This paper proposes the use of a hybrid approach to perform the trajectory control in the oil drilling industry using Rotary Steerable Systems (RSS). Two levels of automation are proposed, the attitude control (Level 1) regulating inclination and azimuth downhole and the outer loop (Level 2), that monitors the performance of the inner loop and controls the directional drilling commands issued t...

Abstract Magnetic debris in a drilling fluid have significant influence on the ability of to maintain its function. Down hole logging can suffer from poor signal noise ratios. Directional areas close magnetic North Pole, such as Barents Sea, Northern Canada, or Russia, because contamination fluid. particles introduce additional errors surveying compared those normally included ellipsoid uncerta...

Gyroscopic survey technology is one of the key technologies to promote progress directional drilling technology. It great practical significance study error well trajectory measurement based on gyro surveys and identify main sources. This paper introduces sources which lead uncertainty borehole position in gyroscopic survey, six models, calculation model contribution rate ellipse. The differenc...

Russia's four largest petroleum companies, Rosneft, Surgutneftegaz, Gazprom Neft, and Lukoil, account for more than 50% of production 70% the demand in drilling market. All these companies are profoundly relaying on Foreign Direct Investments (FDI) import equipment technologies. FDI have been mostly received from European Union (EU) countries United States (U.S.) also major providers technologi...
