PROFESSIONAL EXPERIENCE

PETRO TECHNICAL SERVICES/ SCHLUMBERGER, HOUSTON, TX 2011 – 2014

Sr. Staff Geophysicist,

Worked closely with R&D testing latest technologies on time data processing and depth imaging.

• Performed extensive testing to evaluate new algorithms from developers to ensure functionality was meeting customer expectations before releasing to production.

• Identified opportunities for improvement and proposed modifications/improvements for adaptation that resulted in higher effectiveness for later versions.

• Wrote best practices and lesson learned while mentoring others in implementing tactics into production.

• Documented testing plans and achieved results with supporting data examples which provided a resource library for future projects.

• Performed Finite Difference Modeling to simulate various scenarios utilizing synthetic data.

• Worked on simultaneous source acquisition separation techniques which significantly decreased turnaround time and cost, putting company far ahead from competitors in acquisition and processing segments.

• Performed Surface Wave Inversion and Modeling to solve near subsurface issues.

• Tested 4D repeatability on coil geometry acquisition to validate the effectiveness of such new acquisition technique versus the fourth dimension (time).

• Evaluated benefits of variable depth streamer geometry (ObliQ) Shooting in broadening the acquired seismic data band.

• Utilized DISCover Broadband Deep Interpolated Streamer Coverage as another band broadening technique.

• Contributed to IsoMetrix Marine Seismic Technology’s validation.

• Processed wave glider acquired data.

• Mentored employees in Deterministic Water De-multiple (DWD)

• Performed pre-stack regularization techniques such as Compact Fourier Interpolation (COMFI) and Matching Pursuit Fourier Interpolation (MPFI)

WESTERNGECO/ SCHLUMBERGER, HOUSTON, TX 2007 – 2010

Project Leader, Joined multi-client team taking the responsibility for subsalt imaging of several big surveys in South Texas and deep water Gulf of Mexico.

• Pre migration data conditioning

• Building and editing vertical & tilted transverse isotropy velocity models (VTI & TTI)

• CIP tomography.

• Applying steering filters to localized anisotropic tomography using well data to steer the updates along seismic horizons.

• Well ties

• Residual move out QC (RMO QC)

• Pre stack depth migration

WESTERNGECO/ SCHLUMBERGER, HOUSTON, TX 2004 – 2007

Sr. Processing Geophysicist, joined WesternGeco working on third party projects

• Processed 3D Marine and deep water Gulf of Mexico and also ocean bottom cable (OBC) in Gulf of Mexico.

• Processed 3D data from Gulf of Mexico Coast Transition zone.

ADDITIONAL EXPERIENCE

CGG, CAIRO, EGYPT

Sr. Processing Geophysicist, land and Marine 2D data project leader

• Contributed in processing 3D land and marine as well.

• Came up with 2 new techniques for pre stack mute picking (manual and automatic)

CGG, MASSY, FRANCE

Sr. Processing Geophysicist,

• Processed 2D marine data.

• Proposed and applied improvements to some QC tools.

CGG, MUSCAT, OMAN

Processing Geophysicist, Processed 2D land data.

• Developed two new innovative ideas, received awards from PDO and CGG. One of the ideas had significant impact on PDO’s database, and the other on CGG noise attenuation manual method, which was replaced eventually by the new semi-automatic technique.

HALLIBURTON GEOPHYSICAL/ WESTERN GEOPHYSICAL, CAIRO, EGYPT

Processing Geophysicist,

• Processed 2D land and marine seismic data from Egypt and Middle East.

• Processed first OBC survey in Egypt summing geophone and hydrophone data (PZ summation) with great results led to the project’s success.

EDUCATION
