Offshore drilling is a mechanical process where a wellbore is drilled below the seabed. It is typically carried out in order to explore for and subsequently extract petroleum which lies in rock formations beneath the seabed. Most commonly, the term is used to describe drilling activities on the continental shelf, though the term can also be applied to drilling in lakes, inshore waters and inland seas.
Offshore drilling presents environmental challenges, both from the produced hydrocarbons and the materials used during the drilling operation. Controversies include the ongoing US offshore drilling debate.
There are many different types of facilities from which offshore drilling operations take place. These include bottom founded drilling rigs (jackup barges and swamp barges), combined drilling and production facilities either bottom founded or floating platforms, and deepwater mobile offshore drilling units (MODU) including semi-submersibles and drillships. These are capable of operating in water depths up to 3,000 metres (9,800 ft). In shallower waters the mobile units are anchored to the seabed, however in deeper water (more than 1,500 metres (4,900 ft) the semisubmersibles or drillships are maintained at the required drilling location using dynamic positioning.

Diamond Offshore Drilling Inc. today confirmed that there have been no leaks of hydrocarbons from the semisubmersible drilling rig Ocean Saratoga. The heart-wrenching sight of oil gushing from the seabed and drifting into fragile wetlands along the Gulf Coast has shaken our confidence in deepwater drilling and especially in BP, whose apparent recklessness deserves the stiffest penalties possible.
GE Oil & Gas announces the offshore drilling industry’s first-of-its-kind contractual service agreement (CSA) with Diamond Offshore Drilling, Inc. that transfers full accountability for BOP maintenance and service to GE Oil & Gas. This performance-based model incentivizes BOP availability and will begin to leverage the scale of GE’s data-driven Predix platform for predictive analytics. This 10-year collaborative arrangement for GE’s engageDrilling™ Services showcases a new way of thinking to improve BOP availability and drive continuous improvement in deepwater drilling.

Rig contractor Diamond Offshore Drilling Inc said two of its drillships will be contracted to oil and gas producer Anadarko Petroleum Corp for up to $1.8 billion, the latest in a spate of deepwater deals spurred by higher crude oil prices. The federal government today approved a deep-water drilling blueprint proposed by BHP Billiton, Inc. — the first truly new offshore exploration plan since last year's Gulf spill to survive stepped-up environmental scrutiny.
