Abstract
A technique facilitates downhole operations, e.g. gravel packing and cementing operations, in a borehole. According to an embodiment, a service tool is releasably coupled with respect to a casing. The casing is used to run the service tool downhole into a borehole. In some embodiments, the casing is connected with a downhole completion, e.g. a sand control completion. A work string may then be conveyed downhole to the service tool and connected to the service tool. While connected to the work string, the service tool may be operated to perform desired downhole operations.
Claims16
A method for use in a well, comprising:
- releasably coupling a service tool within a casing;
- running the service tool via the casing downhole into a wellbore;
- positioning a sand control completion coupled to the casing at a downhole location for gravel packing;
- conveying a work string downhole to the service tool after positioning the sand control completion at the downhole location;
- connecting the work string to the service tool via a latch at a lower end of the work string;
- and
- using the service tool while connected to the work string to perform downhole operations the downhole operations including:
- pumping a gravel slurry through the work string, the latch, and the service tool;
- and
- pumping cement through the work string, the latch, and the service tool.
A method, comprising:
- coupling a sand control completion with casing;
- conveying a service tool downhole into a borehole with the sand control completion via the casing;
- positioning the sand control completion at a downhole location for gravel packing;
- subsequently connecting the service tool with a work string via a latch at a lower end of the work string;
- and
- using the service tool downhole to perform downhole operations, the downhole operations including:
- opening a gravel pack sleeve assembly of the sand control completion using a shifter of the service tool;
- and
- pumping a gravel slurry through the work string, the latch, the service tool, and the gravel pack sleeve assembly.
A system, comprising:
- a service tool positioned downhole via casing, the service tool having:
- a latch profile;
- a circulation assembly below the latch profile;
- and
- one or more shifters below the circulation assembly, the one or more shifters configured to open a gravel pack sleeve;
- and
- a work string having a latch which is latchable into the latch profile after the service tool is positioned downhole.
