Abstract The technique of matrix acidification or acid fracturing is commonly utilized to establish communication with natural fractures during reservoir reconstruction. However, this process often encounters limitations due to filtration, which rest

Abstract Condensate blockage significantly impairs gas production in low-permeability reservoirs by reducing gas relative permeability and increasing condensate saturation near the wellbore. Particularly acute in reservoirs with low pressure and perm

Abstract Acidification, as an effective measure to remove blockages and restore oil well productivity, has received widespread concern. However, conventional acid systems can only be used to unblock near‐wellbore zones and are difficult to act on f

Acidizing treatment is commonly used to solve scale problem on production equipment. In this process, Hydrochloric acid (HCl) is often used to treat CaCO3 scale, posing the risk of pipe corrosion due to its high corrosive characteristics. Thus, the p

Sandstone acidizing, overall, increases permeability, though damage may occur during pre-, main-, or post-flush. For example, hydrochloric acid pre-flush can increase permeability by 80%–90%. However, reactions with clays and oils may decrease perm

For many years, the most common acid practice for sandstone acidizing is based on mud acid and dolomite formations using hydrochloric acid. During various stages of sandstone acidizing, different acids react with different minerals, and interactions
