Flaring down in nigeria l.jpg

Flaring Down in Nigeria

View of Nigerian flares as seen from the satellite

An unusual brightness in the dark of the African continent

Nigeria produces 2.3 M Bopd of oil and 6 BScf/day of associated gas.

About 45% of produced gas is presently flared.

Gas reserves in the country are estimated to be 180 Tcf

The government through fiscal incentives has opened new markets

The exportation of liquefied natural gas (N-LNG) started in 1999


History of eni in nigeria 1 l.jpg

History of Eni in Nigeria (1)

  • 1962 Establishment of “Nigerian Agip Oil Company” NAOC starts exploration activities

Agenda

  • Background: Flaring down in Nigeria

  • The Kwale - Okpai Project overview


The project concept l.jpg

The Project Concept

PURPOSE/ACTIVITY

Utilization of previously flared associated gas produced in the Kwale Oil-Gas Processing plant

  • Transportation of the gas through a 14 km long pipeline

  • Use as fuel in plant and in ad hoc built Combined Cycle Gas Turbine Independent Power Plant

Project description l.jpg

Project Description

  • IPP PROJECT PARTNERS

    • NNPC (60%); NAOC (20%); PONL (20%)

  • TECHNOLOGY

    • Gas dehydration, taking up ullage at the existing Kwale OGPP;

    • Gas compression

    • 14 km pipeline inter-connector from the Kwale OGPP to the IPP at Okpai

    • A 480 MW combined cycle gas turbine power plant


Methodology overview l.jpg

Methodology Overview

Approved Methodology AM0009 version 02

Recovery and utilization of gas from oil wells that would otherwise be flared


Baseline and monitoring plan l.jpg

Baseline and Monitoring Plan

BASELINE

CO2 equivalent emissions from flaring of associated gas, less:

  • Volume of dry gas exported from Kwale plant to OB/OB gas plant

  • Volume of dry gas used for reinjection at OML 60

    MONITORING

    Ex post monitoring of various carbon flows across the gas recovery, processing, export, and emergency relief (flares) systems, plus any accidental releases through plant or pipeline failure


Boundaries and crediting period l.jpg

Boundaries and Crediting Period

BOUNDARIES

The project boundaries are the Kwale Oil-Gas Processing Plant and the pipeline inter-connector between Kwale OGPP and the IPP

CREDITING PERIOD

A crediting period of 10 years (2006-2015) has been chosen

OVERALL CREDITS

14.97 Miln tones CO2eq

Conclusions l.jpg

Conclusions

The Clean Development Mechanism

A help for the Oil &Gas sector in the economic efforts to:

  • Cut flaring and venting emission

  • Deploy Efficient Technologies in developing countries

    The Kwale – Okpai Project

    A contribution to sustainable development. Its benefits:

  • A significant step to Eni "Zero Gas Flaring" Plan

  • Climate change mitigation

  • Deployment of sustainable technology in Nigeria

  • Boosting CDM projects development in Nigeria

  • New opportunities to implement flaring down projects worldwide
