Onshore drilling is land drilling: wells typically take
days to drill -- maybe 30 days, maybe 45 days, depending on
desired depth, and rigs are contracted in days, as opposed
to months and years for offshore drilling.
Offshore drilling can be deepwater (technically defined as
water deeper than 650 feet, or 200 meters) or shallow water
(water as shallow as 20 feet or as deep as 200 feet).
Drilling offshore in deepwater takes the most
technologically advanced rigs and experienced workers.
Dayrates for offshore rigs start in the midteens and can
run over $200,000 per day, depending on the rig and the
location of the drilling project.
Offshore refers to a foreign locale that is far away in
distance and, more importantly, far apart in time from your
Nearshore also refers to a foreign locale but one thatís
much closer to you.
Onshore is a locale in the same country as yours.
