Paper presented at the Abu Dhabi International Petroleum Exhibition & Conference, November 9–12, 2020
Paper Number: SPE-203297-MS
... Field A is a giant carbonate field producing from different reservoirs. As part of the enhanced oil recovery plan, miscible hydrocarbon gas-water injection alternating scheme was employed in two of the main reservoirs. Severe asphaltene deposition is experienced in wells where gas breakthrough is...

Paper Number: SPE-203248-MS
... Abstract Carbonate acidization is the process of creating wormholes in carbonate rocks by injecting acid to increase reservoir permeability and consequent oil production. Nevertheless, some reservoir oils might contain certain amounts of asphaltenes that affect the wormholing process. During...

... Abstract Microsphere injection aiming at in-depth fluid diversion is based on the microsphere retention induced by the particle-rock/brine interaction in hydrodynamic environment. The retention generates steric blocking to the high permeability zones but retards the microsphere migration to the...
