3. Work Experiences
NOVEMBER 2010 – PRESENT, SENIOR GEOSCIENTIST, GDF SUEZ GROUP, EGYPT
• Responsible for prospect generation and maturation in West El-Burullus
Concession, Western Nile Delta, Egypt. We created many leads and prospects
within the Pliocene and Miocene sequences that ranged from deltaic to
deepwaterreservoirsutilizing the seismic direct hydrocarbon indicators (DHIs)
interpretation, seismic sequence stratigraphy and reservoir geophysics
concepts. We made risk assessment Basedonthese analyses; several high grad
drillable prospects have been generated and maturated for drilling. This work
startedfrom3D seismicinterpretation,mapping,time todepthconversion,rock
physics analysis, in-house seismic inversion and well planning.
• Interpreted and analyze multi-azimuth 3D seismic data sets to delineate the
subtle stratigraphicfeatures/elementsespeciallybelow the Messinainanhydrite
and to generate regional maps of the interested events/horizons.
• Responsible for development of two Pliocene gas discoveries in the West El-
Burullus Concession, Western Nile Delta, Egypt. We created pre-stack
simultaneouselasticinversionmodels to generate elastic properties that could
helptodelineate the changesinthe faciesandpetrophysical properties. Alsowe
used the seismic sequence stratigraphy and the seismic geomorphology
concepts to delineate the depositional architectural elements of these two
reservoirs and integrate the results with the seismic inversion products. We
achieved these goals that helped to optimize the locations of the upcoming
development wells.
• Createdcomprehensiverockphysicsmodelsfordifferent stratigraphic levels to
understand the possible characteristics of the gas-bearing reservoirs within
these sequences and to investigate the effect of pore fluid type/saturation,
porosities, clay content and pressure on the seismic acoustic and elastic
prosperities.
• Built AVO synthetic models to link the changes in the rock properties to the
changes in the pre- and post-stack seismic signatures as well as the AVO
attributes such as intercept, gradient and reflectivity.
• Key member of the Nile Delta new opportunities team which responsible for
evaluationof the bidround and farm-in blocks in the western and eastern Nile
Delta in both onshore and offshore portions.

4. • A keymemberof the new venture teamwhichresponsible toevaluate/rank the
onshore opportunitiesinthe WesternDesert and Gulf of Suez for conventional
and un-conventionalplays. Thisworkincludes3D and 2D seismic interpretation
to generate regional andsemi-regional mapsandconvertthose mapsintodepth
domains.
• Basinanalysisstudiesforseveralbasinsin the Western Desert including source
rock evaluation, hydrocarbon migration modeling and structure restoration
studies.
• Representative of the GDF SUEZ Group in many scientific seminars around the
world (Norway, France and the Netherlands) to show several case studies and
the lesson learned from them.
DECEMBER 2009 – NOVEMBER 2010, GEOPHYSICIST, PGNIG GROUP, EGYPT
• Key member of the work team who responsible for prospect generation in
BahariyaConcession,Western Desert, Egypt. Many leads have been generated
within several sequences utilizing the interpretation of 2D seismic data sets.
• Integrated the geophysical potential fields (gravity and magnetic) with the
available 2D seismic data sets to delineate the basement-related faults and to
estimate the depth to basement.
DECEMBER 2006 – NOVEMBER 2009, DEVELOPMENT GEOPHYSICIST, BG/RASHPETCO J.V., EGYPT
• Responsible fordevelopmentof the Pliocene Sequoiagasfieldin the WestDelta
Deep Marine (WDDM) area, Western Nile Delta, Egypt. We applied the
complete workflowtothisfieldstartingfrom3D seismic interpretation through
seismicspectral decomposition and geomorphology. We carried out different
kindof seismic(post- andpre-stack) inversionmodels to delineate the changes
inthe faciesandrock parameterswithinthisverycomplicated field to optimize
the developmentwell locations to drill the good quality thick gas-bearing sand
and to avoidthe penetrationof the perchedwaterleg(s). We obviously succeed
to develop the whole field with the lowest number of wells (only six) and
produce the most gas volume from it.
• Createdcomprehensiveseismicgeomorphologicstudiesof manyof gas fields in
the WDDM area, Western Nile Delta, Egypt to delineate the depositional
architectural elementsof these reservoirsto understand the static connectivity
of their parties which affect the development plans and number of
development wells.

5. • Generatednewprospects withinthe UpperMiocene sectionbelow the Sapphire
gas field, andwithinthe EarlyPliocene sectionbelow the Simian gas field in the
WDDM area, western Nile Delta, Egypt. We created these prospects by the
integration between the seismic DHI interpretation, spectral analysis and
seismic stratigraphy concepts.
• QC representative geophysicistassistinginall internal/externalseismicinversion
projects since 2008 till the November 2009.
• Representative Rashpetco in many technical meetings with the partners and
contractors.
