As the company waits for environmental
authorisation for the Uaru project, ExxonMobil
is working to limit the possibility of gas flaring
issues at the field. Anthony Jackson, ExxonMo-
bil’s in-country projects manager, has stated that
the company will look to install spares for the
vessel’s compression system in order to reduce
non-routine flaring. Going forward, ExxonMo-
bil is looking to develop a “flare minimisation
plan”, he was quoted as saying by OilNOW.gy.
The US-based super-major repeatedly
experienced flaring problems at Liza-1, its first
production target, in 2020 and 2021, due to tech-
nical issues with the flash gas compressor (FGC)
system on the FPSO installed at the field. Those
issues have been resolved, and ExxonMobil says
it has applied the lessons learned at Liza-1 to its
other development projects at Stabroek.
Equity in the Stabroek project is split between
ExxonMobil, the operator, with 45%; Hess, with
30%; and state-run China National Offshore
Oil Corp. (CNOOC), with 25%. The deepwater
block covers an area of 26,800 square km and
contains at least 11bn barrels of oil equivalent
(boe) in recoverable reserves.
The US giant and its partners have already
made more than 25 commercial discoveries
at Stabroek since they first struck oil at Liza in
2015. They launched production at Liza-1, their
first development target, in December 2019 and
then brought Liza-2, the second development Uaru and Mako lie to the east of the Liza oilfield (Image: Hess)
