Problems that occur during directional drilling in X-24 wells were evaluated using Compass Software 5000.I. The actual well trajectories deviated from the planned path at some points, including the kick off point, hold section, and total depth. Formation factors and broken downhole survey tools caused the largest deviations. Total loss of drilling fluid from 8546 to 8950 feet required blind drilling and further deviated the well path. This evaluation identifies problems so signs can be recognized earlier to avoid issues and ensure future wells reach planned targets smoothly.

ABSTRACT
Evaluation of directional drilling in X-24 wells is to analyze problems that
occur in these wells. This research aimed to see if there are any problems during
the process of drilling these wells. In this final project, evaluation is done by using
Compass Software 5000.I.
To calculate trajectory comparison between actual and plan, the method
used Minimum Of Curvature. Then compared to calculations between Compass
Software 5000.I with manual calculations. The evaluation also includes data DDR
(Daily Drilling Report), drilling parameters, BHA survey data and used.
The results showed that the actual trajectory of the X - 24 wells deviated
from the plan in some sections is the kick off point, the hold section, and the depth
of the drop section TD. Formation factor in this evaluation and survey tools are
broken is one of the biggest factors that cause deviations occur. In addition the
total loss at a depth of 8546 ft MD up to a depth of 8950 ft MD that led to the
revocation Blind Drilling.
With this evaluation, it is expected that the signs of the problem can be
avoided, before the problem actually occurred on other occasions. So that the
drilling process can run smoothly until a pre-planned targets.
