The document summarizes Marathon Equatorial Guinea Production Limited's (MEGPL) operations in the Alba Field located offshore of Equatorial Guinea. It details the four offshore production platforms and onshore processing facilities that currently produce 945 million standard cubic feet per day of natural gas and 60,000 barrels per day of condensate. It also provides a brief history of the field and details MEGPL's partnership with the Natural Gas STAR program, outlining methane reduction projects implemented and lessons learned.

Natural Gas STAR Partnership
Š U.S. Natural Gas STAR Partner – 1994

Š International Gas STAR Partner – 2006

Š MOC was a charter member of both the U.S.


and International Natural Gas STAR
programs.

Š Awarded Production Partner of the Year –


1997 and 2006

Š Cumulative methane reductions of 51.6 Bcf


between 1994 and 2007

Methane Reduction Projects

Š Two categories of projects – all relate to


reductions in flaring of natural gas
– Process Control Modifications
– Equipment Modifications/Installation

Process Control Modifications

Š Reviewed emergency shutdown (ESD) settings –


too high/low

Š Eliminated single-point failure controls (where


possible) – reduces affect of “false” data in
controls

Š Reviewed interconnected controls – allows for


quicker/automatic load transitions between
redundant equipment

11
Equipment Modification/Installation

Š Installed redundant equipment – increases


capacity to allow for maintenance without product
loss

Š Re-routed vapors away from the flare and back


into the process where feasible

Š Installed pump to improve water handling


capabilities

Š Overhead compressors re-routed scrubber liquid


to a closed drain system (from pressure process
vessel)

12
Methane Reduction - Economics

Š Natural gas is low value commodity for


MEGPL under it’s present supply
contracts

Š Project economics are typically driven


by lost production or value of liquid
recoveries from the gas

13
Lessons Learned:
Š Improve the quality of data used for emission
calculations – lack of meters, documentation,
etc. You need to know where your losses are!

Š Capture “low hanging fruit” – review ESD set


points, control logic, etc

Š Operations and maintenance need to be


engaged – not just an environmental issue.

Š Moving from construction to operation


mentality takes time and effort.

14
MEGPL – Government Interaction

Š Limited environmental regulations – don’t


address air emissions/greenhouse gases

Š Proactive – prepare a “Flaring


Philosophy” document each year for
review with the Ministry of Mines, Industry
and Energy (MMIE)

15
MEGPL - Social Responsibility
Š Malaria Control Project – public/private
partnership to reduce malaria rate.
– Eliminated 95% of disease transmitting
mosquitoes and reduced infection
rates by 45% reduction in malaria

Š Education Scholarships – Texas A&M


and University of South Carolina

Š Malabo Landfill – Construction of


landfill used for waste generated on
island. Operation of landfill by Malabo
City Hall

Š Books for Bioko – employee driven


program to provide school supplies for
local schools
