Brunei Shell Petroleum and designed by a local
architect, the Billionth Barrel Monument
commemorates the production of the billionth
barrel of oil by the Seria oilfield. It is
located close to the seawell, near the site
'S-1', the first well dug almost 70 years ago.
The approach to the
monument is through an arched entrance and a row
of trees on either side. The arches serve to
remind visitors that Brunei is an Islamic
country and the floor is tiled in an Islamic
pattern. The monument is a mere 5-minute drive
from the Seria town centre.
