FracSleeves
FracSleeves are downhole devices used in hydraulic fracturing to selectively open and close perforation intervals within a wellbore. They are installed in the casing at target fracture zones and enable multistage stimulation by isolating zones until they are individually treated.
A frac sleeve typically comprises a sealed inner sleeve that slides within a fixed outer housing, creating
During completion, the well is perforated across the target zones and enclosed by a frac sleeve and
Common sleeve configurations include mechanical sleeves, ball-activated sleeves, retrievable or fixed-type sleeves, and hydraulic- or electric-actuated
FracSleeves are manufactured from corrosion-resistant steel alloys designed to withstand downhole pressures and temperatures. Their use
