  • Petroceltic International said that the first of up to 24 new development wells planned in Algeria’s Ain Tsila gas and condensate field was successful. The AT-10 well, situated about 2 miles from the AT-1 field discovery well, reached a total depth of 6,578 ft. Wireline logs indicated that the expected initial offtake rate would be comparable to the AT-1 and AT-8 wells, both of which test-flowed at more than 30 MMcf/D. Petroceltic is the operator with a 38.25% interest in the production-sharing contract that covers the Ain Tsila output. The remaining interests are held by Sonatrach (43.375%) and Enel (18.375%).

  • Sonangol reported that it has found reserves in the Kwanza Basin of Angola that could total 2.2 billion BOE, including reserves in a block jointly owned with BP. Block 24, operated by BP, holds an estimated 280 million bbl of condensate and 8 Tcf of gas, totaling 1.7 billion BOE, Sonangol said in a statement seen by Reuters. Sonangol also said that Block 20, which it operates, is commercially viable and contains an estimated 139 million bbl of condensate and 2.5 Tcf of gas, totaling 570 million BOE.

  • Lekoil said that the Otakikpo-002 well in Nigeria’s Otakikpo Marginal Field has flowed oil from two upper zones during production tests. Peak flow rates of 6,404 B/D and 5,684 B/D were achieved in the two zones, with both test volumes flowing through a 36/64-in. choke. Lekoil holds a 40% interest in the field with operator Green Energy International holding a 60% share.

  • China National Offshore Oil Company (CNOOC) has started production from the Panyu 11-5 oil field in the Pearl River Mouth Basin. Three horizontal wells have been drilled in the field, which also makes use of existing facilities in the Panyu 5-1 field. One well is on production in the new field with an output of about 3,270 B/D. Panyu 11-5 is expected to reach peak production of 3,900 B/D later this year. CNOOC holds a 100% interest in the field.

  • New Zealand Oil & Gas (NZOG) reported a further upgrade in developed reserves in the Kupe gas and light oil field offshore Taranaki, New Zealand, following analysis by the field’s joint venture partners. The upgrade from 5.22 million BOE to 6.02 million BOE is in addition to a 34.7% increase announced in October. Based on detailed reservoir simulation uncertainty modeling, the company is reporting a new 15.29% increase in proved and probable developed reserves. NZOG has a 15% interest in the field, which is operated by Origin Energy (50%). Other participants are Genesis Energy(31%) and Mitsui (4%).

  • Latin America-Caribbean

  • Statoil and partners Repsol Sinopec Brasil and Petrobras have struck oil in the deepwater Campos Basin offshore Brazil. The appraisal well encountered a 175-m hydrocarbon column and produced approximately 16 MMscf/D of gas and 4,000 B/D of oil, Statoil said. Repsol Sinopec Brasil, a joint venture of Repsol and Sinopec, is the current operator. Statoil will take over as operator in the third quarter, raising its 35% stake in the project to 70%. Petrobras holds a 30% stake.

  • Middle East-North Africa

  • Gas Plus Khalakan (GPK) announced that the Shewashan-2 development well will contribute to the 10,000-B/D year-end production target for Phase 1 of the Shewashan oil field in Iraq’s Kurdistan Region. The well was drilled to a 9,081‑ft depth at a cost of USD 19.5 million. During tests, the well flowed at a maximum rate of 4,400 B/D from Cretaceous fractured carbonate reservoirs. The Shewashan-1 well is being recompleted as a deviated producing well. GPK is operator with an 80% interest in the wells.

  • Northern Europe

  • Providence Resources said that the Druid and Drombeg prospects in the southern Porcupine Basin, offshore Ireland, could hold total cumulative in-place unrisked prospective resources of 5 billion bbl of oil. The company, which carried out the prospective resource research in a joint industry project with Schlumberger,revealed that both prospects could be evaluated with a single vertical exploration well, costing an estimated USD 85 million.

  • South Asia-Indian Subcontinent

  • Mari Petroleum has made a third significant discovery in Pakistan’s Karak Block. The Halini-Deep-1 discovery follows successes at the Halini-X-1 well in 2011 and the Kalabagh-1A well last year. The Halini-Deep well was drilled to a depth of 19,357 ft. Drillstem test results showed production from the Samana Suk reservoir, which lies beneath the Lumshiwal, Hangu, and Lockhart reservoirs to which the previous wells are connected. In a completion integrity test, flow rates of 1,425 B/D of oil and 1.18 MMscf/D (197 BOE/D) of gas were achieved from the new well. Mari, the operator, has a 60% interest in the well. MOL holds the remaining interest.

  • USA

  • ExxonMobil has started production at its Point Thomson project, the first project it has operated on Alaska’s North Slope. Initial central pad production of about 5,000 B/D of natural gas condensate and 100 MMscf/D of recycled gas will rise over a few months to peak levels of up to 10,000 B/D of condensate and 200 MMscf/D of recycled gas. The recycled gas is reinjected for future recovery. The Point Thomson reservoir contains an estimated 8 Tcf of gas and associated condensate, which represents 25% of the North Slope’s known gas. ExxonMobil holds a 62% interest in the project, with BP(32%), ConocoPhillips (4.9%), and other parties holding the remainder (1.1%).

  • Otto Energy has provided updated information on the SM-71 # 1 discovery well on South Marsh Island Block 71 in the US Gulf of Mexico. Using the initial results of quad-combo porosity logging, the company has made these preliminary estimates of net true vertical thickness (TVT) oil pay counts for the well: I3 Sand, 17 ft TVT pay; J Sand, 24 ft TVT pay; and D5 Sand, 91 ft TVT pay. The well will be deepened by 600 ft to the original permitted measured depth of 7,452 ft to extend the evaluation of targeted sands. By bearing certain project costs, Otto will earn a 50% interest in the well through a farm-in agreement with operator Byron Energy, which will retain a 50% share.
