Description
- In the resource exploration and recovery industry, wellbores are formed in a formation for the purpose of discovering and exploiting formation fluids. Generally, a tubular is run into the wellbore for the purpose of delivering formation fluids to a surface system for processing, transportation and/or storage. Often times, the formation fluids pass into the tubular through a screen assembly. The screen assembly may take on various forms and could include any number of layers. The screen assembly provides passage into the tubular for desirable fluids while, at the same time, excluding undesirable fluids and/or solids.
- In certain cases, the screen assembly is formed by wrapping a wire around an outside of a tubular. Wire size, wire spacing, and wire geometry may all be selected to meet various design constraints. Generally, sections of wire wrap are applied to the tubular. In between the sections of wire wrap, a gauge ring may be installed. The gauge ring is secured to the outer surface of the tubular and establishes a desired positioning or centering of the tubular in the wellbore.
- Installing gauge rings is a time consuming process. A first section of wire wrap is applied to the tubular. After the first portion, the gauge ring is installed. At this point, a subsequent portion of wire wrap is installed. The need to switch between processes, e.g., wrapping wire, and wrapping gauge rings, increases the time and costs needed to form a screen assembly. Also, the need to switch processes can result in an increase in scrap if a wire spool does not have enough remaining material to form a section. The art would be open to new methods of forming screen assemblies that are less time consuming, require fewer set up steps, and result in eliminating scrap wire.
- Disclosed is a screen assembly for subsurface systems including a tubular having an outer surface. A first screen portion and a second screen portion extend about the outer surface. The second screen portion is displaced from the first screen portion by a void region. A plurality of weld plugs is mounted about the outer surface of the tubular in the void region. A centralizing ring extends about the tubular at the void region. The centralizing ring extending over each of the first screen portion and the second screen portion and is mechanically joined to the tubular through the plurality of weld plugs.
- Also disclosed is a method of forming a screen assembly including positioning a first screen portion about an outer surface of a tubular, positioning a second screen portion about the outer surface separated from the first screen portion by a void region, mounting a plurality of weld plugs about the outer surface of the tubular at the void region, positioning a centralizing ring about the tubular over the first screen portion and the second screen portion, and securing the centralizing ring to the tubular through the plurality of weld plugs.
- Further disclosed is a resource exploration and recovery system including a first system, and a second system connected to the first system through a tubular system supporting a screen assembly including a tubular having an outer surface. A first screen portion and a second screen portion extend about the outer surface. The second screen portion is displaced from the first screen portion by a void region. A plurality of weld plugs is mounted about the outer surface of the tubular in the void region. A centralizing ring extends about the tubular at the void region. The centralizing ring extends over each of the first screen portion and the second screen portion and is mechanically joined to the tubular through the plurality of weld plugs.
