Integrated Enhanced Oil Recovery Project
Integrated Enhanced Oil Recovery Project for an Asian National Oil Company
An Asian national oil company wanted to redevelop a mature field, looking at infill wells, waterflooding and enhanced oil recovery. It also wanted to incorporate fluid and core flooding analysis, updates of the static model, a new dynamic model for wells and facility design, sizing and costing. An economic analysis was required.
The operator had a mature oilfield, operating since 1986, with 8 platforms and over 70 development wells. The field was in decline and required a major redevelopment to restore production and develop additional reserves.
SGS deployed a team of petroleum engineers, subsurface geoscientists, process engineers, EOR specialists and a full suite of laboratory services to:
- Carry out an integrated fluid and core flooding program
- Design an in-depth static model review
- Build, history match and develop forecasts with a new dynamic model
- Identify infill well locations
- Develop water flood and EOR pilot and fullfield programs
- Create a scalable process design tool for facility sizing, weight and cost
- Carry out an economic analysis
SGS Solution
SGS successfully carried out a fully integrated fluid and core flooding analysis, subsurface and surface review which included:
- Fluid compatibility analysis
- EOR core flooding tests
- Static and dynamic modeling of uncertainties with history matching
- Infill well and waterflood optimization
- EOR screening, selection and optimization
The key steps in this project included:
- EOR screening
- Fluid compatibility and core flooding analysis
- Updates of the static model and development of a new dynamic model
- Wells and facility design, sizing and costing
- Economic analysis of pilot and fullfield waterflood and EOR development
- Workshops to carry out working sessions, share knowledge and best practices and hand over models to the client team
