In resource recovery arts, it is often desirable to filter produced fluids emanating from formations that bear them. To this end, sand screens are common in the industry. Sand screens commonly include a base pipe with ribs longitudinally disposed there around and a wire rapped about the ribs. In order to ensure the wire stays where placed, end rings are commonly disposed at the termination of the screen jacket and welded in place. While the method works well, it requires manpower and processes that amount to cost in production.
Greater efficiency is always welcomed where viable products can be attained and so the art is always receptive to new methods and apparatus that achieve that result.
A screen jacket termination configuration including a base pipe, a rib disposed at the base pipe, a wire wrapped about the base pipe and rib to form a screen jacket, and a termination strip wrapped about the base pipe and rib and disposed between wraps of the wire.
A screen jacket termination configuration including a base pipe, a rib disposed at the base pipe, a wire wrapped about the base pipe and rib to form a screen jacket, the wire having a first gap from the base pipe and being gradually reduced in a dimension of the gap from the base pipe from a more central position on the screen jacket to an end of the screen jacket.
A method for terminating a screen jacket includes disposing a termination strip between adjacent wraps of a screen jacket, the termination strip closing a space between the screen jacket and a base pipe at an end of the screen jacket such that any gap between the termination strip and the base pipe is less than a gauge of the screen jacket.
The following descriptions should not be considered limiting in any way. With reference to the accompanying drawings, like elements are numbered alike:

Set forth below are some embodiments of the foregoing disclosure:
A screen jacket termination configuration including a base pipe, a rib disposed at the base pipe, a wire wrapped about the base pipe and rib to form a screen jacket, and a termination strip wrapped about the base pipe and rib and disposed between wraps of the wire.
The configuration as in any prior embodiment, wherein the termination strip comprises a web.
The configuration as in any prior embodiment, wherein the termination strip comprises a web and a flange.
The configuration as in any prior embodiment, wherein the web and flange are at included angle in a range of 80 to 100 degrees.
The configuration as in any prior embodiment, wherein a proximity between the termination strip and the base pipe ranges between contact and a gap not exceeding a selected gauge for the screen jacket.
The configuration as in any prior embodiment, wherein the termination strip is welded to the rib.
The configuration as in any prior embodiment, wherein the termination strip is welded to the wire of the screen jacket.
The configuration as in any prior embodiment, wherein the termination strip includes a flange welded to the wire of the screen jacket.
A screen jacket termination configuration including a base pipe, a rib disposed at the base pipe, a wire wrapped about the base pipe and rib to form a screen jacket, the wire having a first gap from the base pipe and being gradually reduced in a dimension of the gap from the base pipe from a more central position on the screen jacket to an end of the screen jacket.
The configuration a as in any prior embodiment, wherein the end of the screen jacket is defined by the wire-to-base pipe gap being no more than a gauge of the screen jacket.
The configuration as in any prior embodiment, wherein the reduced distance is by deeper fusing of the wire with the rib.
A method for terminating a screen jacket includes disposing a termination strip between adjacent wraps of a screen jacket, the termination strip closing a space between the screen jacket and a base pipe at an end of the screen jacket such that any gap between the termination strip and the base pipe is less than a gauge of the screen jacket.
The method as in any prior embodiment, further including welding the termination strip to the screen jacket.
A method for terminating a screen jacket including gradually reducing a gap between a wire wrap of the screen jacket and a base pipe until the dimension of the gap is no greater than a gauge of the screen jacket.
The method as in any prior embodiment, wherein the reducing is by more deeply fusing the wire to a rib.
The use of the terms “a” and “an” and “the” and similar referents in the context of describing the invention (especially in the context of the following claims) are to be construed to cover both the singular and the plural, unless otherwise indicated herein or clearly contradicted by context. Further, it should be noted that the terms “first,” “second,” and the like herein do not denote any order, quantity, or importance, but rather are used to distinguish one element from another. The modifier “about” used in connection with a quantity is inclusive of the stated value and has the meaning dictated by the context (e.g., it includes the degree of error associated with measurement of the particular quantity).
The teachings of the present disclosure may be used in a variety of well operations. These operations may involve using one or more treatment agents to treat a formation, the fluids resident in a formation, a wellbore, and/or equipment in the wellbore, such as production tubing. The treatment agents may be in the form of liquids, gases, solids, semi-solids, and mixtures thereof. Illustrative treatment agents include, but are not limited to, fracturing fluids, acids, steam, water, brine, anti-corrosion agents, cement, permeability modifiers, drilling muds, emulsifiers, demulsifiers, tracers, flow improvers etc. Illustrative well operations include, but are not limited to, hydraulic fracturing, stimulation, tracer injection, cleaning, acidizing, steam injection, water flooding, cementing, etc.
While the invention has been described with reference to an exemplary embodiment or embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiment disclosed as the best mode contemplated for carrying out this invention, but that the invention will include all embodiments falling within the scope of the claims. Also, in the drawings and the description, there have been disclosed exemplary embodiments of the invention and, although specific terms may have been employed, they are unless otherwise stated used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention therefore not being so limited.
