Prospective Resources Assessments

An independent assessment of prospective resources, whether in association with reserves evaluation work or as a stand-alone exploration 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 prospective resources assessment teams are comprised of geoscientists and reservoir engineers with extensive exploration experience who have applied this expertise for clients worldwide.

To talk to one of our Prospective Resources Assessment experts, call either Phil Hodgson in our Dallas office at 214-969-5401 or Ed Roy in our Houston office at 713-654-4950. We can also be contacted by email at for more information.

Our experts are proficient in the proper implementation of probabilistic resources estimation and prospect risk assessments. NSAI’s 60-plus year history of conducting field and reservoir evaluations provides a solid foundation for field development planning, forecasting product deliverability, and generation of 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 exploration expenditures, potential acquisitions, farm-outs/farm-ins, property trades, lease sales, or lease relinquishments.

Our scope of work may include:
  • Review of a client’s data to identify prospective hydrocarbon accumulations or conduct a data-based review of the client’s prospect inventory
  • Analyze the prospective basin based on worldwide experience supplemented with published literature
  • Conduct probabilistic volumetric assessments of prospects and leads using pertinent well log, seismic, and analogous reservoir data
  • Perform prospect risk assessment 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/or by block or region
  • Prepare scoping development plans and economic models
  • Assemble a ranked portfolio of exploration opportunities
  • Provide detailed reports with discussion, figures, text, and tables
