Africa (Sub-Sahara) Marathon Oil has produced first gas from its Alba B3 compression platform offshore Equatorial Guinea. The startup enables the company to convert approximately 130 million BOE of proved undeveloped reserves, which more than doubles its remaining proved developed reserve base in the country. Marathon holds an operating interest of about 65% in the field, with Noble Energy holding the remaining stake. Aminex said that gas production from the Kiliwani North-1 well in Tanzania has reached 30 MMcf/D (about 5,000 BOE/D). The project's commissioning process is expected to conclude with a well test to determine the optimal production rate, which previous test data suggest will be approximately 30 MMcf/D, the company said. The operator of the Kiliwani North Development License, Aminex holds a 54.575% interest in the well. Asia Pacific Beach Energy produced first gas from the Udacha field in Production Retention License 26 of the Cooper Basin in South Australia.
Africa (Sub-Sahara) 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%). Asia Pacific 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.
Africa (Sub-Sahara) ExxonMobil will drill its first exploratory well offshore Liberia this month, the company announced on 18 October. A deepwater well is planned on the Liberia-13 Block, which is about 50 miles off the coast of the West African country. Liberia has no oil production at present. Solo Oil plans to spud the Ntorya-2 appraisal well in Tanzania next month. The drilling pad is a mile southwest of the 2012 Ntorya-1 discovery well, which was tested at rates of 20.1 MMcf/D of gas and 139 B/D of condensate. An independent report estimated the discovery to hold 153 Bcf of gas in place, of which 70 Bcf is considered a gross best-estimate contingent resource. A gross best estimate of more than 1 Tcf of gas in place has been made for the Ntorya prospect as a whole, in which the company has a 25% interest.
Africa (Sub-Sahara) San Leon Energy reported encouraging performance from its OML 18 field in Nigeria. Reperforation of an oil well increased gross field production to approximately 61,000 B/D before output was temporarily scaled back to 53,000 B/D for a shut-in, upgrade, and workover of the well. A number of other field wells will be reperforated in coming months, the company said. San Leon holds a 9.72% interest in the field, which is operated by Eroton (35%). Nigerian National Petroleum Corp. holds the remaining stake. FAR said that drilling has begun on the SNE-5 appraisal well offshore Senegal. The well and the following SNE-6 well will evaluate the upper SNE reservoir units' connectivity and deliverability by oil flow testing that will include interference tests.
Genel Energy said that one of its wells drilled to appraise the northern end of the Taq Taq oil field in the Kurdistan region of Iraq encountered oil-bearing reservoirs. The main objective of the well, which had been drilled since February, was to reduce uncertainty about the free water level in the field's north flank. Further development of the Cretaceous reservoir had been deferred pending the test program results. The company said the well, which was drilled to a measured depth of 10,171 ft, encountered good quality Cretaceous Shiranish and Kometan reservoirs but that it was too early to estimate the impact of the results on reserves, production, or future investment. The field now produces a gross 15,100 B/D of oil.
Africa (Sub-Sahara) Eni announced an oil discovery in Block 15/06 offshore Angola in the Kalimba exploration prospect that is estimated to contain between 230 and 300 million bbl of light oil in place. The Kalimba-1 NFW well, which led to the discovery, is located approximately 150 km off the coast. The well was drilled in a depth of 458 m and reached a total depth of 1901 m. The data acquired in the well indicate a production capacity in excess of 5,000 B/D. The discovery creates opportunities for exploration in the southern part of Block 15/06, so far considered mainly gas-prone. The joint venture, with stakes held by Eni (operator, 36.8421%), Sonangol (36.8421%), and SSI Fifteen Limited (26.3158%), will work to appraise the updip of the discovery and will begin studies to fast-track its development.
Norwegian operator DNO announced a two-thirds increase in production from the Peshkabir field in the Tawke license in the Kurdistan region of Iraq to 25,000 BOPD following completion of the Peshkabir-4 well-testing program. The well has been placed on production at a rate of 10,000 BOPD through temporary, capacity-constrained test facilities, with the oil being trucked to Fish Khabur for export. The Peshkabir-4 well was designed as a high-angle well to assess the central part of the structure 4 km west of the Peshkabir-3 well and drilled to a measured depth of 3525 m, including an 1150-m extended-reach reservoir section. A total of 11 zones were tested and flowed between 1,500 and 7,000 BOPD per zone. DNO operates and has a 75% interest in the Tawke license, which contains the Tawke and Peshkabir fields, with partner Genel Energy holding the remaining 25%.
Asia Pacific Santos discovered gas with the Corvus-2 well in the Carnarvon Basin, offshore Western Australia. The well, located in permit WA-45-R, in which Santos has a 100% interest, reached a total depth of 3998 m. It intersected a gross interval of 638 m, one of the largest columns discovered across the North West Shelf. Wireline logging to date has confirmed 245 m of net hydrocarbon pay across the target reservoirs. Total SA and partners ExxonMobil and Oil Search have signed a gas agreement with the government of Papua New Guinea that defines the fiscal framework for the Papua LNG project in the country's Eastern Highlands. The plan involves construction of three 2.7-mtpa LNG trains on the existing PNG-LNG plant site at Caution Bay just west of Port Moresby. Total has 31.1% interest, ExxonMobil has 28.3% interest, and Oil Search has 17.7%.
TechnipFMC and McPhy signed a memorandum of understanding (MoU) to jointly work on the development and project implementation of hydrogen technology. Separately, McPhy and Chart Industries also signed an MoU to scale up hydrogen projects across various markets. Shell's CEO said the Dutch supermajor has "too many layers" and that the move to downsize will help ensure its future. As a result, at least 9,000 people are expected to leave the oil and gas producer between now and 2022. The companies say they will expand their existing technology collaboration to create and deliver solutions to help customers, suppliers, and other businesses lower emissions. Royal Dutch Shell is looking to slash up to 40% off the cost of producing oil and gas in a major drive to save cash so it can overhaul its business and focus more on renewable energy and power markets, sources told Reuters. Phase 1 involved a feasibility study for a facility capable of capturing 750,000 tonnes of carbon dioxide annually. The next phase will explore building a facility capable of more than twice that amount.
The complete paper reviews the results of gas hydrate engineering and production testing studies associated with northern Canada and Alaska. The complete paper describes the hurdles that have prevented single-trip installation of upper and lower completions in the complex world of subsea and deepwater applications and examines the processes, technologies, and risk-mitigation steps that took a concept from pilot to successful deployment. About 16% of US offshore production in the Gulf of Mexico remains offline after Hurricane Laura caused mass evacuations more than a week ago. Based on the early results from mass shut-ins of shale wells, it did not harm long-term production and it paid a short-term dividend with more oil flowing in the days after restarting.
