The goal of acidizing is to place a reactive fluid in contact with the formation rock in order to remove material on the formation face that may be inhibiting fluid flow into the wellbore.
Conformance technology is the application of processes to reservoirs and boreholes to reduce unwanted water (or gas) production, enhance recovery efficiency, or satisfy a broad range of reservoir management and environmental objectives.
The goal of fracturing in hard rock with low permeability is to create a narrow, long crack in the formation rock to serve as a flow channel to the wellbore.
