Objects and tools for use in hydraulic fracturing and methods of manufacturing same
Embodiments disclosed herein include dissolvable and intentionally degradable objects that are useful for hydraulic fracking operations. Such objects are at least in part manufactured using materials that are soluble in certain fluids including water. The dissolvable and intentionally degradable fracking objects can be manufactured from one or more materials, including composite materials. In one embodiment, dissolvable fracking objects are manufactured from ceramic materials that are soluble in fluids such as water. Such dissolvable fracking objects include fracking balls and plugs. These fracking balls and plugs are arranged to seal a well for a predetermined period of time and dissolve over that predetermined period of time until the well is no longer sealed. In another embodiment, tools generally useful in fracking operations are manufactured to have desirable elastomeric properties. Such tools can be manufactured from a combination of materials that are soluble in fluids and generally dispersible in fluids.
1. A method of manufacturing a fluid soluble hydraulic fracking tool comprising the steps of:
dehydrating borates, wherein the dehydrated borates comprise 50% to 60% bounded water;
forming a mixture from the dehydrated borates and additives;
heating the mixture to a first temperature to form a molten mixture;
pouring the molten mixture into a mold;
cooling the molten mixture to a second temperature to form the fluid soluble hydraulic fracking tool; and
removing the fluid soluble hydraulic fracking tool from the mold.
2. The method of claim 1 , wherein the mixture further includes nanotubes.
3. The method of claim 1 , wherein the first temperature is between approximately 1000° C. and approximately 1300° C.
