The South Stream Transport consortium has confirmed that Allseas will lay the second 900-km (559-mi) long string of the TurkStream pipeline taking gas from Russian fields across the Black Sea to Turkey. As with the first string, Allseas will deploy its newest construction vesselPioneeringSpirit for the campaign. Work on the first string is due to start later this year: both parallel lines will have throughput capacity of 15.75 bcm/yr.
KBR will perform conceptual studies and front-end engineering services for various fields in the Kazakh sector of the Caspian Sea, under a two-year call-off contract awarded by North Caspian Operating Co. Fields covered include Kashagan, Aktote, Kairan, and Kalamkas. One of KBR’s briefs is to maximize local Kazakh contact for future development projects.
Wood Group has started detailed engineering for the Noble Energy-operated Leviathan platform, to be stationed in 86 m (282 ft) of water 9.6 km (6 mi) offshore Israel.
The 30,000-ton structure will have initial gas production capacity of 1.2 bcf/d: this will be delivered via two 117-km (73-mi) flowlines connected to four subsea wells, to be drilled next year at the deepwater Leviathan field location.
Noble estimates capex costs for the first-phase development - due to come onstream by end-2019 - at $3.75 billion, including pre-investment to allow for subsequent expansion of the platform’s processing capacity to 2.1 bcf/d.
CGG has acquired and processed the first airborne gravity gradiometry over the Kingdom of Bahrain for state oil company Bapco. The 18,000-km (11,184-mi) data-set covers roughly 7,700 sq km (2,973 sq mi) of open offshore exploration acreage, which Bapco and interested bidders can make use of for the Kingdom’s future licensing rounds. CGG and Bapco also plan to combine the new data with existing seismic, well and geological information to help identify areas of prospectivity.
Iraq is reportedly considering starting offshore exploration for oil and gas in its southern territorial waters with the aim of boosting the nation’s reserves.
Iran’s first FPSO, built in Singapore at a cost of $300 million, sailed recently to the South Pars field in the Persian Gulf. The facility, which could start operating by May, is designed to start production from the field’s 7-Bbbl oil layer, located 130 km (81 mi) offshore. Early-phase production should be in the range of 20,000-35,000 b/d.
Fugro has been performing a seabed survey for Shell offshore Kenya designed to detect natural leakage of hydrocarbons. Results will be integrated with a recent offshore seismic survey in the area to address potential future drilling locations.

Frogtech Geoscience’s new basement-focused study of hydrocarbon potential in the Gulf of Thailand and the South China Sea provides insights into the region’s tectonic evaluation. Redefinition of the Paleotethys suture suggests it formed a significant rheological and thermal boundary that influenced evolution of hydrocarbon-rich basin systems. One of Frogtech’s aims was to address the challenge of seismic imaging of deep basin geometries in the South China Sea in particular, where thick sediments and extensive carbonates hamper resolution of structures at depth.
Chevron has paid $2.3 million to secure exploration rights for the next six years to the new WA-526 permit offshore Western Australia. The acreage is in a gas-rich part of the Northern Carnarvon basin, close to the company’s Gorgon and the Pluto LNG projects.
Cooper Energy plans to drill two horizontal wells to develop the Sole gas field in the VIC/RL3 permit in the eastern Gippsland basin, 40 km (25 mi) offshore Victoria in southeast Australia. The company has commissioned Subsea 7 to install subsea facilities taking production to the onshore Orbost gas plant: these include 64 km (40 mi) of pipeline and a similar length umbilical, plus associated spool and manifold. Pending a final investment decision, offshore installations should follow next year. After Sole starts production, Cooper may look to tie in the nearby Manta gas/condensate accumulation.
