Abstract
An apparatus and technique for use in spacing out tubular strings within a well includes a casing that has an inner wall and at least one profile that is disposed within the inner wall. A tubing hanger is attached to the well tubing and if capable of landing within a target location, such as a wellhead. When the landing tool is seated within the profile, the length of well tubing needed to land the tubing hanger within the target location can be determined. A landing tool is linked to well tubing and is sized so as to seat within the profile.
Claims43
A system for use in spacing components within a wellbore, comprising:
- a well casing comprising at least one profile, the profile capable of being positioned at a known location within the wellbore and adapted to indicate a location of at least one component inserted into the wellbore so that an adjustment to the length of a tubular string attached to said at least one component can be determined to enable landing of a tubing hanger.
An apparatus for use in spacing out tubular strings within a well comprising:
- a casing having an inner wall, the casing comprising at least one profile disposed within the inner wall;
- a landing tool that is linked to well tubing and is sized so as to seat within the at least one profile;
- a tubing hanger attached to the well tubing, the tubing hanger capable of landing within a target location;
- and
- wherein when the landing tool is seated within the at least one profile, the length of well tubing needed to land the tubing hanger within the target location can be determined.
An apparatus for use in spacing out tubular strings within a well comprising:
- a casing having an inner wall, the casing comprising an upper profile and a lower profile;
- well tubing that is movable longitudinally within the casing;
- and
- a landing tool that is linked to the well tubing and that comprises seating projections adapted to sequentially seat in the upper profile and the lower profile.
A method of spacing components within usable with a wellbore, comprising:
- providing a well casing comprising at least one profile;
- inserting at least one component within the wellbore, wherein at least one component can releasably engage with the at least one profile;
- observing the effects of the engagement of at least one component with the at least one profile;
- and
- in response to the observation, determining a length of tubing required to obtain desired placement of well equipment attached to the tubing within the wellbore.
A method of spacing out a tubular string within a well having a wellhead comprising:
- providing a casing string located within the well, the casing string having an inner wall and at least one profile within the casing inner wall, the at least one profile including an upper profile, and the at least one profile being located at known distances apart from each other and from the wellhead;
- inserting a tubular string linked to a landing tool into the well;
- seating the landing tool within the upper profile;
- and
- in response to the seating, determining the correct tubular length required to properly space out the well.
A method of spacing out a tubing string within a wellhead of an offshore well comprising:
- providing a casing string having a first profile;
- inserting a tubing string within the well having a landing tool that can engage with the first profile;
- inserting the tubing string until the landing tool engages with the first profile;
- determining the length of tubing string needed for proper tubing space out;
- disengaging the landing tool from the first profile;
- altering the tubing string to achieve a predetermined length;
- attaching a tubing hanger to the tubing string;
- and
- inserting the tubing string to the depth where the tubing hanger is properly positioned within the wellhead.
A method of completing a well, comprising:
- providing a well casing comprising at least one profile on its inner wall;
- inserting the well casing within a wellbore comprising at least one lateral wellbore;
- inserting at least one component within the wellbore on a tubular string, the at least one component comprising at least one landing tool that can releasably engage with the at least one profile;
- observing the effects of the engagement of at least one landing tool with the at least one profile;
- and
- in response to the observation, determining the amount of tubular string movement required to obtain a desired component placement within the wellbore.
A method of completing a well, comprising:
- providing a well casing comprising at least one profile on its inner wall;
- inserting the well casing into a wellbore, the wellbore comprising at least one lateral wellbore;
- inserting at least one landing tool that can releasably engage with the at least one profile into the wellbore on a tubular string, the at least one landing tool comprising at least one lower tubing string capable of extending from the at least one landing tool;
- observing the effects of the engagement of at least one landing tool with the at least one profile;
- determining the amount of tubular string movement required to obtain a desired component placement within the wellbore, the desired component placement comprising the landing of a tubing hanger within a wellhead;
- extending at least one lower tubing string from the landing tool into at least one lateral wellbore.
