Squeeze Packer and Method of Setting a Squeeze Packer

A method of injecting a fluid into a wellbore of an oil, gas or water well through an elongate member, the method comprising:

• deploying a squeeze packer into the wellbore, the squeeze packer comprising:
• a body with a bore, at least one anchoring member actuable between active and inactive configurations in response to changes in fluid pressure, and wherein in the active configuration, the anchoring member is adapted to anchor the body in the wellbore to resist axial movement of the body in the wellbore, and a sealing member adapted to seal an annulus between the body and an inner surface of the wellbore;
• a stinger adapted for connection to the elongate member for injection of a fluid through the packer, the stinger being releasably latched onto the body;
• and
• a valve selectively actuable to open and close the bore to allow and prevent fluid passage through the body wherein the valve controls passage of pressurised fluid to the anchoring member to actuate the anchoring member between inactive and active configurations;
• the method including:
• anchoring the squeeze packer in the wellbore and sealing the annulus between the body and the inner surface of the wellbore;
• releasing the stinger froom the packer by rotation of the elongate member in a direction opposite to the direction of rotation used to disconnect the threaded couplings making up the elongate member, and
• moving the stinger axially within the body to actuate the valve between different actuation configurations.

A squeeze packer assembly for deployment in a wellbore of an oil, gas or water well on an elongate member, the squeeze packer assembly comprising

• a body having a bore, at least one anchoring member actuable between active and inactive configurations in response to changes in fluid pressure, and wherein in the active configuration, the anchoring member is adapted to anchor the body in the wellbore to resist axial movement of the body in the wellbore, and a sealing member adapted to seal an annulus between the body and an inner surface of the wellbore;
• a stinger adapted for connection to the elongate member for injection of a fluid through the body;
• a latch adapted to releasably latch the stinger onto the body;
• and
• a valve selectively actuable to open and close the bore to allow and prevent fluid passage through the body, wherein the valve controls passage of pressurised fluid to the anchoring member to actuate the anchoring member between inactive and active configurations, and wherein the valve is controlled by axial movement of the stinger and the elongate member relative to the body to actuate the valve between different actuation configurations;
• wherein the stinger is connected to the body by a threaded connection, wherein the thread is connected by anti-clockwise rotation of the stinger with respect to the body and is disconnected by clockwise rotation of the stinger with respect to the body, and wherein the stinger is adapted to be disconnected from the body by clockwise rotation relative to the body,
• wherein the valve has a seat disposed in the bore and wherein seating a valve closure member on the seat sets the anchoring member by hydraulic pressure diverted through the bore of the body by the valve closure member on the seat;
• and
• wherein the sealing member is expanded in the annulus between the body and an inner surface of the welibore to seal the annulus by pulling up on the elongate member.
