Abstract

The well "ZL" is located in the Tarakan field which at the beginning of production did not use an Artificial Lift. However, these wells will experience a decrease in production rates due to lower reservoir pressure and increased water cut levels. An Artificial Lift is needed to help lift the fluid to the surface. The Artificial Lift chosen for the “ZL” well is the Electrical Submersible Pump. In the initial step of ESP design, the method used was appropriate to the field conditions "YY", namely the Vogel Method. Next determine the amount of pump efficiency (% EP) and perform optimization on the ESP pump by changing the operating frequency. The “ZL” well has a maximum flow rate of 3347.9 BFPD with a target flow rate of 2343.53 BFPD. Based on the target flow rate in the “ZL” well, it is recommended to use a REDA D2400N 60Hz pump. Furthermore, from the optimization results at a frequency of 50 Hz, a production rate of 1180.8 BFPD with 59% EP was obtained, at a frequency of 55 Hz, a production rate of 1659.6 BFPD with 66% EP was obtained, at a frequency of 60 Hz a production rate of 2346.8 BFPD was obtained with % EP 68%, at a frequency of 65 Hz the production rate was 2846.2 BFPD with% EP 64%, and at a frequency of 70 Hz the production rate was 3266.4 BFPD with% EP 60%. From the results obtained that the frequency of 60 Hz with a production rate of 2346.8 BFPD and% EP 68% were selected based on Best Efficiency.

Abstract

Sumur “CM” mengalami penurunan performa produksi akibat berkurangnya tekanan reservoir dan meningkatnya rasio air dalam fluida produksi. Untuk mengoptimalkan kembali performa sumur tersebut, dilakukan perancangan sistem Electrical Submersible Pump (ESP) sebagai metode angkat buatan. Desain sistem ini mempertimbangkan parameter teknis seperti laju alir fluida, tekanan dasar sumur, viskositas, kandungan gas dan air, serta kedalaman sumur. Kurva Inflow Performance Relationship (IPR) tiga fase digunakan untuk memprediksi potensi produksi, sedangkan grafik kehilangan tekanan dan kurva performa pompa digunakan untuk pemilihan komponen ESP. Di samping itu, aspek kelistrikan juga dianalisis secara terintegrasi, meliputi pemilihan jenis kabel berdasarkan arus dan batas penurunan tegangan, transformator berdasarkan daya dan tegangan operasi, serta switchboard berdasarkan kapasitas arus dan daya maksimum. Hasil perancangan menunjukkan bahwa integrasi antara sistem ESP dan sistem kelistrikan yang tepat dapat meningkatkan efisiensi produksi dan meminimalkan risiko gangguan operasional. Dengan demikian,  penerapan  ESP terbukti sebagai  strategi  optimasi  produksi  yang efektif dan layak diterapkan pada sumur “CM”.

Abstract

This study aims to evaluate the performance of the C-3-08A separator used in a hydrocracking unit within an industrial processing facility, in support of increased production targets. The primary focus is to calculate and analyze the Area Ratio (Rm), which represents the ratio of the separator's length to its inlet diameter, ensuring efficiency in the fluid separation process at a flow rate of 13,435 BFPD. The method applied involves manual calculations to determine the Rm value and propose improvements to the separator design based on parameters such as length and flow rate. Analysis results show that the initial Rm value of 2.527 does not meet the standard requirement, which stipulates an Rm range between 3 and 5. Recalculation suggests that extending the separator length to 36 ft yields an Rm of 3.015, meeting the standard. Additionally, reducing the flow rate to 8,000 BFPD while maintaining a separator length of 30.183 ft and diameter of 10.045 ft produces an Rm of 3.004, also within acceptable limits. In conclusion, recalculating and adjusting the separator design parameters can enhance fluid separation efficiency and support increased production outcomes.

Abstract

The length of time to produce reservoir fluid will definitely experience a decrease in the production rate. The decrease in production rate can be caused by inappropriate tubing sizes and Damage to formations that impede fluid flow.To overcome the decline in production rates, it is necessary to choose the appropriate tubing size and carry out acidizing activities. Appropriate tubing size can avoid pressure drop and extend the life of the well. Acidizing is the injection of acid to eliminate the effect of decreasing permeability. The tubing size of 2 7/8 inches is not suitable for the “REDD-24” well because the target Qopt value of 130.997 bfpd was not achieved and there was an indication of calcium carbonate scale in the formation. This study discusses production optimization by re-designing tubing id after acidizing. Calculating the inflow performance relationship (IPR) using the Wiggin's method and obtaining Qtmax results of 163.74583 bpd, calculating theProductivity Index (PI) of 0.0870911 psi which according to Kermit E. Brown, the PI value is classified as low, calculates the skin value and obtains the results (+) 37.35 which indicates that the formation of the "REDD-24" well has suffered formation Damage. Selection of tubing with Hagedorn & Browns's correlation, analyzing Qopt tubing sizes of 3 1/2 inches, 2 inches, 1 2/3 inches, and 1 1/3 inches. Choose tubing with a size of 1 1/3 inches. matrix acidizing planning by knowing the value of formation fracture pressure (Pf) of 4857 psi, maximum  injection rate (Imax) of 2.829 bbl/min, maximum injection pressure (Pmax) of 1318.24, injected acid volume of 42.13561 bbl, and knowing success rate.

Abstract

The difficulty of finding efficient boarding houses, especially for students and lower-income workers in Palopo City, remains a major problem due to limited centralized information. The weakness of existing property e-commerce platforms is the lack of integration between spatial location precision and personalized recommendations. This study aims to develop a web-desktop-based boarding house e-commerce system that addresses this weakness by integrating Leaflet Spatial Visualization technology and the GeoAI Recommendation Algorithm. The system development method used is Agile Development with the Scrum model. The Leaflet.js library is used to interactively present boarding house distribution data on a map of Palopo City, complete with dynamic room availability markers. Meanwhile, the GeoAI recommendation feature is implemented using Content-Based Filtering and Collaborative Filtering algorithms to present a personalized list of accommodations based on the user's search history and location preferences. The result of this study is an integrated boarding house e-commerce platform that can improve the user experience in finding accommodations that meet spatial criteria and facilities. The implementation of this system is expected to accelerate the digitalization of boarding house services in Palopo City and become a model for the development of similar applications in the local property sector.
