Description

BACKGROUND

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.

DETAILED DESCRIPTION

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 FIG. 1 , a first embodiment of a borehole tool 10 is illustrated. Tool 10 is a screen tool and comprises a unitary single-piece basepipe 12. It is to be appreciated that the terms “unitary, single-piece” are meant to convey a piece of material that is contiguous, having no welded joints therein nor threaded joints therein nor interference joints therein nor bonded joints therein. There are no joints but rather the unitary single-piece basepipe disclosed herein is of a single piece of material that may be a steel material and does not include multiple pieces fused together in any way to make up the unitary single-piece basepipe. Such basepipes having forms dictated by a customer are commercially available from Vallourec.
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.
Referring to FIG. 2-4 sequentially, the making of the borehole tool is clarified. FIG. 3 illustrated the basepipe 12 having the radially larger features 14, 16 and 26. Between these is the intermediate portion 18, which is bisected in this illustration by upset 26. Holes 30 are easily appreciated and will provide the fluid pathway from the filtration media to an inside diameter 40 (identified in FIG. 1 ) of the basepipe 12. Recesses 38 are also easily appreciated and will accept ribs 36 as can be seen in FIG. 3 . In FIG. 4 , the wire 36 has been installed and it can be easily viewed that the screen surface is of a smaller outer diameter than the end portions 14 and 16 and the upset 26. This protects the screen during run in.
In an alternate embodiment, referring to FIG. 5 , a borehole tool 50 is illustrated in cross section. The tool 50 is a seal tool and comprises a basepipe 52 having end portions 54 and 56 that are of greater outside diameter than an intermediate portion 58. The basepipe 52 is again a unitary, single-piece structure as defined above and is available from Vallourec. In this embodiment, an element 60 is disposed about the basepipe 52 that in a first condition (running condition) has an outside diameter that is less than an outside diameter of the end portions 54 and 56 of the basepipe 52 and in a deployed condition will have a larger outside diameter than that of its running condition including larger than the end portions 54 and 56. Element 60 may be a compression element, (with suitable compression components adjacent the element) and about intermediate portion 58, may be a swellable element, a shape memory element, an inflatable element (with suitable inflation components connected to the inflatable element), etc. Those of skill in the art will recognize the types of elements and understand the ways in which such elements are traditionally actuated such that no specific teaching is herein needed. In embodiments, two or more elements and or screens may be employed on a basepipe. Any number of upsets like 26 are contemplated with any combination of screens and elements thereon. For example, on a basepipe with a three part intermediate portion and two upsets 26, there may be an element and then a screen and then another element; or a screen then element then screen; or screen, screen, screen; or element, element, element. The reader should appreciate the possibilities from the foregoing. Some examples are included in FIGS. 6-9 using two screens and/or elements. More or fewer are contemplated as disclosed above.
Referring to FIG. 10 , a borehole system 70. The system 70 includes the borehole 72 that extends within a subsurface formation 74. A string 76 is disposed within the borehole 72. Disposed within or as a part of the string 76 is an object 10, 50 as disclosed herein.
