offload oil to shuttle tankers. Gas will be exported via a spur and then through PetroVietnam's Nam Con Son 62-mile (100-kilometer) gas pipeline.
BW Offshore submitted a bid to provide both the provision of the FPSO and for an EPCI contract for the surface facilities.
As for the rest of the field development, contractors were selected and work commenced on the field's development. Production commenced on October 10, 2011.
Further Exploration
The partners contracted the Wilboss jackup for a three- to four-well exploration campaign in the first half of 2009 to further appraise the area to find additional oil discoveries that can be tied-back to the Chim Sao development.
The operator is developing the Dua field as a subsea tie-back to the Chim Sao project. In December 2011, the Government of Vietnam approved the outline development plan for the project, and placed orders for the necessary equipment to develop the field. Full production from the field is slated for early December 2014.

|
| EOC Bags FPSO Upgrade Project |
Date: Oct. 2012
Type: Development Activity |
| Premier Oil awarded a $15 million contract to EOC Limited in relation to the upgrade of FPSO Lewek EMAS. Under the contract, EOC will provide project management, engineering and procurement services for modifications that are necessary to accommodate a subsea tie-back that will link the vessel to the nearby Dua oil field in Block 12E offshore Vietnam. The Lewek EMAS is currently in operation in the Premier-operated Chim Sao field. Once the project is completed in late 2013, the FPSO will produce both fields. All modifications will be made in the field without taking the vessel offline. |

| Premier Reaches TD on Chim Sao NW Appraisal Well |
Date: Aug. 2012
Type: Development Activity |
| Premier Oil reported that the Chim Sao North West appraisal well, CS-3X, has reached a total depth of 13,894 feet (4,235 meters). The well has been plugged and abandoned after encountering oil shows in the Middle Dua sands. The appraisal well was drilled to determine whether the Chim Sao North West discovery extended into a separate fault segment to the north. The well targeted the Upper and Middle Dua sands. While 443 feet (135 meters) of sandstone reservoir were penetrated in the Upper Dua interval there was no indication of hydrocarbons. In the Middle Dua interval 541 feet (165 meters) of sands were drilled, but only oil shows were encountered. The CS-N17XP well, which was completed immediately prior to the appraisal well, was drilled to produce from the North West extension to the Chim Sao Field. That well was brought on-stream earlier this month with initial extended production test rates averaging 4,000 barrels of oil per day from four Upper Dua reservoirs. |

| Premier Oil Moves Forward with Dua Development |
Date: May. 2012
Type: Status Update |
| Premier Oil announced that the Dua project, a tie-in to the Chim Sao field, was formally sanctioned by Premier and Santos in April. It is expected that the necessary Vietnamese government approvals will be received during the second quarter of 2012. In the meantime, bids for FPSO modifications and the drilling rig have been received and are being evaluated. Premier continues to target 2014 for first oil. |

| Premier to Bring Additional Wells Online at Chim Sao |
Date: Apr. 2012
Type: Status Update |
| Premier Oil reported that by year-end 2011, close to 2 MMboe had been produced from six production wells on the Chim Sao field, which came online in October 2011. An additional three production wells will be available to come on-stream in early 2012 when the four-well water injection system will come online. Furthermore, a well deepened into the Oligocene directly beneath the main field proved an estimated 56 feet (17 meters) of net hydrocarbon-bearing pay, and an additional well to be drilled in early 2012 will accelerate production from a shallow reservoir that has larger reserves than initially estimated. The CS-N2P well, a development production well for the Chim Sao project, intersected the shallow part of a previously undrilled fault terrace to the northwest of the Chim Sao field. The well encountered a 66 feet (20 meter) oil column in an independent closure within good quality Upper Dua sandstones. The plan is to further appraise this new accumulation in 2012 as a near-field tie-back opportunity. |

| Premier Oil Begins Production at Chim Sao |
Date: Oct. 2011
Type: Production Start |
| Premier Oil has commenced production from the Chim Sao oil project offshore southern Vietnam. Oil production will commence from six wells, and overall production output should plateau at about 25,000 bopd. The field's development consists of a single wellhead platform and an FPSO. Hydrocarbons will be processed on the FPSO with oil being exported via shuttle tankers and the gas by subsea pipeline into existing gas infrastructure. The operator plans to further explore and appraise the development in 2012 in order to add additional resources to the project. Chim Sao is located on Blocks 12W and 12E in 377 feet (115 meters) of water, around 248 miles (400 kilometers) southeast of Ho Chi Minh City, offshore Vietnam. Premier serves as the operator of the oil and gas field, holding a 53.125 percent interest. |
