The Effects of Non-Condensible Gas and Salinity on Steam Adsorption
Abstract/Contents
- Abstract
- Water adsorption in geothermal reservoir materials was investigated by a transient flow technique using steam and C0 2 gas. Theoretical and experimental results in- dicate that water adsorption exists in the vapor-dominated type of reservoir, but experiments in the past have been limited to pure gases.The common presence of C02, a non-condensible gas, in a geothermal reservoir neces- sitated a study of the effect of partial GO2 concentration on adsorption. Experimental laboratory work using a crushed Geysers rock sample at low pressure was carried out. Transient pressure exerted by steam pressure inside the sample was measured against time during a desorption process. It was found that the partial presence of COS did not significantly affect the adsorption of water.A 5% by weight of saline solution was added to the rock sample. Addition of salt to the sample enabled it to adsorb more mass of steam per unit mass of rock sample. This inference was obtained by means of a nonlinear regression program, which matched to the results of a one-dimensional geothermal simulator.This series of experiment used different sizes of sample, which came from The Geysers geothermal wells.
