  • Panoro Energy announced an oil discovery in the Ruche North East Marin-1 well offshore Gabon. The 1 well was drilled to identify additional oil resources in the presalt Gamba and Dentale Formations in the greater Ruche Area, and completed within budget. These resources may be developed together in the future with the existing Ruche field discoveries made by Panoro in 2011 and located 3 km to the southwest. Drilled with the Borr Norve jackup unit in 115-m water depth, the well reached a vertical depth of 3400 m within the Dentale Formation. Log evaluation, pressure data, and fluid samples indicate that approximately 15 m of good-quality oil pay was encountered in the Gamba Formation and 25 m of oil pay in stacked reservoirs within the Dentale Formation. The forward plan includes a sidetrack that will appraise the Dentale sands in an updip location and the lateral extent of the Gamba reservoir.

  • Carnarvon Petroleum announced that the Quadrant Energy-operated Dorado-1 well offshore Western Australia has encountered more oil. The well on the WA-437-P permit recovered light oil from the Crespin Member containing 50 m gross hydrocarbons and with a net oil pay thickness of 22 m. Quality of the reservoir was above predrill estimates with average porosities of 14%. Analysis of pressure data confirmed that the Dorado structure contains oil columns in the Caley, Crespin, and Milne Members and a gas and condensate column in the Baxter Member, aggregating to total net hydrocarbon pay of 132 m. There was no sign of water in the Caley, Baxter, and Milne sands, although the lower section of the Crespin sand does contain an interpreted water contact.

  • Eni announced a gas discovery in the Egyptian Western Desert. The well was drilled on the Faramid South exploration prospect in the East Obayed Concession, 18.6 miles northwest of the Melehia Concession, and reached a target depth of 17,000 ft. The discovery well has been open to production delivering 25 million scf/D, confirming the East Obayed Concession’s potential, the company said. Eni has begun studies to develop gas reserves that can contribute to increasing Egypt’s gas production from the Western Desert Basin. Through its operating company AGIBA, Eni currently produces 55,000 BOE/D from the Egyptian Western Desert. AGIBA owns 100% of the East Obayed Concession.

  • Siccar Point Energy has concluded well-testing operations on the 204/10a-5 appraisal well in the Cambo field, northwest of Shetland. A vertical pilot hole was initially drilled, confirming over 100 ft of oil column and a higher-than-anticipated net pay of 58 ft. Extensive logging and coring were conducted, confirming a high-quality multi-Darcy reservoir with petrophysical properties better than anticipated. A 1,612‑ft horizontal section was then drilled to conduct an extended well test. Following initial well-cleanup operations, the well was successfully tested on natural flow for 10 days. Initial results indicate excellent reservoir productivity and sustained flow. The results of the well will be incorporated into the Cambo field development plan and the well suspended for use as a future development well. Earlier in 2018, Siccar’s partner Shell acquired a 30% nonoperated working interest in UK Continental Shelf licenses P1028 and P1189 (incorporating the Cambo discovery) and a 22.5% nonoperated working interest in P1830.

  • M2 Subsea has completed a contract with Ithaca Energy UK to conduct a subsea system survey of a North Sea field. The company deployed the Go Electra multiservice vessel equipped with a Triton XLX work-class remotely operated vehicle to the Stella field, located 280 km off Aberdeen in a water depth of 85 m. The Ithaca-operated Greater Stella Area is located in the heart of the Central Graben on the UK Continental Shelf, surrounded by various large producing fields and numerous undeveloped discoveries. The scope of work included the survey and inspection of subsea systems including pipelines and subsea structures. M2 Subsea previously completed a project for Ithaca Energy in 2017.

  • A consortium led by the Oil and Natural Gas Company (ONGC) of India is pursuing hydrocarbon leads in the shallow waters of the MB-OSN-2005/1 Block, located in the Mumbai Offshore Basin near Saurashtra, after two exploration wells hit oil and gas. A plan calls for drilling four more wells in the north and northeastern parts of the concession to assess the quantity of extractable oil and gas reserves. The second-phase exploration project is estimated to cost approximately $40 million. The operator identified the drilling locations on the basis of detailed interpretation of 3D seismic data. The wells will be drilled to a target depth of between 2600 and 3000 m in a water depth ranging from 17 to 37 m.

  • Four LLOG Exploration-operated discoveries (six wells) in the deepwater Gulf of Mexico are under development and are expected to be placed on production in 2018. The LaFemme, Blue Wing Olive, and the Red Zinger wells are being tied back to the LLOG-operated Delta House facility in Mississippi Canyon Block 254. LLOG’s partners in LaFemme and Blue Wing Olive are Beacon Offshore Energy Operating, Red Willow Offshore, Ridgewood Energy, and Houston Energy. The company’s partners in Red Zinger are Beacon Offshore Energy Operating, Red Willow Offshore, and Ridgewood Energy. The Claiborne prospect in Mississippi Canyon Block 794 had a discovery well drilled in 2015 and was successfully appraised with a second well in late 2016. Both wells are being tied back to the Walter-operated Coelacanth platform in Ewing Bank Block 834. LLOG’s partners in Claiborne are Ridgewood Energy, Red Willow Offshore, CL&F Offshore, and Beacon Offshore Energy Operating.

  • The Rowan jackup Ralph Coffman has spudded the Canoe exploration well in the Vermilion Area, South Addition Block 378 in the Gulf of Mexico for operator GulfSlope Energy. The well is located in 325 ft of water. Drilling is expected to take approximately 15 days to reach a measured depth of 6,249 ft and will test multiple above-salt Pleistocene age amplitudes that correlate to productive zones in nearby producing fields. After Canoe, GulfSlope will mobilize the jackup to drill the initial exploration well on the Tau prospect on Ship Shoal Area, South Addition Blocks 336/351. The Tau well is in 305 ft of water and is planned to be drilled to a measured depth of 29,728 ft. The well will target multiple deep subsalt formations.
