Diverse experience in petroleum engineering technology and strong background in reservoir and production engineering principles, working on conventional and unconventional reservoirs, onshore and offshore, US and international.

Petroleum Engineering:

-  Oil and gas asset evaluation, petroleum economics, decline curves, rate transient analysis (RTA)

-   Acquisitions and divestitures (A&D), field development plans (FDP), reservoir management and reserves

-  Reservoir simulation, uncertainty analysis, material balance, welltest analysis (PTA), EOR and IOR

-  Frac design and analysis in vertical and horizontal wells

-  Integrated production modeling for field optimization (IPM), nodal analysis.

 

Unconventional Resources:

-  Wolfberry (Wolfcamp and Spraberry oil shale) in Permian Midland Basin

-  Wolfbone (Wolfcamp and Bone Spring oil shale) in Permian Delaware Basin

-  Fayetteville gas shale in Arkoma Basin, Austin chalk in South TX

-  Tight-gas sands at Paradox Basin and Green River Basin in the Rockies

-  Haynesville shale in LA, Niobrara in DJ Basin, Mid-Continent Mississippi Lime.  

 

Conventional Fields:

-  Offshore continental shelf and deepwater fields across GOM

-  Offshore deepwater Brazil, Trinidad and West Africa

-  Onshore Louisiana, Alaska North Slope.

 

Petroleum Software:

-  ARIES or PHDWin for decline curves and petroleum economics. Topaze or IHS Harmony for rate transient analysis

-  Eclipse, tNavigator, Imex or GEM for reservoir simulation. Saphir or PanSystem for welltest analysis

-  MEPO or CMOST for assisted history matching & comprehensive uncertainty analysis using experimental design.

-  IPM-GAP for integrated field production modelling. MBal for material balance, Prosper for nodal analysis

-  Field and well data gathering from IHS, Wood Mackenzie, internal Oracle or other SQL databases

-  Spotfire for multivariate data analysis. Crystal Ball for risk analysis.

 

Project Management:
