After the discovery of the giant Bombay High and numerous onshore fields already on production, there was a need to address the issues of reservoir management. The Institute of Reservoir Studies (IRS) was established at Ahmedabad on 18th May 1978 with the objective to develop and apply reservoir engineering techniques to maximize hydrocarbon recoveries through proper reservoir management of oil & gas fields.

IRS, an ISO 9001:2015, ISO 14001: 2015, ISO 45001: 2015 certified R&D Institute is the nodal agency for formulating the development schemes of oil and gas fields of ONGC with state of the art Data Centre to carry out seismic to reservoir simulation. The emphasis is on Integrated Reservoir Management combining Seismic, Geological, Well logging, Reservoir and Production. It works as a premium agency with modern laboratories facilities to prepare long-term strategies for field development and EOR (Chemical, Thermal and High Pressure Air Injection) applications, design, commissioning and monitor EOR processes in mature fields to enhance secondary and tertiary recoveries.
