The aim of this study is to develop a program compare directional survey models and select the most accurate. When drilling well, actual route well must be regularly checked ensure that it in agreement with planned route. This done by measuring position at constant intervals. A was established used for five methods (Minimum Curvature, Tangential, Angle Averaging, Balanced Radius Curvature) path...

The oil industry uses geomagnetic field information to aid directional drilling operations when drilling for oil and gas offshore. These operations involve continuous monitoring of the azimuth and inclination of the well path to ensure the target is reached and, for safety reasons, to avoid collisions with existing wells. Although the most accurate method of achieving this is through a gyroscop...

Inadequate hole cleaning can lead to many problems in horizontal and directional wells. In this work, we tried to investigate the cutting transport phenomenon by an experimental directional drilling simulator, considering the differences between the operational and experimental conditions. The inclination, fluid type (water, foam, viscous, and dense), rotary speed (0 and 110 rpm), nozzle bit si...

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...
