Abstract
The SR-11 well encountered obstacles to drilling operations in section 12 ¼”
caused by poor or smooth borehole geometry due to the formation of ledges on the
surface of the borehole wall that can hinder drilling operations such as tripping
and casing installation activities. Therefore, there is a considerable increase in the
cost of drilling operations from the planned cost.
The completion method used in this study is to evaluate the drilling results through
reading the drilling report data and calculating the costs required in drilling
planning. Then a solution is used by using Dog Leg Reamer in overcoming
obstacles in drilling the next wells by selecting through the costs required in its use.
Reevaluation of the drilling results that have used the Dog Leg Reamer is carried
out.
Based on the results of the research conducted, the cost of tripping and casing
installation activities at the “SR-11” well amounted to Rp 2.742.840.000,00. In the
SR-12, SR-13, and SR-14 wells, the Dog Leg Reamer was used as a solution to
obstacles in drilling activities. The cost of the drilling results in the tripping and
casing installation activities of the “SR-12”, “SR-13”, and “SR-14” wells was
found to be Rp 1.162.900.000, Rp 1.283.200.000, and Rp 1,090,720,000. With the
calculation of the difference in costs required in the four wells, it was concluded
that drilling with the Dog Leg Reamer was successfully used.
