Primary project: Predictive fracture modeling and reservoir simulation of unconventional oil and gas reservoir well pads.This project required the development of a general purpose poroelastic pad-scale reservoir-coupled fracturing simulator that could be applied to various applications in the oil and gas industry.Key highlights:-> Developed a 3-D poroelastic pad-scale reservoir-coupled fracturing simulator to simulate competitive growth of multiple fractures in multiple wells. This simulator has been used and co-developed by various graduate students at UT for their research projects. -> Designed a graphical interface for the simulator (Multi-Frac suite - www.austingeotech.com) to allow users from the industry to take advantage of the advanced capabilities in their workflows.-> Provided consulting services to several companies using the developed models and applying workflows to their assets.Multiple collaborative sub-projects:1.

• Reduced millions of dollars in capital expenditure for operators by performing completions design optimization and developing reservoir fluid and stress management strategies in various US basins. • Reduced risk of parent well damage from child well frac hits in the Permian, STACK, Bakken and Eagle Ford by developing mitigation strategies such as refracturing, pre-loading, optimizing child well completions design and real-time workflows.• Combined geomechanics and reservoir simulation to improve IOR methods and strategies such as huff-n-puff.

Micro-mechanical modeling of the mechanical, failure and flow properties of unconsolidated sands using discrete element methods.Supervisors: Prof. Mukul M. Sharma & Dr. Jon E. Olson• Leading a project to simulate experiments conducted on unconsolidated sands using discrete element methods. These experiments include uniaxial, biaxial & triaxial tests performed at various confining pressures. • Challenges included modeling and visualizing the experimentally observed shear failure in the samples; and simulating the flow of fluid through the samples to observe the permeability change due to failure. • The simulation software used to replicate the mechanical behavior of the pack was Particle Flow Code 3D, developed by Itasca. Additional visualizations were accomplished using codes written in Matlab. Flow simulations were performed using a pore network modeling approach to simulate the flow through the granular packs and capture the effect of local deformation.
