Leaking DV Tool Repair
After a Staged-cementing job is complete, it may not be possible to close the Stage tool or differential valve (DV) tool. Should this occur, the optimum solution would be to set a Saltel patch across the ports to seal off the open port. If this is to be Frac’d, the Saltel patch provides a minimal loss of ID, in fact Saltel Industries guarantees the largest ID in the industry across a milled port. This being the case the Operator is able to Frac with sometimes losing NO stages. Once the well is Frac’d the patch has served its purpose and can be perforated to eliminate any possibility of collapse during flow-back.
