Abstract
A fitting arrangement and method of securing a fitting arrangement to a surface is provided. A plurality of adjacent fittings is coupled to and extends from a mounting surface of a structure in a well bore. Each fitting has an engagement surface that is configured to engage with an installation tool for coupling the fitting to the structure. The engagement surfaces of the adjacent fittings in the plurality are offset from each other to thereby define a clearance for the installation tool.
Claims25
A fitting arrangement for installation in a well bore, the fitting arrangement comprising:
- a plurality of fittings coupled to and extending axially from a mounting surface in the well bore, wherein each of the fittings are configured to create a seal between a control line and the mounting surface;
- and
- an engagement surface on each of the fittings, the engagement surface configured to engage with an installation tool for coupling the fitting to the mounting surface;
- the engagement surface of adjacent fittings in the plurality being axially offset from each other to thereby define an access clearance for the installation tool.
A fitting arrangement for installation in a well bore, the fitting arrangement comprising:
- a packer disposed in the well bore;
- a plurality of fittings coupled to and extending axially from a surface of the packer, each of the fittings defining a passageway into the packer;
- a control line extending into each of the fittings;
- an engagement surface on each fitting, the engagement surface configured to engage with an installation tool for coupling the fitting to the packer;
- the engagement surface of adjacent fittings in the plurality being axially offset from each other to thereby define an access clearance for the installation tool.
A method of securing a fitting arrangement to a packer in a well bore, the method comprising the steps of:
- providing a packer configured to seal with a well tubing string;
- providing a plurality of axially elongated fittings, each of the fittings having engagement surfaces for engaging with an installation tool;
- coupling each of the fittings to adjacent locations on mounting surface of the packer by engaging the respective engagement surfaces with an installation tool, wherein when the fittings are coupled to the packer, the engagement surfaces of adjacent fittings in the plurality are offset from each other in the axial direction to define an access clearance for an installation tool;
- threading a control line through each of the plurality of fittings;
- and
- inserting the well tubing string, packer and plurality of fittings into the well bore.
