The slips may include buttons, which are used to anchor the frac plug in the casing. To ensure sealing and sufficient anchoring with the casing, the frac plug tends to be formed with relatively precise and expensive components. In addition to the expense, the construction of such a frac plug also can lead to difficulties associated with milling out the frac plug after completion of the fracturing operation.

- The present disclosure generally relates to an apparatus and method for facilitating a fracturing operation. Specifically, one or more embodiments of the present disclosure are directed to voided buttons made out of a moldable material, such as a powder metal material or a ceramic material, for use in a downhole tool during a fracturing operation. Because the voided button is made out of a moldable material, no machining of the button is required, which provides a significant cost savings. Moreover, the voided button exhibits improved performance during drill out.
- Referring generally to
FIG. 1 , an embodiment of adownhole tool 20 is illustrated deployed in awell 21. According to one or more embodiments of the present disclosure, thedownhole tool 20 is a frac plug. For example, thefrac plug 20 may be deployed in awellbore 22 to facilitate a fracturing operation. In the example illustrated, thefrac plug 20 is deployed in thewellbore 22 so as to isolate a zone of thewellbore 22 so thatfracturing fluid 24 may be directed throughperforations 26 and into a surroundingformation 28 uphole of thefrac plug 20 for fracturing of the surroundingformation 28. It should be noted that thefrac plug 20 according to one or more embodiments of the present disclosure may be used in many types of wellbores, such as deviated, e.g., horizontal, wellbores to facilitate fracturing of desired well zones along the horizontal or otherwise deviated wellbore. - Still referring to
FIG. 1 , thewellbore 22 may be lined with acasing 30, and eachfrac plug 20 may be actuated to grip into and seal against thecasing 30, thereby sealing or substantially restricting flow of thefracturing fluid 24 downhole of thefrac plug 20 in thewellbore 22. As a result, during a fracturing operation, thefracturing fluid 24 is directed through theperforations 26 into the surroundingformation 28 while thefrac plug 20 remains anchored to thecasing 30. Once the fracturing operation is completed and a givenfrac plug 20 is no longer of use, the frac plug may be milled and removed from thewellbore 22. - Referring now to
FIG. 2 , a perspective view of a frac plug having voided moldable buttons according to one or more embodiments of the present disclosure is shown. Specifically,FIG. 2 shows thefrac plug 200 in an unset position. Referring also toFIG. 3 , thefrac plug 200 ofFIG. 2 is shown set in thecasing 30. According to one or more embodiments, thefrac plug 200 may include a mandrel (not shown) and at least upper andlower slip assemblies lower cones sealing element 206, and at least onebarrier ring 208 disposed around the mandrel. In one or more embodiments, the at least onebarrier ring 208 is disposed adjacent thesealing element 206, and the at least onebarrier ring 208 may include a plurality offlanges 210, which may radially expand against an inner wall of thecasing 30 and create a circumferential barrier to keep the sealingelement 206 from extruding. Thefrac plug 200 may also include abottom sub 212 having achamfered end 214 according to one or more embodiments. - Still referring to
FIGS. 2-3 , the upper andlower slip assemblies frac plug 200 may include a plurality ofslips 216. Further, eachslip 216 may include aslip body 218 and at least one voidedbutton 220 disposed in theslip body 218. The voidedbutton 220 is further described below with reference toFIGS. 4a and 4 b. - When the frac plug 200 transitions from the run-in-hole unset position of
FIG. 2 to the set position ofFIG. 3 , theupper slip assembly 202 a ramps down theupper cone 204 a, and thelower slip assembly 202 b ramps up thelower cone 204 b, causing the upper andlower slip assemblies button 220 disposed in theslip body 218 of a givenslip 216 to grip and bite into the inner diameter of thecasing 30. Further, when thefrac plug 200 is in the set position, thesealing element 206 is deformed into sealing engagement with the surroundingcasing 30. According to one or more embodiments of the present disclosure, the sealingelement 206 may be formed of an elastomeric material or metal material, which is deformed in a radially outward direction until forming a permanent seal with the inside surface of thecasing 30. Due to the gripping and biting of the at least onevoided button 220 and the sealing of the sealingelement 206, thefrac plug 200 is able to be effectively anchored to the inside surface of thecasing 30 when thefrac plug 200 is in the set position. Thefrac plug 200 may remain anchored to the inside surface of thecasing 30 during a fracturing operation, and after the fracturing operation, thefrac plug 200 may be drilled out, as previously described. - Referring now to
FIGS. 4(a) and 4(b) , perspective and top views of a voidedbutton 220 according to one or more embodiments of the present disclosure are shown, respectively. As shown, the voidedbutton 220 includes abody 222, which may be cylindrical, for example, and avoid 224 that pierces thebody 222 completely therethrough. Although thebody 222 is shown as being cylindrical inFIG. 4(a) , other shapes and configurations of thebody 222 are feasible and are within the scope of the present disclosure. As also shown inFIG. 4(b) , the void 224 pierces thebody 222 through a flat surface of thebody 222, according to one or more embodiments of the present disclosure. - Still referring to
FIGS. 4(a) and 4(b) , thebody 222 of the voidedbutton 220 is made out of a moldable material according to one or more embodiments of the present disclosure. In one or more embodiments, the moldable material may be a powder metal material or a ceramic material, for example. That is, according to one or more embodiments of the present disclosure, thevoid 224 is not machined into thebody 222 to create the voidedbutton 220. Instead, the voidedbutton 220 is manufactured using powder metal or ceramic during a molding process with the void 220 already present in the mold. Stated another way, powder metal (or ceramic) molding can produce the button in its current form, including voids, without the need for machining. Further, powder metal and ceramic materials have a requisite hardness such that the resulting voidedbutton 220 is sufficiently hard enough to grip and bite the inside surface of thecasing 30 when thefrac plug 200 is in the set position. - Due to the affordability of powder metal and the potential to eliminate machine work, the powder metal molding process as previously described may reduce the cost of the voided
button 220 by up to 90%. There are commercially available powdered metals, which have low elongation, but comparable tensile strength to 8620 steel. As appreciated by those having ordinary skill in the art, low elongation generally indicates that a material will fracture and mill more easily. - In other embodiments, 3D printing or additive manufacturing are other manufacturing methods that could be used to manufacture the voided
button 220. - Still referring to
FIGS. 4(a) and 4(b) , thevoid 224 facilitates drill out of the voidedbutton 220 and thefrac plug 200 after a fracturing operation, for example. That is, the voidedbuttons 220 according to one or more embodiments of the present disclosure exhibit significantly improved performance during drill out over the solid and un-voidedprior art button 500 shown inFIGS. 5(a) and 5(b) , for example. In particular, thevoid 224 allows the voidedbutton 220 to drill out faster and into smaller pieces than the solid and un-voidedprior art button 500. As appreciated by those having ordinary skill in the art, the ability to drill out a frac plug quickly is an extremely critical aspect of frac plug performance. The addition ofvoids 224 to thebuttons 220, according to one or more embodiments of the present disclosure, make the voidedbuttons 220 easier to chip away at while still anchoring thefrac plug 200 in place during the fracturing operation. - Moreover, the synergy of combining a button molded out of powdered metal (or ceramic) with a void completely piercing the body of the button therethrough, according to one or more embodiments of the present disclosure, achieves superior results and exhibits an unmistakable improvement in average fracture size during impact testing over the solid and un-voided prior art button of
FIGS. 5(a) and 5(b) , for example. - Although a few embodiments of the disclosure have been described in detail above, those of ordinary skill in the art will readily appreciate that many modifications are possible without materially departing from the teachings of this disclosure.
