Nov. 1993-Oct. 1995 Staff Geophysicist: Canadian Foothills,Frontiers & International

• Maracaibo Basin, Venezuela: Evaluated basin hydrocarbon habitat, utilizing all geological reports and three existing seismic data sets ( 4000km). Completed preliminary interpretation (3000 km) and recommendation from both paper sections and Landmark system on the La Ceiba and Catatumbo Exploration Bid Blocks.
• Alberta Foothills: Recommended successful land sale strategies, prepared and shot a 'sparce' 3-D, firmed up prospects, recommended locations, designed and shot two offset VSP's and recommended a successful deviation. Recommended horizontal re-entries and new locations over the Coleman pool, utilizing Landmark "grid-balancing" to character tie varied, non-intersecting, foothills data sets.
• North West Territories: Assembled a digital culture, well, map and in-house seismic data base, initiated an integrated basin/economic study, and recommended a specific course of action.
• West Newfoundland: Completed processing Q.C. and interpretation of the on-shore and off-shore data, recommended an onshore location in this new transpressional/transtensional basin.
• Jeanne d'Arc Basin: Completed development economics/sale evaluation of three pools.
• SE British Columbia Foothills: Full cycle exploration over an inner foothill 'tough-terrain/surface carbonate' prospect crossing the continental divide.
• NE British Columbia Foothills: Evaluated outer foothills (Nikanassin) lands, inner foothills Debolt prospects, and Sukunka Triassic potential on lands recommending five locations.

Nov. 1988-Nov. 1993 Exploration Coordinator: Foothills, Frontier, Deep Devonian and Geophysical Supervisor: Domestic Exploration

• Planned business strategy, tactics and budgeting, evaluated activity and drilling locations. Coordinated and technically consulted on all Canadian Exploration geophysical work.
• Plains: Completed many long-term and short-term 2-D and 3-D interpretation projects, both as a "team member" and on a "as needed" basis. Play types were Cretaceous clastic fluvial channels, Triassic clastic pinch-outs and tidal channels, Permian clastic erosional outliers and facies changes, Mississippian carbonate subcrops and fault closures, many Devonian carbonate banks, platform edges and pinnacle reefs, and basal clastic fault closures. Work varied from regional studies to pool developments, over the the entire Western Canadian Sedimentary Basin.
