| English term or phrase: onshore/offshore | onshore/offshore
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. |
