About
Nova Frac Sliding Sleeve is a high-stage count, intervention less, one size ball frac port featuring a dissolvable ball. Because the activation ball is dissolvable the wellbore production will be unrestricted after dissolution. Frac port sleeves, having no ball present after initial completion operations, may be closed with a modified Otis-B coiled tubing tool should the need arrive to shut off a gas or water zone or perform a full well recompletion operation. Sleeves may also be locked in the open position, if desired.
The Sleeves can be closed and re-opened by the «Flex» Shifting tool.
