Continuous Inclination Measurements and BHA Modeling Help Detect Microdoglegs

Microdoglegs are a natural effect of any vertical or directional well that can explain a wide variety of downhole problems.

Microdoglegs are a natural effect of any vertical or directional well that can explain a wide variety of downhole problems. A trajectory-prediction model able to calculate the inclination and azimuth approximately every 12 in. has been developed to estimate microdoglegs using standard surveys, bottomhole-assembly (BHA) data, and steering parameters. This new methodology combining downhole data measurements with drillstring-modeling analysis highlights the potential for drilling optimization and wellbore placement.
