Abstract
A system for treating a formation of a borehole having casing has a sleeve, a motor, and a packer. The sleeve is disposed on the casing in the borehole and has a port communicating out of the sleeve. An insert disposed in the sleeve is movable in the sleeve from closed to opened position relative to the port. The motor is deployed in the casing with coiled tubing and is operable to impart rotation. The packer is operatively coupled to the motor. In response to the rotation imparted by the motor, the packer sets in the insert of the sleeve and moves the insert to the opened condition.
Claims25
A system using coiled tubing for treating a formation of a borehole having casing, the system comprising:
- at least one sleeve disposed on the casing in the borehole, the at least one sleeve having at least one port communicating outside the at least one sleeve and having an insert disposed in the at least one sleeve, the insert movable in the at least one sleeve at least from a closed position to an opened position relative to the at least one port;
- a motor deployed in the casing with the coiled tubing and being operable to impart rotation;
- and
- a packer operatively coupled to the motor, the packer, in response to the rotation imparted by the motor, engaging in the insert of the at least one sleeve and moving the insert at least to the opened condition.
A sleeve for fluid communication on tubing, the sleeve comprising:
- a housing having first and second ends coupling to the tubing and having a bore therethrough, the housing defining at least one port communicating the bore outside the housing;
- an insert disposed in the bore of the housing and being movable inside the bore at least from a closed position to an opened position relative to the at least one port;
- and
- a guide component disposed between the housing and the insert and guiding rotation and axial displacement of the insert moving from the closed position to the opened position.
A system using coiled tubing for treating a formation of a borehole through at least one sleeve disposed on casing in the borehole, the at least one sleeve having an insert disposed therein, the insert movable in the at least one sleeve at least from a closed position to an opened position relative to at least one port, the system comprising:
- a motor deployed in the casing with the coiled tubing and being operable to impart rotation;
- and
- a packer operatively coupled to the motor, the packer, in response to the rotation imparted by the motor, engaging in the insert of the at least one sleeve and moving the insert at least to the opened condition with the rotation imparted by the motor.
A method using coiled tubing for treating a formation of a borehole having casing with at least one sleeve disposed thereon, the method comprising:
- deploying a motor and a packer in the casing with the coiled tubing;
- engaging the packer in an insert of the at least one sleeve;
- imparting rotation to the packer with the motor;
- moving the insert of the at least one sleeve from a closed position to an opened position with the imparted rotation of the engaged packer;
- and
- treating the formation through at least one port of the opened sleeve.
