Abstract: A method is described for stimulating a subterranean formation penetrated by a wellbore by injecting a pill through the wellbore at an injection pressure below hydraulic fracking pressure. This is accomplished by introduction of a first volume of non-aqueous liquid to the wellbore, followed by introduction of anhydrous liquid ammonia, and this followed by introduction of a second volume of a non-aqueous liquid into the subterranean formation, wherein the anhydrous liquid ammonia is sandwiched between the first volume of non-aqueous liquid and the second volume of non-aqueous liquid, thereby forming the pill. A volume of push-fluid is then introduced to the wellbore to push the pill into the formation and allow the anhydrous ammonia to react with water in the formation to increase the pressure and form microfractures. However, the pill is introduced into the subterranean formation at injection pressure, and substantially below the hydraulic fracking pressure of the formation.

Abstract: This disclosure provides drilling fluids and additives as well as fracturing fluids and additives that contain cellulose nanofibers and/or cellulose nanocrystals. In some embodiments, hydrophobic nanocellulose is provided which can be incorporated into oil-based fluids and additives. These water-based or oil-based fluids and additives may further include lignosulfonates and other biomass-derived components. Also, these water-based or oil-based fluids and additives may further include enzymes. The drilling and fracturing fluids and additives described herein may be produced using the AVAP® process technology to produce a nanocellulose precursor, followed by low-energy refining to produce nanocellulose for incorporation into a variety of drilling and fracturing fluids and additives.
