Abstract Distributed Temperature Sensing (DTS) was used to evaluate a novel sandstone stimulation treatment based on exothermic reaction. The technology is based on injecting in-situ heat generating fluid (IHGF) that generate in-situ heat i.e., ~>400F and nitrogen pressure to mobilize and remove near well bore damage in sandstone formations.The microscopic evaluation of quartz sandstone concrete was found to have micro voids that hindered heat transfer between the particles which was assumed to give a thermal insulation property .

Grey Berea, Bandera Brown, and Kirby sandstone were used to represent low, moderate and high clay content, respectively. Core flooding experiments were conducted using CO 2, brine (7 wt % NaCl + 5 wt % KCl + 5 wt % CaCl 2 .2H 2 O) and n-C 10 at a temperature and .This paper discusses the different reasons sandstone reservoirs can have low resistivity. Clean bearing sandstone has high resistivity, but when this rock contains shale, or heavy minerals such as pyrite, the resistivity can become low. This resistivity change depends on .

A comprehensive evaluation index is established and used to judge the co-mining feasibility of 14 wells (J-1 to J-14) in the No. 8 coal seam and adjacent sandstone layers in the Linfen block.Different fluids were used as fracturing fluids in shale and sandstone formations, including the use of CO 2, N 2 and CO 2 foam, slick water, crosslinked solutions, and oil-based fracturing fluids. The objective of this study is to develop an experimental setup to measure the breakdown pressure to initiate the fractures in shale and tight .
