Offshore deep water oil drilling

Abstract

The difference between offshore deep water drilling of oil wells and shallow water drilling lies in the indicator of the depth at which the work is carried out. The process of extraction of minerals (oil) occurs with the help of mobile platforms and installed equipment. The concept of deep-sea drilling is defined for works that are carried out at a depth of more than 600 meters. Offshore deep water drilling is carried out with the help of equipped drilling vessels with the property of dynamic stability. Greater depth is marked by the probability of a slight deviation of the drill from the initial position. With this type of oil production, a deviation of the well radius in the amount of three percent of the sea depth is allowed. Crosswinds or frontal winds up to forty-five knots are allowed.
