MODEC has contracted Keppel FELS to fabricate and integrate the topsides for the FPSO Carioca MV30 that will serve Petrobras’ Sepia field development in the presalt Santos basin, 250 km (155 mi) off the coast of Rio de Janeiro. The BrasFELS shipyard in Angra dos Reis in the Rio area will start construction of the modules shortly. The completed vessel will be able to process 180,000 b/d of oil and 212 MMcf/d of gas, and to store 1.4 MMbbl.

Petrobras has submitted declarations of commerciality for oilfields close to the ultra-deepwater Sapinhoá field in the presalt Santos basin. The company and partners Shell and Repsol Sinopec were awarded the Entorno de Sapinhoá area last year under Brazil’s 2nd bid round. It has suggested names for three new fields in this area, and all should be unitized with the Sapinhoá field, 300 km (186 mi) offshore following definition of a corresponding production individualization agreement. Two floaters currently produce 250,000 b/d from Sapinhoá.

West Africa

Mauritania’s government has awarded Shell two production-sharing contracts for offshore blocks C-10 and C-19, marking the company’s entry into the West African Atlantic margin exploration basin. The concessions cover 23,765 sq km (9,140 sq mi) in water depths ranging from 20-2,000 m (65-6,561 ft). Shell also offered a 10-20% future back-in right to Chariot Oil & Gas for C-10, which the London-based independent originally analyzed before relinquishing the block in 2016.

Total has started producing oil through the first floater for the deepwater Kaombo project in block 32 off Angola, 260 km (161 mi) from Luanda. Kaombo Norte is the first of two converted VLCCs, both designed to produce around 115,000 b/d; Kaombo Sul should enter service in 2019. The project, which should eventually provide 15% of Angola’s oil production, is targeting 650 MMbbl from the Gengibre, Gindungo, Caril, Canela, Mostarda, and Louro fields.

GSP Offshore’s jackup GSP Jupiter should have started drilling for Energean’s Epsilon field development in the Aegean Sea offshore western Greece, following installation of the permanent drilling template. Three wells are due to be drilled from the new minimal facility Lamda platform, 4 km (2.5 mi) west of the producing Prinos complex, with three inter-connecting pipelines to the Prinos Delta platform.

Caspian Sea

Lukoil has committed to develop the Rakushechnoye field, discovered in 2001, 100 km (62 mi) from the Russian northwest Caspian coast. Facilities, to be built by yards in the Astrakhan region, will include a fixed offshore ice-resistant platform, crossover bridge, and subsea interfield lines and cables for connection to the second ice-reinforced platform at the V. Filanovsky field 8.5 km (5.3 mi) distant. All production from Rakushechnoye – due to peak at 1.2 MM metric tons/yr (1.32 MM tons/yr) – will head to the Filanovsky field center for treatment and onward export through existing pipelines.

In addition, Lukoil has installed the substructure for the new wellhead platform for Filanovsky’s third development phase, focused on the western part of the reservoir, with production due to be sent to the first-phase central processing platform. Lukoil-Nizhnevolzhskneft is constructing the new platform’s topsides.

ONGC had to call in India’s Navy earlier this summer to help plug a gas leak from an unmanned platform in Mumbai High South complex in the Arabian Sea, 180 km (112 mi) offshore western India. After identifying the leak, the platform crew acted immediately to shut down operations, but rough weather prevented a response team from flying in the normal way to land on the deck. The Navy obliged by dispatching a Sea King N555 helicopter which winched the four-strong team onto the platform to conduct the repairs.

Woodside Energy has discovered gas with the Aung Siddhi-1 exploration well offshore Myanmar. The well encountered pay in both the upper and lower main targets, with the gas columns later confirmed through pressure measurements.

Australasia

First gas has flowed from INPEX’ Ichthys LNG project offshore/onshore northwest Australia, with the first well coming onstream following the completion of final safety checks. Produced gas and condensate from the subsea wells in 260 m (853 ft) water depth are directed to the field’s central processing facility Ichthys Explorer for separation. Gas is transported through an 890-km (553-mi) export line to the two-train onshore liquefaction plant in Darwin, while the liquids travel through a short pipeline to the FPSO Ichthys Venturer for subsequent offloading to tankers. At peak the offshore facilities will deliver 1.6 MMcf/d of gas and 85,000 b/d of condensate.
