India’s ONGC Videsh Ltd. said 32 wells are planned for a phased expansion of the Sakhalin I Odoptu development in Russia.

Extended-reach drilling from onshore to offshore in Odoptu Stage 2 is planned for two sites 9 km apart: the North Wellsite and the South Wellsite.

ONGC Videsh said the Krechet land rig, a new drilling rig, spudded its first well Feb. 28 after completing conductor driving for the first four wells. The company expects to reach measured depths of 13,300 m, along with total vertical depths of 2,000 m. The rig was fabricated in the Keppel AmFELS yard in Brownsville, Tex. Modules were shipped on five barges into the Sea of Okhotsk and Piltun Bay in the northeastern part of Sakhalin Island.

The fully enclosed drilling rig and pipe barn allow the rig crew to perform drilling operations in temperatures of 21° C. yearround.

The Odoptu Stage 2 development is expected to start production in the third quarter. The field is expected to reach its peak production of 65,000 b/d in 2018.

Odoptu Stage 1 oil and natural gas production began in 2010 (OGJ Online, Sept. 29, 2010).

Operator Exxon Neftegas Ltd. has 30% as does Sodeco. ONGC Videsh and Rosneft each have 20%.
