BHP will carry out the geophysical survey at its Trion development, with Oceaneering using the DP-2 Ocean Investigator, equipped with their OS-VI AUV and light geotechnical capabilities.


Currently, work is underway and will continue for around 45 days. Oceaneering will also provide light geotechnical services by acquiring 6 m piston core soil samples.

The deepwater depth in the area is considered to be between 1,000-3,000 m.

Before this development, BHP had informed in February that it had set aside $256 million for an offshore well, after a January oil discovery which took place at the Trion field.

Trion was the first well drilled by an international operator in the Mexican deepwater. The drilling was made using the Deepwater Invictus drillship, by Transocean.
