Abstract

The SLN field is a field that has several fields and produces fluids using artificial lift, specifically electrical submersible pumps (ESP). The objective of this research is to obtain the latest recommended value for fluid above the pump (FAP) by evaluating the FAP in each field within the SLN field. This will help determine the minimum fluid above the pump as a reference for future operations in the SLN field. In this study, the method used to calculate the fluid above the pump involves interpolating the FAP data with casing pressure, gas production, and gas-oil ratio (GOR) data. This is done to obtain the best regression graph and determine the minimum FAP value. Based on the research conducted on the evaluation of fluid above the pump in the Dik 01 and Dik 02 fields, the results for the Dik 01 field indicate that when the FAP is low, the gas production rate (Qg) and GOR are also low, indicating the absence of free gas. Conversely, when the FAP is high, there is an indication of free gas. The minimum FAP values obtained for the Dik 01 field are 1918 ft for Qg (Mscf/d) and 1967.44 ft for GOR (scf/stb). The results for the Dik 02 field show that a high FAP value corresponds to a low Qg and GOR, indicating the absence of gas. Conversely, a low FAP value corresponds to a high Qg and GOR, indicating the presence of free gas. The minimum FAP values obtained for the Dik 02 field are 3895 ft for Qg (Mscf/d) and 3776.32 ft for GOR (scf/stb).

Abstract

The behavior of petroleum reservoirs is inherently complex, making it challenging to determine their performance for both single-fluid and multiphase production systems. To accurately estimate the recovery reserves of a reservoir, a comprehensive understanding of its geometry and internal flow characteristics is essential. Numerical simulation serves as a fundamental tool for reservoir engineers, offering an efficient and reliable method to predict reservoir mechanisms, evaluate pressure variations, and estimate in-place hydrocarbon yield. This study employs mathematical modeling concepts and numerical techniques to analyze the dynamic behavior of petroleum reservoir systems. A flow model based on Partial Differential Equations (PDEs), specifically the diffusivity equation for unsteady-state fluid flow in porous media, is developed and applied. The diffusivity equation is discretized and solved mathematically using the explicit finite difference method to approximate pressure distribution over time and space. The primary objective of this research is to investigate and analyze the pressure distribution that governs reservoir performance under varying conditions. Sensitivity analyses are conducted to evaluate the influence of grid spacing, time step, hydraulic diffusivity, and boundary conditions on pressure reservoir behavior within a Cartesian grid for a one-dimensional, single-phase reservoir. The findings are expected to provide insight into the relationship between reservoir properties and fluid dynamics, supporting improved prediction of reservoir behavior. Ultimately, this research contributes to the optimization of petroleum production strategies and enhances the understanding of reservoir engineering processes through quantitative simulation.

Abstract

Penurunan tekanan reservoir secara alami menyebabka penurunan produksi fluida dari sumur minyak, sehingga penerapan metode pengangkatan buatan seperti Electric Submersible Pump (ESP) menjadi penting untuk mempertahankan dan meningkatkan laju produksi. Penelitian ini bertujuan untuk mengevaluasi dan mengoptimasikan kinerja pompa ESP pada sumur FT – 08 dilapangan TF yang mengalami penurunan efisiensi volumetric di bawah standar operasi optimal. Evaluasi dilakukakn dengan menghitung kurva Inflow Performance Relationship (IPR) menggunakan metode Vogel dan parameter produktivitas sumur, serta menganalisis efisiensi volumetric pompa dengan parameter desain dan operasional ESP seperti tekanan intake, total dynamic head (TDH), dan laju alir fluida actual. Hasil evaluasi menunjukan bahwa kurva IPR menghasilkan laju alir teoritis sebesar 619,37 BPD dengan tekanan dasar sumur (Pwf) 233,86 psia, sedangkan efisiensi volumetrik aktual pompa mencapai 84% yang meunjukkan adanya potensi optimasi. Berdasarkan hasil tersebut, penelitian ini merekomendasikan redesain atau penggantian pompa yang lebih sesuai dengan kondisi aktual sumur untuk meningkatkan efisiensi produksi jangka Panjang.   The natural decline in reservoir pressure leads to a significant reduction in fluid production from oil wells, making the application of artificial lift methods such as the Electric Submersible Pump (ESP) essential to sustain and enhance production rates. This study aims to evaluate and optimize the performance of the ESP installed in Well FT-08 of the TF Field, which has experienced a decline in volumetric efficiency below the operational optimum. The evaluation was conducted by constructing the Inflow Performance Relationship (IPR) curve using the Vogel method and analyzing the well's productivity index, along with performance metrics such as pump intake pressure, total dynamic head (TDH), and actual flow rate. The IPR analysis yielded a theoretical production rate of 619.37 BPD at a bottomhole flowing pressure (Pwf) of 233.86 psia, while the measured volumetric efficiency of the installed ESP reached 84%, indicating the potential for further optimization. Based on these results, the study recommends redesigning or replacing the pump with a configuration better suited to the current reservoir and well conditions to enhance long-term production efficiency

Abstract

Indonesia has a large amount of liquid waste originating from the tofu industry. Currently, the treatment of tofu industrial wastewater is carried out using both anaerobic and aerobic methods, but both methods still have several weaknesses. In this study, the tofu industrial wastewater was utilized as a culture medium for Spirulina sp. to provide economic value from wastewater that can be used as bioethanol, pharmaceuticals, and food products rich in omega 3, chlorophyll, carotenoids. Aim: The growth of Spirulina sp. is closely related to the availability of macro and micronutrients as nutrients and the influence of environmental conditions, so this study was aimed to see the best variation of the addition of urea and NaHCO3 as additional nutrients to maximize growth and cell density of Spirulina sp. with tofu industrial wastewater media. Methodology and Results: This study was done by culvitating Spirulina sp in the growth media, measuring the Optical Density (OD), and analyzing quantitatively and using ANOVA on IBM SPSS Statistics version 20. The study indicated that adding urea and NaHCO3 to Spirulina sp. had no effect on cell density and growth rate. Treatment with addition of urea 0.36 g/500 ml without additional of NaHCO3 had the highest growth rate, 0.00852/day, and the highest cell density value on Spirulina sp. growth. Conclusion, significance, and impact study: The tofu liquid waste can be used as a new alternative used as fertilizer because in the liquid tofu waste, it provides the nutrients needed by Spirulina sp.

Abstract

Eco enzyme is a product of organic waste derived from vegetables and fruits, fermented with sugar in a container and allowed to stand for three months to become an active solution. The use of eco-enzyme as a natural cleaning solution contributes to protecting the environment because it treats household-scale organic waste. The community service program aims to enhance Cigombong Village's potential with a community that cares about the environment that has been formed. The eco enzyme can be used to clean all areas of the house, clothes, vegetables, and fruits, fertilize plants, eliminate pests, and improve the quality of plants; the eco enzyme is also very effective in repelling plant pests. The eco enzyme can also be utilized to stimulate plant hormones to enhance fruit and vegetable quality and improve crop yields. Making eco enzymes can be done simply, using easily available equipment. The raw materials for eco enzyme consist of brown sugar, water, and fruit peel waste in a ratio of 1:10:3. The container used for the eco enzyme is a plastic jar with a lid. A training program for making eco enzymes from fruit and vegetable peel waste can protect the environment, increase community plantation yields and make Cigombong village a fruit tourism village.
