4 4 Agenda item No.2: Presentations on summary of the work carried out by the Member Organizations 2.1. Oil and Natural Gas Corporation Thiru. Jayanta Sarkar, Deputy General Manager (Geology) Oil and Natural Gas Corporation gave a brief introduction of the earlier activities of ONGC and progress of work carried out in Tamil Nadu during the period from to Progress of work carried out during to During the period, 8 rigs were deployed and 21 number of wells were drilled. Out of the 21 wells, Oil and Natural Gas has been identified in 15 wells and remaining 6 wells were abandoned. The Deputy General Manager, ONGC has informed the house that a royalty of Rs crore has been remitted by the ONGC for the production of MMSCM of Natural Gas and 2,40,063 Metric Tonnes of Oil during the period from to Progress of work carried out during to During the period 7 rigs were deployed and 20 wells were drilled. Out of the 20 wells, Oil and Gas has identified in 13 wells, one well was inconclusive and remaining 6 wells were abandoned. The Deputy General Manager, ONGC has informed that a royalty of Rs crore has been remitted by the ONGC for the production of 1, MMSCM of Natural Gas and 2,54,095 Metric Tonnes of Oil during the period from to Progress of work carried out during to During the period 7 rigs were deployed and 9 wells were drilled. Out of the 21 wells, Oil and Gas has been identified in 5 wells, one well was inconclusive and remaining 3 were abandoned. The Deputy General Manager, ONGC has informed that a royalty of Rs crore has been remitted by the ONGC for the production of MMSCM of Natural Gas, and 1,46,779 Metric Tonnes of Oil during the period from to

5 The Deputy General Manager, ONGC has presented the salient features of the work carried out by ONGC: a. A total of eighteen exploratory and thirty two development wells were drilled during this period to b. An inplace accretion of MMtOE has been achieved in the period to The Deputy General Manager has also appraised the critical issues faced by ONGC regarding the public having misconceived notion that ONGC is engaged in CBM / Shale Gas exploitation, thereby stiff resistance to ONGC s activities have increased in the recent past. Since October 2015, ONGC Rigs have been barricaded by the agitating elements and currently, in 3 rigs drilling activities have come to a halt. Further, 3D seismic acquisition planned in Manakkal area had to be called off and planned HF jobs in wells MY-1 & 2 was stopped by villagers. Conducting Public Hearing for environmental clearance is often disrupted. Land Acquisition has become increasingly difficult as petty land owners are reluctant to part with their land. Civil works (related to site preparation) were stopped. Further, plan to monitor a few prospect were derailed apart from enormous financial loss to ONGC. Expediting the grant of Madanam mining lease was requested as it will increase oil production steeply. In Ramnad area, laying of new Gas transportation pipeline will result in increased Gas production. However, non-issuance of wild life clearance at State board level is delaying the award of consent to operate (CTO) from State Government, so that the exploratory and drilling plans of Cauvery Basin/Asset continues to suffer While discussing the various constraints faced by the member organizations, the Commissioner of Geology and Mining has advised the ONGC officials to co-ordinate with district administration prior to any operation so as to convince the local people about the activities to be undertaken and highlight the compensatory measures for involving such lands and also

6 6 suggested to have a separate wing in ONGC for good coordination with District administration and local authorities. With regard to the request of ONGC to expedite the grant of mining lease in Madanam area, the Chairman has assured that the Government will take active steps in the disposal of the mining lease application. The Chairman requested all the Board Members to carryout the geological investigation works in future only after notifying the same by the State Government as mandated in the Act and Rules and also requested for better co-ordination among the member organizations. 2.2 Geological Survey of India Dr.S.Raju, Dy.

15 The Deputy Manger, (Mining Lease) of TAMIN has informed that the total sale of minerals like Granite, products of granite, graphite, vermiculite, limestone, etc. by TAMIN during is Rs lakhs. The contribution of TAMIN to Government during is Rs.1, lakhs and net profit is Rs,1,499/- lakhs and profit before tax is Rs.2,306 lakhs Central Ground Water Board The Scientist-D, CGWB has informed that Groundwater level monitoring is being carried out 4 times in a year (May, August, November and January) throughout the State by the CGWB. In total 1439 wells are being monitored (Dugwells: 869 Peizometers:570) and the groundwater quarterly bulletin is circulated to all the line State Government departments. As part of the CGWB activities Groundwater Quality Monitoring - Hydrochemistry is being carried out. In this Groundwater samples are collected from the monitoring wells during premonsoon period (May) every year and are analyzed for major and minor ions including Fluoride and Nitrate. Also, groundwater samples are analyzed for heavy metals for special pollution studies. During the period, 3264 nos. of groundwater samples have been analyzed in the CGWB, SECR, Chemical Laboratory, Chennai. The analyzed groundwater quality data have been used for aquifer mapping. Groundwater Pollution Studies were carried out in the Industrial Clusters of Coimbatore, Tiruppur, Erode, Mettur, Manali, Vellore and Cuddalore and the report were shared with the State Government departments In the course of Geophysical Studies, Surface Geophysical Investigations for Aquifer Mapping: 411 (Vertical Electrical Sounding) is being carried out by CGWB and in this Subsurface Geophysical Investigations such as Resistivity Logging in pilot boreholes drilled during groundwater exploration in soft rock areas and Resistivity logging were carried out in hard rocks to decipher the fracture zones. Groundwater (Dynamic) Resources Estimation is being carried out by CGWB. The Dynamic Groundwater Resources assessment as on March 2013 was carried out for the State of Tamil Nadu (1139 firkas) and the

16 16 assessment is repeated once in two years. For the State of Tamilnadu, the exercise was carried out jointly by CGWB, Government of India and State Ground and Surface water Resources data centre, PWD, Government of Tamil Nadu. The report (March 2013) is approved by State level committee and submitted to central level committee for approval Under Hydrology Project aquifer mapping was carried out in parts of lower vellar water shed, Cuddalore coastal aquifer system. Exploratory wells were drilled to demarcate the vertical and lateral extent of multi - aquifer system occurring within the Cuddalore coastal aquifer system. Piezometers tapping the different aquifer (I, II, III, IV) were constructed and monitored monthly. It is inferred from the study, that multi-layered aquifer system exists (ie. 4 aquifer units) within the pilot project area (Lower vellar water shed, Cuddalore dist). The study has been successfully completed and report is available for implementation to user agencies. Numerical modeling study carried out by CGWB revealed the aquifer is under stress due to industrial and agricultural pumping. Further, the study reveal any pumping activity from coast to 10km inland should be monitored and piezometric head/water level should also be monitored continuously. Heavy and continuous pumping in these zones shall invite sea water intrusion; the study concluded that Cuddalore coastal aquifer system is the most potential aquifer in the State. Aquifer management Plan has been developed for the Cuddalore coastal aquifer system. As the peizometric head near the coast had declined from ground level to 30 m below mean sea level, pumping in these zones shall invite sea water intrusion National Aquifer Mapping is being carried out in three aquifer system viz., Upper Ponnaiyar Aquifer system, Upper Cauvery Aquifer system and Amaravathy aquifer system. The aquifer mapping study involves integration of ground water related data, identification of data gap, deciphering the vertical and lateral aquifer system. The representatives from ONGC have enquired whether the CGWB has any map showing the ground water contamination of Fluoride, Selenium and

17 17 Arsenic. In this regard, the Scientist D has informed that CGWB having map showing fluoride contamination in the ground water State Ground and Surface Water Resources Data Centre Board Thiru P. Chandrasekar, Assistant Director, SG & SWRDC informed that Ground Water Level monitoring is being carried out by this department every month from 3170 observations wells and 1558 piezometers from entire Tamil Nadu. He appraised the studies of the departments on various maters like, Water Quality, Sea Water Fresh Water interface study, Re-assessment of Replenishable Ground Water Resource, and other activities like Ground water Clearance (NOC), Consultancy services rendered to farmers, general public, industries and Government Departments and Data dissemination Water Quality: Water Quality analysis is being carried out from 2482 samples (Yearly Twice) collected from the Ground water wells for Pre monsoon and Post monsoon period every year. In this analysis 36 parameters are being analyzed including major Ions and Pollution parameters Sea Water Fresh Water Interface Study: Sea Water Intrusion study has been systematically carried out from 2007 onwards by this department for the coastal length of 1076 Km in Tamil Nadu. For this study, water level is being taken from 224 wells located in the coastal belt every month exclusively and water samples are collected for Pre and Post Monsoon periods Re-Assessment of Replenishable Ground water Resources: Based on the data collected from different methods, the availability of Dynamic Ground Water Potential is assessed as per the norms issued by the Ground water Estimation Committee (GEC) 1997 in coordination with Central Ground water Board (CGWB), Government of India. The ground water Assessment was carried out for every two years, taking revenue firka as a Unit, instead of Blocks, from 2011 onwards. Accordingly 1129 revenue firka falling in

18 18 32 districts of the State is categorized as 374 over exploited, 48 critical, 235 semi critical, 437 safe and 35 as saline firkas as per 2011 assessment. The Assessment for the year 2013 and 2015 are under progress. Government of Tamil Nadu has banned the ground water development in over exploited and critical firka Ground Water Clearance (NOC): For ground water clearance is being issued by this department for the water based and non water based industries located in the safe and semi critical firka by adopting the spacing norms between wells and the quantity of water available is assessed by conducting Pumping test as per Government Orders Consultancy Services: Consultancy Service is being rendered to farmers, general public, Industries and Government departments for selecting suitable site for drilling borewells / digging open wells based on the Hydro geological and geophysical Survey results.
