The Screening of Oil Reservoirs for Enhanced Oil Recovery Processes

Introduction

The Screening of Oil Reservoirs for Enhanced Oil Recovery Processes

COURSE OBJECTIVES:

After completion of the course, the participants will be able to:

• Explain the main categories of EOR processes and their mechanisms of improving oil recovery.
• Describe the critical role of reservoir screening in the overall EOR project life cycle.
• Identify key reservoir and fluid properties that control EOR applicability, including depth, temperature, pressure, oil gravity, oil viscosity, and formation water salinity.
• Interpret geological and petrophysical information (porosity, permeability, heterogeneity, fractures, layering) for use in EOR screening.
• Apply standard screening criteria and guidelines for gas injection, miscible EOR, chemical flooding, polymer floods, and thermal methods.
• Evaluate laboratory and PVT data requirements to support EOR screening and feasibility assessment.
• Construct screening matrices and ranking tables to compare different EOR options for a given reservoir or portfolio of reservoirs.
• Assess the impact of rock fluid interactions, wettability, capillary pressure, and relative permeability on EOR process selection.
• Recognize operational constraints such as injectivity, facilities limitations, chemical handling, and water quality in the screening stage.
• Incorporate economic indicators, uncertainties, and risk factors into EOR screening and preliminary project evaluation.
• Distinguish between primary, secondary, and tertiary processes and understand when EOR screening should be initiated in a field’s life.
• Interpret results from pilot tests, simulation studies, and field trials to refine screening decisions and update project rankings.
• Develop structured workflows and checklists for screening reservoirs at the field and portfolio level.
• Communicate screening outcomes and recommendations effectively to management, partners, and multidisciplinary teams.
• Review case histories of successful and unsuccessful EOR projects to extract screening lessons and best practices for future applications.
