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
01.04.2014 to 30.09.2016.
2.1.1 Progress of work carried out during 01.04.2014 to 31.03.2015
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.272.10 crore has been
remitted by the ONGC for the production of 1191.57 MMSCM of Natural Gas
and 2,40,063 Metric Tonnes of Oil during the period from 01.04.2014 to
31.03.2015.
2.1.2 Progress of work carried out during 01.04.2015 to 31.03.2016
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.205.83 crore has been remitted by the ONGC
for the production of 1,010.247 MMSCM of Natural Gas and 2,54,095 Metric
Tonnes of Oil during the period from 01.04.2015 to 31.03.2016.
2.1.3 Progress of work carried out during 01.04.2016 to 30.09.2016
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. 79.67 crore has been remitted by the
ONGC for the production of 463.134 MMSCM of Natural Gas, and 1,46,779
Metric Tonnes of Oil during the period from 01.04.2016 to 30.09.2016.

2.1.4
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 01.04.2014 to 30.09.2016.
b. An inplace accretion of 37.41 MMtOE has been achieved in the period
01.04.2014 to 30.09.2016.
2.1.5
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.
2.1.6 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
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.

2.6.0. TAMIL NADU MINERALS LIMITED
2.6.1
Thiru E.Ganesan, Deputy Manger, (Mining Lease) of TAMIN presented
about the Molybdenum Project and M.Sand Project. Regarding Molybdenum
project, he informed that Government of India, Government of Tamil Nadu and
TAMIN have jointly carried out the exploration of Molybdenite in the Vellampatti
south block, Harur Taluk of Dharmapuri District by spending 6.84 Crore.
M/s.MECL has submitted the techno economic feasibility report stating that the
Velampatty south block cannot be viable unless further exploration is done.
GSI, MECL and IBM discussed to conduct further study to establish potentiality
to exploit commercially. The Additional Chief Secretary to Government,
Industries department convened a Joint Meeting with various Government
agencies along with senior officials of IBM, GSI, MECON and TAMIN. GSI has
carried out the Deep Borehole Drilling work at Uttangarai and submitted the
report to TAMIN on “the Reconnoiter Exploitation for Molybdenum in the
extension areas of Uttangarai Sector covering 14.45 kms in 3 sub areas.
Based on the recommendations of GSI, MECL had opened an exploratory mine
on behalf of TAMIN in the southern part of HUB in Velampatti south Block. GSI
established 3 controls viz., 1. Zone of Shearing (ZoS) [23 km x 100m - 250m]
consists of (a) Main Shear zone (b) Synthetic shear Zone, 2.Quarz vein/reef,
3. Shear foliation and fracture planes surrounding the Quartz vein/ reef.
2.6.2
M/s. MECON submitted the Feasibility Report that the mineable reserve
has been assessed as 1.01 million tonnes with a mine capacity @225 tonnes
14
per day by floatation technique. The life of the Molybdenum will be lasting for
15-20 years. As suggested by M/s. MECON that the project needs an
investment of about Rs.53 crore for 225 tonnes per day plant and the
implementation will be taken a minimum period of 27 months from zero date.
Hitherto, a total sum of Rs. 6.84 Crs have been spent. (Government of India :
3.92 Crore + Government of TamilNadu : 1.80 crore + TAMIN : 1.12 crore =
6.84 Crore] GSI is of the opinion that further investigation can be taken up in
the interest of the nation to prove the Molybdenum reserves as well as viability
of the Project. While concluding the meeting by Additional Chief Secretary to
Government Industries Department it was informed that further funding from the
State Government is not possible considering the viability of project at this
juncture. It was decided to address to the Ministry of Mines, Government of
India, emphasizing the need for further explorative works to be carried out by
GSI, MECL at Harur taluk, Dharmapuri district.
2.6.3
While appraising about the M-Sand Proposals, he informed that TAMIN
proposed to set up manufactured sand factories in 4 different parts of State.
M/s.ITCOT, Chennai has been awarded to study and submit a technical and
economical feasibility report in M-sand. The Board of TAMIN while noting the
feasibility report of M/s. ITCOT Ltd, desired that the proposal be submitted to
Government for approval, for implementing the project through a public private
partnership / Joint Venture mode in four different parts of the State. TAMIN
identified charnaockite quarries in S.F.No.194/1 of Reddiyarpatty village,
Alvarkurichi village, Tirunelveli District. Mahindravadi in Vellore District,
Suriyanagaram in Tiruthani Taluk, Tiruvallur District, Vellithangipuram in
Arakkonam Taluk, Krishnasamuthiram, Kattukuppam, Karnavur and
Kuthampakkam in Vellore District for manufacture of sand. The Board of
TAMIN has directed to look into various aspects of implementing the project
through PPP mode and the estimated total cost of project excluding working
capital Rs.1415 lakhs.
15
2.6.4
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 2015-16 is Rs.14934.01 lakhs. The
contribution of TAMIN to Government during 2015-16 is Rs.1,718.65 lakhs and
net profit is Rs,1,499/- lakhs and profit before tax is Rs.2,306 lakhs.
2.7.0. Central Ground Water Board
2.7.1
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 pre-
monsoon 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.
2.7.2
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
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.
2.7.3
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.
2.7.4
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
