A Comprehensive and Applied Course in Waterflooding (RE09)

Course Level: Advanced

This is an intensive, applied course in waterflood design and management. Certain theoretical aspects of waterflooding (e.g. Buckley-Leverett fractional flow) will be briefly covered. Topics covered will include: reservoir performance analysis, well injectivity estimates, waterflood candidate selection, waterflood forecasting (includes hands-on analytical and simulation modeling), impact of heterogeneity on waterflooding, selection of waterflood pattern (technical and economic considerations), waterflood performance analysis (includes analysis of production decline and fall-off tests), and design of waterflood injection and production facilities. Participants will also work many exercises.

OUTLINE:

Introduction to waterflood
-  The total system – injection, production, pattern
-  Factors affecting optimization of the total system
-  Waterflood design - a multi-disciplinary effort
-  Waterflood patterns
-  Operational constraints – waterflood offshore

Reservoir engineering fundamentals
-  Why waterflood?
-  Material balance and reservoir pressure prediction
-  Flow regimes - diffuse and segregated flow
-  Injectivity/productivity calculations for different pattern types
-  Areal and vertical sweep efficiency, displacement efficiency, recovery efficiency

Analytical models
- Waterflood design. Factors to consider in selection of pattern type and size.
- Analytical forecasting models: theory and application.

Simulation
-  Hands-on waterflood reservoir simulation.
-  Class will develop and run 3D model of one-eighth of 5-spot pattern using
   ECLIPSE 100 (input data will be provided).
-  Compare reservoir simulation and analytical model results.

Pattern selection
-  Discounted cashflow analysis
-  Selection of pattern based on economic criteria and operational constraints

Waterflood surveillance
- Decline curve analysis; injectivity and fall-off test analyses, Hall plot
- Infill drilling

Overview of waterflood facilities
-  Reservoir Data Requirements for Waterflood Planning
-  Waterflood Monitoring and Technology
-  Facilities
-  Tubular Goods into the Reservoir
-  Microbiological Control of Waterfloods
-  Scaling Issues

WHO SHOULD ATTEND

The course is meant for petroleum engineers who wish to master the design and management of waterflooding. It is ideally suited for engineers with at least 3 years reservoir/production engineering experience. Knowledge of ECLIPSE 100 is advantageous but not critically essential.
