ExxonMobil and partners Hess and CNOOC Nexen Petroleum have sanctioned the $3.2-billion first-phase development of the Liza oil field, 200 km (124 mi) offshore Guyana. Following strong results from the latest appraisal well, Liza-4, recoverable reserves across the block now stand at 2-2.5 Bboe. SBM Offshore will supply a leased FPSO - a converted VLCC - to be spread-moored in 1,525 m (5,003 ft) of water, and producing up to 120,000 b/d of oil from 17 wells linked to four subsea drill centers, with associated gas treatment and water injection capability. First oil should follow by 2020.

The Gambia’s government has approved FAR’s assumption of an 80% operated stake in offshore blocks A2 and A5, with current incumbent Erin Energy retaining 20%. FAR will part-carry Erin for the costs of the first exploration well, likely to be drilled in 2018. Both blocks are next to and on trend with the SNE oilfield off Senegal to the north, with large shelf-edge prospects identified from 3D seismic. Water depths range from 50-1,200 m (164-3,937 ft).
NNPC, First Exploration & Production, and Schlumberger have agreed to jointly develop the shallow-water Anyala and Madu fields in the Niger Delta, 40 km (25 mi) offshore Nigeria.

The world’s first converted floating liquefaction vessel should have departed Keppel Shipyard in Singapore for Cameroon. Owner Golar LNG will deploy theHilli Episeyo, formerly a 1975-built Moss LNG carrier, on the Sanagud Sud and Ebome gas fields offshore Kribi for Perenco and state-owned Société Nationale des Hydrocarbures. The converted vessel has storage capacity of 125,000 cu m (4.41 MMcf), with sponsons fitted on both sides of the hull to house liquefaction and gas compression equipment.
Keppel Shipyard is currently converting theM/T Tempera into an FPSO for deployment on Perenco’s Yombe field offshore Republic of Congo, to the south. It will replace the FPSO Conkouati that has operated on Yombe for more than 25 years.
BP is exiting block 24/11 offshore Angola after deciding that its 2014 Katambi gas discovery is not commercial.
Rosneft has discovered oil in the Laptev Sea via the Tsentralno-Olginskaya well, drilled horizontally from the shore of the Khara-Tumus Pensinsula in Khatanga Bay, north of the Karsnoyarsk region. Analysis of core samples taken from subsurface depths of 2,305-2,363 m (7,562-7,752 ft) showed high levels of oil saturation.
Farther to the east in the Sea of Okhostk, the semisubmersibleHakuryu-5 has been drilling the first exploratory well for Gazpromneft Sakhalin on the Ayashky license block. The rig has been winterized with drilling mud used from the outset, along with a system for riser-free sludge disposal, to assist wellbore stability.
Allseas’Pioneering Spirit has started deepwater pipelay for Gazprom’s TurkStream gas lines in the Black Sea: each will have throughput capacity of 15.75 bcm/yr. Allseas’ Audacia has been constructing the shallow-water section near the Russian coast.
Wood Group is performing front-end engineering and design (FEED) for Gastrade for the Alexandroupolis Independent Natural Gas System project offshore Greece. This will feature a floating LNG and regasification (FSRU) vessel, providing a new gas supply source to markets in southeast and central Europe. An investment decision should follow in late-2017.
Greek independent Energean has submitted a field development plan to Israel’s Petroleum Commissioner for the Karish and Tanin gas fields offshore Israel. Development will start with three wells on Karish, linked to an FPSO 90 km (56 mi) offshore, with production capacity of 400 MMcf/d and a dry gas pipeline connecting to the Israeli natural gas system. Estimated capex is $1.3-1.5 billion, with first gas slated for 2020. Six wells should then be drilled on Tanin.
Eni will assume 50% of subsoil use rights for the Isatay block in the Kazakh sector of the Caspian Sea from JSC KazMunayGas. The two companies will jointly operate the block, thought to potentially hold large hydrocarbon resources, and will apply proprietary exploration techniques developed by Eni.
ADES International Holding has a three-month drilling contract for Belayim Petroleum in the Gulf of Suez offshore Egypt, using the jackupADMARINE 88. Another ADES jackup, ADMARINE VIII, contracted to Petrozenima, was due to start a fracking job last month on the North July well in the same region.
Qatar Petroleum (QP) plans to double the size of a new development project on the southern part of the offshore North field, first announced in April, in order to lift Qatar’s LNG production to 100 MM tons/yr. The investment would increase the field’s gas output by 20% to 4 bcf/d.
Total and QP have jointly assumed the reigns of the offshore Al-Shaheen oilfield, 80 km (50 mi) north of Ras Laffan, from previous operator Maersk Oil under their North Oil Company partnership. A new phase of development, due to start this summer, involves drilling 56 wells with two rigs initially, to be joined by a third at the start of next year.
National Iranian Oil Co. (NIOC) and Total have signed a 20-year contract for development and production of Phase 11 of the South Pars gas/condensate development in the Persian Gulf. This was the first signing involving a foreign oil company under the new Iranian Petroleum Contract. Total operates the development, in partnership with CNPC and NIOC subsidiary Petropars.
The first phase, with an estimated cost of around $2 billion, calls for 30 wells and two wellhead platforms connected to existing onshore treatment facilities via two subsea pipelines. Changing reservoir conditions could in time necessitate the addition of 20,000-metric ton (22,046-ton) offshore compression platforms, a first for South Pars, and the largest ever built for the Persian Gulf. Analyst Wood Mackenzie expects Phase 11 to recover more than 10 tcf of sweetened gas and 450 MMbbl of condensate, with potential spin-offs to local Iranian contractors in terms of enhanced engineering capabilities.
Another European major, Eni, has reportedly agreed to perform appraisal studies with NIOC for development of the giant Kish gas/condensate field, discovered in 2006, close to Kish Island in the Persian Gulf.
GE Oil & Gas has agreed to collaborate on development projects in Area 4 off Mozambique with EEA, a joint venture between Eni and CNPC. EEA has a 70% operated stake in the concession in the Rovuma basin. GE will initially supply subsea production systems and associated services for the recently contracted Coral South FLNG vessel, which will have an LNG capacity of around 3.4 MM tons/yr, supplied through six subsea wells. The agreement extends to future upstream projects in Area 4.
Reliance Industries and BP have sanctioned development of the R-Series dry gas fields in block KGD6, 70 km (43 mi) offshore eastern India in water depths of more than 2,000 m (6,562 ft). The partners plan a subsea tieback to the block’s existing control and riser platform. The R-Series (D34) project should produce up to 425 MMcf/d and come onstream in 2020. RIL and BP expect to submit development plans to India’s government for two further projects before year-end: the three combined carry an estimated price tag of $6 billion, and should eventually add 1 bcf/d to the country’s domestic gas production.
ONGC has yet to receive government approval for its takeover of GSPC’s Deen Dayal West field in the same KG basin, according to a recent statement by chairman D.K. Sarraf. Assuming this does come through, the company plans to further develop the field and integrate the facilities with Cluster 1 on block KG-DWN-98/2.
