... displaced with clean filtered brine, and the well is flowed clean before acidizing begins. Removal of filter cake, carbonate debris, and spent acid must be performed again following the acid treatments. The primary challenge when using these methods is effective openhole coverage (especially in long...

Paper Number: IPTC-15223-MS
... Abstract Successful matrix acidizing requires an even distribution of the acid treatment to remove near-wellbore formation damage throughout the perforated interval. In the absence of diversion, acid treatments tend to predominantly enter the highest-permeability zone, thus bypassing the lower...

..., reservoir temperature, fluids, and heterogeneity, clay type and content, and soaking time. The presence of authigenic clays in reservoirs necessitates proper design of acid treatment to avoid undesirable interaction of these clays with acids and released to cause pore plugging. Therefore, stimulation fluids...
