| Summary: | The drilling rate and the trajectory of the wells under study will be evaluated based on the lithological information, regional efforts and stability on the face of the well to adapt the trajectories to the regional lithology, thus taking advantage of the characteristics in respect thereof to improve the drivability and increase the penetration rate.
This article exposes the challenge of aligning all the geological variables and arranging them in a way that optimizes drilling, as there is a specific interest within the reservoir developed and proposed by reservoir engineers, which sometimes prevents taking advantage of the orientation of the main efforts on the face of the well, as well as the regional efforts of the perforated area. When establishing a relationship between lithology, geomechanical characteristics, drilling problems and the penetration rate of the wells analyzed, parameters were determined that allowed each section of the well to increase the drilling rate in response to a better adaptation of the geology.
The paper includes suggestions of the possible directions that a well could take based on polar stability diagrams, which, together with a trajectory perpendicular to regional efforts, would lead to an increase in the penetration rate.
