... in the fingering regions. We performed parametric studies to investigate the effects of pad fluid viscosities and acid injection rates on acid fracture conductivity. We found that a higher viscosity pad fluid and a higher acid injection rate help acid to penetrate deeper in the fracture and result in a longer...

...), where the acid injection rate(s) were constant and the pressure in decline. However, limited study focused on wormhole development at constant injection pressure (CIP), where the acid injection rate increased with time. Therefore, the primary objective of the present work is to investigate the benefits...

... intervals untreated. This problem can be more significant as the contrast in permeability increases within the target zones. Diverting materials, such as surfactant based-acids, plays an important role in mitigating this problem. Acid injection rate was found to be a critical parameter to maximize...

... Abstract Our main result is the discovery of an optimum acid injection rate to obtain acid breakthrough in linear corefloods of carbonates using a minimum total acid volume. Low rates result in acid spending at the core surface while high rates result in the formation of multiple, highly...
