Halliburton Wins Integrated Drilling and Completion Contract for GranMorgu Deepwater Development Offshore Suriname
In a September 2025 announcement, Halliburton (NYSE: HAL) disclosed that it has been awarded an integrated drilling and completion services contract for the GranMorgu offshore development operated by TotalEnergies. The agreement covers the full life‑cycle of well construction for the deepwater field located in Block 58, approximately 150 kilometers off the coast of Suriname.
Project Overview
The GranMorgu field is one of the latest discoveries in the Guyana‑Suriname basin, a region that has attracted significant investment due to its high‑quality reservoirs and favorable fiscal terms. TotalEnergies, as operator, plans to develop the field with a series of subsea wells tied back to a floating production, storage and offloading (FPSO) unit.
Key facts about the project:
- Location: Block 58, offshore Suriname, water depths ranging from 1,200 to 1,800 meters.
- Operator: TotalEnergies Suriname B.V.
- Development concept: Subsea wells connected to an FPSO via flexible risers and umbilicals.
- Estimated recoverable resources: Preliminary assessments suggest several hundred million barrels of oil equivalent.
Halliburton’s Integrated Execution Model
Halliburton said it will deploy an integrated digital and automated execution framework that brings together planning, engineering, and field operations into a single workflow. The approach is designed to:
- Optimize well placement through advanced geosteering and real‑time seismic imaging.
- Reduce non‑productive time (NPT) by automating routine drilling tasks and enabling remote monitoring from Halliburton’s digital operations centers.
- Improve hydrocarbon recovery by maintaining precise wellbore trajectories and minimizing formation damage.
- Lower overall project costs through predictive maintenance and data‑driven decision making.
The company highlighted that the contract leverages its Halliburton Digital Suite, which includes the DecisionSpace® platform for subsurface modeling, Drillbench™ for real‑time drilling analytics, and iControl™ for remote wellsite supervision.
Commitment to Local Capacity Building
Beyond the technical scope, Halliburton emphasized that the award includes provisions for developing local capabilities. The company plans to:
- Invest in training programs for Surinamese engineers and technicians in partnership with local technical institutes.
- Source a portion of materials and services from Surinamese suppliers, thereby supporting the domestic supply chain.
- Collaborate with TotalEnergies on community outreach initiatives focused on education and environmental stewardship.
Franco Delano, Halliburton’s Vice President for the Caribbean, noted in the press release:
“The award reflects the value of integrated execution, collaboration and digital technology in complex deepwater developments. The GranMorgu project demonstrates how aligned teams and advanced well construction capabilities support the safe and efficient delivery of wells while maximizing asset value for our customers.”
Industry Context and Significance
Deepwater projects in the Guyana‑Suriname basin have become a focal point for international oil companies seeking to offset mature basin declines elsewhere. According to Rystad Energy, offshore Suriname could contribute up to 0.5 million barrels per day to regional production by 2030 if current discoveries are brought online.
Halliburton’s track record in deepwater operations includes recent contracts for the Liza phase 2 development offshore Guyana and the Johan Sverdrup field in the North Sea. The GranMorgu award reinforces the company’s position as a trusted partner for high‑complexity, technology‑driven offshore programs.
Looking Ahead
With the contract now in place, Halliburton will begin mobilizing its integrated teams and digital tools to support the early engineering phases of GranMorgu. First oil is anticipated in the latter half of the decade, contingent on successful drilling, completion, and infrastructure installation.
For stakeholders, the development offers a clear example of how digital transformation, collaborative execution, and local empowerment can converge to deliver value in challenging offshore environments.
