Fast, comprehensive evaluation

Effective evaluation of EOR alternatives can substantially increase value and decrease development risk—for both new and mature assets. To quickly provide a reliable ranking of EOR techniques, Schlumberger developed the EORt* enhanced oil recovery method evaluation and screening tool. This process-based, interactively guided tool is used by

Schlumberger petrotechnical experts to conduct detailed data and reservoir evaluation with  a comprehensive process that helps guide every step of EOR screening and implementation.

Supporting different reservoir types, from single-porosity to naturally fractured dual-porosity reservoirs, the EORt tool incorporates detailed documentation about specific displacement processes. This extensive database, in combination with embedded knowledge and optimized workflows, enables efficiently performing geologically consistent screenings for selecting   the best EOR solution for the asset. Further, Schlumberger EOR specialists work in close collaboration with in-house teams to ensure that all available reservoir information is effectively used.

Using the EORt tool enables

• rapid assessment of the enhanced recovery potential of each area of the reservoir
• maximized conformance by matching EOR and reservoir architecture
• quantification of the validity of rock and fluid data for reliable EOR evalua

The tool can be used to perform a qualitative and quantitative ranking of all plausible EOR alternatives. It uses multidimensional screening, combining detailed analyses of the field’s current saturation conditions and rock-type distribution with past project information that is pulled from a database of more than 2,700 EOR projects. The EORt tool uses analytical and numerical methods to rank the most suitable EOR alternatives for the field.

Reservoir architecture and displacement mechanisms

Locating potential movable oil in the reservoir and analyzing displacement potential in gravity- or capillarity-dominated flows allows the EORt tool to help maximize reservoir conformance and, therefore, increases the potential for EOR success. The tool is used  to analyze present, past, and future behavior of the reservoir in terms of recovery mechanisms, flow patterns, and geological settings.

Oil displacement in the reservoir is dominated by the balance of capillary, gravity, and viscous forces. A successful screening requires the detailed understanding of these forces, particularly in highly heterogeneous reservoirs where depositional environments can heavily influence the advancement of any displacement agent.

The EORt tool considers this balance when screening each EOR method, ensuring that every technique can achieve its maximum potential.
