Drilling optimization objective was to reduce costs, improve wellbore conditions and integrity for increasingly challenging reservoirs while establishing maximum safety performance and environmental custodianship. Even though the final result of a drilling operation is easily observed, what almost always goes unnoticed is the complexity of the issues involved in the planning and execution of a drilling operation and the number of topics involved in such a process. In this paper, as case study of the exploration drilling in Hamada region, North Africa has been evaluated. Over the period of 2006 to 2011, continued drilling improvement was achieved. Key elements in the optimization included focus on management drilling team structure, engineering well planning, improvements on managing drilling operations such as on site safety management practices, and also post drill analysis to implement lesson learn for the next well to be drilled. As the result, while drilling 26 wells during the 2006 until 2011, drilling days were successfully reduced from 87 days (first well) to the average 40 days, and very good safety record performance.

Well X is located in the offshore Y field, where there are 7 production wells, all of which use an artificial lift in the form of a gas lift. In this field, oil is produced from the N oil layer while the gas layer comes from the K layer. Well X was drilled in May 2013 with a target of N oil formation at a depth of 9,007 ft MD, slope (450) and 4-1/2" Liner completion. The initial production of well X was 1,632 BOPD; 5.3 MMSCFD; 0% BSW. Well X is the only well in the Y offshore field that does not penetrate the K gas formation, so gas production from nearby wells is used to produce oil from the N formation. well-to-well gas lift. Along with production time, the reservoir pressure in the N oil layer and K gas layer has decreased, so that oil production in well X has also decreased. With changes in company policy that optimize and increase gas production to increase gas sales to the industry around the company's operational areas since early 2017, the outgoing pressure on the Y platform has increased from 210 psi to 450 psi, causing a total oil well X could not pass through and produce due to high outgoing pressure on platform Y. Well X's last production data was on January 31 2017 with oil production of 179 BOPD and 1.25 MMSCD for gas production and gas lift injection of 0.75 MMSCFD, before finally shutting down. The selection of another artificial lift as a substitute for the gas lift has been carried out to revive well X later. Based on the alloy table made by Weatherford for the selection of artificial lifts for conditions on the Y field platform, ESP has many advantages and appropriate flexibility compared to other types of artificial lifts. The ESP type D1050N which is a mix flow ESP has been selected and after installation in well X in August 2019 it has successfully revived with a production test of 885 BFPD, 681 BOPD, and 23% water content on September 3 2019. ESP in well X has been in production for 2 years, until finally experiencing a leaky tubing problem in September 2021 and requiring a new tubing replacement job along with a new ESP replacement to revive the X well.

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.

This study discusses the design planning of the Bottom Hole Assembly (BHA) in J-type directional drilling with a focus on the effect of variations in Outer Diameter (OD) and stabilizer position on the well trajectory characteristics. The method used is a drilling planning simulation using WellPlan software on Well X with variations in Outer Diameter (OD) of the stabilizer of 10¾”, 11”, and 12”, as well as variations in the distance of the stabilizer installation from the drill bit, while other drilling parameters are kept constant. The main evaluation parameters include Build Up Rate (BUR) and Dogleg Severity (DLS). The simulation results show that increasing the Outer Diameter (OD) of the stabilizer results in an increase in the Build Up Rate (BUR) value represented by the Equilibrium Build Rate (EBR). In addition, the stabilizer installed closer to the drill bit shows a higher trajectory angle formation capability. The results of this study indicate that the selection of the right Outer Diameter (OD) and stabilizer position plays an important role in controlling the well trajectory and can be used as a reference in planning the design of the Bottom Hole Assembly (BHA) in J-type directional drilling.

This study discusses the application of the Leverett J-Function method in the process of normalizing capillary pressure (Pc) data from SCAL tests on centrifuges in reservoir rocks to obtain more accurate rock characteristics, and focuses on understanding the relationship between capillary pressure, water saturation, porosity, and permeability which play an important role in determining fluid distribution and flow quality in reservoir rocks. The focus of this study is directed at assessing the relationship between Pc and Sw, grouping rock characteristics using the Hydraulic Flow Unit (HFU) method, and applying Leverett J-Function to normalize data so that measurement results from various samples can be compared consistently. The results show that rocks can be grouped into three HFUs with varying flow quality, where HFU 1 shows the best quality, HFU 2 represents medium flow, and HFU 3 has low quality. Normalization using Leverett J-Function successfully unifies capillary pressure data into a more uniform curve, while the denormalization results provide a more realistic picture of reservoir conditions. The combination of HFU and Leverett J-Function methods has proven effective in improving the accuracy of petrophysical interpretations and supporting oil and gas reservoir management.

This study is based on initial findings indicating Cu-Au minerals in altered igneous rocks in the prospect zone around Sumbawa. The main problem studied is how outcrop, petrology, mineralogy, hydrothermal alteration, and geochemistry data can be used to reconstruct the relationship between rock petrogenesis and ore mineral formation. The approach used is a synthesis of research data with nearby regional analogs from the Sumbawa segment and the eastern Sunda arc, so that interpretation does not depend on a single mine site, but on the geological, petrologic, and metallogenic patterns that have been documented in the area. The data evaluated include outcrop indications of porphyritic igneous rocks, quartz-sulfide veins, potassic to propylitic alteration, petrography-XRD-SWIR-based identification of alteration minerals, chemical characteristics of intermediate-felsic rocks, and geochemical patterns of Cu, Au, Mo, Ag, As, Pb, Zn, and other trace elements. The synthesis results show that Cu-Au indications are most consistently explained as part of a porphyry-type magmatic-hydrothermal system, which developed in the Sunda-Banda subduction arc environment. The hydrous, relatively oxidized arc magma, which evolved towards tonalite-quartz diorite, became the source of heat, fluids, and metals. The release of magmatic-hydrothermal fluids then produced quartz-sulfide stockworks, chalcopyrite-bornite-pyrite mineralization, as well as potassic, phyllic/chlorite-sericite, argillic, and propylitic alteration zones. The integration of these data allows the development of a more systematic genesis model while providing the basis for exploration vectorization from the distal alteration zone to the mineralization center.
