The reserves estimation process is one in which the Oil and Gas Initially in Place and recoverable volumes are estimated
using either Volumetric, Material balance or Numerical simulation methods.
The process is repeated periodically throughout the
producing life of an asset. Updates to reserve volumes are typically due to improved geological understanding of the reservoir
substructure or sufficient production history to support a re-assessment of reserves.
The purpose of reserve estimation is to plan future asset development, and keep stakeholders and government regulators
abreast of the company’s status. Reserves estimation at this company was done using the volumetric method.
