Prospect Evaluation
Successful exploration requires
integration of multiple diverse
data types from wells, seismic
and other geophysical surveys to
predict where viable traps have
been charged with oil and gas.
The image above shows predic-
tions of oil (green) and gas (red)
in undrilled traps. The Petrel
platform provides an integrated
environment where exploration
teams can develop a shared
understanding of uncertainty
and subsurface risks associated
with these prospects. New capa-
bilities (left) enable assessment of
the chance of success and
ranges of potential resources in
place linked to undrilled prospect
data and interpretations.
