INTRODUCTION
MARGINAL FIELD – Definition
Marginal Field, a field that may not produce enough net income to make
it worth developing at a given time; should technical or economic
conditions change, such a field may become commercial. i.e, Subeconomic at current cost
A field may be categorized as marginal under following considerations:
 Reservoir size (small volume)
 Lack of infrastructure / technology
 Inaccessibility to the area- remoteness
 Fiscal policy
 Market for gas
 Cost of development

An approach paper was put up at 84th Board meeting, in Nov 2001
2nd strategy meet at Sariska in February 2002 deliberated marginal
fields development
3rd strategic meet in July 2002 – following strategic options were
discussed
 In-house development
 Alliance with profit sharing with other E&P companies
 Through service contract
230th meeting held on 17th September 2002, EC decided that the
fields be offered to the private companies in phases
In the Project and Planning committee meeting held on 22nd
October 2002 at New Delhi, it was decided to first offer 19
onshore marginal fields

Background

In the first QPR of ONGC held on 09.08.2007 with DGH for development
of Marginal fields, DGH was asked to suggest a mechanism to ONGC for
outsourcing of marginal fields through bidding process in a more lucrative
way.
In the 6th Business Strategy meet of ONGC held at Agra on 25-26 August
2007 the Ministry desired that marginal fields to be identified by both
ONGC and DGH and based on comprehensive analyses a suitable business
model could be developed for optimum usage.
DGH visited Mumbai from 5-7th September 2008 and data of 18 fields were
examined
DGH presented the brief strategy for development of Marginal Fields to
Additional Secretary, MoP&NG on 20th September 2007 wherein it was
decided that a draft Marginal Field Policy (MFP) covering all aspects of
Marginal Fields of NOCs be proposed.
During 3-5th October DGH team again visited Mumbai and data of another
81 fields were examined jointly.

Background (Contd.)

DGH / ONGC made presentations on 18.10.2007 and 11.12.2007 in meetings chaired
by Additional Secretary, MoP&NG and it was desired that MFP may be evolved with the
following salient features

Production Sharing contract

Freedom to market/ utilize gas
International Crude Price
Gas Price at arm’s length
Royalty- To be borne by contractor or ONGC
Cess – Whether to be exempted
Exemption of Customs Duty- modalities and relative merit






On the basis of deliberations in the meeting held on 21st February, 2008 a draft
Marginal Field Policy was prepared by the committee

The MFP was deliberated in the meeting held on 08.05.2008, chaired by Additional
Secretary, MoP&NG. It was decided that:


Adopt single rate of production sharing

With effect from 01.05.2008 if production does not commence within 5 years for onshore
blocks and 7 years for offshore blocks, they would be considered for offer under MFP
No recovery of past cost incurred by NOCs.

In the meeting dated 22.01.2009 chaired by Joint Secretary, MoP&NG, a
committee was formed to prepare a model contract by 15.02.2009 after
which new policy would be put up for approval.
Draft Model Contract was prepared and submitted to MoP&NG
Initially 22 Marginal Fields were identified with the option of offering other
marginal fields as and when they are available. Subsequently it was decided to
develop two fields in-house, while another six fields are included making the
number 26 fields
In response to a letter of ONGCs, Ministry informed on 10th October 2010
that the proposal for development of marginal fields through service
contract with a more realistic cap on crude prices and also the proposal to
increase the cap on crude prices for existing contracts need to be examined
by the Board of ONGC in the context of the existing guidelines/framework
Board has approved outsourcing of marginal fields with improvements/
changes of the existing service contracts in the 224th meeting held on 4th
November 2011
