For taking my passion to a higher level, I decided to continue my studies at the Ph.D. level at the University of British Columbia. I was lucky enough to get a research offer in the subject of Rock Engineering/Hydraulic Fracturing. The main focus of my studies is on numerical modeling of hydraulic fracturing in weak discontinuous rock mass. In the last two years, I worked on two different aspects of improving hydraulic fracturing design to increase the economic production of natural gas following reservoir stimulation. The results show great potential in providing a deeper understanding of the influence of pre-existing fractures as well as stress shadow effects on the propagation of hydraulically induced fractures.
