Natural Gas STAR Partnership
U.S. Natural Gas STAR Partner – 1994
International Gas STAR Partner – 2006
MOC was a charter member of both the U.S.
and International Natural Gas STAR
programs.
Awarded Production Partner of the Year –
1997 and 2006
Cumulative methane reductions of 51.6 Bcf
between 1994 and 2007

Methane Reduction Projects
Two categories of projects – all relate to
reductions in flaring of natural gas
– Process Control Modifications
– Equipment Modifications/Installation

Process Control Modifications
Reviewed emergency shutdown (ESD) settings –
too high/low
Eliminated single-point failure controls (where
possible) – reduces affect of “false” data in
controls
Reviewed interconnected controls – allows for
quicker/automatic load transitions between
redundant equipment
11
Equipment Modification/Installation
Installed redundant equipment – increases
capacity to allow for maintenance without product
loss
Re-routed vapors away from the flare and back
into the process where feasible
Installed pump to improve water handling
capabilities
Overhead compressors re-routed scrubber liquid
to a closed drain system (from pressure process
vessel)
12
Methane Reduction - Economics
Natural gas is low value commodity for
MEGPL under it’s present supply
contracts
Project economics are typically driven
by lost production or value of liquid
recoveries from the gas
13
Lessons Learned:
Improve the quality of data used for emission
calculations – lack of meters, documentation,
etc. You need to know where your losses are!
Capture “low hanging fruit” – review ESD set
points, control logic, etc
Operations and maintenance need to be
engaged – not just an environmental issue.
Moving from construction to operation
mentality takes time and effort.
14
MEGPL – Government Interaction
Limited environmental regulations – don’t
address air emissions/greenhouse gases
Proactive – prepare a “Flaring
Philosophy” document each year for
review with the Ministry of Mines, Industry
and Energy (MMIE)
15
MEGPL - Social Responsibility
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
Education Scholarships – Texas A&M
and University of South Carolina
Malabo Landfill – Construction of
landfill used for waste generated on
island. Operation of landfill by Malabo
City Hall
Books for Bioko – employee driven
program to provide school supplies for
local schools
