1. A method comprising:
- defining drilling data for drilling a segment of a planned wellbore;
identifying a risk zone in the segment;
determining an expected fluid loss volume for the risk zone; and
selecting a solution to reduce fluid loss in the risk zone; and
drilling the planned wellbore with a drill bit using the selected solution.

Abstract
A method for planning a wellbore, the method including defining drilling data for drilling a segment of a planned wellbore and identifying a risk zone in the segment. Additionally, the method including determining an expected fluid loss for the risk zone and selecting a solution to reduce fluid loss in the risk zone. Furthermore, a method for treating drilling fluid loss at a drilling location, the method including calculating a drilling fluid loss rate at the drilling location, classifying the drilling fluid loss based on the drilling fluid loss rate, and selecting a solution based at least in part on the classifying.
