... and condensate in 2004 putting the country in the list of hydrocarbon producers worldwide. The field shut down in 2021, and is now considered as one of the most immediate candidates for geological CO 2 sequestration. As a candidate CO 2 storage site, the geomechanical risks are vital to the injectivity...

... ABSTRACT Carbon dioxide (CO 2 ) injection possesses an immense potential for production improvement in heavy oil reservoirs. The primary interest of this work is to investigate the corrosion effect of carbonated water formed by CO 2 and formation water on reservoir rock...

... ABSTRACT This paper investigates the effects of the injection of (relatively) cold CO 2 into a saline aquifer, focusing on the effects that local heterogeneities may have on the geomechanical changes observed during injection. Representative properties of the Smeaheia site, a full-scale...

... ABSTRACT Natural gas hydrate (NGH) has been regarded as important potential energy resource. CO 2 jet erosion HBS can be combined with Radial Jet Drilling (RJD) technology to achieve high efficiency and low-cost gas hydrate mining. The replacement of CO 2 hydrate and CH4 hydrate can also...

... ABSTRACT Cement sheath integrity is critical to the safety and efficiency of CO 2 capture and storage technology. Radial cracking of cement sheath is one of the pathways leading to CO 2 leakage. Cement sheath radial cracking has been little studied, and the models usually ignore the effect...

... ABSTRACT In carbon dioxide (CO 2 ) capture and storage (CCS) technology, one of the goals is to prevent the injected CO 2 from leaking back into the atmosphere. The leakage paths include fractures on the cement sheath sealing the injection well and/or reactivated faults going through...
