Bayphase recently assisted the Guyana government with the review of ExxonMobil’s proposed amendments to its Liza development to accommodate the Gas-to-Energy project.
The UK-based firm said on its website that its work concerned the preparation of two reports summarising its review of the amendment to the Liza field development plan (FPD) and the integration of the Gas-to-Energy environmental and social impact assessment (ESIA).

Bayphase said it conducted an in-depth review of the proposed amendment and supporting documents. The review included:
- The strategy and the development model, as well as the criteria for the choices that have been made by the Operator (with a particular focus on cost effectiveness) and potential alternatives.
- The engineering, geological and geophysical interpretations, simulations, and estimations (with a particular focus on recovery factor efficiency using natural gas injection and available natural gas for export)
- The proposed project schedule (with a particular focus on tail end production).
- The proposed subsea system.
- The well & reservoir management strategy (considering the Government of Guyana’s objective of maximizing the recovery of hydrocarbon resources and of no-gas flaring)
- The proposed oil and gas surface facilities.
- The Health, Safety, Environment and Social (HSES) impacts and proposed mitigation.
- The Abandonment Plan.
- The Sole Consultant risk management strategy.
Bayphase also vetted all costs.
Its ESIA review included assessments of:
- Conformance with Government Environmental Legislation
- Waste Management
- Flaring and impact on Climate Change/Greenhouse Gases
- Adoption of Best Available Technology Solutions
- Waste Management Plan
- Oil Spill Response Plan
- Proposed Plan for management of critical Drilling and Production Operations
- Handling of the discharges of key emissions
- Produced Water
- Oily Water
- Gas Venting.
- Societal Impacts
ExxonMobil Guyana President, Alistair Routledge has said the Stabroek Block co-venturers’ final investment decision on the Gas-to-Energy project will follow the completion of the revision to the Liza development plan.
