Abstract

Damage to roads in the Balikpapan area is a problem that recurs every year. The patchwork project is a scene in itself at the locations where roads are damaged. The causes of road damage have long been studied by researchers from the civilian field. Research related to the road structure and the underlying rock engineering conditions has been carried out. The purpose of this research is to prove that apart from the influence of the characteristics of the road structure and its rocks, the effect of geological fractures can also be considered. This study uses the main data to measure the direction of the road cracks and the direction of the geological fault. The data is then analyzed how far it affects one another. Based on the measurement data of the direction of the cracks on the highway and the drawing of geological structure straightness through satellite images which are then compared, the results show that there are similarities in the direction of the cracks and the geological structure in Balikpapan. These directions are Northwest - West - Southwest with Southeast-East-Northeast. Therefore, it can be concluded that the effect of cracks on the road has a direct influence on the geological structure in Balikpapan.

Abstract

Lost circulation is a critical drilling problem that causes drilling fluid to enter the formation, triggering wellbore instability and higher operational costs. In the ZR Well, a severely depleted zone (1.7 ppg) at approximately 7,200 ft depth carries a high risk of total circulation loss. This study evaluates the effectiveness of various concentrations of multimodal Loss circulation material (LCM), combining Safecarb, Quick seal fine, and G-seal plus, in reducing fluid loss in a 10.5 ppg Synthetic Oil-Based Mud system. The method used secondary data from Permeability plugging test (PPT) results under HTHP conditions (280°F, 2,000 psi differential pressure, 60-micron ceramic disk) with total additive concentrations ranging from 2.5 to 10 ppb. Results show that increasing LCM concentration consistently reduced filtrate volume, with the best performance at 10 ppb (spurt loss 1.0 mL; total fluid loss 8.2 mL), producing a thin, dense, and impermeable filter cake. The 10 ppb formulation is recommended as the optimal solution for mitigating loss circulation in the ZR Well.

Abstract

Analisa beban torsi dilakukan untuk meminimalisir terjadinya permasalahan-permasalahan seperti penelitian ini yang akan melakukan analisa perbandingan beban torsi dan pengaruh side force pada pemboran sumur berarah tipe J dan tipe S. Adapun hasil dari analisa, didapatkan bahwa beban torsi akan mengalami percepatan kenaikan yang signifikan pada interval kick off point dan drop off point yang mana pada bagian ini tepat merupakan busur kelengkungan dan beban torsi akan cenderung bernilai stabil yang mana hal ini terjadi pada bagian tangent section yang bukan merupakan busur kelengkungan. Dari hasil simulasi software didapati nilai beban torsi pada sumur berarah tipe J sebesar 22.62 kft.lbf dan untuk sumur berarah tipe S sebesar 31.74 kft.lbf. side force akan tinggi disebabkan karena adanya busur kelengkungan dengan nilai dogleg Severity (DLS) yang cenderung tinggi hal ini disebabkan karena keadaan formasi, jenis BHA, mata bor, dan drilling parameter. Kemudia side force yang terlihat konstan karena nilai dogleg severity (DLS) dipertahankan namun terlihat zig- zag karena adanya efek tortuosity.
