Expro has secured a $20m contract from Pacific Santa Ana to support Petronas’s Chinguetti field phase II plug and abandonment (P&A) contract in offshore Mauritania.

Under the contract, Expro will provide an intervention riser system (IRS) with related surface support equipment and a range of services. These include the subsea well access system, lubricator valve, surface flowhead, umbilicals, topsides control equipment and installation, as well as workover control system package.

In addition, the oilfield services company will deliver an onshore project management team in Kuala Lumpur and then locally onshore in Mauritania.

Pressure and flow control equipment manufacturer Worldwide Oilfield Machine will provide the subsea well access system and technical support team.

Expro subsea vice-president Colin Mackenzie said: “This contract allows Expro to continue to expand our service offering to clients, and provide well access through our existing landing string technology, or now through-riser or riserless systems.

“We welcome the opportunity to support Pacific Drilling by providing our technology and services, which will enhance the efficiency and cost-effectiveness of the field P&A process from their high specification drillship.”

Chinguetti field lies off the coast of the Islamic Republic of Mauritania, North West Africa, in Block 4, production sharing contract (PSC) area B. This is approximately 80km west of the Mauritanian coastline and 90km from the capital, Nouakchott.

The development works are being carried out under a PSC with the Mauritanian Government. It features 21 wells for exploration, appraisal and development, which also includes one commitment well in the Dorade prospect in PSC area C2, and five exploration wells in PSC areas A and B.

The field has been undergoing decommissioning since February 2018 when Ocean Installer won a contract to support BW Offshore in removing Berge Helene FPSO from the site.

The project includes decommissioning of risers and umbilicals on the Chinguetti field.

Pacific Santa Ana is a subsidiary of Pacific Drilling.
