Gazprom Neft completes offshore seismic surveying in the Kara Sea

Gazprom Neft has completed seismic works at the Yuzhno-Obsky license block, located in the waters of the Gulf of Ob in the Kara Sea - the objective of investigations at this Gazprom Neft offshore asset being to clarify the structure of promising underlying geological features.

Seismic surveying involved six specialist vessels, equipped to work at ultra-shallow depths of less than seven metres. Optimum planning meant field investigations completed in just one short season. Some 410 km2 of the license block was covered under 3D seismic surveying, with a further 115 kilometres of 2D seismic surveying being undertaken in the surrounding waters of the license block.

A plan for further geological prospecting works will be put together based on the seismic-survey data obtained, including exploratory-drilling zones. Going forward, the block will form part of Gazprom Neft's major industrial cluster in the south of the Yamal Peninsula. The company is considering the possibility of developing this asset by utilising infrastructure at its Novoportovskoye field, located near to the Yuzhno-Obsky license block.

"Assuming geological prospecting is successful, the Yuzhno-Obsky license block's resource base is going to make a major contribution to the development of the Arctic transport system. We're talking here about both long-term utilisation of company facilities (the unique Arctic Gates oil-transhipment terminal, and the gas pipeline through the Gulf of Ob, which connects the south of the Yamal Peninsula with the Unified Gas Supply System) and, more generally, increasing freight traffic along Russia's major strategic logistics corridor - the Northern Sea Route."
