• Assignment of Participating Interest. • Other PSC related issues as and when arise.

Data Acquisition

Objective :-Surveys undertaken by DGH :-{total area of 2 million sq kms , 84% is in offshore and

16% in onland.} Satellite gravity surveys- 1.642 million sq. kms. (82%). Geochemical surveys Shallow offshore geochemical surveys Integrated geophysical surveys, Aero-magnetic surveys.

SURVEY TOOLS

Processing

• Seismic Data Processing Center.• It consists of Sun V880 server, running on Sun

Solaries operating system. • Used for :- Seismic Data Management, Data preparation for NELP rounds, giving training to Graduate Trainees and for some special Reprocessing for value

addition:- under Basin Integration Project.

Interpretation

Visualisation• Commissioning of the Virtual reality Center in April 2008.– “walking through” a 3D representation of underground

rock structures.

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

• To facilitate :-• review of development plans, locations and related

G&G aspects. • aid the team of Geoscientists.

Drilling activities

• Monitoring of Drilling activities in Onland and Offshore wells of NELP Pre-NELP blocks/fields.

• To prepare various data related to rigs and wells. • Evaluation of drilling work programmes and budgets for all

blocks and fields. • Evaluation of all EC applications related to drilling wells,

rigs,OSVS etc. • Estimation of cost of unfinished drilling work programme of

operators.• Technical scrutiny of all matters related to drilling/workover

activities.

Petrophysical activities

Involved in Independent analysis of wells in blocks under NELP,PRE NELP,Producing Field and nomination acreages with National Oil Companies. The broad activities are as follows:

• Quality control checks and evaluation of well logs for estimation of thickness, porosity, saturation and identification of fluid contacts to establish reservoir limit & properties of fluid type.

• Evaluate production logs recorded in producing fields to monitor the reservoir health.

• Estimation of logging cost for unfinished work program of operators.

Reservoir monitoring

• Evaluation of initial testing in a new discovery of hydrocarbons. • Evaluation of initial development plans and proposal for

additional development plans. • Review of annual work program of PSC’s related to reservoir

activities.• To ensure sound Reservoir management practices . • Monitoring the performance of EOR schemes under

implementation. • Framing of long term production profiles of new NELP blocks.• Other miscellaneous activities.

Other activities

• Assisting Government in formulation of Hydrocarbon related revenue policies.

• NELP & CBM Bidding.• Economic evaluation of –Development Plans–Commerciality of discoveries

• Review of :-Annual Accounts

Cost recovery

NATIONAL CO-OPERATIONS

At the national level, DGH has embarked on the following :

•Upgrade and modify the earth science curriculum to cater to the increasing needs and demands of the E & P industry. •Three brainstorming sessions.• 5 National Working Committees have been formed.•Various projects at National level have been initiated through various Institutions

INTERNATIONAL CO-OPERATION

At the International level DGH has signed MOU with Alberta Research Council of Canada Energy Resource & Development Unit of Department of Trade & Industries of UK Norwegian Petroleum Directorate of Norway Research Institute of Petroleum Exploration & Development of China University of Aberdeen of UK Imperial College of London UK Department of Industry & Resources of Australia Japan Oil, Gas & Metals National Corporation of Japan The Korea Institute of geology, mining and materials Republic of Korea United States Geological Survey United States Department of Energy

• Employ modern oilfield and industry practices and standards including advanced techniques of operation for the prevention of environmental damage in conducting its petroleum operations.

• Adequate compensation for injury to persons or damage to property caused by the effect of petroleum operations.

• Comply with the requirements of applicable laws and the reasonable requirements of the government from time to time.

• DGH coordinates with MOEF, CPCB and other concerned organizations on environmental issues and also assists MOP&NG on such matters.

• Environmental Impact Assessment studies:

Hazards • Major Oil & Chemical spillage • Routine or Accidental discharges of waste • Blow - outs / Explosion • Flaring of Gases • Improper disposal of Effluents generated • Land subsidence & Wetland Losses

Enforcement of the following by the contractor:
