Patent Application
20230145431
In the resource recovery and fluid sequestration industries, there is need for signal conduction, sensory, and actuation operations in a downhole environment. One of the operational interests for such activity is the ability to spool a conductor that includes modules for various purposes. The art has struggled with spooling modules that inevitably are relatively long and relatively rigid. Such constructions inherently do not spool well. The art would therefore well receive alternatives that improve spoolability of modules that are needed in the downhole environment.
An embodiment of a spoolable device including a first communication interface, a second communication interface, a power management module, a functional electrical module, and a junction joining each of the above elements together and creating a shared pressure chamber.
An embodiment of a method for making a spoolable device comprising welding a functional electrical module to a first portion of a junction box, welding a first communication interface to the first portion of a junction box, welding a power management module to a second portion of a junction box, welding a second communication interface to the second portion of a junction box, and welding the first portion of a junction box to the second portion of the junction box to form a pressure chamber inside the first and second portions of the junction box.
A borehole system including a borehole in a subsurface formation, a string in the borehole, and a device disposed within or as a part of the string.
The following descriptions should not be considered limiting in any way. With reference to the accompanying drawings, like elements are numbered alike:
A detailed description of one or more embodiments of the disclosed apparatus and method are presented herein by way of exemplification and not limitation with reference to the Figures.
Referring to
The device 10 is made in the following sequence. Referring to
Following the foregoing, another half of the device 10 is constructed in a similar manner. A junction box adapter 40 that will be a part of the interface 12 is welded to junction box 42 in another rotary process for example. A junction box adapter 44 is welded to a cable head 46 in
Various welding processes mentioned herein include rotary welding or face welding and may employ an electron beam process, a laser weld process or other fusing process that is capable of controlling heat affected zone such that internal electronic components are not damaged. Further, it is contemplated that all description of “welding” may be substituted, in embodiments, by alternate means of bonding, whether chemical or mechanical providing a pressure vessel is created and electronics therein are not damaged. In such a way, the benefit of this disclosure, superior spoolability, may still be reaped. Further, it is to be appreciated that while only one device 10 is illustrated, more than one is contemplated on a conductor. Signals being borne by a conductor may be passed through one or more devices 10. A plurality of devices 10 may be disposed along a conductor evenly or unevenly as is desired and practicable for the end purpose of each device 10. For example, perhaps one device 10 will connect to a first type of actuator for a packer for example, while a second device 10 might connect to a valve, etc.
Referring to

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 terms “about”, “substantially” and “generally” are intended to include the degree of error associated with measurement of the particular quantity based upon the equipment available at the time of filing the application. For example, “about” and/or “substantially” and/or “generally” can include a range of ±8% or 5%, or 2% of a given value.
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.
