  • Apparatus and method for abrasive perforating and cleanout
    Patent number: 9115558
    Abstract: An apparatus and a method of performing a plurality of operations in a wellbore with one direction of flow. A multicycle open/close valve (MCOCV) responsive to a plurality of flow rates is placed in a bottom hole assembly (BHA) and is used to perform abrasive perforating of a wellbore or cleanout of the wellbore using one direction of flow. At one or more first flow rates, the MCOCV is configured to operate in a first operating mode to abrasive perforate the wellbore. At one or more second flow rates, the MCOCV is configured to operate in a second operating mode to cleanout the wellbore. In an embodiment, the MCOCV includes a J-slot sequencing mechanism responsive to a sequence of flow rates to cycle the MCOCV through a plurality of operating modes.

  • APPARATUS AND METHOD FOR ABRASIVE PERFORATING AND CLEANOUT USING A MULTI-CYCLE OPEN/CLOSE VALVE
    Publication number: 20120205108
    Abstract: There is disclosed an apparatus and a method of performing a plurality of operations in a wellbore with one direction of flow. In an illustrative example, a multicycle open/close valve (MCOCV) responsive to a plurality of flow rates is placed in a bottom hole assembly (BHA) and is used to perform abrasive perforating of a wellbore or cleanout of the wellbore using one direction of flow. At one or more first flow rates, the MCOCV is configured to operate in a first operating mode to abrasive perforate the wellbore. At one or more second flow rates, the MCOCV is configured to operate in a second operating mode to cleanout the wellbore. In an embodiment, the MCOCV includes a J-slot sequencing mechanism responsive to a sequence of flow rates to cycle the MCOCV through a plurality of operating modes.
