An independent assessment of exploration resources, whether in association with reserve evaluation work or as a stand alone project, is an important service we provide to our clients. A reliable risk and volumetric assessment of undiscovered, untested, or undeveloped hydrocarbons requires knowledge and understanding of basin-wide petroleum systems and the ability to assess and rank prevalent play types, prospective areas, and potential hydrocarbon volume distributions. Our exploration resource assessment team is comprised of geoscientists and reservoir engineers with extensive exploration experience who have applied this expertise for clients worldwide.

Our experts are proficient in the proper implementation of probabilistic resource estimation and conducting thorough prospect risk assessments. NSAI’s 45-year history of conducting field and reservoir evaluations provides a solid foundation for field development planning, forecasting product deliverability, and generating cash flow models of potential hydrocarbon discoveries. Our integrated geologic, engineering, and economic assessments provide a ranked and risked portfolio analysis that can help in making informed business decisions regarding exploratory expenditures, potential acquisitions, farm-outs/farm-ins, property trades, lease sales, or lease relinquishments.

Our scope of work may include:

• Review client data to identify potential hydrocarbon accumulations or conduct a review of the client’s prospect inventory
• Analyze the prospective basin based on experience supplemented with published literature
• Conduct probabilistic volumetric assessment of prospects and leads using pertinent well log, seismic, and analogous reservoir data
• Perform prospect risk analysis considering source rock volume, quality, type, and thermal maturity; migration pathways and timing; trapping mechanisms; seal capacity; and reservoir presence and quality
• Aggregate resources by play type and by block or region
• Prepare potential development plans and economic models
• Assemble a ranked portfolio of exploration opportunities
• Provide detailed reports with discussion, figures, text, and tables
