Paper Number: SPE-210127-MS
... that the RPPG was stable under both static and dynamic gel-natural gas interactions and was stable when being exposed to an acidic environment with an insignificant total percentage weight loss (< 3%). Additionally, the strength of the RPPG was further improved with the longevity of the gas exposure...

... Abstract Casing collapse under external pressure is a complex phenomenon and is one of the governing factors in the tubular design of oil and gas wells. Collapse strength of a casing depends on its outer diameter to wall thickness ratio (i.e. D/t), material Young's modulus, yield stress, shape...

... temperature and increased critical density are observed under confinement. In addition, the effect of fluid-solid interaction strength on phase behavior is studied. It is found that a larger fluid-solid force leads to a more heterogenous density distribution in nanopores. However, the average liquid/vapor...
