Analytical solution for Joule-Thomson cooling during CO2 geosequestration in depleted oil and gas reservoirs.

Mathias, S.A. and Gluyas, J.G. and Oldenburg, C.M. and Tsang, C.-F. (2010) 'Analytical solution for Joule-Thomson cooling during CO2 geosequestration in depleted oil and gas reservoirs.', International journal of greenhouse gas control., 4 (5). pp. 806-810.

Abstract

Mathematical tools are needed to screen out sites where Joule–Thomson cooling is a prohibitive factor for CO2 geo-sequestration and to design approaches to mitigate the effect. In this paper, a simple analytical solution is developed by invoking steady-state flow and constant thermophysical properties. The analytical solution allows fast evaluation of spatiotemporal temperature fields, resulting from constant-rate CO2 injection. The applicability of the analytical solution is demonstrated by comparison with non-isothermal simulation results from the reservoir simulator TOUGH2. Analysis confirms that for an injection rate of 3 kg s−1 (0.1 MT yr−1) into moderately warm (>40 °C) and permeable formations (>10−14 m2 (10 mD)), JTC is unlikely to be a problem for initial reservoir pressures as low as 2 MPa (290 psi).
