Abstract

The spatial position of a deviated borehole is determined from measurement data. At a number of points Mᵢ (i = 1, 2, …, n) taken along the borehole length, measurements provide values of inclination angles θᵢ and azimuth φᵢ. From these data and the distances sᵢ of points Mᵢ from the wellhead, the position of points Mᵢ and of the entire borehole is determined. This determination can be made by various methods, each of which yields an approximate borehole position. The question arises of evaluating the possible deviation of the obtained borehole position from the actual one, and of how the accuracy of determining the borehole's spatial position depends on the accuracy of the angle measurements and on the number of points at which such measurements are made.
