This course provides an in-depth understanding of reservoir drive mechanisms and Enhanced Oil Recovery (EOR) methods and corresponding recovery performances.
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.
No pre-requisistes are necessary to follow this course.
DRIVE MECHANISMS - PRIMARY RECOVERY
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.
Principles and equations.
Generalized Material Balance.
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:
Sources of fluid, well injectivity, injectors pattern.
Expected performance of water and gas injection.
Microscopic efficiency & influence of Capillary Number.
Areal efficiency and influence of Mobility Ratio.
Vertical efficiency and influence of permeability vertical heterogeneity.
ENHANCED OIL RECOVERY
Principles and mechanisms of main EOR methods:
Miscible gas injection.
Screening criteria & economics.
Application - Field cases review.
Upon completion of the course, participants will be able to:
discuss the natural mechanisms of production of oil and gas reservoirs and their corresponding expected performance,
discuss the mechanisms of secondary recovery through water injection and non-miscible gas injection and their related expected performance,
list the main Enhanced Oil Recovery methods and discuss their mechanisms and corresponding expected performance,
describe typical EOR projects workflow and related screening criteria
