  • Interruptible pressure testing valve
    Patent number: 9334710
    Abstract: A wellbore servicing system comprising a pressure testing valve incorporated within a casing string and comprising a housing comprising one or more ports and an axial flowbore, a sliding sleeve, wherein the sliding sleeve is positioned within the housing and transitional from a first position to a second position through a sliding sleeve stroke, wherein, in the first position, the sliding sleeve blocks a route of fluid communication via the one or more ports and, in the second position the sliding sleeve does not block the route of fluid communication via the one or more ports, wherein the pressure testing valve is configured such that application of a predetermined pressure to the axial flowbore for a predetermined duration causes the sliding sleeve to transition from the first position to the second position, wherein the predetermined duration is at least about one minute.
