Water coning in porous media reservoirs for compressed air energy storage

“…The selected reference values of these parameters are given in Table 1. These values are consistent with the values used in previous analyses of compressed air energy storage in porous media reservoirs (Smith, Wiles, Loscutoff 1979;Wiles March 1979;Wiles Oct. 1979). The reference functions relating relative permeability and capillary pressure to saturation are provided.…”

“…Previous investigations have dealt with one-and two-dimensional modeling of dry reservoirs (Smith, Wiles, Loscutoff 1979, Wiles October 1979. A one-dimensional modeling of water wet reservoirs has also been performed (Wiles March 1979).…”

“…The development of the cycle is described in the report issued on that analysis. (Smith, Wiles, Loscutoff 1979).…”

“…The initial code was based upon a one-dimensional (radial), single-phase (air) approximation of the reservoir. It was used to evaluate the sensitivity of reservoir performance to fundamental reservoir properties, geometry, and operating conditions (Smith, Wiles, Loscutoff 1979). The second code was one-dimensional (radial) and twophase (air-water) although liquid mobility was not included.…”

Thermodynamic and hydrodynamic response of compressed air energy storage reservoirs: a review

“…Numerical solutions of the two-phase fl ow equations for a partially penetrating single-well subject to a weekly cycle were presented by Wiles and McCann (1981) . The work made part of an extensive CAES research effort conducted at the Pacifi c Northwest Laboratory, USA (e.g., Smith et al 1979, Wiles 1979. The reservoir pressure fl uctuations were found to be highly sensitive to the well screen length.…”
