Building the Fields
trims cost per well
Through the first quarter of 2016, Chevron had drilled seven exploration wells and nine production wells
in the Jack/St. Malo development.
Daily hydrocarbon production from
the fields reached 75,000 barrels of oil
equivalent per day in March 2016.
Phase 1 development drilling
started in November 2011, resulting in
nine production wells: four at Jack and
five at St. Malo. Development drilling resumed after the production hub
logged its first oil in December 2014.
Phase 2 of the JSM development
Expected production levels
plan includes four additional wells:
two each at Jack and St. Malo. The
front-end engineering and design
(FEED) activities for Stage 2 were com-
pleted in September 2015. The drilling
that began in October 2015 will con-
tinue into 2017. First oil from Stage 2 is
expected in 2017.
The fields have an estimated remaining production life of at least 30
years, with recoverable oil-equivalent resources estimated to exceed
500 million barrels. Beyond that, new
drilling and completion techniques
and advanced production technologies developed in coming years
