| Introduction |
| |
The Institute of Reservoir Studies
(IRS) was founded in 1978 as a single-source and multi-service
reservoir engineering agency with the objectives to:
Maximize
hydrocarbon recovery at minimum cost
Provide
holistic reservoir description through integration of all data
Maximize
the value of proven reserves with conventional and improved
recovery techniques
Enhance
the skills and knowledge for better reservoir management |
| |
| Since its inception, IRS has contributed
effectively in the development of new concepts and innovative
techniques besides adopting state-of-the-art technological advancements
as part of its concern. All investment decisions of ONGC regarding
hydrocarbon exploitation are based on the recommendations given
by the IRS. |
|
| |
|
IRS's resources include 12 modern laboratories with latest
equipment supported by comprehensive engineering services.
Over 15 multi-disciplinary teams, for field development planning
and continuous reservoir management, utilize the latest workstations
configured over an institute wide network. A 400 seat Technical
Seminar Hall, equipped with the latest audio-visual facilities
and interpreter desks provides an ideal setup for technical
presentations and conferences. The IRS library contains a
wide range of books ranging from exploration to revenue management.
It also subscribes to various petroleum industry related journals
and magazines. A full set of SPE papers on microfiche and
compact disks are available in the library. Seamless access
to the internet is also available throughout the Institute
through a lease line.
The Institute has been modeled around the concept of 'collaboration
and interaction' to accelerate the process of completing the
studies, improve confidence by using the strengths of latest
software and hardware and increase the accuracy of forecasting.
IRS has a membership and technology transfer agreement with
M/s Computer Modelling Group (CMG) Calgary, Canada.
The Institute also has a technical collaboration for investigation
in High-Pressure Air Injection (HPAI) as Improved Oil Recovery
(IOR) process in medium and light oil reservoirs with the
University of Calgary, Canada.
The activities of the Institute can be broadly classified
into two categories to provide comprehensive solutions:
