2.2 Brief Description of Nature of Project

Discovered Small Fields GSKW (Offshore) field earlier drilled by ONGC but have been

awarded to M/s Oil India Ltd by DGH during Discovered small fields 2018 round-II. The

total allocated area of the blocks combined is 93.91sq.km.

2.3 Need for the Project and its Importance to the Country

India’s demand for petroleum products is growing at a rapid rate, having virtually doubled

from 30 million tons in 1980-81 to about 70 million tons in 1995-96 to 201million tons in

2017-18. The oil and gas sector are among the six core industries in India and plays a major

role in influencing decision making for all the other important sections of the economy.

Current projections for demand and supply indicate that the level of self- sufficiency is likely

to decline to about 30% over the next few years. Substantial efforts are, therefore, necessary

to boost the level of exploration activity in the country so that new reservoirs can be

identified to significantly enhance production of crude oil and gas in the years to come. India

today remains one of the least explored regions with oil well density per thousand sq. km

being among the lowest. It is also evident that large amounts of capital investments are

necessary if exploration efforts are to be substantially augmented. It is therefore required to

attract both the national as well as, private sector oil companies to invest in this critical area.

In future exploration for oil and gas in critical areas will be based on social, cultural

environmental, recreational, economic, legal, national and international needs and would

invite development of innovative and supporting technologies for clean operations.

Hence this project of exploratory/development drilling will help in establishing the oil/gas

prospects in the block for commercial recovery, which is a need of the country for its

economic development. It is expected that the proposed development drilling activities lead

to augment the production of hydrocarbons, in the present scenario of growing demand of oil

and gas in the country. The Govt insists to bring down its import dependence on oil and gas

to 67 per cent of its requirement by 2022 thus bringing scope for additional discovery of oil

& gas exploration.

Prime Minister Mr. Narendra Modi insists to bring down its import dependence on oil and

Page 6: Pre-Feasibility Reportenvironmentclearance.nic.in/writereaddata/Online/TOR/08_Nov_2019... · it with local exploration, renewable energy and indigenous ethanol fuel. India was the

gas to 67 per cent of its requirement by 2022 thus bringing scope for additional discovery of

oil & gas exploration.

The proposed project entails drilling eleven wells in the GSKW field to maintain the required

level of hydrocarbon production, (at least 90 MMSCFD) which is lesser than the level of

Permitted hydrocarbon production as per the Environmental Clearance (EC) received from

MoEF&CC, as mentioned earlier.

Due to the replenishment of hydrocarbon production to the earlier levels, long-term

Employment opportunities already generated by the existing project would be sustained.

Besides, the project will help in contributing to the ongoing efforts of the Government to

meet the demand of crude oil and gas from domestic sources and thereby also help in saving

foreign exchange resource. Further the additional benefits from the downstream units such as

power plants also add value to the society.

2.4 Demand Supply Gap

In 1997–98, the New Exploration Licensing Policy (NELP) was envisaged to fill the ever

increasing gap between India’s gas demand and supply. India’s economic growth is closely

related to energy demand; therefore the need for oil and gas is projected to grow more,

thereby making the sector quite conducive for investment.

2.5 Imports vs. Indigenous production

The estimated reserves of natural gas in India as on 31 March 2018 was 1,339.57 billion

cubic meters (BCM), increasing by 3.87% from the previous year. The largest reserves of

natural gas are located in the Eastern Offshore (38.13%) and the Western Offshore (23.33%).

India imports 82% of its oil needs and aims to bring that down to 67% by 2022 by replacing

it with local exploration, renewable energy and indigenous ethanol fuel. India was the third

top net crude oil (including crude oil products) importer of 189 Mt in 2017.

2.6 Export Possibility

The Oil & Gas produced will be utilised for domestic purpose only.

2.7 Domestic/Export Markets

All produced crude oil can be refined in India and sold locally. In case of gas, it would be

fed through the existing pipeline within the state of Andhra Pradesh.

2.8 Employment Generation

Direct Employment during drilling the well at each location will be 50 people and indirect

employment will be 50. During production direct employment will be 25 and indirect

employment will be 50.

presence of commercially proven hydrocarbon reserves is confirmed reserves is to be

established by OIL through 6 Exploratory/development well drilling program as per RSC.

3.4 Size or Magnitude of Operation

The proposed production will be limited to Drilling of 11(Eleven)additional wells and

connect them to the existing unmanned platform or by laying subsea pipeline to connect the

ONGC Gas processing station at Odalarevu for increasing approved production levels in

GSKW field, KG Basin.

3.5 Project Description with Process Details

The proposed mandate will be to drill 11 (Eleven) Exploratory/ development wells either by

fresh wells or by re-entry from few of the existing wells and connect them to the onshore

facilities with subsea pipeline to produce from these wells.

ONGC Odalarevu Onshore terminal is situated close to the block coastline and found to be

suitable for processing of OIL’s Oil & Gas Productions can be taken to their Terminal by

laying Sub-sea pipeline and On-land Pipeline. At present ONGC Terminal is operating at 50

% of the installed capacity and ONGC is having facilities of custody transfer of gas to GAIL

at their Odalarevu Terminal itself which can be used for marketing of the gas.

For Oil marketing, Cairn’s Rava Terminal and Pipeline already laid from Odalarevu Terminal

to Cairn RAVA Terminal can be utilised.

Drilling Activity

Drilling will be carried out by Mobile Offshore Drilling Unit (MODU) – Mat Type Jack up

Rig. It is expected that each well may take around 90 days for drilling, reservoir testing and

suspension under normal condition.

Drilling Plan at GSKW Field

It is anticipated that the well to be drilled in the Block will target depths of ~3700 m

measured depth.

The tentative drilling program is shown below.

The process of drilling activity and the sequence of drilling operations would be as following:

1. To start with, a 30’’ casing called ‘conductor casing’ will be pile driven from the rig into

the seabed to adequate depth to provide a conduit between the rig and seafloor for drilling

operations to proceed.

2. The rotating drill bit, attached on the ‘Drill String’ will be passed through this conductor

casing to the seabed.

3. The initial part of the well or top hole will be drilled and then cemented with metal casing,

The drilling will be continued with a smaller bit to create a hole of smaller diameter, which

will then be cased and cemented with metal casing. The operation will be continued in this

way till the reservoir is reached.

In the development well, typically a 26’’ hole will be drilled followed by 20”casing, then a

17.5” hole will be drilled followed by 135/8’’ casing, then 121/4’’ hole will be drilled

followed by a 95/8’’casing and finally a 81/2’’ hole will be drilled into the reservoir followed

by a 71/2’’ casing.

3.8.1 Power Requirement

The drilling process requires movement of the drill bit and string through the draw works

which require power. The power requirement of the drilling rig (~3750 KW) will be met by

using the Diesel Generator (DG) sets on-board. High Speed Diesel (HSD) will be used to run

drilling rig and DG sets during operation. Consumption of HSD is expected to be ~6-9 KLD.

3.9 Quantity of Wastes to be Generated (Liquid and Solid) and Scheme for their Management

Disposal.

Solid Waste Management

The drilling rig system to be employed for drilling will be equipped for the separation of drill

cuttings and solids materials from the drilling fluid. The drill cuttings cut by the drill bit, will

be removed from the fluid by the shale shakers (vibrating screens) and centrifuges and

transferred to the cuttings containment area. Once the drilling fluid / mud have been cleaned,

it will be returned to the fluid tank and pumped down the drill string again.

Types of Solid Waste

Various solid wastes generated during the drilling campaign would include drill cuttings,

Cardboard, papers, scrap metal, wood and packaging material, oil and oil contaminated

wastes, contaminated containers and packaging materials, plastic and other wastes.

Quantity of Waste

The quantity of waste generated would be as per Table 9.

Method of Handling and Disposal

The general method of handling and disposal of solid wastes will be as follows:

• Drill cuttings will be separated from the mud and shale shaker using a fine mesh and

washed. Washed drill cuttings will be discharged at the well location as per stipulated norms.

• General wastes, scrap metal and wood will be segregated and brought back to the shore for

appropriate disposal.

• All plastic / paper waste will be collected and brought back to the shore for disposal to scrap

dealers.

• Waste lubricants and hydraulic oils generated from the equipment on board will be brought

back to the shore in a drum and disposed off to authorized waste recyclers.

• Containers of oil and other materials will be brought back and sold to APPCB /CPCB

authorized recyclers.

Liquid Waste Management

Sewage

The drilling rigs / vessels will be fitted with on board sewage treatment plants to meet the

discharge effluent quality to MARPOL (Annex IV: Regulations for the Prevention of

Pollution by Sewage from Ships) convention requirements.

Effluent

The drilling mud will be recycled and maintained in good condition throughout the operation

to restrict the wastages. The non-hazardous, spent drilling mud (WBM) will be discharged

into the sea as per norms. The toxicity of 96 hours LC50 (>30,000 mg/litre) will be ensured

during the disposal of the unusable portion of the mud. The offshore discharge will be carried

out intermittently at an average rate of 50 bbl / hour, to ensure proper dilution and dispersion

without any adverse impact on the marine environment

The synthetic base drilling mud will be recycled and re-used to the maximum extent possible,

for future drilling. The SBM used will comply with the toxicity limits prescribed by MoEF.

At the end of the drilling campaign, SBM will be brought to the shore for disposal to an

authorized TSDF.
