Description
- Tubular systems often have multiple openings through which fluid can flow and thereby commingle with fluid already flowing within the tubular. Regardless of where such flow enters the tubular it may be beneficial for an operator to know whether or not fluid is flowing through a particular portion of the tubular. Positioning flow measuring devices and the telemetry to communicate readings from the flow measuring devices though effective may be overly complex for some applications. Simple systems and methods that allow one to determine such things are therefore of interest to those who practice in the art.
- Disclosed herein is a fluid flow location identification positioning system. The system includes, at least one component that is attachable within a tubular at any user selectable location within the tubular, and an identifier in operable communication with the at least one component configured to be eroded by fluid that flows therepast, at least trace amounts of the identifier are releasable into fluid that erodes the identifier.
- Further disclosed herein is a method of detecting flow in a tubular. The method includes, positioning an identifier at any location within a tubular, flowing fluid through the tubular past the identifier, eroding the identifier, and detecting at least trace amounts of the identifier in fluid downstream of the location.
- Further disclosed herein is a method of treating a formation. The method includes, setting a frac plug or bridge plug within a tubular, plugging the frac plug or bridge plug with a plug, treating a formation upstream of the plugged frac plug or bridge plug, removing the plug, producing fluid through the frac plug or bridge plug, eroding an identifier positioned at the frac plug or bridge plug with fluid flowing therepast, and detecting at least trace amounts of the identifier in fluid downstream of the frac plug or bridge plug.
- The following descriptions should not be considered limiting in any way. With reference to the accompanying drawings, like elements are numbered alike:
-
FIG. 1 depicts a partial side cross sectional schematic view of a fluid flow location identification positioning system disclose herein; and -
FIG. 2 depicts a side cross sectional view of a frac plug or bridge plug employable in the fluid flow location identification positioning system ofFIG. 1 . - 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 an embodiment of a fluid flow location identification positioning system disclosed herein is illustrated at 10. Thesystem 10 includes, at least onecomponent selectable locations selected locations system 10 also includes at least oneidentifier components identifiers trace amounts identifiers identifiers trace amounts identifiers identifiers locations identifiers - Concentrations of the
identifiers identifiers identifiers downstream location 42. By making theidentifiers fluid flow rates 44, 48 past each of theidentifiers 24, 28 (and thus past thelocations 18, 20) can determined separately. If, for example, in the illustrated embodiment with just the twoidentifiers trace amounts downstream location 42 were identical then thefluid flow rates 44, 48 must be the same. Or, stated another way, there must be no additional fluid flow being introduced to the tubular 22 between thefirst location 18 and thesecond location 20. - If, in another scenario however, measurements taken at the
downstream location 42 reveal that the concentration of thefirst identifier 24 is half the concentration of thesecond identifier 28 it can be determined that the fluid flow rate 44 is half of thefluid flow rate 48. Then it is a simple matter to proportion thetotal flow rate 50 at thedownstream location 42 according to the proportions flowing by each of thelocations - Referring to
FIG. 2 , an embodiment of a plug such as a frac plug or bridge plug, for example, employable within the fluid flow locationidentification positioning system 10 is illustrated at 60. Thefrac plug 60 is settable within the tubular 22, shown in this embodiment as an open hole (although the tubular can be a casing or liner as illustrated inFIG. 1 ), within a borehole 64 in anearth formation 68 in a hydrocarbon recovery or carbon dioxide sequestration application, for example. Thefrac plug 60 hasslips 72 that can anchor thefrac plug 60 to the tubular 22 in response to radially expanding while being axially moved relative to acone 76. Aseal 80 is also radially expandable into sealing engagement with the tubular 22 in response to being axially moved relative to thecone 76 or relative to asecond cone 84. Anoptional retainer 88 can hold theslips 72 engaged with the tubular 22 by preventing axial movement of theslips 72 in the opposite direction than the direction that caused theslips 72 to radially expand. It should be appreciated that thisfrac plug 60 can be positioned anywhere along the tubular 22 since no features are required within the tubular 22 for setting of thefrac plug 60 within the tubular 22. The frac plug also 60 includes aseat 92 that can be sealed by aplug 96 run thereagainst. Once theplug 96 is seated pressure can build upstream of theplug 96 to allow for treating, such as acidizing, for example or fracturing of theformation 68. - The
frac plug 60 provides a platform for positioning theidentifiers locations identifiers frac plug 60 as is shown in the illustrated embodiment by aradially groove 98. Alternatively, theidentifiers slips 72, thecones seal 80 or theretainer 88, or other component of thefrac plug 60. For example, theidentifiers screws 100, shear screws and rings, and locking rings (not shown), to name a few. In another embodiment the identifier can be integrally incorporated into one or more of thecomponents more components - The embodiment of the
frac plug 60 illustrated herein has a smallestradial dimension 102 that is quite large in comparison to aradial dimension 106 ofwalls 110 of the tubular 22. The ratio of the smallestradial dimension 102 to theradial dimension 106 of thewalls 110 may be set to be within the range of about 70 to 80 percent. The large flow area through thefrac plug 60 allows for significant flow rates through thefrac plug 60 while creating little restriction. As such, hydrocarbon recovery applications, for example, can leave thefrac plug 60 in place within the tubular 22 while producing hydrocarbons therethrough. In fact, thefrac plug 60 can remain within the tubular 22 for the life of the well thereby negating any loss of production that might result during any downtime of the well while thefrac plug 60 is milled or drilled out from within the tubular 22. - Regardless of where specifically the
