Seismic Data Processing:

DGH is maintaining a Seismic Data Processing Center with limited capacity. It consists of Sun V880 server, running on Sun Solaries operating system. It is equipped with most of the drives required to read data from any media. It has Paradigm suite of software. With a small team associated with the center, the system is being used for Seismic Data Management, Data preparation for NELP rounds, giving training to Graduate Trainees and for some special reprocessing for value addition. Presently under Basin Integration Project some old vintage data of UP and Bengal basin is being reprocessed to get a regional view of the basin. The system is expected to be upgraded this year to have state-of-the-art technology. Every year two Graduate Trainees selected from various universities are trained in DGH Processing Center. Within a year they get opportunity to work with National or Multi-National companies. DGH is providing trained Geoscientists to the country.

Seismic Data Interpretation:

The environment for petroleum exploration and production has placed intense focus on the need for increased efficiency in the work processes such as seismic interpretation, building 3-D reservoir models, petrophysical interpretation and reservoir simulation. Directorate General of Hydrocarbons is having integrated working environment of geologist, geophysicist, reservoir engineer and drilling engineer with state of art technology to take care of seismic interpretation, 3D reservoir modeling, petreophysical interpretation, simulation and well designing. The systems works hybrid environment of Unix, Linux and Windows operating system with industry experience manpower and standard geoscintific software Geoframe, Landmark, Petrel, Elanplus, Interactive petrophysicist, Eclipse etc from world renowned software supplier. 

Visualisation:

The cutting edge 3D Visualization technology was introduced to PSC with the commissioning of the Virtual reality Center in April 2008.With this technology, geoscientists can analyse and interpret seismic data, well logs and reservoir properties simultaneously, “walking through” a 3D representation of underground rock structures. 

Interpreters can scan multi-attribute/ multivolume seismic, well and cultural data, and reservoir models. 

This breakthrough technology can be utilized to facilitate review of development plans, locations and related G&G aspects. The 3D volume visualization will aid the team of Geoscientists to accelerate the workflow of evaluating the proposals for exploratory and development locations, Commerciality declarations, Appraisal programs, Development plans submitted by the Operators for various PSC blocks.
