1.0 Introduction
Energy, be it conventional or non-conventional is the basic requirement for the mankind. In
present day scenario, the consumption of energy has been increased with the growth of
population and their demand for improved amenities.
In recent days, natural gas has emerged as the most preferred fuel due to its inherent
environmentally benign nature, greater efficiency and cost effectiveness. The demand of
natural gas has sharply increased in the last two decades at the global level. In India also, the
natural gas sector has gained importance, particularly over the last decade and is being
termed as the fuel of the 21st Century.
With the present consumption pattern of hydrocarbon energy, the available reservoirs in the
country will be depleted to a larger extent by the next decade. It is expected that increased
hydrocarbon exploration and production operations can boost up the energy supply and can
help to reduce the supply-demand gap. Keeping the required growth rate and rising energy
demand for hydrocarbons in view, the Government of India has come out with plans to
encourage national, private and foreign companies to explore and develop the hydrocarbon
prospects. With this objective, GAIL (India) Limited has been awarded a block in Cambay
Basin of India under the Production Sharing Contract (PSC) with the Government of India.
GAIL (India) Limited (GAIL) is integrating all aspects of the Natural Gas value chain
(including Exploration and Production, Processing, Transmission, Distribution and
Marketing) and its related services. With the changing scenario, GAIL is leading light
towards the move to a new era of clean fuel industrialization, creating a quadrilateral of green
energy corridors that connect major consumption centers in India with major gas fields, LNG
terminals and other cross border gas sourcing points. GAIL has been awarded with an
exploration block in Cambay Basin, namely CB-ONN-2010/11 by Government of India
under the Production Sharing Contract (PSC) for exploration of hydrocarbon.
A Production Sharing Contract (PSC) was signed between the Government of India (GoI)
and GAIL, Bharat Petro resources Limited, Engineers India Limited, BF Infrastructure
Limited and Monnet Ispat & Energy Limited on 28th March, 2012. In addition to this,
necessary regulatory approval has been taken for the exploration programme in the form of
Petroleum Exploration License (PEL) from Government of Gujarat on 15th March, 2013.

3.0 Cambay Basin: CB-ONN-2010/11
The Cambay rift Basin, a rich Petroleum Province of India, is a narrow, elongated rift,
extending from Surat in the south to Sanchor in the north. In the north, the basin narrows, but
tectonically continues beyond Sanchor to pass into the Barmer Basin of Rajasthan. On the
southern side, the basin merges with the Bombay Offshore Basin in the Arabian Sea. The
total area of the basin is about 53,500 sq. km.
Thick Cambay Shale has been the main hydrocarbon source rock in the Cambay Basin. In the
northern part of the Ahmedabad-Mehsana Block, coal, which is well developed within the
deltaic sequence in Kalol, Sobhasan and Mehsana fields, is also inferred to be an important
hydrocarbon source rock. The total organic carbon and maturation studies suggest that shales
of the Ankleshwar/Kalol and Tarapur formations also are organically rich, thermally mature
and have generated oil and gas in commercial quantities. Cambay Basin has more than 40
years of active hydrocarbon history.
Out of this total area within the Cambay Basin, GAIL (India) Limited was awarded an
exploratory block of about 131 sq.km through the Production Sharing Contract (PSC).
According to the provisions of Production Sharing Contract (PSC), GAIL has carried out the
whole process of seismic survey and exploratory drilling of seven wells. GAIL is now
planning to carry out development drilling operation of three new wells and recompletion of
existing well Galiyana-1 into production phase for the block CB-ONN-2010/11.
Location of the Block:
The GAIL intends to carry out development/Production of the hydrocarbon potential in
the development area of 59.27 sq. km. Co-Ordinates of the development area are shown
in Table-3.1..

4.0 The Project: Production Operation at Cambay Basin Block CB-ONN-2010/11
On the basis of the interpretation of seismic data for the block CB-ONN-2010/11, GAIL
drilled seven exploratory wells in the first phase (in the depth range of 1500 metres to 2700
metres approximately).
There is one existing discovery well (Galiyana-1) which will be recompleted, as planned
through appropriate work over jobs and it will be converted into development/ production
well.
4.1 PRODUCTION FACILITY (EPS)
EPS facility has been designed considering potential of well for the handling of produced
Fluid/hydrocarbons (Oil, Gas & water) from the wells.
The produced fluid from all the wells will flow to production header and further into
three-phase production separator for gravity separation of oil, water and gas. The
separated oil will then flow into suitable emulsion treating system (E.g. heater
treater/settling tank) for separation of emulsions by combination of heating and chemical
dosing as found suitable. The emulsion treating system will separate gas from incoming
emulsion and break the emulsion into a water phase and an oil phase. Separated oil phase
is then flowed into oil storage tank before being pumped through pipeline (or by tankers)
to dedicated evacuation point while separated water from separator and emulsion treating
system will be flowed through produced water treatment system and followed by disposal
through other GPCB/CPCB approved process, if required.
The Early Production System (EPS) will include the following:
Well Manifold.
Crude heater.
Production Separators (3 Phase Separator).
Flare Assembly.
Electrical Package (transformer, power distribution board, cabling, lighting, earthling etc.).
Settling tank.
Crude oil transfer pump & Storage tank.

4.2 THE WORKOVER RIG
The existing well will be tested and further workover activities will be carried out using a
conventional Workover Rig (Electric) of 200-300 HP, equipped with a Rotory/Top Drive
System. To support the Workover operation, the following systems and services are included
at the rig package:
Portable Living Quarters, provided with Bath/washroom to house essential personnel
on site on a 24 hour basis.
Crane age required for loading/offloading of equipment and supplies
Emergency Systems, which include fire detection and protection equipment
Environmental Protection comprising of Blow out Prevention (BOP) system, waste
water treatment unit, etc.
4.3 RESTORATION AND REHABILITATION
The well is completed when economic quantities of hydrocarbons are found, the well will be
left with a wellhead, Early production System facilities in place. The well site will be fenced
for the production phase and all non-essential area will be fully reclaimed.
After completion of Production Operation Phase, well will be accordingly plugged
and abandoned, and the site will be restored in line with local regulations and good
industry practice. As a minimum, the following steps will be undertaken to restore
and rehabilitate the area
The wellhead and all casing string will be cut off to a minimum depth of 3m (10 feet)
below ground level.
All concrete structures will be broken up and the debris disposed off as per the
regulatory requirements.
All other waste products, solid and liquid, will either be disposed off/will be treated to
render them harmless.
All fencing and access gates will be removed.
