Special Core Analysis Simulator

Overview

RFDAP SCAS is aSCAL simulator designed to determine and interpret relative permeability and capillary pressure curves through a set of tools, including an automated history matching procedure and simulation for fin tuning. The solution includes the most common experimental approaches, such as unsteady and steady-state core flooding experiments and centrifuge models, and also a multiphase flow approach with a compositional solver for EOR applications. User's Simulations and studies will be directly linked to samples and experimental data information stored in the RFDAP Catalogue central database, keeping track of all the interactions of these processes.

Reservoir Characterization

The main goal of reservoir engineering is to understand how the reservoir-fluid system behaves in order to maximize the ultimate recovery of hydrocarbons in the most economical way. This requires detailed knowledge of the petrophysics of the system, that is, the reservoir geometry, structure, and the interaction between the reservoir and the fluids. Thus, the determination of relative permeabilities and capillary pressures are key fundamentals for the characterization of a reservoir.


EOR Studies

Enhanced oil recovery (EOR) applications can improve the recovery of hydrocarbons without incurring the high costs and risks of new exploration and development projects. Many types of techniques are available, such as low salinity water injection, polymer flooding, CO2 injection, and WAG. However, most of these require a deep understanding of rock and fluid interaction, which can be altered in the presence of different agents. This knowledge can be achieved with RFDAP SCAS, where you are able to reconstruct the whole petrophysics of your reservoir.


Carbon Capture and Storage (CCS)

CCS is the process to capture and inject CO2 into the reservoir, either to act as a EOR method to increase the oil production, or to reduce impact on climate changes, by storing tons of CO2 underground instead of releasing it into the atmosphere. To do this, it is important to understand in detail how the CO2 will behave in the reservoir, once there are several challenges associated with enhancing storage capacity and storage time of CO2, as well as hydrocarbon production. The multiphase compositional solver of RFDAP SCAS can help you to determine these interactions of CO2 within the reservoir system.
