   Dogleg severity is a measure of the amount of change in the inclination, and/or azimuth of a borehole, usually expressed in degrees per 100 feet of course length. In the metric system, it is usually expressed in degrees per 30 meters or degrees per 10 meters of course length.

   How do you calculate dogleg severity?

   • DLS = (1) cos −1 (0.9982) DLS = 3.42° / 100 ‘ The dogleg severity for the remaining constant inclinations was calculated and is shown in Table 2. At an inclination of 1°, the dogleg severity is 0.17°/100 feet for a 10° change in azimuth. At an inclination of 50°, the dogleg severity is 7.66°/100 feet for the same change in azimuth.

   What is dogleg severity?

   • It should be remembered that the dogleg severity is a measure of the curvature between survey points. This may not be a true indication of the actual dogleg severity. As an example, assume a drilling whipstock was used to change the inclination of a well. Calculations from a 100 foot survey interval indicated a dogleg severity of 3°/100 feet.

   How do you calculate dogleg angle?

   • The DLS is then obtained by dividing the change in angle by the course length between the stations and then multiplying by 100. To derive the formula to calculate the dogleg angle, consider the survey stations shown in Fig. 3.75. At the upper station, the inclination and azimuth have been measured as αA and β A.
