Research & Scholarship

Current Research and Scholarly Interests

I was born in Pakistan and came to the U.S. in 1952 to study engineering. Since then I have spent most of my life in Canada and the U.S.A. working both in academia and industry. I have also worked in Pakistan for the Karachi Gas Company. I have also founded the Computer Modelling Group (CMG) and co-founded Neotechnology Consultants. While I am no longer formally associated with these companies, they have been highly successful in their respective fields.

Research
The overall goal of my research is the development of robust and reliable models for predicting performance of hydrocarbon reservoirs (including shale oil and gas) and CO2 sequestration operations. Over the years I have been involved with the development of four different industrial consortia dealing with different aspects of this problem. The first was on reservoir simulation (SUPRI-B), the second on data integration (SCRF), the third on advanced wells (SUPRI-HW), and the most recent one on Smart Fields (SFC). Underlying my research is the desire to understand mechanisms involved during the flow of complex mixtures in porous rocks and in pipes, and efficient modeling of these processes on computers. While I am no longer directly involved with SCRF and we have merged SUPRI-HW with other programs, I co-direct the other two consortia. All are highly successful and have led to a number of developments and innovations that have found important applications in industry.

Teaching
While I have been extensively involved in teaching in the past, I am slowly winding down my activities in this area. I still give lectures in some courses but I do not teach any full courses. I do participate in a summer short course on reservoir simulation that we offer each year for industry people. My main current activity at Stanford is research.

Professional Activities
In 2008 I was awarded the degree of Doctor of Laws (Honoris Causa) from the University of Calgary for my contribution to that university before moving to Stanford. In 2006 I received the Lifetime Achievement Award of the Petroleum Society of Canada and in 2005 I received the Blaise Pascal Medal in Earth Sciences of the European Academy of Sciences. In previous years I have received numerous national and international awards. I serve on the Advisory Board of several universities in Pakistan and have been particularly active in developing a new School of Science and Engineering at LUMS in Lahore. This school admitted its first undergraduate class of about 160 outstanding freshmen in 2008. I am a member of the national Academy of Engineering.
