About the Event

Course Description

Brown fields requires certain skills to evaluate its potential and to economically decide its future. To properly evaluate the brown fields for both Clastics and Carbonate reservoirs, a combined proper understanding of the original reservoir status is crucial to fully predict the potential of the current field status. This course takes the students through these stages, define the field parameters in each stage, compare between the classical and the modern models of evaluation, reviews the initial and the current fluids saturation methods and analyses and use the statistical approach to properly define the current field status. The course contains multiple examples and interpretation methods using multiple fields’ examples and exercises.

Career Path

  • August 2017 – Currently, Professor at the American University in Cairo.
  • Jan. 2016 – July 2017, Professor at Future University.
  • Sep. 2012 – Dec. 2015, North Africa technology manager for Halliburton. Responsible for integrated project and unconventional reservoirs.
  • June 2008 – Sep. 2012, Double Responsibility: Middle East Regional Manager (petrophysics) and Global Development Team Manager for Sperry Drilling Services. The responsibility of this position is to manage and improve the position of Sperry in the region. Build a team of log analysts to improve the log quality and deliverables to customers. The region includes Egypt-Saudi Arabia-UAE-Oman-Kuwait-Qatar-Pakistan. The promotion of new technology is critical in this position. The team members are 11 petrophysicists.
  • June 2004 – 2008. Formation Evaluation Asset Team Manager Worked with Landmark asset teams to improve the integration of petrophysics in reservoir evaluation. Personally performed multiple field studies with the Landmark asset team: Umm Gudair uncertainty OOIP, Lower Minagish OOIP and Burgan Jurassic reservoirs and Dukhan Field
  • 2001- June 2004 Egypt Technology Manager with Halliburton. The responsibility of this job is to integrate the technology of all product lines involved in projects. Integrate the Logging and perforation and LWD for formation evaluation, integrate Baroid with the formation evaluation group to provide a problem free drilling and borehole stability, proper choice of bits from SDBS and proper choice of cement depending on formation and reservoir characteristics. Enhance the well deliverability by performing “well Stimulation Plan” for all Egypt reservoirs. This resulted in huge improvements in the deliverability of Upper Baharaia Laminated Shaly Sand reservoir by a factor of 7. The technology team members were 23 engineers
  • 1997-2001 Chief Petrophysicst for Halliburton Middle East (Wireline). Based in Dubai. In this capacity, I managed the log analyst team in general but I was personally leading the introduction and interpretation of the Magnetic Resonance Imaging Log combined with all other Logging and Perforating logs to provide the customers with formation evaluation solution.
  • 1996-1997 Interpretation and Development Group, then Group Leader based in Houston. In this capacity, I developed all the MRIL interpretation software that Halliburton used prior to merging with NUMAR. I was involved in solving many petrophysics problems in many countries all over the world; Argentina, Brazil, Venezuela (South America), Egypt, Kuwait, Qatar, India (Middle East)
  • 1995 – 1996 Senior Petrophysicist with Schlumberger. Based in Cairo, Egypt. In this capacity I was a member of the interpretation team of Schlumberger.
  • 1990-1996 Reservoir Team Member. Worked with ARCO Exploration and Production Technology AEPT, as an engineer. The experience is in North America; Prudhoe Bay, Kuparuk, Pt. McIntyre, Sunfish (North Slope), Long Beach, Bakersfield (California). Worked in asset groups in ARCO to evaluate the above mentioned reservoirs
