Wellbore flow model for carbon dioxide and brine

PDF Version Also Available for Download.

Description

Wellbores have been identified as the most likely conduit for CO{sub 2} and brine leakage from geologic carbon sequestration (GCS) sites, especially those in sedimentary basins with historical hydrocarbon production. In order to quantify the impacts of leakage of CO{sub 2} and brine through wellbores, we have developed a wellbore simulator capable of describing non-isothermal open well flow dynamics of CO{sub 2}-brine mixtures. The mass and thermal energy balance equations are solved numerically by a finite difference scheme with wellbore heat transmission handled semianalytically. This new wellbore simulator can take as input the pressure, saturation, and composition conditions from reservoir ... continued below

The mass and thermal energy balance equations are solved numerically by a finite difference scheme with wellbore heat transmission handled semianalytically. This new wellbore simulator can take as input the pressure, saturation, and composition conditions from reservoir simulators and calculate CO{sub 2} and brine fluxes needed to assess impacts to vulnerable resources. This new capability is being incorporated into the Certification Framework (CF) developed for risk assessment of GCS sites.
