Dussafu Marin is operated by Harvest Dussafu (66.67%), an affiliate of Harvest Natural Resources. Panoro Energy has a 33.33% stake, held through a subsidiary company.
Lundin Petroleum completed Tembakau-1, a well sited in the PM307 Block, offshore Malaysia, as a gas discovery. Tembakau-1, a vertical well drilled to a depth of 5,135 ft in 220 ft water depth, penetrated around 197 ft of net gas pay in five high-quality sand intervals in the Miocene objective. Lundin (75%) is operator, with Petronas Carigali (25%).
The Su Tu Trang field offshore southern Vietnam started gas production 1 month ahead of schedule. The field in Block 15.1 in the Cuu Long Basin is operated by the Cuu Long Joint Operating Company (JOC). Operations at the field have raised Cuu Long JOC’s daily output to 1.3 million m3. The Cuu Long JOC is also producing 40,000 BOPD. The JOC is 50% owned by PetroVietnam Exploration and Production, with ConocoPhillips (23.25%), Korea National Oil Corporation (14.25%), SK Innovation (9%), and Geopetrol (3.50%).
Bengal Energy’s first exploration well in the Tookoonooka drilling campaign, Caracal-1, is a new oil discovery, located on the southeast flank of the Cooper Basin about 25 miles southeast of the producing Ipundu/Tarbat oil fields. The well was drilled as a vertical well and, after being perforated, recovered free oil on swab testing commingled across two different sands in the Wyandra formation. This is the first well in 15 years to be drilled on the 654,335-acre Authority to Prospect 732 Tookoonooka Block. Engineering and geological work is planned by Bengal to determine how horizontal multistage fracturing could be applied at Caracal. Bengal (100%) is operator.
Exploration of the Asha/Noor prospect in the Norwegian North Sea has commenced. Well 16/1-16 is being drilled in 370 ft of water on the western edge of the Utsira High area and is targeting four reservoirs assumed to be Upper Jurassic sandstones. In addition, the well has the potential to appraise the neighboring Ivar Aasen and Apollo discoveries. Wintershall Norge (40%) is the operator, with VNG Norge (20%), Bridge Energy (20%), and E.ON Ruhrgas Norge (20%).
Well 34/6-2S on the Garantiana prospect offshore Norway was drilled to a total depth of 13,287 ft in about 1,247 ft water depth. The well, located in Production License 554, penetrated good-quality oil-bearing reservoir rock in the Cook formation. A sidetrack well will be drilled to define the oil-water contact. Total (40%) is the operator, with Bridge Energy (20%), Det norske (20%), and Svenska (20%).
DNO International’s 423-km2 Block 8 concession offshore Oman hit record production, climbing to a rate of 20,000 B/D of oil and condensate along with 60 MMcf/D of gas. The increase, which represents a near tripling of oil and condensate production and near doubling of gas production from the block, was due to a two-well drilling program conducted by DNO in the West Bukha field. Block 8 contains Oman’s only offshore producing field. DNO (50%) is operator, with Korea’s LG International (50%).
Talisman Energy discovered a significant accumulation of light oil at the onshore Kurdamir-2 well in the Kurdistan Region of northern Iraq. A cased-hole test was conducted in the deeper part of the Oligocene formation, targeting about 65 ft of fractured reservoir below the main porous zone. The well tested at stabilized rates of up to 3,450 B/D of 38°API oil and 8.8 MMcf/D of natural gas over a 2-day period. Talisman (40%) is operator of the Kurdamir Block, with WesternZagros (40%) and the Kurdistan Regional Government (20% carried interest).
Magnolia Petroleum spudded the Roger Swartz No. 1 well, its first well as operator in the Mississippi Lime formation, located in Noble County, Oklahoma. Targeted total depth is 5,500 ft. Magnolia, which currently has a 100% interest in the well, has made a farm-in deal in which third parties can acquire a 16.25% working interest once a payout has been achieved.
BP Trinidad & Tobago announced it has discovered an estimated 1 Tcf of gas offshore Trinidad, doubling the estimated gas in place of the Savonette gas field to 2 Tcf. The Savonette 4 appraisal well was drilled into an untested fault block east of the original Savonette field discovery well, in water depths of almost 300 ft in the Columbus Basin about 50 miles off the southeast coast of Trinidad. The well was drilled to a total depth of 18,678 ft and penetrated hydrocarbon-bearing reservoirs in two intervals. BP (100%) is the operator of Savonette 4.
Statoil completed its first multilateral well offshore Brazil as part of the company’s increased oil-recovery efforts at the Peregrino field. This is the first multilateral well in Brazil with gravel pack in both branches. The Peregrino field is located 85 km offshore Brazil in the Campos Basin in about 100 m water depth in licenses BM-C-7 and BM-C-47. Statoil (60%) operates the field, with Sinochem (40%).
