Abstract

Reservoir gas ketat adalah salah satu jenis reservoir tidak konvensional yang saat ini banyak dikembangkan untuk memenuhi permintaan energi dunia. Seperti reservoir tidak konvensional lainnya, jenis ini dicirikan oleh permeabilitas matriks ultra-ekstrim rendah. Banyak metode telah dikembangkan untuk lebih memahami dan memprediksi perilaku reservoir ini, salah satunya adalah analisis kurva penurunan. Masalahnya adalah metode tradisional seperti metode Arps tidak dapat diterapkan pada reservoir ini. Duong (2011) mengembangkan analisis kurva penurunan yang akan bekerja pada periode transien atau perilaku reservoir gas yang ketat. Studi ini berfokus pada pendekatan Duong untuk menganalisis kinerja reservoir gas yang ketat berdasarkan analisis kurva penurunan. Model reservoir dikembangkan menggunakan simulator reservoir untuk menghasilkan sejarah produksi selama lima tahun. Total 6 kasus telah dikembangkan yang terdiri dari sumur horizontal dan vertikal dengan 3 nilai permeabilitas berbeda untuk masing-masing sumur. Data produksi kemudian dievaluasi, dan kinerja masa depan diprediksi menggunakan pendekatan Duong. Hasilnya, masing-masing sumur mampu menghasilkan lebih dari 40 tahun sebelum mencapai tingkat produksi minimum. Patahan hidrolik diperlukan untuk mendapatkan hasil maksimal selama produksi dari reservoir gas yang ketat.

Abstract

Nipah-Nipah plants grow mostly in the confluence of rivers and seas. This plant has the potential to maximize all parts of the tree. Nipah fruit can be used for Nata Frutican and the basic ingredients for making flour. Unused fruit shells have a hard texture, similar to the texture of coconut shells. To increase the calorific value of this fruit peel charcoal, a pyrolysis process is carried out. The samples were separated from the following waste and dried in direct sunlight. The dry sample is crushed and then put into the combustion reactor. Pyrolysis was carried out at a constant temperature of 500°C with variations in the heating rate of 2°C/minute, 4°C/minute, 6°C/minute, 8°C/minute, and 10°C/minute and holding time for 1 hour. The results showed that the calorific value decreased with increasing heating rate. The highest calorific value is at the lowest heating rate. The calorific value at a heating rate of 2°C/minute is 6841, 02 cal/gram. ; 4°C/minute calorific value is 6811.59 cal/gram; 6°C/minute of 6745.07 cal/gram; 8°C/minute is 6656.59 cal/gram and at 10°C/minute is 6570.41 cal/gram

Abstract

Production planning system is important thing in development phase of oil and gas field. The function is to transport of fluid from reservoir to surface facility until sales export point. In production system, one critical phase is determined production tubing that allow to accommodate optimum production rate both when well flow with natural flow or using artificial lift. Nodal analysis is common method that use to plan of production system. This method can give comprehensive view about whole integrated system. In this research, nodal analysis is used to determine optimum tubing size considering pressure profile that occurs in wellbore. Beggs & Brill method is used after comparison between available empiric and analytic model. This based on from model of flow regime in tubing when the well have big oil and gas ratio. The result of This research shown that tubing size determination have variation between wells. Well 1 will be effective using 4.5” tubing size, well 2 will be effective using 2.375” tubing size and well 3 will be effective using 2.375” tubing size. This determination based on performance curve for individual tubing size to production rate and considering changing in pressure curve (gradient transverse)

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

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.
