Abstract: Discovery History of the Giant Cusiana and
Cupiagua Oil Fields, Colombia
By
Senior Vice-President of Exploration, Triton Energy Corporation
"In geology, the present is the key to the past - but the discovery history of the Cusiana Field is the key to future exploration."
The Cusiana Field in Colombia is
the largest discovery in the Western
Hemisphere in the past 20 years and the
largest in the 80-year history of the Colombian
oil industry. The area attracted
exploration attention in the 60s and 70s,
and the Cusiana and Cupiagua accumulations
were actually penetrated - so
why were they not discovered? When
Triton acquired the acreage in 1982,
potential farminees were not attracted
by the Cusiana feature and two farmin
wells were drilled on different play
types
in the license. In the late 80s, on
two separate occasions, over 120 companies
declined the opportunity to drill
a Cusiana farmin
well
. On the second
occasion, this occurred even after the
Cusiana 1 discovery
well
had been
drilled by BP, Total, and Triton.
The critical technological and commercial factors influencing the discovery history will be presented, as will perceptions on the political and economic climate and exploration prospectivity.
A summary of the petroleum geology will be described and development activities will be brought up to date.
