Abstract

Proses bottom up circulation adalah tahapan di mana lumpur pemboran dipompa ke dalam lubang bor dari permukaan hingga ke dasar lubang, kemudian dialirkan kembali ke atas. Penelitian ini bertujuan untuk mengevaluasi pelaksanaan sirkulasi bottom up pada Trayek 8 ½ inci Sumur X di Lapangan Y yang merupakan sumur pemboran berarah. Fokus utama evaluasi adalah membandingkan waktu sirkulasi hasil perhitungan teoritis dengan data aktual lapangan, serta menganalisis penyebab perbedaan yang terjadi. Data yang digunakan meliputi spesifikasi sumur, Drill string, pompa lumpur, dan data actual lapangan. Hasil perhitungan menunjukkan bahwa waktu sirkulasi teoritis sebesar 28,6362 menit dengan jumlah 2.625,0910 Stroke, sedangkan waktu aktual tercatat 33 menit dengan 3100 Stroke. Selisih waktu dan Volume sirkulasi tersebut mengindikasikan adanya pelebaran lubang bor (overgauge Hole), Penyebab utama pelebaran ini antara lain efisiensi pompa yang tidak optimal, karakteristik formasi yang tidak stabil, serta potensi terjadinya washout di sekitar BHA

Abstract

Magmatism and volcanism represent two fundamental geological processes that play a crucial role in the internal dynamics of the Earth and the formation of igneous rocks. Magmatism encompasses all processes related to magma generation as a result of partial melting of the mantle or crust, including magma migration, differentiation, and crystallization beneath the Earth's surface. Volcanism, in contrast, constitutes the surface expression of magmatic activity, occurring when magma ascends through volcanic conduits and erupts at the surface, producing lava flows, pyroclastic materials, and volcanic gases. Although genetically related, these processes differ significantly in their spatial occurrence, mechanisms, and geological products. This study aims to elucidate the conceptual and process-based differences between magmatism and volcanism and to examine their interrelationship within the Earth’s geodynamic system. The research adopts a literature-based methodology, reviewing peer‑reviewed publications from accredited national and international journals in geology and volcanology. Secondary data analyzed include studies on magma generation, magma chamber dynamics, intrusive magmatic systems, and volcanic eruption mechanisms as addressed in contemporary geological research. The results indicate that magmatism predominantly occurs beneath the Earth’s surface and forms intrusive bodies such as batholiths, laccoliths, sills, and dikes through magma crystallization before reaching the surface. Volcanism, on the other hand, represents the extrusion of magma at the surface and plays a fundamental role in the development of volcanoes and volcanic landscapes. A comprehensive understanding of the relationship between magmatism and volcanism is essential for interpreting crustal evolution, mineral resource exploration, and the mitigation of geological hazards associated with volcanic activity.

Abstract

This study aims to analyze the effect of bentonite addition on the rheological properties of drilling mud using KCL (potassium chloride) polymer at temperatures of 100°F, 200°F, and 250°F. Drilling mud with bentonite and KCL polymer is important in the oil drilling industry because it affects well stability and drilling efficiency. The research method is qualitative with laboratory testing using a viscometer to measure rheological parameters such as plastic viscosity, yield point, and gel strength at various temperatures. The results showed that the addition of bentonite increased the rheological stability of the mud, especially at temperatures of 100°F and 200°F, with more optimal viscosity and gel strength values. However, at a temperature of 250°F the rheological performance decreased due to degradation of the KCL polymer and changes in the bentonite gel structure. The conclusion of this study states that the use of bentonite can improve the rheological properties of KCL-based mud at low to medium temperatures, but is less effective at high temperatures. This research provides important insights for more effective and stable drilling mud formulation in the field.

Abstract

This study evaluates the effectiveness of the application of the driller's method on the 6-1/8" trajectory of the X well in the Y field using secondary data from drilling operations, namely the values ​​of SIDPP, SICP, ICP, FCP, mud volume, pump data, and Leak-Off Least (LOT) results. The method used is quantitative analysis and well control calculations carried out through the following stages: determining formation pressure, calculating Initial Circulating Pressure (ICP), Final Circulating Pressure (FCP), Kill Mud Weight (KMW), and evaluating the formation safety limit through MAASP and MADFD. The results showed that the actual mud weight of 14.2 ppg was underbalanced against the equivalent formation pressure of 14.5 ppg, thus triggering a kick. The calculation resulted in an ICP of 270 psi, FCP of 243 psi, and KMW of 14.39 ppg, while the LOT of 2195 psi indicated that the formation capacity was still safe for the circulation process. The evaluation concluded that the Driller's Method was effective and safe for use in mitigating kicks without causing lost circulation. as well as formation damage.
