Halliburton recently announced that two of its RapidStart Initiator CT (casing test) sleeves opened after 32 months downhole. That time period represents an industry record for the successful operation of a toe sleeve, according to the company. Murphy E&P needed to perform a true casing integrity test and had deployed the RapidStart Initiator CT frac sleeve system as an interventionless means of establishing a flow path at the toe of the well. Both sleeves opened successfully after 32 months downhole in two drilled but uncompleted (DUC) wells of more than 7,000 ft, with static bottomhole temperatures up to 215˚F. The sleeves were functional at a total pressure of 10,000 psi and provided a 30-min casing integrity test.
