Geothermal fracture stimulation technology. Volume 1. Fracturing proppants and their properties

摘要

A review of previously published literature on proppant permeability is presented. This data will be used in the subsequent phases of the geothermal stimulation project. Much information comes from the oil and gas industry which has tested various proppants during the past thirty years over a range of different closure stresses at the lower temperatures found in oil reservoirs. The historical development of proppants is summarized and reviewed and a variety of data on proppants found in today's literature is presented. Also included are several standard test procedures and equipment setups used in measuring proppant properties and in proppant testing.
