Ultra-Fine Particles (UFP) to Enhance Microfracture Permeability

Unconventional reservoirs are characterized by low permeabilities and are generally anisotropic, highly laminated and contains varying levels of natural fracturing. In order to unlock these reservoirs, horizontal drilling and hydraulic fracturing with slickwater has been used amongst other technologies to assess and tap these resources. During the fracturing process a fracture network is typically formed that connects the reservoir back to the wellbore by exploiting the natural fracture system in the rock or by inducing microfractures during the process. This fracture network could be as simple as a planar fracture to more complex dendritic network throughout the stimulated reservoir volume of ultra-low perm reservoirs. To maximize recovery, it is not enough to simply create these complex networks but also consider enhancing and sustaining the complex networks long enough to contribute to production. One way of sustaining these networks is by placing a propping agent into these microfractures. However, the microfracture and natural fracture have been shown to have apertures less than 100 microns which is much smaller than 100 mesh proppant and also most commonly used proppant today tend to settle quickly in low viscosity fluids. To gain access to the microfractures, fine particulates much smaller than nominal 100 mesh is needed.

This presentation talks about the application of ultrafine particulates in hydraulic fracturing of unconventional reservoirs as a stimulation additive. We consider its ability to suspend in a carrier fluid, access microfractures and improve permeabilities of the microfractures. We also take a look at some case studies of filed applications with good success from stimulation and production standpoint.

Janette Cortez-Montalvo has been with the company for 6 years and her technical focus areas have included: micro-fracture stimulation additives, diverters, fluid formulations, fluid rheology, Design of Experiments and leading projects from concept to commercialization.  Janette graduated from Texas Tech University in 2007 with a BS in Chemistry and a Master’s of Science Interdisciplinary Studies (specialized in Forensic Science) in 2010.   

Ubong Inyang is a graduate of the University of Uyo, Nigeria with a bachelor’s in Petroleum Engineering. After college he began employment with Halliburton in August 2008 in Williston, North Dakota. He spent four years designing and pumping stimulation treatment in the Bakken and Three Forks formation. He then transferred to the Houston Technology Center in 2012 to work as a principal technical professional in the applied sciences group. He works on various research projects like fracturing fluids, diverters, stimulation methods and also assists in deploying new products to the field.
