GranMorgu oil development is located on Block 58, around 150km off the coast of Suriname.
TotalEnergies, the operator of the block, announced the Final Investment Decision (FID) for GranMorgu in October 2024.
Recommended White Papers
In the local Sranan Tongo language, GranMorgu means ‘new dawn’ and ‘Goliath Grouper’, a fish found in the coastal waters of Suriname.
The project will entail an investment of around $10.5bn. Construction and installation works for the project will take approximately four years.
TotalEnergies expects that with the agreed development timeline, the project will produce first oil in 2028.
Once onstream, GranMorgu will support job creation and development of the local economy. The project is expected to create 2,000 direct and 4,000 indirect jobs.
Over the estimated life of the production field, Suriname will be benefitted with between $16bn and $26bn of net income consisting of royalties, profit oil, and taxes.
GranMorgu Developers
TotalEnergies holds 50% interest in offshore Block 58. The remaining 50% stake is with US-based hydrocarbon exploration focused company APA Corporation.
Under a production sharing contract, Suriname’s national energy, oil & gas company Staatsolie can participate in the project holding maximum 20% interest.
Staatsolie agreed to contribute to the project from FID. The company is expected to finalise its interest by June 2025.
GranMorgu Project Development Details
The offshore project will involve the development of the Krabdagu and Sapakara oil discoveries. Exploration and appraisal campaign on the fields were completed in 2023.
The fields are expected to host recoverable reserves of more than 750 million barrels.
The Field Development Plan (FDP) of the project, approved by Staatsolie, includes the development, technical details, and a timeline for the project.
The development will include a Floating Production Storage and Offloading (FPSO) unit with a production capacity of up to 220,000 barrels of oil per day. It will be connected to the subsea infrastructure located at a water depth of 100m to 1,000m.
Around 32 wells will be drilled, of which 16 wells will produce oil and the rest will inject back water and gas with oil.
The scope of works during the construction period will include drilling the wells, installing subsea installations, laying pipelines and placing the modules on the FPSO.
Two drilling machines are expected to be deployed for drilling wells.
The project partners plan to involve local companies in logistics, well services, as well as the installation and operations of the FPSO and subsea systems.
TotalEnergies has also conducted an Environmental and Social Impact (ESIA) study, that included public consultations with the various stakeholders. As of October 2024, the ESIA document is being assessed by the National Environmental Authority (NMA) of Suriname.
GranMorgu FPSO Details
The FPSO for the project will be designed to minimise the impact on the environment. The vessel will have an all-electric FPSO configuration ensuring zero routine flaring and full reinjection of gas into the reservoirs.
The waste heat recovery and water-cooling units of the FPSO will be optimised for greater efficiency.
Additionally, the FPSO will be equipped with a permanent sensor-based methane detection and monitoring system. The development aims to keep Scope 1 and 2 emissions intensity below 16 kg CO2e/boe.
In future, the 220,000 barrels of oil per day-unit can be tied-back to other developments to increase production.
Based on Krabdagu and Sapakara reserves, production period is estimated to be 20-25 years.
Contractors Involved
The Front-End Engineering and Design (FEED) contract for the FPSO hull was awarded to SBM Offshore.
In October 2024, TotalEnergies E&P Suriname awarded a two-year contract with a one-year extension option to ADC Energy for the GranMorgu Project. Under the contract, ADC will help in selecting up to three offshore drilling rigs for the GranMorgu development.
The contract works will be carried out by ADC supported by its Aberdeen headquarters and ADC Rig Inspection Americas in Houston.
