FUNCTION & RESPONSIBILITIES
• Advisory Functions to Government.• Acreages• P S C.• Data Acquisition.• Processing.• Interpretation.• Visualisation.• Drilling activities.• Petro-physical Activities.• Reservoir Monitioring, & Other Activities.
E & P ACREAGES
• DGH’s responsibility in Indian E&P acreages.
• India’s Sedimentary area . { 3.14=1.35 + 1.79 }
• Active petroleum Exploration Licenses.
• Under Mining Lease.
Production sharing contracts(PSC)
Following activities are being carried out in PSC :-
• Review of work Programme and budget.
• Facilitating of statutory and other clearances.
• Management Committee Meetings.
• 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
Environment & Safety• Need to minimize adverse effect on the environment.
• DGH ensures all mitigating efforts for protection of environment.
• The PSC stipulates for protection of the environment under its Article 14.
Enforcement of the following by the contractor:
• Contractor shall conduct its Petroleum operations with respect to protection of the environment and conservation of natural resources.
• 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:
Legal Advisory :
• Legal opinion on the issues referred to legal section in connection with various activities
being undertaken by DGH.
• Vetting of Contracts and (MOU).
• Drafting of correspondence with contractors in connection with various issues being raised by contractors under PSC’s.
