Abstract Oil and gas operations in sedimentary basins have revealed the occurrence of significant temperature anomalies at depth, raising the possibility of major geothermal resource potential in the sedimentary sequences. The efficient development of such a resource may require enhancement by hydraulic stimulation. However, effective stimulation r...
Carbon Capture and Sequestration (CCS) has been widely adopted as a key technology to mitigate anthropogenic greenhouse gas emissions and to meet the 2050 net-zero carbon emission target. However, the long-term CO2 storage security and potential leakage in geologic formations still pose a major concern to the commercial implementation and viability...

In bio-mediated geotechnical techniques, the estimation of microbially altered geomechanical properties has mostly been conducted at core-scale due to the complexity of in situ field-scale measurement of biogeomechanical properties. However, the successful in situ field application of this emerging field of geomechanics relies on proper upscaling o...
Produced water (PW) is an undesirable product generated during oil and gas production. More than 56% of the PW volume generated in the United States is disposed of either into the subsurface non-productive water-bearing reservoir (referred to as Saltwater Disposal well, SWD) or through other means. In the Permian Basin, 38–50% of the PW water volum...
Produced water (PW) is an undesirable byproduct generated from oil and natural gas production. Due to the large volume produced, managing its disposal is challenging. Generally, PW is used internally for oil and gas operations while different types of means dispose of the remaining volumes. Recently, there has been a need to repurpose the volume of...
Tight formations such as the Three Forks Formation in the Williston Basin have very low primary recovery factors (typically 10% or less), which potentially leave billions of barrels stranded in the reservoir. According to the results of gas enhanced oil recovery (EOR) pilot tests that have been conducted in the Bakken Formation, cyclic gas injectio...
