Abstract

t - Shale is one of the rocks that often causes drilling problems because shale tends to swell or swell when
in contact with mud fi ltrate, mainly Water-base Mud (WBM). This study aims to determine how the performance of
Oil-base Mud (OBM) based on Crude Coconut Oil (CCO) in overcoming the swelling problem. The methodology used
consists of drilling simulation and cutting analysis in the X-Ray Diffraction (XRD) laboratory. The series of activities
in the study began with the preparation of rock layers, followed by testing the penetration rate using Water-base Mud
as a comparison. After cutting analysis was carried out in the XRD laboratory of UPN “Veteran” Yogyakarta with the
Rigaku tool, then replaced the type of drilling fl uid Oil-base Mud with basic materials alternative to Crude Coconut
Oil (CCO) and followed by a penetration test. Rate of Penetration (ROP) test results from WBM with Rheology 1 at
interval A or a depth of 1.96 ft-4.92 ft is 442.8 ft/h, Rheology 2 at interval B or a depth of 4.92-10.5 ft is 118.5 ft/hr on
the fi rst day. Swelling occurred and resulted in pipe sticking at depth of 6.5 ft. Based on the Bulk Mineral analysis, clay
mineral content is 23.84%. Based on the Clay Oriented, smectite dominates the clay by 29.09%. Based on MBT, shale
belongs to class B (illite and mixed-layer montmorillonite illite), where this mineral can expand. Based on a Geonor
As test, 5.18% of the cutting can develop when exposed to water. The drilling fl uid was replaced with Oil-base Mud
based on alternative Crude Coconut Oil (CCO), and obtained ROP Rheology 1 at Interval A of 492 ft/h and Rheology
2 at Interval B of 480 ft/h. The results of the Compressive Strength test interval A on the fi rst, third, and fi fth days were
31,699 psi, 42,265 psi, and 52,831 psi. The results of the Compressive Strength test interval B on the fi rst, second, and
third days were 31,496 psi, 41,517 psi, and 52,971 psi. Based on clay mineral analysis and magnitude of ROP value,
is known that Crude Coconut Oil (CCO) based Oil-base Mud is effective because during the simulation, there are no
drilling problems, and the resulting ROP value is greater than the fi rst day Water-base Mud.
