OGX, Brazil’s leading privately-owned oil company, has strengthened its track record with a potentially major discovery in the Campos Basin. Well 1-OGX-1-RJS, drilled by theOcean Ambassador on block BM C-43 in 140 m (459 ft) of water, encountered an oil column of over 200 m (656 ft) and net pay of 57 m (187 ft). Based on the well data and 3D seismic interpretation, OGX estimates recoverable volumes between 500 MMbbl and 1.5 billion bbl.

General Executive Officer Paulo Mendonca says: “These results highlight the high petrolific potential of our blocks and contribute to the reduction of exploratory risk on our upcoming prospects to be drilled in the region.” TheOcean Ambassador has since mobilized to block BM-C-41 to drill a shallow water well in the southern part of the Campos basin.

Houston-based Noble Energy has contracted DOF Subsea UK for offshore studies relating to its Dalit and Tamar field developments in Israel’s sector of the Levantine basin. DOF was due to start the program of hydrographic, geophysical, and geotechnical surveys this fall using its own vessel, an AUV, and a third-party geotechnical spread.

Caspian Sea

J. Ray McDermott has completed installation of offshore facilities for Lukoil-Nizhnevolzhskneft on the Yuri Korchagin. This is Lukoil’s first field development in the Russian sector of the Caspian Sea. The scheme comprises an ice-resistant processing platform (LSP-1) bridge-linked to a living quarter platform, with oil offloaded from an FSO to a single-point mooring (SPM) via a 36-mi (58-km), 12-in. (30.5-cm) pipeline. J.Ray transported and installed the 14 foundation piles for LSP-1, the 1,005-ton (912-metric ton) SPM substructure and associated five foundation piles, and the SPM deck. In 2008 J. Ray installed the pipeline under a separate contract from Lukoil.

Yuri Korchagin’s main offshore facilities include an ice-resistant platform bridge-linked to a living-quarters installation.

Total has signed a Heads of Agreement with KazMunaiGas (KMG) for development of the Khvalynskoye gas/condensate field in the Kazhak offshore sector, in shallow water close to the maritime border with Russia. If approved, Total and GdF-Suez will take half KMG’s existing 50% interest in the project, which is operated by Lukoil.

Black Sea

Petrom has brought onstream two new satellite field developments in the Romanian offshore sector via its Platform 7. Output from the Delta field should ramp up to 3,400 boe/d by the end of this year, while Lebada Vest has produced at an initial rate of 900 boe/d.

In the Turkish sector, TPAO has been drilling the Bati Ayazli prospect in the South Akcakoca basin using the GSP jackupSaturn. The well was designed to target two stratigraphic levels, the deeper of which has not been tested in this region before. If the shallower target results in a gas find, this would likely be developed through the Ayazli production complex to the east.

On the eastern side of the Black Sea, Gazprom has begun installing the new Dzhuba-Lazarevskoye-Sochi gas pipeline that will include a 159.5-km (99-mi) offshore section close to the Russian coast.

Bay of Bengal

Bangladesh has filed arbitration actions against Myanmar and India over maritime borders in the Bay of Bengal. The actions were brought under the UN’s Convention on the Law of the Sea (UNCLOS), to which all three countries are signatories. According to Foley Hoag LLP in Washington, which is advising Bangladesh’s government, the claims of Myanmar and India over overlapping waters have prevented Bangladesh from exploiting potentially large deposits of oil and gas off its coast.

The advisers add that license holders such as ConocoPhillips and Tullow Oil have been intimidated by Myanmar warships in waters that Bangladesh claims as its own. Furthermore, Bangladesh complains that Myanmar has granted concessions which have led to drilling or exploration in disputed areas without its consent. India is accused of denying Bangladesh any portion of its continental shelf beyond 200 nautical miles, against the rules and principles established by UNCLOS.

Asia-Pacific

Bongkot joint venture partners PTTEP, Total, and BG Group have signed a gas sales agreement covering all output from the Greater Bongkot South (GBS) field in the Gulf of Thailand. GBS, in blocks B16 and B17, 200 km (124 mi) east of Songkhla, will produce through 13 wellhead platforms linked to a central processing installation. The latter will have capacity to handle 350 MMcf/d of gas and 15,000 b/d of condensate.

Gas will be sent through a new spur line to the PTT 3rd trunk line, with condensate exported to the existing FSO at the Greater Bongkot North field, 80 km (49.7 mi) to the north. GBS should come onstream in 2012.

Also in the Gulf of Thailand, Coastal Energy has contracted EOC for a heavy-lift barge to install fixed platforms early next year at its Bua Ban field on block G5/43. This should facilitate development drilling during the rest of the year.
