India's Hydrocarbon Outlook – 2022-2023

122 DGH: 3 DECADES OF UNLOCKING INDIA'S HYDROCARBON POTENTIAL Decline Curve Analysis: Use Multiple Plots Reservoir Simulation: To use for reserves the model must be thoroughly vetted Established history match at the field, area, and well levels for all phases of production, injection, pressure etc. Geologic model must be current using all available data Noanomalies suchas flowbarriers, highperm streaks, unusual adjustments of engineering parameters to gain the history match, tuning of wells of wells on and off (should match actual operational procedures) etc. Simulation models can be used in conjunction and cross checked with other methodologies (Material Balance, Decline Curve Analysis and with Analogue field recovery factor) Courtesy: Presentation by D&M in “DGH PRMS workshop in collaboration with D&M – 10-12 January 2023” Petroleum Resources Management System (PRMS) in DGH: Previously, Reserves & Resources were being reported at Directorate General of Hydrocarbons (DGH), using a generalised methodology not following a standard format. In the last one and half year, significant efforts have been made to fully implement Petroleum Resources Management System (PRMS) in DGH. In this regard, DGH has issued several directives to Exploration and Production(E&P) companies for adoption of PRMS standard. This enjoins that all hydrocarbon discoveries must be declared and reported in accordance with the guidelines set forth by the PRMS, approved by Society of Petroleum Engineers in June 2018 and as amended from time to time.
