Providing interpretations and evaluating incremental oil potential
Client : Petrobras
Location: Peru
Objective: Determine the best production strategy from a naturally fractured dual porosity reservoir
Petrobras, the Brazilian energy giant, boasts some of the most advanced technology in
the oil industry in such areas as deepwater development and reservoir engineering.
Petrobras engaged Knowledge Reservoir to do a study of the complex dual porosity
Mogollón Formation in its operating area in the Talara Basin in Northern Peru.
The study objectives included:
• Estimating original oil in-place (OOIP).
• Providing geologic and engineering interpretations, a complex challenge given the
dual porosity nature of the reservoir.
• Formulating field development alternatives.
• Estimating incremental oil production from each field development alternative.
• Selecting wells as re-fracturing candidates.
A simulation sector model was used over a representative portion of the reservoir with
the objective of understanding fluid flow and oil recovery dynamics. The model was used
to show the benefits of incremental field development projects. There were 30 wells
selected as re-fracturing candidates based on formation-specific technical and operating
criteria. Despite the complex nature of the reservoir, good IOR and EOR potential was
identified for both water injection and gas injection.
