SelectEOR Software: An EOR Screening Tool Overview

Enhanced Oil Recovery (EOR) techniques are crucial for maximizing hydrocarbon recovery from mature reservoirs. Selecting the optimal EOR process requires rigorous screening and prediction, often presenting complex challenges due to varied reservoir conditions and fluid properties. The SelectEOR software, originally developed by the Alberta Research Council (ARC), stands as a historically significant tool designed to assist reservoir engineers and simulation specialists in this critical screening phase.

This article details the capabilities and unique aspects of SelectEOR, offering insight into its approach to EOR process selection and performance prediction. It focuses on the software’s comprehensive integration of classical analytical methods for early-stage project evaluation, making it a valuable reference for understanding traditional EOR screening workflows.

What is SelectEOR Software?

SelectEOR is a specialized screening software engineered to evaluate a wide range of Enhanced Oil Recovery processes. It provides a structured environment for comparing the applicability and potential effectiveness of different EOR methods based on user-defined reservoir and fluid properties. Known for its comprehensive bundling of classical analytical prediction methods, SelectEOR has served as a reference point for early-stage EOR project evaluation.

Core Capabilities: A Broad Spectrum of EOR Screening

SelectEOR is distinguished by its ability to screen 17 distinct EOR processes and generate predictions using 14 different prediction methods. This breadth allows engineers to survey a significant portion of the EOR landscape within a single application, facilitating initial assessments of various EOR options.

Waterflooding Prediction Methods

For conventional waterflooding, SelectEOR integrates five well-established prediction methods, allowing for varied analytical perspectives on sweep efficiency and recovery projections. These methods provide a robust framework for understanding and predicting waterflood performance under different reservoir characteristics:

• Dykstra-Parsons
• Craig-Geffen-Morse
• Higgins-Leighton
• Dietz
• Bush-Helander

Chemical EOR Processes

The software covers key chemical EOR approaches, providing screening capabilities for methods that alter fluid properties or mobility ratios to improve sweep efficiency and displace residual oil. These include:

• Polymer flooding
• Surfactant/polymer (SP) flooding
• Alkaline/surfactant/polymer (ASP) flooding

Gas Injection EOR

SelectEOR supports both miscible and immiscible gas injection techniques, which are vital for recovering oil by reducing viscosity, swelling oil, or maintaining reservoir pressure. The software’s capabilities span various gas types:

• Miscible Gas Injection: Includes hydrocarbon, CO2, N2, and air injection.
• Immiscible Gas Injection: Covers CO2, N2, and flue gas injection.

Thermal EOR Processes

For heavy oil and bitumen reservoirs, the software includes critical thermal methods designed to reduce oil viscosity and improve mobility, making these challenging resources recoverable. These methods are essential for evaluating steam-based and combustion-based recovery strategies:

• Steam drive
• Steam-Assisted Gravity Drainage (SAGD)
• In-situ combustion

The SelectEOR Differentiator: Breadth of Analytical Methods

What sets SelectEOR apart from many other EOR screening tools is its emphasis on the breadth of named classical prediction methods rather than deep, single-method specialization. It is recognized for documenting the exact underlying analytical correlations by name, providing transparency into the calculations. This approach, particularly evident in its extensive suite of waterflood correlations, offered engineers a consolidated resource for applying multiple traditional analytical models within one software environment, facilitating comparative analysis based on established theories.

SelectEOR’s strength lies in its comprehensive integration of established analytical EOR prediction methods, offering a transparent framework for early-stage project screening.

Historical Context and Legacy Status

Originally developed by the Alberta Research Council (ARC), a Canadian provincial research organization (which later became part of Alberta Innovates), SelectEOR gained recognition within the petroleum engineering community. While it is no longer actively maintained or updated, its historical significance as an EOR screening tool is noteworthy. Public industry forums indicate that engineers continued to seek licenses for it into the mid-2010s, underscoring its long-standing familiarity and utility within the industry for traditional analytical EOR evaluation. As a result, petroleumsoftware.ir includes it as a valuable reference in its comprehensive software directory.
