Predicting the Rate by which Suspended Solids Plug Geothermal Injection Wells

PDF Version Also Available for Download.

Description

Standard membrane filtration tests have been used by the oil industry for more than 20 years to evaluate injection well performance. Published analytical models are also available fore relating filtration data to injector lifetimes. We have utilized these techniques to evaluate injection at the Salton Sea Geothermal Field, Southern California. Results indicate that direct injection into reservoir zones with primary porosity is not feasible unless 1-micrometer or larger particulates formed during or after the energy conversion process are removed. Membrane filter tests are useful in evaluating injectivity of geothermal effluents. Techniques are available for estimating injector half-life utilizing filtration data. ... continued below

Membrane filter tests are useful in evaluating injectivity of geothermal effluents. Techniques are available for estimating injector half-life utilizing filtration data. Injection of brine with suspended solids is not feasible in reservoir zones with primary porosity. However, long-term injection of brine and suspended solids can apparently be achieved in fracture zones. 1 tab., 3 figs., 12 refs.
