  • Tullow Oil announced in mid-August that first oil has flowed from the Tweneboa, Enyenra, and Ntomme (TEN) fields offshore Ghana, which was on time and on budget for the project’s development plan approved by the government in May 2013. The company expects oil output to ramp up gradually through the rest of the year toward a production facility capacity of 80,000 B/D. Tullow is the operator of the TEN fields with a 47.18% stake. Its joint-venture partners are Anadarko (17%), Kosmos Energy (17%), Ghana National Petroleum Corporation (15%), and PetroSA (3.82%).

  • Rosneft has made a discovery at the PLDD well in the Wild Orchid gas condensate field in Block 06.1 of the Nam Con Son Basin offshore Vietnam. The discovery is being evaluated for the volume of reserves and commercial attractiveness, and there is a potential synergy with the nearby Rosneft-operated Lan Tay production platform, the company said. Rosneft is the operator and holds a 35% interest in Block 06.1, with the remaining interests held by Petrovietnam(20%) and ONGC (45%).

  • Beach Energy completed logging at the Callawonga-12 oil development well in Petroleum Production License 220 on the western flank of South Australia’s Cooper Basin. The well was being cased and suspended after reaching a total depth of 4,754 ft in the Westbourne formation. The presence of a gross oil column of 13 ft, or a net column of 6.6 ft, was interpreted in the primary target, the McKinlay member and the Namur sandstone. The company operates and holds a 75% interest in the license, with the remaining stake held by Cooper Energy.

  • Andes Energia announced discoveries in the Chachahuen Block in Mendoza Province, Argentina. About 20 ft of net oil pay was discovered by exploration well Cerro Redondo x-1 in the Rayoso formation sandstone, and gas was found by exploration well La Orilla x-1 in the deeper horizon of the Lotena formation. Gas was also found by exploration well Remanso del Colorado x-1 in the deeper horizon of the Cuyo Group. The discoveries reaffirm “the large-scale potential of Chachahuen,” said company Chairman Nicolas Mallo Huergo. Andes Energia is developing the block in a joint venture with YPF and Energia Mendocina.

  • Tethys Oil is maintaining its increased level of oil production in Oman, where it produces from onshore blocks 3 and 4. A second-quarter net output of 1.096 million bbl followed a nearly identical net total of 1.101 million bbl produced during the first quarter. Production in both periods exceeded a net output of 997,904 bbl during the fourth quarter of last year. Tethys is one of the largest onshore oil concession holders in the Sultanate of Oman with a current net production of about 12,000 B/D.

  • Gas Plus Khalakan (GPK) reported that the No. 1 sidetrack well in the Shewashan field of the Kurdistan Region of Iraq was successfully drilled and recompleted recently as a horizontal producer in the Qamchuga formation. The well is producing from 500 B/D to 700 B/D of oil, although it may require further stimulation to meet predrill production estimates that were based upon the original Shewashan-1 vertical well. The company expects total production at the Shewashan development to hit 10,000 B/D early next year. GPK is the operator with an 80% interest in the development.

  • Premier Oil has discovered oil at the Bagpuss 13/25-1 well on the Halibut Horst in the Outer Moray Firth of the United Kingdom North Sea. The well encountered 41 ft of hydrocarbon-bearing sands within a 68-ft hydrocarbon column, which was in line with predrill estimates, and reached a total depth of 1,532 ft. Hydrocarbon and reservoir analysis are under way to determine whether the discovery is commercial. The joint-venture partners in the Bagpuss prospect are operator Premier, with a 37.5% interest, Maersk (25%), EnCounter Oil (15%), North Sea Energy (15%), and Groliffe (7.5%).

  • Statoil has started oil and gas production from the Fram C East well offshore Norway. The well was drilled from the Fram subsea template, and production is being tied back to the Troll C hub in the North Sea. The company said that project capital cost had been reduced to USD 73 million from an originally estimated USD 97 million as a result of “a simple, smart well concept and significantly increased drilling efficiency.” Statoil, the operator, holds a 45% interest in the well, with ExxonMobil (25%), Engie (15%), and Idemitsu (15%) holding the remaining interests.

  • South Asia-Indian Subcontinent

  • Oil & Gas Development Company (OGDC) has successfully tested and completed the X-6 and X-7 development wells in the Nashpa field in the Karak and Kohat district of Pakistan’s KPK Province. The Nashpa X-7 well, drilled to a 15,079‑ft depth, produced 2,700 B/D of oil and 7.4 MMscf/D of gas through a 36/64‑in. choke at wellhead flowing pressure of 1,886 psig. The Nashpa X-6 well, drilled to a 16,486‑ft depth, produced 2,550 B/D of oil and 16.3 MMscf/D of gas through a 36/64‑in. choke at wellhead flowing pressure of 2,667 psig. OGDC is the operator with a 56.45% interest in the field. Pakistan Petroleum (28.55%) and Government Holdings (15%) have the remaining interests.

  • Jura Energy reported a gas discovery at the Khamiso-1 exploration well in Pakistan’s Guddu Block. The well was drilled to a total depth of 2,470 ft in an Eocene limestone of the Pirkoh formation. During a short-duration prestimulation test conducted on a 32/64‑in. choke, the well encountered an average gas flow of 2.95 MMcf/D. Jura holds a 13.5% interest in the block, which is operated by OGDC.

  • Anadarko has drilled a successful appraisal well at the Shenandoah field in Walker Ridge Block 51 of the US Gulf of Mexico. Drilled in 5,900 ft of water to a total depth of 31,100 ft, the Shenandoah No. 5 well encountered more than 1,000 net ft of high-quality oil pay in the Lower Tertiary Wilcox sands. The well’s results indicate an extension of the field reservoir boundaries to the east. Anadarko, the operator, holds a 33% interest in the field, with other interests held by ConocoPhillips (30%), Cobalt International Energy (20%), and Venari Resources (17%).
