Geothermal and heavy-oil resources in Texas: direct use of geothermal fluids to enhance recovery of heavy oil Geothermal and heavy-oil resources in Texas: direct use of geothermal fluids to enhance recovery of heavy oil 1993

In a five-county area of South Texas, geopressured-geothermal reservoirs in the Paleocene-Eocene Wilcox Group lie below medium- to heavy-oil reservoirs in the Eocene Jackson Group. This fortuitous association suggests the use of geothermal fluids for thermally enhanced oil recovery (TEOR).

Comparison of Empirical Models for Calculating the Vuggy Porosity and Cementation Component of Carbonates from Log... Comparison of Empirical Models for Calculating the Vuggy Porosity and Cementation Component of Carbonates from Log... 1993

Formation evaluation in heterogeneous carbonate reservoirs is complicated by the presence of multiple pore types. Acoustic properties, Archie cementation exponents, and permeability transforms differ according to pore type.
