Excessive water production is a well-known problem faced by petroleum industry, combine with carbonate reservoirs that are notoriously difficult...

... for wellbore and reservoir condition. In this research, we proposed a novel correction mathematical model and correction workflow for PTA results of horizontal wells in stratified carbonate reservoir with HPZ. This research innovatively imports production performance analysis and other monitoring methods...

... Abstract In carbonate reservoirs, reactive matrix stimulation creates highly conductive channels, which improves hydrocarbon production. Hydrochloric acid is widely used as stimulation fluid; however, its efficiency at high temperature ranges is limited. Other systems, such as organic acids...

... with anhydrite. Hence, exploration potential exists in some of the graben areas, and this has encouraged recent exploration activities to reveal the true potential of this reservoir. Abstract Matrix acidizing can effectively stimulate carbonate reservoirs, often resulting in skin factors on the order of –3...

... culminations of Miocene carbonate reservoirs in Bakr field. This opened the door to explore new areas within brown fields. As a result, in 2021 an exploratory well-X was drilled. The testing results revealed a thick 100m oil accumulation in a Lower Miocene carbonate section. This resulted in adding a new...

... of 2,000 ft. The permeability of the original carbonate reservoir is set at 0.5 D. The reservoir hosts an oil saturation of 84% in the pore spaces. The initial reservoir pressure is 1,200 psi, and a drawdown of 100 psi is planned for the production phase. The problem statement is defined...

... channels, respectively. Because the fractures and cavities are spatially non-stratified and discretized, the waterflood pattern differs significantly from that in sandstone or porous carbonate reservoirs. It is very essential to construct a spatial well pattern to match the distribution and connectivity...

... The geological reserves of carbonate reservoirs account for about 70% of the world's total Oil and gas reserves, recoverable reserves account for about 50% of the world's recoverable reserves, and oil/gas production accounts for about 60% of the world's total oil/gas production. More than 30...

... Abstract The potential of tuned-composition waterflooding to enhance oil recovery from carbonate reservoirs has been widely investigated in the literature. The consensus is that wettability alteration occurs because of the electrostatic interactions between the carbonate rock surface...
