Veerappa Moily, the Petroleum and Natural Gas Minister on 20 January 2014 announced to set-up a Multi Organisation Team (MOT) to carry out re-assessment work of hydrocarbon resources in 26 sedimentary basins.
The re-assessment will be done to highlight the oil and gas potential of India and has been given a time limit of 30 months to prepare basin wise portfolio in light of the oil and gas discoveries since 2001. It has been asked to estimate the resource of all 3.14 million square kilometers of India. Resource assessment will be carried out at Keshav Dev Malviya Institute of Petroleum Engineering (KDMIPE) of ONGC in Dehradun. The work done by the institute will be reviewed periodically by the National Steering Committee. The panel will be headed by the Oil Secretary and will include the Director General of Hydrocarbons, exploration heads of ONGC and OIL and the head of the KDMIPE.
The International Energy Agency (IEA) in 2013 estimated that India’s oil and gas resource potential is of 206 billion barrels of oil and oil-equivalent gas. Last such exercise of 15 sedimentary basins was carried out about two decades back and its full revision is overdue because of the vast amount of data collected during the exercise.
The oil ministry statement has said that the MOT will comprise exploration heads of ONGC (Oil and Natural Gas Corporation) and Oil India limited. It will also have an official from the Directorate General of Hydrocarbons (DGH).
The re-assessment and revisit of the Hydrocarbon Resource of India is required following the quantum jump in the availability of geo-scientific data that was generated under the New Exploration Licensing Policy (NELP).
New Exploration Licensing Policy (NELP)
The New Exploration Licensing Policy (NELP) was launched by the Government to accelerate the pace of hydrocarbon exploration in the country. So far two rounds of NELP have been announced.
Terms of Reference
• Resource estimation exercise will be carried out for all the 26 sedimentary basins of India. The total sedimentary basin area is 3.14 million Sq. kms.
• Preparation of sedimentary basin and sub-basin wise portfolio of available technical data and indicating the future data requirement/generation in unexplored sedimentary basins/sub-basins for their Hydrocarbon resource assessment.
• Within the basins, comprising sub-basins and/or sectors, the hydrocarbon resource figures are to be worked out for smallest possible units within a basin.
• For basins with vertically stacked multiple petroleum systems, resource estimation is to be attempted separately for each petroleum system/source rock.
• Preparation of detailed maps with exact delineation of basin/sub-basin boundaries & basin/sub-basin areas based on the latest available Geo-scientific data of all types.
• Review the present parameters used for categorization of basins and suggest changes, if needed, for re-categorization of basins.
• The work of hydrocarbon resource assessment will be carried out under the leadership of KDMIPE, Dehradun. Multiple work executions teams will be established for the purpose, as required.
• KDMIPE my engage expert bodies and consultants as required for the arrangement as per standard ONGC procedure.
• Since the Resource assessment of all the basins cannot be done simultaneously, the work execution teams will prioritize and draw timelines for completion schedule for each Basin, so as to complete the total exercise including report writing within a time frame of 30 months.
Multi Organization Team (MOT): To ensure data confidentially and quality output in the desired time frame, a Multi Organization Team (MOT) that will comprise of
• Director (Expl) ONGC: Chairman
• Director (Expl & Dev) OIL: Co-Chairman
• Head, KDMIPE ONGC, Dehradun: Member
• Head, R&D OIL, Duliajan, Assam: Member
• GM (G&G) DGH, Noida: Member
The process of Hydrocarbon resource estimation of different basins being sequential, there will be quarterly review meetings by MOT for assessing the progress. Comprehensive documentation in the form of various reports and maps will be generated. The detailed modality of generation of documents and maps will be decided by the Head, KDMIPE, Dehradun and Head (G&G), DGH, Noida. The MOT may meet at more frequent intervals, if required.
Geo-scientific data for the study: KDMIPE will utilize the geo-scientific data available with them and DGH for propose of resource assessment. DGH will be responsible for providing all the resource assessment related data of NELP and pre-NELP blocks, operated by various E&P companies. Data confidentially will be maintained by KDMIPE.
