ExxonMobil has selected DeepOcean to provide subsea construction and inspection, maintenance and repair (IMR) services for its operations in the Stabroek block. 

Under the terms of the agreement, DeepOcean will be responsible for planning and executing a diverse range of subsea activities.  

These include subsea construction, jumper installations and comprehensive IMR work.  

The company will utilise the Siem Day multi-purpose support vessel (MPSV) to carry out these operations. 

The vessel is equipped with a crane and advanced technology. It also features a spacious deck, dynamic positioning systems and dual remotely operated vehicle (ROV) spreads. 

Located nearly 200km offshore Guyana, the Stabroek block has been identified as a major global oil and gas find, with recoverable resources surpassing eight billion oil-equivalent barrels.  

ExxonMobil Guyana holds a 45% interest in and operates the block, with Hess Guyana Exploration and CNOOC Petroleum Guyana holding 30% and 25% stakes, respectively. 

DeepOcean president of American operation Tony Stokes said: “This is our first major contract with ExxonMobil in the Americas and our market entry into the exciting Guyana market. We consider this is a confirmation of our team’s expertise and the technical solutions we bring to the table.  

“We are highly committed to delivering high-quality subsea services and solutions, and we look forward to working closely with ExxonMobil Guyana to support their operations in the various field developments in the Stabroek block.” 

In November 2023, ExxonMobil and its partners initiated production at the Payara field within the Stabroek block.  

At a depth of around 2,000m, the Payara field is set to contribute to a total production capacity of approximately 620,000 barrels per day in Guyanese waters. 

Additionally, in the same month, ExxonMobil Guyana awarded Saipem the first contract for the upcoming Whiptail oilfield development, also situated in the Stabroek block at a similar depth of nearly 2,000m.
