Definitions
- the embodiments described herein relate to a plug having a valve that permits fluid flow in both directions through the plug, but impedes or resists the flow in one direction with respect to the flow in the other direction.
- the valve permits the fracturing of a portion of a wellbore without the need to pump a plug, such as a ball, down the wellbore to block fluid flow to increase pressure within the wellbore.
- Natural resources such as gas and oil may be recovered from subterranean formations using well-known techniques.
- Wellbores both vertical and horizontal, may be drilled into a formation.
- a string of pipe e.g., casing
- Hydrocarbons may then be produced from the wellbore.
- Hydraulic fracturing of a wellbore has been used for more than 60 years to increase the flow capacity of hydrocarbons from a wellbore. Hydraulic fracturing pumps fluids into the wellbore at high pressures and pumping rates so that the rock formation of the wellbore fails and forms a fracture to increase the hydrocarbon production from the formation by providing additional pathways through which reservoir fluids being produced can flow into the wellbore.
- One method of fracturing multiple zones in a wellbore is to use multiple ported collars in combination with sliding sleeve assemblies.
- the sliding sleeves are installed on the inner diameter of the casing and/or sleeves and can be held in place by shear pins.
- the bottom most sleeve is capable of being opened hydraulically by applying a differential pressure to the sleeve assembly.
- a fracturing process is performed on the bottom most zone of the well. This process may include hydraulically sliding sleeves in the first zone to open ports and then pumping the fracturing fluid into the formation through the open ports of the first zone.
- a plug which may be a ball
- the ball hits the next sleeve up from the first fractured zone in the well and thereby opens ports for fracturing the second zone.
- a second ball which is slightly larger than the first ball, is dropped to open the ports for fracturing the third zone. This process is repeated using incrementally larger balls to open the ports in each consecutively higher zone in the well until all the zones have been fractured.
- the well diameter is limited in size and the ball sizes are typically increased in quarter inch increments, this process is limited to fracturing only about 11 or 12 zones in a well before ball sizes run out.
- the use of the sliding sleeve assemblies and the packers to set the well casing in this method can be costly. Further, the sliding sleeve assemblies and balls can significantly reduce the inner diameter of the casing, which is often undesirable. After the fracture stimulation treatment is complete, it is often necessary to mill out the balls and ball seats from the casing.
- Additional disadvantages of the current system may exist. For example, it may take a considerable amount of time to pumping a ball to down the wellbore to open the sliding sleeve of each production zone to be fractured. A system that may be used to fracture a production zone without the use of a ball may be beneficial.

Abstract
Description
- The embodiments described herein relate to a plug having a valve that permits fluid flow in both directions through the plug, but impedes or resists the flow in one direction with respect to the flow in the other direction. The valve permits the fracturing of a portion of a wellbore without the need to pump a plug, such as a ball, down the wellbore to block fluid flow to increase pressure within the wellbore.
- Natural resources such as gas and oil may be recovered from subterranean formations using well-known techniques. Wellbores, both vertical and horizontal, may be drilled into a formation. After formation of the wellbore, a string of pipe, e.g., casing, may be run or cemented into the wellbore. Hydrocarbons may then be produced from the wellbore.
- In an attempt to increase the production of hydrocarbons from the wellbore, the casing is often perforated and fracturing fluid is pumped into the wellbore to fracture the subterranean formation. Hydraulic fracturing of a wellbore has been used for more than 60 years to increase the flow capacity of hydrocarbons from a wellbore. Hydraulic fracturing pumps fluids into the wellbore at high pressures and pumping rates so that the rock formation of the wellbore fails and forms a fracture to increase the hydrocarbon production from the formation by providing additional pathways through which reservoir fluids being produced can flow into the wellbore.
- One method of fracturing multiple zones in a wellbore is to use multiple ported collars in combination with sliding sleeve assemblies. The sliding sleeves are installed on the inner diameter of the casing and/or sleeves and can be held in place by shear pins. In some designs, the bottom most sleeve is capable of being opened hydraulically by applying a differential pressure to the sleeve assembly. After the casing with ported collars is installed, a fracturing process is performed on the bottom most zone of the well. This process may include hydraulically sliding sleeves in the first zone to open ports and then pumping the fracturing fluid into the formation through the open ports of the first zone. After fracturing the first zone, a plug, which may be a ball, is dropped and/or pumped down the well. The ball hits the next sleeve up from the first fractured zone in the well and thereby opens ports for fracturing the second zone. After fracturing the second zone, a second ball, which is slightly larger than the first ball, is dropped to open the ports for fracturing the third zone. This process is repeated using incrementally larger balls to open the ports in each consecutively higher zone in the well until all the zones have been fractured. However, because the well diameter is limited in size and the ball sizes are typically increased in quarter inch increments, this process is limited to fracturing only about 11 or 12 zones in a well before ball sizes run out. In addition, the use of the sliding sleeve assemblies and the packers to set the well casing in this method can be costly. Further, the sliding sleeve assemblies and balls can significantly reduce the inner diameter of the casing, which is often undesirable. After the fracture stimulation treatment is complete, it is often necessary to mill out the balls and ball seats from the casing.
- Additional disadvantages of the current system may exist. For example, it may take a considerable amount of time to pumping a ball to down the wellbore to open the sliding sleeve of each production zone to be fractured. A system that may be used to fracture a production zone without the use of a ball may be beneficial.

FIG. 1 shows a cross-section view of one embodiment of aplug 100. Theplug 100 may be any plug or packer used to create a seal within a wellbore that permits fluid flow through the plug or packer as described herein. For example, theplug 100 may be an open wellbore packer that includes avalve 200 described herein that permits fluid flow in both direction through the packer, but impedes one direction of flow with respect to the other direction of flow. - The
plug 100 may be, but is not limited to, a frac plug used to hydraulically fracture a wellbore formation. Theplug 100, hereinafter referred to as a frac plug, includes abody 110 with a bore, internal flow path, orinner flow path 120, hereinafter referred to an internal flow path, which permits fluid to flow through thebody 110 of thefrac plug 100. Thefrac plug 100 includes avalve 200 having amain flow path 220 that is in fluid communication with theinternal flow path 120 to permit fluid to flow through thefrac plug 100 in a first direction, indicated by arrow A onFIG. 1 . Themain flow path 220 also permits fluid to flow through thefrac plug 100 in a second direction, indicated by arrow B onFIG. 1 . Thevalve 200 of thefrac plug 100 is a solid state device. As used herein, solid state device means that there are no moving parts. A moving part of a valve may fail and/or wear out due to repeated movement as the valve is repeatedly actuated. Further, debris and/or particulates within a wellbore may prevent the moving part of a valve from actuating properly, which may require the premature replacement of the valve. Thus, asolid state valve 200 may be preferred. - The
frac plug 100 may include aslips 130 andcones 140 used to secure thefrac plug 100 at a desired location within the wellbore. Theslips 130 may be configured to engage a tubular, such as casing or a production tubular, positioned within a wellbore. As discussed above, theplug 100 may also be a packer configured to be positioned in an openhole wellbore. Thefrac plug 100 may include a sealingelement 150 connected to the exterior of thebody 110. The sealingelement 150 may be actuated to create a seal between the exterior of thebody 110 and a portion of the wellbore. When set within a wellbore with the sealingelement 150 actuated, fluid may pass thefrac plug 100 only through theinternal flow path 120 of thefrac plug 100 and themain flow path 220 of thevalve 200. The number, configuration, and location of theslips 130,cones 140, and sealingelement 150 are shown for illustrative purposes and may be varied depending on the application as would be appreciated by one of ordinary skill in the art having the benefit of this disclosure. - The
valve 200 of thefrac plug 100 is configured to impede or provide higher resistance for the fluid flowing in one direction through themain bore 220 with respect to fluid flowing in the other direction through themain bore 220. For example, thevalve 200 may be a Tesla valve that is configured to provide an increase flow resistance in one direction. As shown inFIG. 1 , thevalve 200 may include a plurality ofprojections 230 positioned along themain flow path 220 through thevalve 200. Eachprojection 230 may be configured to divert at least a portion of the fluid flowing in one direction to flow into asecondary flow path 240 as shown inFIG. 2 . -
FIG. 2 shows that theleading edge 231 of each projection may be configured to divert at least a portion of fluid flowing in the second direction, indicated by arrow B, to flow into asecond flow path 240 around theprojection 230. Theprojections 230 may divert the majority of fluid flow, a substantial amount of fluid flow, or a portion of fluid flow into thesecondary flow path 240 as would be appreciated by one of ordinary skill in the art having the benefit of this disclosure. Thesecondary flow paths 240 positioned along themain flow path 220 through thevalve 200 increases the overall distance fluid flowing in the second direction B must travel to exit thevalve 200 with respect to the total distance traveled by fluid flowing in the first direction A. A substantial portion of the fluid flowing in the first direction A may travel along themain flow path 220 along the entire length of thevalve 200. Theprojections 230 may be configured to point in the same direction as the first direction A and thus, the projections may not divert the fluid flowing in the first direction A as it does to fluid flowing in the second direction B. As discussed herein, the first direction A may be fluid flowing from beneath thefrac plug 100 and the second direction B may be fluid flowing from above thefrac plug 100. The direction of theprojections 230 within thevalve 200 could be reversed if an application required increased fluid flow from below thefrac plug 100 in comparison to flow from above thefrac plug 100 as would be appreciated by one of ordinary skill in the art having the benefit of this disclosure. - The increase in total distance traveled by fluid to exit the
plug 100 in the second direction B may not be the only factor for having an increased flow resistance. For example, thesecondary flow paths 240 may be designed so that thereturn portion 241 of thesecondary flow path 240 creates turbulent flow within themain flow path 220. Thereturn portion 241 may be designed to return the fluid to themain flow path 220 at an orientation opposing the direction of flow as shown inFIG. 2 . In other words, thereturn portions 241 may be configured to turn the fluid flow against itself. The number, configuration, and location of theprojections 230,secondary flow paths 240, and returnportions 241 are for illustrative purposes only and may be varied within the scope of the disclosure as would be appreciated by one of ordinary skill in the art having the benefit of this disclosure. - The
valve 200 may be an integral part of thefrac plug 100. Alternatively, thevalve 200 may be manufactured as an insert that may be inserted into theinternal flow path 120 of thefrac plug 100.FIG. 3 shows an embodiment of avalve 200 as an insert. Thebody 210 of thevalve 200 includes amain flow path 220 that extends the length of thebody 210. Thevalve 200 includes a plurality ofprojections 230 positioned along themain flow path 220. As discussed above, the leadingedges 231 of theprojections 230 may divert a portion of fluid flowing in direction B to flow along asecondary flow path 240 around theprojection 230, which will reenter themain flow path 220 viareturn paths 240. Thereturn paths 240 may be configured to divert the flow fluid at an angle that opposes flow in the direction B through themain flow path 220, which may create turbulent flow within themain flow path 220. Fluid flowing in direction A may substantially flow through themain flow path 220 along the entire length of thevalve 200. Thevalve 200 may be made up of various materials as would be appreciated by one of ordinary skill in the art having the benefit of this disclosure. For example, thevalve 200 may be manufactured using a 3D printer. -
FIG. 4A shows an embodiment of avalve 300 as an insert with arrows indicating the flow of fluid from the first direction from opening 321 toopening 322. Thebody 310 of thevalve 300 includes amain flow path 320 that extends the length of thebody 310. Thevalve 300 includes a plurality ofprojections 330 positioned along themain flow path 320. Thevalve 300 also includes a plurality ofbranches 340 that are connected to themain flow path 320. The leadingedges 331 of eachprojections 330 may be configured to divert a portion of fluid flowing from opening 322 to opening 321 away from themain flow path 230, but not divert fluid flowing from opening 321 toopening 322. As indicated by the arrows onFIG. 4A , fluid flowing from opening 321 to opening 322 may take the shortest path through thevalve 300. -
FIG. 4B shows thevalve 300 ofFIG. 4A , but with fluid flowing from opening 322 toopening 321. The arrows onFIG. 4B indicate that the leadingedges 331 orprojections 330 divert a portion of the fluid flow into thebranches 340. Thereturn paths 341 of eachbranch 340 may be configured to change the direction of the fluid flow, which may create turbulent flow within thevalve 300. Theprojections 330 and returnflow paths 341 of thevalve 300 may be designed to impede fluid flow through thevalve 300 when flowing from opening 322 to opening 321 with respect to fluid flowing in the opposite direction. Fluid flowing from opening 321 to opening 322 may be in a first or uphole direction and fluid flowing from opening 322 to 321 may be in a second or downhole direction, as discussed herein. Thevalve 300 may be made up of various materials as would be appreciated by one of ordinary skill in the art having the benefit of this disclosure. For example, the insert may be manufactured using a 3D printer.FIG. 4A andFIG. 4B show thevalve 300 as an insert, but thevalve 300 could be integral to afrac plug 100 as would be appreciated by one of ordinary skill in the art having the benefit of this disclosure. -
FIG. 5 shows on embodiment of avalve 400 configured as an insert for afrac plug 100. Thevalve 400 is shown as an insert for illustrative purposes only and may be formed as an integral part of afrac plug 100 as would be appreciated by one of ordinary skill in the art having the benefit of this disclosure. Thevalve 400 includes a plurality of chambers or 450A, 450B, 450C, and 450D in communication with a main flow bore 420. Thecavities 450A, 450B, 450C, and 450D and the main flow bore 420 are in communication within achambers first opening 421 and asecond opening 422 in thebody 410. The 450A, 450B, 450C, and 450D, main flow bore 420,chambers first opening 421, andsecond opening 422 may be configured to increase fluid flow resistance for fluid flowing in one direction through thevalve 400 with respect to fluid flowing through thevalve 400 in the other direction. For example, thevalve 400 may impede the fluid flowing from thesecond opening 422 to thefirst opening 421 with respect to the fluid flowing from thefirst opening 421 to thesecond opening 422 as discussed herein. - The
second opening 422 may be configured to be larger in comparison to thefirst opening 421. Thelarger opening 422 in combination with the sloped interface with thefirst chamber 450A may cause the fluid flow to expand outward as it enters thechamber 450A. The outer recessedportions 452A of thechamber 450A in combination with theopening 455A may create turbulent flow within thevalve 400 thus increasing the fluid flow resistance. Theopening 455A betweenchamber 450A andchamber 450B may include an edge orprotrusion 451A that diverts fluid flowing towards thefirst opening 421, but does not divert fluid flowing toward thesecond opening 422. Likewise, the 450B, 450C, and 450D may includeother chambers 452B, 452C, and 452D also configured to cause turbulent flow. The leadingrecess portions 452B, 452C, and 452D may also divert a portion of fluid flowing towards theedges first opening 421, but not divert fluid flowing towards thesecond opening 422. The narrowmain flow path 420 in combination with the smaller diameter of thefirst opening 421 may tend to form a smooth narrow flow of fluid flowing towards thesecond opening 422 as it enters the valve thevalve 400 from thefirst opening 421. The smooth narrow flow of fluid may pass through the 455A, 455B, 455C, and 455D without substantial turbulence. Thus, theopenings valve 400 may provide for fluid flow in both directions through thevalve 400, but with one direction having a higher fluid flow resistance. -
FIG. 6 shows a horizontal wellbore 1 with three frac plugs 100A, 100B, and 100C positioned at different locations along the wellbore 1. Each frac plug 100A, 100B, and 100C has created a seal between the frac plug 100A, 100B, and 100C and thecasing 6 of the wellbore 1. As discussed herein, the frac plugs 100A, 100B, and 100C each include avalve 200 that permits fluid to flow through abore 120 of the frac plug 100A, 100B, and 100C and through amain flow path 220 of thevalve 200 of the 100A, 100B, and 100C. Thevalve 200 is configured to permit fluid to flow down through the frac plug, but the flow in the downward direction will have a great resistance in the flow in the upward direction through the frac plug as discussed herein. - A first frac plug 100A is positioned below a first set of perforations 10A in the
casing 6. Likewise, a second frac plug 100B is positioned below a second set of perforations 10B in thecasing 6 and a third frac plug 100C is positioned below a third set of perforations 10C in thecasing 6. Fluid may be pumped down the wellbore with the frac plugs 100A, 100B, and 100C in place to hydraulically fracture the wellbore formation 5 adjacent each of the perforations 10A, 10B, and 10C. - The higher resistance of fluid flow down of the third or upper frac plug 100C permits the pumping of fluid down the wellbore 1 to create a pressure increase above the frac plug 100C. Fluid can continue to be pumped down the wellbore 1 until the pressure is adequate to hydraulically fracture the formation 5 though the perforations 10C in the
casing 6. Thus, the formation 5 may be hydraulically fractured without the need to pump a plug, such as a ball or dart, down the wellbore to be seated to create a seal or inhibit fluid flow, which potentially reduces the time required to fracture each zone. Further, thevalve 200 of the frac plug 100C does permit the fluid to flow down through the frac plug 100C so that the formation 5 at second zone may be fractured through perforations 10B in thecasing 6 due to the placement of the second frac plug 100B. Likewise, the placement of the first frac plug 10A permits the fracturing of the formation 5 via the perforations 10A. As discussed herein, thevalves 200 in each of the frac plugs 100A, 100B, and 100C permits the flow of fluid upwards through the frac plugs 100A, 100B, and 100C. Thus, production of fluids from zones beneath each of the frac plugs 100A, 100B, and 100C may flow up the wellbore 1. The frac plug of the present disclosure may also be used to re-fracture a location that has been previously hydraulically fractured, if necessary. - The
frac plug 100 having a 200, 300, or 400 of the present disclosure provides a solid state device that may permit the fracturing of a wellbore formation 5 without the need to drop a plug, such as a ball, down the wellbore or actuate a valve. Thevalve frac plug 100 having a 200, 300, or 400 of the present disclosure permits the production of fluids while positioned within the wellbore. Further, the pressure of a zone below avalve frac plug 100 having the 200, 300, or 400 of the present disclosure will not build up as the pressure will be release due to the upward flow of fluid through thevalve frac plug 100. The number, location, and configuration of the frac plugs 100A, 100B, and 100C ofFIG. 6 is for illustrative purposes only and may be varied as would be appreciated by one of ordinary skill in the art having the benefit of this disclosure. For example, assingle frac plug 100 may be positioned below a zone to be fractured or any number of frac plugs 100 may be positioned along a wellbore 1. The horizontal wellbore 1 ofFIG. 6 is shown for illustrative purposes only as thefrac plug 100 of the present disclosure may be used in vertical, horizontal, and/or deviated wellbores as would be appreciated by one of ordinary skill in the art having the benefit of this disclosure. -
FIG. 7 shows one embodiment of amethod 500 of the present disclosure. Step 510 of themethod 500 comprises providing a body having an internal flow path that may be positioned within a wellbore. Themethod 500 includes providing a sealing element on an exterior portion of the body wherein the sealing element creates a seal within the wellbore atstep 520. Atstep 530, themethod 500 comprises providing a valve in communication with the internal flow path of the body, the valve inhibiting fluid to flow in a second direction through the valve with respect to fluid flow in a first direction through the valve. As discussed herein, the valve may be integral to the body or may be comprised of an insert that is positioned into a portion of the body. Themethod 500 optionally includesstep 540 of providing a central flow path through the valve that is in communication with the internal flow path of the body and step 550 of providing a plurality of projections along the central flow path.Option step 560 provide a plurality of secondary flow paths in communication with the central flow path, wherein fluid flowing in the first direction flows along the central flow path and the projections divert fluid flowing in the second direction through the secondary flow paths. - Although this disclosure has been described in terms of certain preferred embodiments, other embodiments that are apparent to those of ordinary skill in the art, including embodiments that do not provide all of the features and advantages set forth herein, are also within the scope of this disclosure. Accordingly, the scope of the present disclosure is defined only by reference to the appended claims and equivalents thereof.
