Global geophysical services company TGS has kicked off a major 3D seismic reprocessing programme over mature, hydrocarbon-producing areas in the US Gulf of Mexico.

TGS said the programme - dubbed Sophies Resolve Refocus 3D - includes 6175 square kilometres of reprocessed 3D seismic data to provide a high-quality regional product, "helping E&Ps further explore new and existing plays in this area".

The project, which is supported by industry players, marks the next phase of high-quality imaging over the South Timbalier, Grand Isle and Ewing Bank areas.

Kristian Johansen, chief executive at TGS, said: "The Gulf of Mexico remains a top priority for TGS. By utilizing the latest imaging techniques, this program provides our customers with the most comprehensive view of the subsurface so they can make the best decisions about their investments. Having the best possible understanding of the subsurface also allows TGS to optimize future acquisition investments."

The project began in the current quarter, with final data available in the third quarter next year.
