Sr. Structural / Operations / Development / Exploration Geologist (Contactor through Professional Geological Services) Remapped West, North Field (over 200 wells and specifically the Platform 15 Area) targeting the structure of multiple stacked, clastic reservoirs using Stratworks, Seisworks and Z Map+ and G&G Integration of 3D Seismic, Wireline, Core, LWD, Mudlogging, Production / Drilling History, Geo-Seismic and Bio-Stratigraphic Data to identify new Exploration and Production prospects. Conducted Private Study in 2002-2004 of the Los Bajos-Soldado Transform Zone in West Trinidad and the Gulf to Paria (GOP) to better explain sustainability in certain West Block wells and remapped the S.E. Caribbean Plate Boundary which identified the Trinidad Microplate.

Sr. Studies Geologist – Regional Tectonic Study

Wellsite Formation Evaluation Services, Limited

Sept 2001 – Dec 2004, Trinidad, West Indies

S.E. Caribbean Plate Boundary and Subduction Mapping - West Gondwana

Integration of at least 50 Regional Tectonic Studies by renowned NeoTectonic Workers with Local Outcrop and Fault Studies with prototype MIRRAH RF Magneto-Telluric equipment (Developed in Trinidad W.I by Wellsite Formation Evaluation Services). Study indicates that a major portion of the island of Trinidad (East of the Los Bajos Fault) is potentially a microplate (Trinidad Microplate) within the wide zone of deformation between the Caribbean Plate and South American Plate. The Los Bajos being identified as a Micro-Transform and the portion of Trinidad south of this boundary being part of the South American Plate at this complex, West Gondwana Transform Boundary. The Study identified multiple new prospects and at least one new Subduction Zone Play. Identified in 2004, six of the land prospects have now been proven. At least another six prospects including what appears to be the eastern extension of the El Furrial Supergiant Trend in Eastern Venezuela, are still undrilled. The quest to fully understand the Gondwana-Laurasia Imbricate Transform Zone (GLITZ) continued in the Middle East in 2005 where an important (possibly sustainable) fluvio-glacial, Cambro-Ordovician Deep Gas / Condensate / Sweet Oil play called Furat (Arabic for Euphrates) has been identified in East Gondwana.
