We have no
alternative but to
develop Shale Gas
resources of the
Country
As per earlier figures compiled in
DGH the production of
Conventional Gas in India is
likely to decline after 2015.
Therefore, Shale Gas will be the
only Domestic Source of Gas
availabile in India, in the near
future.
India’s conventional supplies decline after 2015

• As per working group of Petroleum & Natural Gas
(2012-17) the Domestic Gas Production during the
period 2016-17 to 2021-22 will not increase
significantly.
• The demand for gas in the country will be met by
import of LNG to the tune of 101 MMSCMD i.e.
40% of then demand in 2013-14 and will increase
to 163 MMSCMD i.e. 45% of then demand
expected in 2016-17. Thereafter, the country may
import both LNG and cross-country piped gas to
the tune of 288 MMSCMD or 57% of then demand
in 2017-18 to 2021-22.
• This is a very serious situation as during the
period 2025-2030 the import of Crude Oil may
reach 90% and import of Natural Gas can be over
60%.

Based on IEA’s World Energy Outlook
2009 India’s incremental Carbon Footprint
between the period 2007-2030 will be 2035
MT Co2 /Annum. Incidentally, this + 153%
increase over 2007 will be the highest for
any major country in the world. In contrast,
the figures for USA, Europeon Union and
Japan are respectively -4%, -10% and 20%. As we produce more gas in the
country, the Carbon Footprint will
dramatically improve.
India needs to manage its carbon footprint

As per IEA’s World Energy Outlook 2009,
India’s Oil & Gas import by 2030 would
be over 300 billion USD in 2009 terms.
In addition, about 70 billion USD may be
used to import LNG and piped gas from
abroad. India will be only major country
in the world investing 6.5% of its GDP on
Oil & Gas imports. Figures for China,
Japan and European Union the other
major importing regions would be
respectively only 3.5%, 3% and 2.5%.

Indian economy and foreign
exchange reserves cannot
sustain the projected, future
energy imports. Therefore,
early
development
of
Domestic Shale Gas/Oil is
essential.

THEN ENTER INTO MODEL CO-DEVELOPMENT /
OPERATING AGREEMENT FOR SIMULTANEOUS
EXPLORATION AND PRODUCTION.
•
GOVT. WILL ENSURE ALL STATUTORY, REGULATORY AND SECURITY
CLEARANCES ARE OBTAINED BEFORE BIDDING
•
EXPLORATION WILL BE AN ACCORDANCE WITH THE LAW OF THE LAND,
INCLUDING THE WATER ACT 1974, AIR ACT, 1981 AND UNDER
ENVIRONMENT PROTECTION MEASURES

COMMITTEE OF SECRETARIES. THEREAFTER, FINAL APPROVAL BY CCEA.
•
PROVISION FOR ADDRESSING WATER MANAGEMENT ISSUES AND OTHER
ENVIRONMENTAL ISSUES.

• CONTRACTOR WILL PAY ROYALTY TO STATE GOVERNMENT.
• CONTRACTOR TO BID PRODUCTION LEVEL PAYMENT (PLP) ON A
SLIDING SCALE BASED ON INCREMENTAL PRODUCTION.
• COST RECOVERY WILL NOT BE ADMISSIBLE.

• NO CESS PAYABLE ON SHALE OIL
• TO PAY APPLICABLE INCOME TAX AS PER INCOME TAX ACT 1961.
• THE GAS PRICING MECHANISM WILL BE UNDER BROAD DIRECTIONS
OF GOVERNMENT POLICIES.
Suggestions on Draft
Policy to attract
Technology
&
Investment
•Suggestion 1
Draft Policy states pricing of gas will be within the
framework of the Govt. Policies on Marketing and
Pricing of Gas.
This will be the main stumbling point in the shale gas
policy. Because Shale gas wells are drilled deeper,
drilled horizontally with multi stage fraccing, they
need huge quantities of water and proppants,
therefore, they cost 2-3 times more than conventional
wells. Without market driven price many wells will
not get drilled as per the experience of USA.
Experience of USA – maximum number of rigs
operate and maximum wells get drilled when shale
gas price is high.
•Suggestion 2
In the draft policy no income tax or fiscal
incentive provided.
It is suggested that at least in the first round of
Shale Gas to attract Companies with requisite
experience, technology and financial strength
some incentives may be considered.
Reasons
1. Interest of companies is fading in India.

Reasons (Contd.)
2.
Very high cost of Shale Gas development (23 times more than conventional hydrocarbons).
3.
Lack of infrastructures available in the
country for shale gas. Very limited pipeline
network.
4.
Lack of sufficient sub-surface data which
will discourage private companies specially
foreign companies from investing due to
conceived high geological risk.
5.
Limited unconventional E&P experience in
the country.
6.
Very poor land and fresh water availability
being densely populated country.
Reasons (Contd.)
7.
Shale Gas production from very tight shales is
a highly complex and technically challenging
process. It will be necessary to provide incentives to
attract experienced oil companies with technologies
from abroad and also to encourage Indian companies
to invest money in this new kind of use of
technology, in a country where commercial presence
of shale gas is not yet established.
8.
According to EIA publications, April 2011 there
are 32 countries having 48 major Shale Gas Basins in
the world. Thus, India has to compete with many
countries to attract suitable Companies which can
bring technology, capital and management
capabilities.
India is competing with other countries to attract companies with shale gas
experience that will bring Technology, Capital & Management capabilities

India: 63* TCF
Reasons (Contd.)
9.
When NELP and CBM Rounds introduced for the first time, the
Government provided 7 year tax holiday to attract companies to bid in
India. Now that even more complex and technology intensive Shale Gas
Policy is being announced it may be necessary to again consider 7 years
tax holiday.
10. If above is not feasible then a case should be build up for atleast 4 –
5 years tax holiday.
Shale gas wells decline very fast. To maintain production at reasonable
level for sale to industry, wells have to be drilled every 2 – 3 years
It is estimated that in 4 – 5 years only around 20% gas may get produced
out of entire life of field on which tax holiday will apply. This model can
be developed by DGH. The Govt. will still earn full tax on remaining 80%
of gas.
The Govt. is getting many other revenues from shale gas block as
royalty, central / state taxes and PLP etc.
•This will provide enormous incentive to drill as many wells as possible in the first 4-5
years and sell gas to consumers as early as possible. This is exactly what country needs
i.e. earliest possible gas production. The remaining 60% wells will get drilled later to
maintain the required production profile for sale of gas.
• Suggestion 3
“3.4
of draft shale gas policy states that areas
previously allotted and where development /
production phase has started shall be excluded from
offer for shale gas / oil exploration.”
Such areas in Cambay, KG, Cauvery, Damodar &
Assam- Arakan Basins hold the best shale gas/ oil
potential of the country. Thus, 60-70% of expected
resources will not get developed.
• Some options for considerations –
(a) When such blocks are offered and if the existing
operator of an oil & gas Block is the best bidder he will
automatically get the Block. If he is not the best bidder
then option is to give him a chance to match the best
bid. This could be unfair to the new bidder. It may be
better if the block is awarded to the best bidder but
original operator of Oil & Gas Block is given an option
to farm in upto 30% in the operations of the new bidder,
on payment basis.
(b) Ministry by transparent bidding process may allow
current lease holders of oil & gas blocks to download
part of their equity to companies with shale gas
experience and technology.
•Suggestion 4
In draft policy contract duration is 32 (thirty two) years and
divided into two phases- Phase I and Phase – II
•
Division in Phase-I & Phase-II may not be adequate. For
example in CBM Contracts there is minimum provision of 3
Phases and past 14 years of experience of CBM operations in
India shows that 3 phases are required.
Following phases and time frame may be considered:
•
•
•
Phase-I (5 years) – Exploration Phase with provision for
Exit at its end, if required.
Phase-II (minimum 3 years) – This can be called Drilling
of Pilot Wells Phase. Also includes Techno economic
feasibility, Market Survey and Commitments. With an
exit clause at its end
Phase-III (25 years) – Development & Production Phase
•Suggestion 5
•Bidding Parameters in draft policy
•Technical Qualifying Criteria– 3 years experience in oil & gas / CBM/
shale gas / oil.
•Weightage for Minimum Work Program – 40%
•Weightage for Production Linked Payments – 60%
•This will not give desired results based on the experience of pre-NELP
and NELP Rounds in the last 20 years. What could be considered–
