CO2 is now considered as a novel heat transmission fluid to extract geothermal energy. It can be used for both energy exploitation and CO2 geological sequestration. Here, a 3-D, “two-spot” pattern wel...
RIVERSIDE, Calif. — In 2009, a borehole drilled at Krafla, northeast Iceland, as part of the Icelandic Deep Drilling Project (IDDP), unexpectedly penetrated into magma (molten rock) at only 2100 meter...
Clay mineralogical X-ray diffraction and electron microprobe studies have been carried out on separated <2 ?m fractions from cutting and core material from three wells in the Chipilapa geother- mal ...
Abstract: The chemical composition of hydrothermal chlorite was determined by means of more than 200 electron microprobe analyses (EMPA) in almost all of the 70 chlorite-bearing samples taken from 5 b...
A smectite rich in ferrous iron and low in aluminum occurs abundantly in the Red Sea Geothermal Deposits, and appear to be forming at present.Chemical analyses and Mossbauer spectra indicate the miner...
