Mitigating the Health , Safety and Environmental Risks of an Enhanced Oil Recovery Project in a Tropical Forest

The Petroleum Company of Trinidad and Tobago (Petrotrin) has initiated an Enhanced Oil Recovery (EOR) project that will involve steam flooding in the Upper Morne L’Enfer (UMLE) Sands of the Forest Reserve Oilfield, Trinidad. This project involves the conversion of recently drilled wells to injectors, relocation and retrofit of a 30 yearold steam generator from an adjacent oilfield, construction of a gathering station, installation of gas, water, steam, and crude oil pipelines with associated tie-ins. These facilities will be operational for a 20 to 50 year period. During the project-planning phase, an Environmental Impact Statement and a Hazard Operability (HAZOP) Study were conducted to acquire Environmental Management Authority and Ministry of Energy and Energy Industry approvals and address potential safety and environmental risks associated with the project. Baseline data was extracted from an Environmental Impact Assessment that was recently conducted for drilling sixty wells in the same area. Integrating the environmental baseline into the HAZOP study served to identify and rank both potential environmental and safety hazards, which in turn permitted Petrotrin to prioritize risk mitigation strategies. All parties involved in the risk assessments agreed that the team approach used in the HAZOP study permitted a more efficient and effective forum to identify and mitigate both safety and environmental risks as compared to combining results from individual assessments. This paper describes how the UMLE Steam Flood Project’s potential safety and environmental risks were assessed and mitigated. The success in minimizing the risk associated with these hazards serves to demonstrate that oil and gas operations can coexist with sensitive environments.
