Continuous Wellbore Surveying While Drilling Utilizing MEMS Gyroscopes Based on Kalman Filtering

Abstract: The current method to compute the wellbore while drilling is based on stationary surveys at the desired station. This is done by measuring the inclination and the azimuth of the borehole between the current and the previously surveyed stations. Using a mathematical model based on assumptions of the shape of the drilled section, the coordinates of the borehole can be derived. This current method neglects the actual trajectory between the two surveying stations.Exploration and production companies demand cost ef… Show more

“…Also, MEMS gyroscopes are subjected to various shock impacts [22]. Typical MWD tools currently used in industry favor accelerometers [23], but gyroscopes are often found in tools used for continuous drilling survey applications [24]. Non-strapdown based gyroscopes that may be more robust to the downhole environment are available (for example fiber-optic coils); however, current technologies are not economically viable [25].…”

“…In practice, there are three different ways to obtain Toolface. The first one is based on the tri-axial accelerometer [ 5 , 6 ], but in the drilling process, besides the kinematic motion acceleration, the drilling shock can be over 200 g [ 7 ] and the vibration acceleration is over 5 g [ 8 , 9 ]. Therefore, this method cannot provide an accurate Toolface estimation [ 5 ].…”

“…Higgins points out that CF is actually a steady-state KF. KF-based techniques have been studied in the areas of downhole inclination and azimuth estimation [ 6 , 15 , 16 ], but most of those methods are complex and impose high computational demand.…”

“…Usually, a horizontal borehole trajectory is complicated and measurement-while-drilling (MWD) equipment is needed for directional drilling [2]. In recent years, inertial navigation systems (INS)-based MWD equipment, free from magnetic interference, has been developed and studied [3][4][5][6] as an alternative to the magnetometer-based MWD surveying system. The INS-based MWD equipment employs an inertial measurement unit (IMU), which consists of a gyroscope triad and a linear accelerometer triad.…”
