A novel hydraulic fracturing gel realization for unconventional reservoirs

Abstract

Abstract Coal bed methane reservoirs possess low to ultra-low permeability. In order to improve the production from CBM wells, stimulation techniques were deployed. Background This article reviews the most cost-effective, time-saving, and eco-friendly fracturing fluid which is a mix of water, guar gum, and sodium acetate. This article also provides a detailed study of hydraulic fracturing in unconventional reservoirs. Results Unlike using diesel, biodiesel we have prepared a cost-effective frac-fluid which is not having any smoke point which depicts it as eco-friendly fluid. In this method there is no requirement of anti-settling agents, suspending agents, emulsifiers. Gel breakers are more efficient to break the linear gel. Conclusion The breakers inorganic compound ammonium persulfate and hemicellulose liquid. A reaction takes place on linear gel as it breaks slowly at down hole static temperature at 50 °C and 65 °C. So, experimental studies also prove this method is applicable for unconventional reservoir operations.
