This course provides an in-depth understanding of reservoir drive mechanisms and Enhanced Oil Recovery (EOR) methods and corresponding recovery performances.
Public :
Newly-hired and 2- to 3-year experienced reservoir engineers willing to deepen their knowledge in drive mechanisms and Enhanced Oil Recovery methods; geoscientists, petroleum engineers and production engineers moving towards reservoir engineering.
Level :Awareness
Prerequisite :
No pre-requisistes are necessary to follow this course.
Course Content
DRIVE MECHANISMS - PRIMARY RECOVERY
Oil reservoirs:
Undersaturated oil expansion.
Solution gas drive.
Gas gap drive.
Natural water drive.
Introduction to analytical aquifer models.
Steady-state models - Small Pot model.
Transient models - Hurst & Van Everdingen model and Carter-Tracy model.
Gas reservoirs with and without aquifer.
Material Balance:
Principles and equations.
Generalized Material Balance.
Drive Index.
Campbell and Cole plots.
Application: estimating recovery factors from material balance, checking aquifer and gas cap size, checking accumulation estimate…
DRIVE MECHANISMS - SECONDARY RECOVERY
Reminders about multiphase flow in the reservoir: wettability, capillarity, relative permeability.
Water and non-miscible gas injection:
Principles.
Sources of fluid, well injectivity, injectors pattern.
Expected performance of water and gas injection.
Sweep efficiency:
Microscopic efficiency & influence of Capillary Number.
Areal efficiency and influence of Mobility Ratio.
Vertical efficiency and influence of permeability vertical heterogeneity.
