Well fracturing (hydraulic or acid fracturing) increases effective permeability by creating high-conductivity fractures that connect the wellbore to a larger rock volume. It sits in the completion and ...

It is sometimes necessary to break down perforations by temporarily pumping acid above fracturing pressure to initiate production or injection of a subsequent treatment, such as hydraulic fracturing.

Well acidizing is a stimulation technique that uses acids to dissolve near-wellbore damage or create conductive channels, lowering skin and improving inflow. It fits in the upstream value chain at the ...
