Major Projects

Flagg’s prospective resources evaluation experience is focused on potential reservoir performance and development concept planning. Using D&M’s proprietary, simulation-based software, Flagg has simulated potential reservoir performance and generated potential production profiles and recovery factor ranges predicted on actual rock and fluid physics.

His capabilities also extend to the creation of individualized development concepts, based on client and geographic needs, to ensure a consistent platform for concept screening, optimization, and cost control. Subsequent cost estimations and monthly cash flows produced for these development concepts support feasibility studies and final concept selection for new oil and gas field development.

Some of his most recent projects involved leveraging his chemistry background to assist clients in Australia, Europe, and North America in creating internal GHG guidelines and requirements in accordance with applicable regulatory environments and in estimating direct and indirect emissions based on the United Nations Intergovernmental Panel on Climate Change (IPCC) or ISO 14064 standards. Flagg has further assisted clients within the United States with maximizing their 45Q tax credits due to enhanced oil recovery operations or permanent storage.
