Drilling platforms

The Sea platform 

The production facilities sit atop a large submersible hull on atower. When the lower hull fills with water, it sinks to a lower depth, providing stability while keeping the facilities high and dry. However, instead of giant anchors holding it in place, the Sea Star is connected to the ocean floor by tension legs. These long, hollow tubes remain rigid at all times, preventing any up-and-down motion on the platform. The legs are just flexible enough to allow side-to-side motion, which helps absorb the stress of waves and wind. These platforms operate from depths of 500 to 3,500 feet (152 to 1,067 meters) and are typically used to tap smaller reservoirs in deep waters

The most important feature is that it operates on natural gas. “That means there no risk of an oil spill. That’s what most people are concerned about, an oil spill in a marine environment,” Webb said. “Second, there’s no offshore processing equipment. The noise it generates is a lot less. Because it only has one piling caisson leg, one pipe that goes into the water, the footprint is a lot smaller

Onshore , Offshore Oil , Gas Production

Onshore and offshore oil and gas production can take organizations to remote locations all around the world

From the middle of the ocean to rugged landscapes inland, the need to connect these locations reliably and securely is critical

Sidetracking is one of the primary uses for directional drilling. Sidetracking is an operation which deflects the borehole by starting a new hole at any point above the bottom of the old hole as in Figure below

The primary reason for sidetracking is to bypass a fish which has been lost in the hole; however, there are several other reasons for sidetracking. A sidetrack can be performed so the bottom of the hole can intersect a producing formation at a more favorable position such as up dip above the oil-water contact. A well can be sidetracked to alleviate problems associated with water or gas coning. A sidetrack can be performed in an old well to move the location of the bottom of the hole from a depleted portion of the reservoir to a portion that is productive, such as, across a fault or permeability barrier

Most often, a sidetrack is accomplished by setting a cement plug in the hole and dressing off the plug to a depth at which the sidetrack will commence. The sidetrack can be either "blind" or "oriented". In a blind sidetrack, the direction of the sidetrack is not specified and is not considered a directional well. In either case, a deflecting tool is used to drill out the old hole and start a new hole

Petroleum history

Petroleum history

It was drilled the first oil well in China in the fourth century AD, and the modern history of oil began in Poland in 1853 discovered crude oil distillation processes, and in the US oil industry began to discover Edwin Drake (Edwin Drake's) of oil in 1859 near Pennsylvania

Petroleum components

Petroleum consists of a mixture of a number of hydrocarbons that are different in nature and in their properties. And can not use his state of crude petroleum which is extracted from the ground, but the various components must be separated and purified for the use of each of them in purpose, this process is known as the process of refining. It can not be separated from each hydrocarbon crude oil components separately; because the boiling points of these hydrocarbons are close to a large extent
