Petrel EOR screening and decision advisory system

Honor the latest reservoir understanding in identifying, evaluating, and ranking EOR methods

Overview

Effective evaluation and recognition of the potential for enhanced oil recovery can substantially increase reservoir value and mitigate development risk. The Petrel™ EOR screening and decision advisory system plug-in robustly identifies, evaluates, and ranks the EOR technologies relevant for the reservoir, with consideration of both conventional single porosity as well as dual-porosity naturally fractured reservoirs. The evaluation is performed by using a combination of analytical and numerical methods to enable honoring the up-to-date reservoir understanding

Guided two-stage workflow with multiple EOR methods

Screening is efficiently conducted by the Petrel EOR screening and decision advisory system in two stages.

The first stage, which is also suitable for reservoirs where data is limited, uses analytical methods to compare and rank plausible EOR technologies through displacement efficiency estimations and reference to a comprehensive database with more than 2,700 documented EOR projects.

In the second stage, numerical models are employed to quantify the EOR potential, including simple economics under representative reservoir conditions of saturation and heterogeneity. This guided workflow followed by the advisory system is particularly effective for quickly assessing the EOR prospectivity of your reservoirs.
