Also, the distance between surveys has an effect on the quantity of the error.If survey intervals were 10 feet or less, the error would be acceptable.In some deviated wells, the error in TVD was more than 40-50 feet."This technique provides a smoother curve which should more closely approximate the actual wellbore between surveys.The longer the distance between survey stations, the greater the possibility of error.When using the average angle method, the inclination and azimuth at the lower and upper survey stations are mathematically averaged, and then the wellbore course is assumed to be tangential to the average inclination and azimuth.Since the average angle method is both fairly accurate and easy to calculate, it is the method that can be used in the field if a programmable calculator or computer is not available.
