To decide on a site with a potential oil/gas payout, Geologists and Geo-Scientists work their ways in and around the information collected off the areas with possible oil or gas reservoirs. Survey vessels with or without Dynamic Positioning systemsare hired for seismic surveys. These maritime vessels are equipped. . Once the site is identified and selected, boundaries are surveyed and earmarked by the local governing body for Energy and Resources. Studies for impact on the environment are carried out. After determining the potential energy sites, oil companies are then. . After the potential energy-rich blocks are legally cleared, oil companies pursue their investments by employing mobile drilling units that are temporarily acquired and are able to move on to. . These self-contained drilling structures are as good as the drilling barges only to the exception that these massive structures are positioned onto. . They are mostly utilized for shallow water drilling in calm water conditions. Drilling equipment is placed on to the barges’ decks and towed to. [pdf]

As of June 2010, there were over 620 mobile offshore drilling rigs (jackups, semisubs, drillships, barges, etc.) available for service in the worldwide offshore rig fleet. . Offshore drilling is a mechanical process where a is drilled below the seabed. It is typically carried out in order to explore for and subsequently extract that lies in rock formations beneath the. . Offshore drilling is usually done from platforms generically known as mobile offshore drilling units (MODU), which can be of one of several. . Offshore oil and gas production is more challenging than land-based installations due to the remote and harsher environment. Much of the innovation in the offshore petroleum. . Offshore oil production involves environmental risks, most notably from oil tankers or pipelines transporting oil from the platform to onshore facilities, and from leaks and accidents on the platform (e.g. and . Around 1891, the first submerged oil wells were drilled from platforms built on piles in the fresh waters of the in . The wells were developed by small local. . Notable offshore fields include:• the • the (offshore , , , and )• (in the and , part of the Ventura Basin) . • • • • • • [pdf]
