ExxonMobil is conducting field trials of eight emerging methane
detection technologies, including satellite and aerial surveillance
monitoring, at nearly 1,000 sites in Texas and New Mexico to
further reduce methane emissions.
The field tests are evaluating effectiveness and scalability of
a range of next-generation detection technologies that in addition
to satellites use drones, planes, helicopters, ground-based mobile
and fixed-position sensors. All technologies and deployment methods
will be used to detect leaks and identify potential solutions that
can be shared with other oil and gas operators.
“By testing the most promising methane detection technologies in
a field environment, we are providing viable solutions that can be
adopted by other producers to detect and reduce methane emissions,”
said Staale Gjervik, senior vice president of unconventional at
ExxonMobil. “We are applying scientific rigor and taking aggressive
steps to find commercially scalable and affordable solutions for
all operators.”
The technologies are being validated by a combination of field
observations, optical gas imaging cameras and portable methane
detection instruments. ExxonMobil is also comparing measurements to
downwind emissions observations using technology by Aerodyne
Research that enables holistic measurement of site emissions.
“We are already seeing the benefits of some of these
technologies,” said Gjervik. “Through the trials, we have
discovered methane sources that would otherwise not have been
detected as efficiently or quickly under the current methods
prescribed by regulations. The company is committed to immediately
investigating and fixing methane emissions that are detected during
the trial.”
The field trials build upon ExxonMobil’s previously announced
emission reduction initiatives. As of year-end 2019, the company
has reduced emissions by nearly 20 percent in its U.S.
unconventional operations compared to 2016 levels, and the company
remains on track to meet its corporate-wide commitments to reduce
methane emissions by 15 percent and reduce flaring by 25 percent by
year-end 2020. ExxonMobil’s successful voluntary methane management
program includes structured leak detection and repair protocols,
prioritized replacement of high-bleed pneumatic devices, technology
enhancements to infrastructure and substantial data gathering and
research.
In March, ExxonMobil introduced a model framework for
industry-wide methane regulations and urged stakeholders,
policymakers and governments to develop comprehensive, enhanced
rules to reduce emissions in all phases of production.
The company supports the Methane Guiding Principles, which were
signed in 2017 and are being implemented in collaboration with
multinational stakeholders.
Since 2000, ExxonMobil has invested nearly $10 billion in
projects to research, develop and deploy lower-emission energy
solutions. The company also continues to expand collaborative
efforts with more than 80 universities around the world to explore
next-generation energy technologies.
Following are technologies and technology providers involved
in the testing.
Aerial Surveillance Bridger Photonics - Aerial light
detection and ranging sensor (LiDAR) to pinpoint and measure
leaks.
Scientific Aviation – Airplanes equipped with sensors, coupled
with weather and atmospheric information to measure methane
emissions.
Kairos Aerospace – Airplane-mounted methane detection
spectrometer with simultaneous optical imagery and geolocation to
quickly locate large leaks.
Leak Surveys Inc. – Helicopter-mounted, gas imaging surveys.
SeekOps – Drone-mounted gas sensors to detect and quantify
methane emission rates.
Satellite Surveillance GHGSat – Satellite measures
methane concentrations, to detect leaks and estimate emission
rates.
Truck Mounted Monitor mAIRsure – Truck-mounted autonomous
sensors measure methane emissions.
Fixed-Position Monitor Troposphere - Stationary methane
and wind sensors continuously monitor for emissions.
