This is the fifth exploration well successfully drilled in the area, increasing total potential of Area 4 discoveries, now estimated at 70 Tcf of gas in place. Eni (70%) is operator with GalpEnergia (10%), KOGAS (10%), and ENH (10%, carried through the exploration phase).
  • The Kabelijou-1 well, being drilled by the Ocean Rig Poseidon ultradeepwater drillship, was spudded. The well is located in the Orange basin in Southern Block 2714A in the Nimrod prospect around 50 miles offshore Namibia in about 1,180 ft of water. Petrobras Oil & Gas (30%) is operator, with Chariot Oil & Gas (25%) and BP Exploration (Namibia) (45%).

Asia

  • Lundin Petroleum spudded the second well in its 2012 Malaysian drilling campaign, with the Berangan 1 exploration well in Block SB303, offshore Sabah, Malaysia. A vertical well will be drilled to a depth of 5,577 ft in about 230 ft of water. Targeted hydrocarbons are in mid-Miocene-aged sands in a faulted anticline in an undrilled subbasin 6 miles to the southeast of the Tarap gas discovery. Lundin’s subsidiary Lundin Malaysia BV (75%) is operator, with Petronas Carigali (25%).

Australia

  • Following kickoff of a 12-well drilling program, known as Petroleum Exploration License (PEL) 91, sited on the western margin of the Cooper-Eromanga basin in South Australia, the Baurer-5 well encountered oil, thus extending the Bauer oil field. Bauer-5 encountered 20 ft of net oil pay in the primary Namur target, and 48.3°API light, sweet crude was encountered in the secondary Birkhead target. Bauer-7 was spudded to appraise the Birkhead prospect. Beach (40%) operates PEL 91, with Drillsearch (60%).
  • Chevron made a natural gas discovery in the Gorgon area, about 40 miles northwest of Barrow Island, off the coast of Western Australia. The well was drilled in 690 ft of water to a total depth of 16,581 ft and encountered about 97 ft of net gas pay. Chevron Australia (47.3%) is operator, with ExxonMobil (25%) and Shell Development Australia (25%).

Europe

  • The Cooper well, situated on Block 6506/11 in the Norwegian sector of the North Sea, has encountered hydrocarbons. The well, drilled by the West Alpha mid-water semisubmersible rig, made the discovery in the Middle Jurassic Garn formation at a depth of 17,500 ft. Centrica Resources (40%) is operator, with Faroe (30%) and Suncor Energy (30%)
  • Permission was granted by the North York Moors National Park Authority for the exploratory Westerdale-2 well in onshore Petroleum Exploration and Production License PEDL068, near the village of Westerdale, England, UK. The well is planned to evaluate the Ralph Cross/Westerdale gas discovery in an area updip of the Ralph Cross-1 well. Egdon Resources UK (40%) is operator, with Sterling Resources (UK) (47%), Yorkshire Exploration (8%), and Montrose Industries (5%).
  • The 48/1a-6 well, known as the Platypus gas appraisal well, located in the southern North Sea, recorded a test flow rate of 27 MMscf/D on a 96/65-in. choke. Mid-June, the well had reached a total measured depth of 14,175 ft, including a 3,100-ft horizontal section. A drillstem test was successfully completed late July, and the well is being suspended for use as a future production well. Dana Petroleum (59%) is operator, with The Parkmead Group (15%), First Oil Expro (11%), and CalEnergy Gas (15%).

Middle East

  • The Gulak-1 exploration well was spudded, the fourth exploration well to be drilled on the Akri-Bijeel block in the Kurdistan Region of Iraq. It is the first exploration well to target the Gulak anticline at the extreme eastern end of the block. Gulak-1 will target prospective intervals in the Jurassic and Triassic formations, drilling to a planned depth of about 12,000 ft in the Triassic Kurra Chine formation. Kalegran, a 100% subsidiary of MOL Hungarian Oil and Gas, is operator, with an 80% interest; Gulf Keystone holds the remaining 20%.

North America

  • An oil discovery was made at the Danny II exploration well at the Bushwood field, located in Garden Banks Block 506, about 145 miles offshore Galveston, Texas. Drilled to a total depth of about 14,750 ft in water depths of about 2,800 ft, Danny II encountered more than 70 ft of high-quality net pay. Deep Gulf Energy LP (operator) and Deep Gulf Energy II LLC hold a 50% working interest, with Helix Energy Solutions Group (50%).
  • Workover work has been completed at the Mississippi Canyon Block 941 A-2 well, located in the Mirage field at the Telemark Hub in the central US Gulf of Mexico. The well was completed with 3½-in. tubing at a measured depth of 17,140 to 17,401 ft, to add the Miocene B Sand completion to the wellbore for field development optimization. The well produces through the ATP Titan floating, drilling, and production platform. ATP (100%) operates the ATP Titan and Telemark Hub.
  • The Payne #1H well, targeting the Woodbine formation and drilled to a total measured depth of 16,130 ft, including a 7,460-ft lateral, was completed using a 26-stage fracture stimulation. Located in Crimson Exploration’s Force Area in Madison County, Texas, the well tested at a gross initial production rate of 1,332 BOE/D, or 1,128 bbl of oil, 112 bbl of natural gas liquids, and 665 Mcf of natural gas. Crimson (92.1%) is operator.

South America

  • The Jaguar-1 high-pressure, high-temperature well, located on the Georgetown Petroleum Prospecting License  in the Guyana-Suriname basin, was plugged at a depth of 4876 m without reaching the primary objective in the Late Cretaceous geologic zone. Despite this, samples of light oil were successfully recovered from two Late Cretaceous turbidite sands. Repsol Exploración (15%) is operator, with YPF Guyana (30%), Tullow Oil (30%), and CGX Resources (25%).
