SUMMARY

Thirty-five years of experience in oil exploration, with majority of time spent in seismic interpretation. Areas mapped include Gulf of Mexico, North Sea, South America, northwest and West Africa. Discovery geophysicist on Yombo Field, offshore Congo, where geological and geophysical interpretations were successfully integrated. Mapped 3-D survey over El Furrial Field, Venezuela. Background also includes seismic acquisition/ processing, negotiations /management, and hydrocarbon systems analysis. Participated in regional studies of north Africa/Mediterranean and northeastern Mexico. Computer skills include Landmark’s OpenWorks/SeisWorks 2003.0, GeoQuest IESX 4.2.1, SMT, Petrosys, VelPro.

EXPERIENCE

VAALCO ENERGY – Houston, Texas August 2008-Current

Senior Geophysicist – Mutamba-Iroru (Onshore Gabon), Block 5 (Angola)

-Managed 2008 proprietary 3D acquisition in Angola Bock 5.

-Mapped onshore Gabon Mutamba Iroru (SMT) acreage and defined new prospects. Part of farm-in team that brought Total into acreage. Coordinated reprocessing of existing 2D as part of farm-in agreement with Total.

-Mapped offshore Angola Block 5 2008 3D (SMT) and integrated it with 1997 WesternGeco 3D speculative data. Defined new post-salt and pre-salt prospects and added value to those previously mapped in 1997 3D. Created velocity model (VelPro) used for depth conversion of pre-salt prospect.
