1/7/2015, · When this happens, it can be readily concluded that ,acidizing, does not work well and is expensive. However, ,acidizing, does work very well to remove damage when the type of damage is known, and known to be acid-removable, the ,treatment, is properly designed and properly executed. Extreme damage may require more than what is discussed.

26/4/2017, · ,Acidizing, works well to remove damage when the type of damage is known, the ,treatment, is designed properly, and it is properly executed. Extreme damage may require more than what is discussed. Actions required may include a chemical soak and swabbing the soak back before ,acidizing, or reperforating, and/or ,fracturing, to bypass damage.

Reservoir rock is composed of fine sandstone and siltstones interlayered with thin shales. Average reservoir porosity is ~7% and average permeability is ~0.07 mD. The gross reservoir thickness is ~180-220m in this fault block. Wells D1 and D2 were completed by ,acidizing, and gel ,fracturing,; test production was ~15-27 ×10 4 m 3 /d.

The ,flowback, rate is dictated by the necessity to keep the fractures open. When proppant is used, the ,fluid flowback, rate must be slow enough to prevent viscous ,fluid, forces from pulling proppant out of the fractures. Thus, both conventional and unconventional HF ,flowback, operations occur at similar rates.
