Application of in situ CO2 enhanced oil recovery in liquid-rich shale and low-temperature reservoirs
Ogbonnaya, Onyekachi (2023-12)The injection of CO2 presents significant potential for enhancing oil production while minimizing environmental impact by storing CO2 within the oil reservoir. However, the realization of this potential is hindered by ... -
FRAC HIT ANALYSIS IN SHALES: WOODFORD, MERAMEC AND WOLFCAMP FORMATIONS
Gupta, Ishank (2020-07)Frac hit was initially coined to refer to the phenomenon when an infill well fracture interacts with the adjacent well during the hydraulic fracturing process. But, over the years, its use has been extended to any type of ... -
A MICROSCOPIC CHARACTERIZATION OF WETTABILITY IN SHALE KEROGEN WITH VARYING MATURITY LEVELS AND ITS ROLE IN GOVERNING FLUID DISTRIBUTION
Hu, Yinan (2014-12)Kerogen is defined as the insoluble macromolecular organic matter in sedimentary rocks and is a complex mixture of organic chemical compounds. The process of kerogen maturation is accompanied by the loss of functionalized ... -
MODELING AND ANALYSIS OF MULTIPLE LARGE SCALE HYDRAULIC FRACTURES IN ANISOTROPIC ROCK
Sesetty, Varahanaresh (2018-12-14)Shales and mudstones tend to exhibit strong anisotropy so that assuming mechanical isotropy in wellbore failure analysis and completion design strategies in shale can lead to inaccurate results. This dissertation focuses ... -
