Sandport Reclosable Frac Sleeves

Kobold’s reclosable frac sleeves are only 80.4 cm (31.7 in.) in length and weigh an average of 32.9 kg (72.5 lb). The reclosable frac sleeves provide a reliable solution during the initial fracture and ongoing wellbore production management. During completions, the Sandport sleeves can be opened once or closed post-frac. This provides the flexibility to optimize well production, or to implement a water flood strategy during the well’s lifecycle.

This completion method allows for future wellbore management to re-energize production or close off water thief zones. Closing sleeves after the frac, can also reduce the requirement for post-frac clean-out runs for increased operational savings.
