Advanced Well Stimulationand Field Problems

Dr. Hisham A. Nasr-El-Din is a professor and holder of John Edgar Holt Endowed Chair at Texas A&M University

in petroleum engineering. Previously, he worked for 15 years as Principal Professional and Team Leader of the

Stimulation Research and Technology Team, Saudi Aramco. Before joining Saudi Aramco, he worked for four

years as a staff research engineer with the Petroleum Recovery Inst. in Calgary. He also worked as a research

associate with the U. of Saskatchewan, the U. of Ottawa, and the U. of Alberta, all in Canada. His research

interests include well stimulation, formation damage, cementing, drilling fluids, two-phase flow, enhanced

oil recovery, rheology, conformance control, interfacial properties, adsorption, and non-damaging fluid tech-

nologies. Nasr-El-Din has several patents and has published more than 440 technical papers. He is an adjunct

professor with the U. of Alberta and has supervised several MSc and PhD students. He has received numerous

awards within Saudi Aramco for significant contributions in stimulation and treatment-fluid technologies and

stimulation design, and for his work in training and mentoring. Nasr-El-Din holds BS and MS degrees from Cairo

U. and a PhD degree from the U. of Saskatchewan, Canada, all in chemical engineering. He serves on the SPE

steering committees on corrosion and oilfield chemistry, is a review chairperson for SPEJ and is a technical edi-

tor for SPEPO, and SPEDC. He was invited to give keynote presentations in various SPE and NACE conferences.

He received the SPE Regional Technical Discipline Award for Production and Operations in 2006, was named a

Distinguished SPE Member in 2007, and received SPE awards for Outstanding Associate Editor (SPEJ) and Out-

standing Technical Editor (SPEPO) in 2008. In addition, he received SPE Production and Operations Award and

Outstanding Associate Editor Award (SPEJ) in 2009.

Course Descriptionhe course is designed for engineers who deal with well performance enhancement. The course will go through various techniques that can be used

to enhance productivity of oil and gas wells. This is fol-lowed by overview of acid and hydraulic fracturing, ma-trix treatments for carbonate and sandstone formations. Issues related to candidate selection, treatment design, selection of acid additives, lab testing, acid placement, QA/QC, job execution, and treatment evaluation will be discussed in detail. The course will end with introducing new technologies for carbonate and sandstone acidizing. Field cases will be given to highlight problems and how lab testing was used to find cost effective solutions to these problems.
