Abstract

The Brazilian oil industry is characterized by the large offshore exploratory efforts, since the country's largest reservoirs are at sea. It is increasingly common in Brazil, the use and development of costly technolog y for drilling in deepwater and ultra-deep, which requires large investments in dri lling step, reaching the order of tens of millions of dollars. With the growing number of offshore structures operating in the area, the need to develop and modernize systems tha t allow oil exploration in deep water more efficiently and safely, has represented major investment in dynamic positioning systems (DP – Dynamic Positioning ). Dynamic positioning is a system that automatically controls the position and aproamento of a vessel propelled by active, ( BRAY, 1998; FOSSEN, 1994 ). The propulsion systems used must have special requirements that may differentiate them from prope llants commonly used in navigation. This article discusses the importance o f the reference systems used in drilling rigs for oil wells, Its main features and detail that makes them essential for maintaining the desired position, bow desired direc tion and speed of the probe during the drilling operation of oil wells.
