FACULTY LETTERS

YU-SHU WU - COMPUTER MODELING GROUP (CMG) CHAIR

In this past year, I have

been back to my normal

work at Mines teaching

and doing research after

a year-long sabbatical

leave of the 2014-2015

academic year. I would

like to mention that the

one-year sabbatical leave

was very precious and

beneficial to me. It was

during the one-year leave

that I finally found time to

complete and publish my

Dr. Yu-Shu Wu fFilrusitd bFlooowk in(“PMoruoltuipshaansde Fractured Reservoirs,” http://store.elsevier.com/Multiphase- Fluid-Flow-in-Porous-and-Fractured-Reser voirs/YuShu-Wu/ isbn-9780128038482/) in 2015. More importantly, I had the opportunity to meet and spend time with many former students, old friends, and former colleagues as well as several new friends, while working at two universities: China University of Petroleum (CUP) at Qingdao and King Abdullah University of Science and Technology (KAUST) of Saudi Arabia, as well as at Saudi Aramco Petroleum Company in Dhahran, Saudi Arabia. This one-year experience provided me a unique opportunity and helped me in many ways updating my knowledge in reservoir flow and simulation, simulator development, and better understanding global petroleum industry issues facing our industry around the world. As a result, I feel more confident and very positive for the future of our industry, especially during the current down time.

I would also gladly to report to you that in the past year, our research at the Energy Modeling Group (EMG) has continually made significant progress in developing and enhancing geomechanics coupled flow simulation theory and technology for modeling conventional and unconventional reservoirs as well as CO 2 sequestration. Our modeling approach for coupling thermal-hydrologic-mechanic- chemical (THMC) processes in reservoirs is leading the field of reservoir simulation in incorporating geomechanics in reservoir flow and simulation. We are investigating how to simulate fracturing and its propagating processes during high-pressure injection in reservoirs. In particular, earlier this year we completed a four-year project (funded by US DOE) for investigating a new cryogenic fracturing technology, i.e., using liquid nitrogen to frack rocks in laboratory. This is to explore a different, alternative waterless hydraulic fracturing technology with potential to overcome the drawbacks with the current water-based-fluid hydraulic fracturing practice. In addition, EMG is working hard to improve our own hydraulic fracturing simulator (FracCSM) for multistage fracturing along horizontal wells with consideration of stress shadow effect.

The high lights of the past year include the SPE Distinguished Member Award I received at in the 2015 SPE ATCE and attending the 2016 conference of Foundation CMG in Vienna in June.
