Patent Application
20230160285
In the resource recovery and fluid sequestration industries screens are often needed to filter fluid so that particulates do not end up where they could do damage or reduce efficiency. Oftentimes, screens are put in place in separate runs from a primary run that creates an opportunity to use a screen. Runs are expensive and hence reducing the number of runs is desirable. Single or multiple borehole tools that restrict or stop annulus flow during production and/or injection are often a necessity to have on the same run as screens. The isolation tool, often referred to as zonal isolation, limits or prevent fluid moving along the screen surface in the borehole outside the screen. Screens and zonal isolation however are generally somewhat delicate and subject to damage if run before an optimal running situation is completed. Screens and zonal isolation that are robust enough to be deployed using fewer runs and/or robust enough to enable reaching bottom of hole in rough conditions would be well received by the art.
An embodiment of a borehole tool including a unitary, single-piece basepipe having a first end portion, a second end portion, and an intermediate portion extending between the first end portion and the second end portion, the first and second end portions being of larger diameter than the intermediate portion, an operational member having a first end and a second end, the member disposed about the basepipe, the first end of the member nearer the first end portion than the second end portion and the second end of the member nearer the second end portion than the first end portion, the member having an outside diameter no greater than the first end portion and the second end portion.
A method for making a screen including wrapping a wire around the basepipe, and forming the filtration media with the wire.
An embodiment of a borehole system including a borehole in a subsurface formation, a string disposed in the borehole, and a tool 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 basepipe 12 includes a first end portion 14, a second end portion 16 and an intermediate portion 18. The end portions 14 and 16 may each abut a diameter change portion 20 and 22, respectively. In embodiments, there may also be one or more additional portions that increase the outer diameter of the intermediate portion 18, such as upset 26. Upset 26 may have an outer diameter that is the same as the outer diameter or end portions 14 and 16 or may have a different outer diameter, smaller or larger.
In one embodiment, where an operational member 28 having a first end 29 (49 in the second embodiment) and a second end 31 (51 in the second embodiment) associated with the basepipe 12 is a filtration media, radially directed holes 30 are created in the basepipe 12. About the basepipe 12 and radially outwardly of the holes 30 is a screen 32. The screen may in some embodiments be configured from a wrapped wire 34. Wire 34 is wound around the basepipe 12 in a manner known to the art and may be secured with welds or similar affixation. In some embodiments, one or more ribs 36 are longitudinally disposed on the basepipe 12 either as formed portions of the basepipe 12 or as separate ribs 36 that are disposed in recesses 38 that are formed or milled in the basepipe 12, or as separate ribs 36 that are temporarily fixtured to the basepipe prior to wrapping wire 34, including without recesses 38 in some embodiments. The wire 34 may be welded to each rib 36 and is under tension when wrapped, which provides securement of the screen 32 to the basepipe 12.
