Norway’s Shearwater GeoServices has been contracted to acquire two 3D seismic surveys offshore South Korea, together with seismic data processing and imaging, for Korea National Oil Corporation (KNOC).

The Myungtae 3D survey to be acquired on block Block 6-1 Central & East will cover approximately 2575 square kilometres.

Shearwater said the data would be processed through a full time and depth imaging sequence, with delivery of predicted reservoir properties.

The second survey covers approximately 500 square kilometres and with data being processed through a full-time processing sequence.

Shearwater will use the survey vessel Geo Coral to acquire the two shoots. The surveys are expected to take approximately four months to complete during the northern hemisphere summer of 2022.

The Geo Coral is a high-capacity seismic vessel, capable of multicomponent acquisition, and has been operating throughout the Asia Pacific region for the past two years.

The contract is the first KNOC has awarded to Shearwater and includes reservoir properties prediction analysis following processing.

It will be the company’s first reservoir characterisation project in partnership with Qeye, reflecting a complete workflow from geophysical data collection through to geoscience deliverables.

“By delivering the full sequence of geophysical services, from acquisition through to final subsurface property prediction, we support our clients’ ambitions to shorten project timelines, increase technical assurance and generate additional value,” said Shearwater chief executive Irene Waage Basili.

“We look forward to working with KNOC in a new geographical market, and to deliver high-quality seismic data and reservoir characterisations.”

South Korea sees limited upstream action, making KNOC’s operations in offshore Block 6-1 all that more interesting.
