Reserve Analysis

Reserves Analysis – Resource Reservoirs

  • INEXS engineers determine the asset acreage and identify all wells on and surrounding the acreage that have penetrated or produced from the objective reservoir.
  • For producing wells – proved developed producing – careful decline curve analysis combined with accurate determination of the economic limit of the production will yield the recoverable reserves per well.
  • For proved undeveloped well locations, the team then constructs type curves based on decline curve analysis of the production from a selection of wells, resulting in one or multiple type curves for each reservoir.
  • The team determines the economic constraints associated with each new well including the drill and completion costs, the lease operating expenses, the processing, gathering, transportation, and basis differentials to define the economic limits of production.
  • The proved, probable, and possible reserves are tabulated and presented to the client for review, further discussion, and modification if warranted.
  • This data is presented back to clients in easily understood formats to help them make informed decisions.

Reserves Analysis – Conventional Reservoirs

  • INEXS engineers determine the reservoir drive mechanism(s), porosity, permeability, water saturation, oil/condensate/gas/water contacts, GOR, and heterogeneity of the reservoir to determine the original oil and gas in place, then compare to offset fields and production to determine production analogs, and drainage/sweep efficiencies as well as cumulative production to date to determine the remaining producible reserves.
  • For reserve auditing and reporting, INEXS complies with SPE and SPEE standards.
