An Enhanced Oil and Gas Recovery in Shale Formations: Enhanced Recovery in Shale Formations Perapon Fakcharoenphol

This research focuses on: (1) explaining the observed increase in well ?ow rate resulting from long shut-in periods in some production wells, and (2) investigating whether water-?ooding can improve hydrocarbon recovery in the greater Bakken formations. Relevant is-sues include pore size and distribution, pore architecture, hydrocarbon composition, salinity, wettability, capillarity, osmotic pressure, and geomechanical alterations of pore connectivity because of water?ooding. Water?ooding may induce an increase in the shear stress followed by rock failure because of an increase in pore pressure and a decrease in temperature. Two numerical models were developed to: (1) investigate the e?ect of gravity, capillarity and osmoticity on phase re-distribution during well shut-in and (2) determine the e?ect of induced stress generated by water?ooding on creation of microfractures to stimulate reservoir performance.
