Paper presented at the 55th U.S. Rock Mechanics/Geomechanics Symposium, June 18–25, 2021
Paper Number: ARMA-2021-1196
... microannulus that more realistically reflects the field. 1. Introduction A wellbore is a channel that is mainly used for the extraction of fossil energy, and it is also used as a pathway to inject carbon dioxide into a subsurface storage site. Well designs usually involve multi-size casing and cement...

Paper presented at the 53rd U.S. Rock Mechanics/Geomechanics Symposium, June 23–26, 2019
Paper Number: ARMA-2019-1936
... ABSTRACT: Carbon dioxide (CO 2 ) fracturing has the advantage of creating complex hydraulic fractures (HFs). However, the characteristics of HFs induced by supercritical CO 2 (Sc-CO 2 ) in tight sandstones remain unclear. In this study, laboratory true triaxial fracturing experiments were...

Paper Number: ARMA-2019-2143
... continental shale samples under different stresses. Both water and super critical carbon dioxide (SC-CO2) were used as the fracturing fluids. The fracture propagation characteristics on the surfaces were analyzed. The electronic microscope and three-dimensional scanner were also used to observe the main...

Paper Number: ARMA-2019-1749
... ABSTRACT: The injection of carbon dioxide to improve the production of shale gas has become one of the key technologies, but its adsorption and desorption mechanism is relatively complicated. In this paper, the adsorption mechanism is studied through a combination of micro-scale numerical...

Paper Number: ARMA-2015-274
... Abstract Supercritical carbon dioxide (SC-CO 2 ) jet can break rocks with higher rates and lower threshold pressures than water jet due to the unique fluid properties. The abrasive SC-CO 2 jet technique, which is formed by adding abrasive particles to the SC-CO 2 jet, was proposed...

Paper Number: ARMA-2012-232
... ABSTRACT: Carbon dioxide (CO2) sequestration into deep underground reservoirs such as saline aquifers, oil reservoirs and coal seams have found out to be one of the best practical solutions to reduce significant amount of greenhouse gases from the environment. The success of any large scale...
