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.

GAIL (India) Ltd

Oil Tanker Loading and transportation to nearby facilities

Produced water evaporation pond.

Fire Water System.

Chemical injection skid

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.

GAIL (India) Ltd

All pits whose contents would show regulatory compliance for on-site disposal, at the

time of site closure, will be backfilled and closed out as per the legal requirements.

4.4 STAFFING

In case of production from EPS facility, Being a small facility the average number of people

per shift at EPS will be max up to 6 -10 Nos., who in turn will go back to their residence in

town/ village after the work.

5.0 PROJECT INVESTMENTS

The total cost for installation of Production facilities at exisiting well site would be

approximately 5.3 crores.

GAIL (India) Limited is committed to the prevention of pollution and protection of

environment through a precautionary approach. In line with this objective, GAIL (India) Ltd.

will embark on adherence to best industry practices in its operations and committed to use the

state of art technologies for waste minimization. Careful consideration will be given to

minimize the amount of waste generated and controlling its eventual disposal. All waste

material will be segregated by type; as such garbage will be stored in a designated area and

disposed as per norms. The waste will also be recycled and re-used, if possible. The

environmental management measures will be implemented during the drilling operations and

production phase.
