Gas Reserves to Production Ratio

World natural gas proved reserves in 2010 were sufficient to meet 58.6 years of global

production, R/p ratios declined for each region, driven by rising production. The Middle East

once again had the highest R/P ratio, while Middle East and Former Soviet Union regions jointly hold 72% of world’s gas reserves

For gas to reach from landlocked Eurasia,

African offshore and Middle east to

consumers, we require trans-national

pipelines and movement of LNG by ships



Major Gas Trade movements

Major trade movements

Trade flows worldwide(bcm)



Natural Gas Trade

Natural gas trade grew by 10% in 2010 with Pipeline shipments growing by 5.4%, led by

growth in Russia, Europe and Eurasia – accounting for roughly two-thirds of global pipeline

LNG trade. driven by strong growth (22.6%) in LNG shipments where exports were dominatedby Middle East, Qatar thus catapulting LNG trade to 30.5% of global gas trade.

E l i d



Energy supply investment pursued

vigorously

Sustained investment required to combat the decline in output at

existing fields, which will drop by almost two-thirds by 2030

Additional capacity of 4 times current Russian capacity needed by 2030

to offset decline at existing fields & to meet increase in demand

leading economies (~1300 kg China & 7,800 kg USA)

• Integrated Energy Policy (IEP) expects the growth in PCEC to quadruple by 2030 – but gas

Processing



Produced from Rajasthan block, this crude

is a medium API, highly viscous having

abnormally high Pour Point (only 2 crudes

have more pour point) AND

with a very high residue

Natural Gas – Well head to End user

Bird’s eye view

Natural gas produced in associated or free form is

first processed at the Group gathering station or

process platform before further processing at a gas

processing plant to produce value added products



Gas Production

OnshoreThere can be two type of gas

sources namely associated gas

which comes dissolved with oil -

usually rich gas AND free gas

which is derived from a an

exclusive gas pay zone which

may or may not be rich gas

Shale

Gas Production



Gas Production55 MMSCMD gas is produced from Bombay offshore at a water

depth of 50-75 m where 40 MMSCMD gas produced from KG

Basin at a water depth between 700 m to 1700 m

Today we have gone in ultra deep water(>5000 ft) with

producers upto 10,000 ft and feasibility of laying pipelines

beyond 15,000 ft water depth (proposed Oman-India gas

pipeline)



Gas Shales

• Shale gas is gas produced from organic

rich shale rock with very low rock

permeability and as such were

uneconomic to develop due to very

low production rates. However,

horizontal drilling techniques

combined with multi-stage hydraulic

fracturing has helped to achieve

economic rate

•Common traits of gas shale reservoirs – Abundant gas (up to 400 Bcf/m2)

– Large developments (economies of scale)

– Large and numerous hydraulic fracs

–

Long well life (60-year reservescommon)

Shale gas – efforts in India

ONGC in collaboration with Schlumberger has undertaken

an integrated pilot project to drill 4 wells, 2 in Raniganj,West Bengal and 2 wells in North Karanpura-Jharkahand to

find potential of Shale gas in Indian basins

First well proved presence of

Shale gas on 25th January 2011

To Conclude



To Conclude

Price acceptability of Indian consumer at higher crudeprice linked to present fuel conversion price

Significant potential in growth of per capita energy with

power, fertilizers, CGD(industrial) segments the main driver

Difficult to maintain price protection & gas allocation as itmay affect realization to the producer

Power and Fertilizers to continue to be major consumers –

accounting for 64% of the total demand by 2015

Gas Grid development essential to open new demand areas

Indian consumer to afford higher energy price to satiate the

shortfall in future
