Lundin Successfully Flows Permian Oil in Barents Sea

Oct 2, 2013 – Lundin Petroleum completed a production test on the Permian carbonate reservoir encountered in the previously announced Gohta discovery. During the test, a maximum flowrate of 4,300 bopd was achieved through a 44/64″ choke with a gas/oil ration of 1,040 standard cubic feet per barrel. Flow properties were stable for over 24 hours with pressure build-up lasting 36 hours. Gohta is the first successful flow test of Permian carbonate reservoirs on the Norwegian shelf. Early estimates of Gohta oil and gas resources indicate the possibility of between 105 and 235 MMboe.

Dana and Partners Spin the Bit at Pharos

Oct 2, 2013 – Drilling is underway at the Pharos prospect in UK North Sea license P1566. Well 47/5d-6 is being drilled by the Noble Lynda Bossler (250′ ILC) and is targeting an estimated 500 Bcf of natural gas in the Rotliegendes formation. The large prospect covers portions of blocks 47/4d, 47/5d and 47/10c and is thought to contain nearly three times the amount of gas as the 2010 Platypus discovery just over 8 miles away. If successful, it is possible that Pharos and Platypus could be developed as a single project. Partners in the license include Dana Petroleum (35%) as operator, Parkmead (20%), Dyas Exploration (15%), MPX (15%) and Hansa (15%).

Lundin Continues Johan Sverdrup Appraisal Success

Oct 1, 2013 – Lundin Petroleum’s most recent Johan Sverdrup delineation well encountered an oil column approximately 20 feet thick in excellent quality Upper Jurassic sands in the south western portion of license PL501. Well 16/5-4 was drilled by the Bredford Dolphin (mid-water semisub) to a depth of 6,808 feet. A pressure gauge was installed down hole to monitor pressure development in the reservoir over a period of 2 to 5 years. The rig will now move to the southeastern flank of Johan Sverdrup to drill the 16/3-7 appraisal well.

Island Innovator Spuds Torvastad Wildcat

Oct 1, 2013 – Lundin Petroleum announced the start of exploratory drilling with the spud of well 16/2-20S at the Torvastad prospect just north of the Johan Sverdrup discovery in license PL501. The well is designed to test the northern extension and quality of the Jurassic reservoirs found in Johan Sverdrup. The well will be drilled by the Island Innovator (mid-water semisub) to a depth of 6,807 feet. Lundin, the license operator, expects the rig to be on location for 55 days. Equity holder in PL501 include Lundin (40%), Statoil (40%) and Maersk Oil (20%).

Te Giac Trang Well Test Confirms Robust Resource Base

Oct 3, 2013 – SOCO International announced the results of a production test conducted on the TGT-10XST1 well which was recently drilled at the Te Giac Trang field off Vietnam. The well cut through over 800 feet of pay in Oligocene and Miocene reservoirs. Three zones were evaluated during the test which was carried out over one Oligocene and two Miocene sections. Testing achieved a combined average flowrate of 27,600 boepd. The well is one of the most prolific ever drilled off the coast of Vietnam.

Salamander’s Ayutthaya Well P&A’d as Dry Hole

Oct 1, 2013 – Salamander Energy reached total depth at the Ayutthaya well in Block G4/50 in the Gulf of Thailand. The well was drilled to 7,526 feet and encountered excellent quality reservoirs prognosis. Unfortunately, no signs of hydrocarbons were seen while drilling or on wireline logs. The well has been plugged and abandoned.

BG Group Conducts Successful Pweza DST

Oct 3, 2013 – BG Group’s Pweza discovery appraisal program continues to be successful. The Deepsea Metro I (UDW drillship) drilled the Pweza-3 well to total depth and conducted a 5-day drill stem test (DST) that delivered a maximum flowrate of 57 MMscfd. The results were constrained by testing equipment which shows that Pweza development wells could be capable of flowing at much higher rates. The rig will now relocate to Block 1 to drill the Mzia-3 appraisal.

Delek Group Reports Successful Production Test at Aphrodite-2

Oct 1, 2013 – Noble Energy, operator of Block 12 in the Cyprus Exclusive Economic Zone, carried out a successful production test at the Aphrodite-2 appraisal well. The test was performed onboard the Ensco 5006 (DW semisub) for a duration of 5 days. Delek Group, a junior partner in the well, reported an average flow rate of 32.7 MMscfd with an initial reservoir pressure of 8,961 psi. No appreciable decline in pressure was observed. Well test results were constrained by the testing equipment. Once the well is secured the rig will sail back to Israeli waters to drill the South West Tamar exploration well in the Eran/353 license.

Karoon Planning Kangaroo Appraisal in Santos Basin

Oct 3, 2013 – Karoon Gas Australia continues to progress engineering and geotechnical studies related to its Kangaroo oil discovery off Brazil. Kangaroo and the undrilled Kangaroo West prospect will be the focus of Karoon’s Phase 2 drilling program in the Santos Basin. The Karoon-2 appraisal well is being planned as a priority to confirm the size of the oil column and to confirm the reservoir properties and continuity up-dip from the discovery well. Kangaroo West-1 will be drilled as the second well in Phase 2 due to its potential size which could be in excess of 150 million barrels and proximity to the main field. Additionally, Karoon contracted Worley Parsons and Intecsea to undertake pre-FEED studies for the development. If the Kangaroo work program yields positive results first oil could be seen as early as 2018.

Santos Pulls the Plug on Production at Sangu

Oct 2, 2013 – Production at the Sangu gas field has come to an end after several years of steady decline in production rates. Sangu is the only gas field off the coast of Bangladesh. Santos, the operator, made the decision to shutdown the operation as it was only able to produce 2.4 MMcfd which is far below the 15 MMcfd needed to make the project economically viable. As part of the Production Sharing Contract Santos will hand over control of the platform, subsea pipeline and onshore processing plant to state-run Bangladesh Oil, Gas and Mineral Corporation, or Petrobangla.

Total Transfers Block 2(c) Interest to NGC Trinidad & Tobago

Oct 3, 2013 – Total announced the receipt of regulatory approval for a transaction that will see the company transfer its 30% working interest in Block 2(c) to The National Gas Company of Trinidad & Tobago (NGC) for $437 million. Block 2(c) contains the producing Angostura, Aripo, Canteen and Kairi fields that make up the Greater Angostura Area. NGC’s share of production from the fields will amount to approximately 15,000 beod. Total’s divestment of these assets is in line with the company’s strategy of freeing up capital to focus on areas that possess higher growth potential.

BPZ Updates Development Drilling Program Off Peru

Oct 1, 2013 – Development drilling is underway at the Albacora field in Block Z-1 off the coast of Peru. BPZ Energy announced the spud of the A-18D well from the Albacora platform. It is expected to take twelve weeks to reach the proposed total depth of 12,000 feet. Development drilling at the Corvina field commenced in July with the CX15-1D well. Results from the well are expected in October. BPZ, the field operator, and its partner Pacific Rubiales plan to drill at least 2 wells at Albacora and 3 well at Corvina as part of the development program.

Project Details: Albacora
