Viridien to image/re-image 3D seismic data offshore Guyana, India

The offshore eastern India project will address the complexities of thermogenic plays, while the shallow-water Guyana program will support future licensing.

Viridien has committed to two new 3D initiatives offshore India and Guyana.

Exploration for India’s offshore basins

One is a regional multi-client data program for various basins offshore India, designed to support data-driven exploration by operators. It starts with the Phase 1 Mahanadi Basin offshore India’s east coast, which involves reimaging and merging of about 9,000 sq km of 3D seismic data.

Fast-track results should be issued by June, followed by final data around the end of the year.

Viridien said Phase 1 should deliver improved imaging over proven petroleum system areas and deeper water regions. Here, exploration of new thermogenic plays has been problematic due to low-quality imaging of legacy data.

Solutions will include use of modern imaging technologies such as time-lag full-waveform inversion (TLFWI) and least-squares PSDM (LSQPDSM).

Seismic program over shallow-water Guyana acreage

In South America, Viridien and BGP have an agreement with the Ministry of Natural Resources of the Cooperative Republic of Guyana for a large-scale multi-client 3D seismic acquisition and imaging program across shallow-water acreage lots 2, 3 and 4, covering a total area of about 25,000 sq km.

BGP will acquire the data with Viridien performing the imaging using its proprietary workflows such as shallow-water demultiple and TLFWI.

The ensuing new subsurface images and the re-imaged existing seismic will be available to support a future offshore licensing round in the area.
