Abstract

Sedimentation at the mouth of the Palu River is the cause of frequent flooding in Palu City. This study aims to understand the hydrodynamic conditions and longshore sediment transport around the mouth of the Palu River. Hydrodynamic conditions were analyzed by measuring velocity and current direction, salinity, discharge, breaking wave height, breaking wave depth, wave incidence angle, water density, and water depth. While the amount of longshore sediment transport was calculated based on the CERC empirical formula. The results revealed that the distribution of currents at the mouth of the Palu River was dominated by river currents, where the amount of seawater in the mouth of the river was small. This could be seen from the small salinity value, which ranged from 1 ‰ to 5 ‰. The longshore sediment transport around the Palu River estuary is 36.06 m3/day, where this sediment resulted in silting at the Palu River estuary during deposition.

Abstract

Global Warming is one of the environmental problems today. Efforts of anticipatons as a form of concern, have been carried out by various environmental movement programs, initiated by the government, NGOs and the community. In principle, environmentally friendly campus management is one of the determinants in producing the quality and quantity of the ongoing educational process. The purpose of this research is to study the application of an environmentally friendly campus using the fishbone diagram method to analyze the cause and effect of a problem. The results of the cause and effect analysis are then used as input to formulate internal factors in the SWOT, then produce strategies to minimize obstacles and increase the success of the green campus. This research is useful for educational institutions at STT Migas Balikpapan because it can provide an understanding of campus management policies that are oriented towards environmental management, in an effort to implement environmental education for students, as well as the care and involvement of all elements of the academic community in a culture of environmental care.

Abstract

Penelitian ini bertujuan untuk mengevaluasi kelayakan penggunaan pati jagung dan pati gandum sebagai additive alami pada sistem lumpur pengeboran berbasis air dengan KCl polymer. Fokus penelitian diarahkan pada pengaruh penambahan kedua bahan tersebut terhadap karakteristik reologi lumpur yang meliputi mud weight, plastic viscosity, yield point, dan gel strength, serta terhadap nilai filtration loss dan ketebalan mud cake. Metode penelitian dilakukan melalui pengujian laboratorium dengan empat variasi formulasi lumpur, yaitu lumpur dasar KCl polymer, lumpur dengan penambahan pati jagung, lumpur dengan penambahan pati gandum, serta lumpur dengan kombinasi kedua additive tersebut. Seluruh pengujian dilakukan pada suhu 120°F menggunakan peralatan standar berupa Fann VG Meter, Mud Balance, dan API Filter Press. Hasil pengujian menunjukkan bahwa penambahan pati jagung dan pati gandum memberikan pengaruh positif terhadap kestabilan lumpur pemboran secara keseluruhan. Pati jagung menunjukkan kinerja lebih baik dalam meningkatkan gel strength hingga 11 lb/100 ft² pada 10 detik dan 3 lb/100 ft² pada 10 menit. Sementara itu, pati gandum lebih efektif dalam menurunkan nilai filtration loss hingga 60 ml. Berdasarkan hasil penelitian, penggunaan pati jagung direkomendasikan untuk peningkatan kestabilan reologi, sedangkan pati gandum lebih sesuai digunakan sebagai pengendali filtrasi sesuai kebutuhan operasi pengeboran lapangan.

Abstract

Milling operations on the sand trap of Well X, Field Y—a mature field—face reduced cleaning efficiency due to uncertain pressure loss distribution within the Coiled Tubing Unit (CTU) circulation system. This study analyzes the magnitude of pressure losses, maps the specific locations of hydraulic energy depletion, and determines the optimal pump flow rate to establish a safe hydraulic window that prevents lost circulation. The method applied is a mathematical hydraulic analysis covering hydrostatic pressure, bit pressure loss (Pb), annular velocity (AV), and Equivalent Circulating Density (ECD), with sensitivity analysis across three pump flow rates (1.1, 1.2, and 1.3 bbl/min). Results show pressure losses accumulate at three critical points: inside the coiled tubing due to helical buckling, at the junk mill nozzle, and across the Positive Displacement Motor (PDM), which suffers wear from abrasive sand. A flow rate of 1.2 bbl/min (50.4 gpm) proved optimal, yielding an annular velocity of 184.24 ft/min—exceeding the minimum critical limit (>180 ft/min)—while maintaining ECD at 8.534 ppg, safely below the formation fracture gradient.

Abstract

Water injection is a method used to maintain reservoir pressure and improve hydrocarbon recovery efficiency. One of the common problems encountered in injection wells is formation damage, which can reduce the formation's ability to accept injected fluids. This study aims to evaluate the performance of Injection Well X using the Hall Plot method to identify formation damage and determine an appropriate remedial action.The research methods include Hall Plot analysis based on the relationship between cumulative water injection and cumulative pressure, as well as the calculation of the Injectivity Index (II) as a supporting parameter for evaluating well performance. The data used consist of injection rate, injection pressure, operating time, and well stimulation data from August to December 2017.The results show that the Hall Plot slope increased from 0,001115208 during the August–September period to 0.015021 during October–November, indicating the occurrence of formation damage. The Injectivity Index also decreased from 62.99 BWPD/psi to 16.88 BWPD/psi. To overcome this condition, a matrix acidizing treatment using 10% HCl solution with a volume of 5.05 bbl was conducted. After acidizing, the Hall Plot slope decreased to 0.008741, while the Injectivity Index increased to 33.43 BWPD/psi. These results indicate that matrix acidizing was effective in reducing flow resistance and improving the performance of Injection Well X.
