Paper presented at the SPE International Conference and Exhibition on Formation Damage Control, February 23–24, 2022
Paper Number: SPE-208848-MS
.... While the severity of the skin may vary from well to well the mechanisms of damage are generally mechanical, chemical, biological, or thermal in nature. Whereas a formation with no damage would have a skin factor of zero a well with serious damage may have a skin factor of 20 or greater. Formation...

... interpretation. From the formation damage study, biopolymer was highlighted as a limiting damage mechanism. This prompted both Equinor and Schlumberger to look at alternative ways to provide rheological support without using biopolymers. A mono-valent biopolymer free reservoir drill-in fluid was designed...

... fluid used to treat formation damage depends on the formation and the damage mechanism. It matters when we start looking at fluid volumes and placement techniques. For vertical wells, treatment volumes typically range from 50 to 150 gallons of acid per foot of perforations. For instance, a 10 foot...
