Abstract

Pada penelitian ini, peneliti menganalisis pengaruh serbuk kopi terhadap rheology lumpur dan filtration loss dengan variasi konsentrasi 3 gr, 5 gr, 7 gr. Adapun tujuan penelitian ini untuk mengetahui pengaruh serbuk kopi sebagai lost circulation material untuk menanggulangi terjadinya filtration loss serta mengetahui pengaruh serbuk kopi terhadap rheology lumpur pemboran. Metodologi penelitian dilakukan dengan skala laboratorium. Hasil penelitian menunjukkan bahwa pengaruh serbuk kopi sebagai lost circulation material untuk menanggulangi terjadinya filtration loss dari pembuatan sampel A-D sesuai dengan rekomendasi standart API dikarenakan seiring dengan penambahan serbuk kopi dapat mengurangi nilai filtrat dari lumpur yang awalnya 7.6 ml (Sampel A) turun menjadi 5.4 ml (Sampel D). jadi dapat disimpulkan penambahan serbuk kopi dapat menanggulangi terjadinya filtration loss, selain itu serbuk kopi juga mempengaruhi rheology lumpur pemboran yakni seiring dengan penambahan serbuk kopi dari sampel A-D menunjukkan kenaikan. Untuk mengatasi filtration loss tersebut, lumpur pemboran yang digunakan harus memiliki kandungan beberapa jenis komponen yang berfungsi menyumbat lubang terbuka di batuan. Penelitian ini berfokus pada pemanfaatan serbuk kopi sebagai lost circulation material untuk menanggulangi terjadinya filtration loss, serta pengaruhnya terhadap rheology lumpur pemboran. Penelitian ini bersifat experimental study pada laboratorium STT MIGAS Balikpapan.

Abstract

The phenomenon of water coning in oil and gas wells can lead to an undesired increase in water production, reducing hydrocarbon recovery efficiency. Determining the critical production flow rate is an essential step in controlling water movement into the production zone. This study analyzes the parameters influencing the critical flow rate, including reservoir characteristics, fluid viscosity, and well geometry. The methods employed include mathematical modeling and numerical simulations to identify the optimal production limits without triggering water coning. The results of this study provide guidance for petroleum engineers in managing well production efficiently and minimizing the negative impact of excessive water production.

Abstract

Productivity or commonly called productivity index (PI) in a well will decrease. Marked by a decrease in reservoir pressure (Pr), well flowing pressure (Pwf) and rate (Q) in the "Jose-1" well also decreased due to deposits (Scale) formed in the production zone, thus inhibiting Pr, Pwf and Q. Therefore, the solution that can be done to overcome this problem is well stimulation. The purpose of well stimulation in the "Jose-1" well is to overcome the deposits (Scale) formed so that Q increases. The deposits (Scale) formed can be identified by formation water parameters using several methods, one of which is the Stiff and Davis method with the Scaling Index (SI) parameter obtained. The stimulation method used is the matrix acidizing method, the success parameters of the matrix acidizing method can be seen from the Inflow Performance Relationship (IPR) parameters before and after as well as the PI before and after. This Final Assignment writing is done using manual calculations via excel. Based on the results of the analysis carried out, the "Jose-1" well experienced a decrease in pressure and production flow rate caused by CaCO3 deposits (Scale), proven by the SI value parameters using the Stiff and Davis method where SI> 0 (Tends to precipitate or precipitate CaCO3) which is 1.13 and a skin value of 12.5. After acid injection was carried out on the well, the oil rate (Qo) from 90 bopd increased to 144,539 bopd.

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

This study investigates the effect of temperature on the properties of KCl polymer-based drilling mud, focusing on maintaining the stability of these properties under varying temperature conditions. Five sample variations were tested: Sample A at room temperature, Sample B1 at 150°F, Sample B2 at 200°F, Sample B3 at 250°F, and Sample C at 250°F with the addition of selected additives. The B series samples showed a decline in mud quality as temperature increased, with Sample B3 falling outside the required specification limits for plastic viscosity, yield point, gel strength, and API filtrate due to high-temperature effects. To address this, additives were introduced in Sample C to enhance the composition and stabilize the mud properties. As a result, Sample C met the required specifications with plastic viscosity of 14 lbs/100ft², yield point of 32 lbs/100ft², gel strength of 9 lbs/100ft² after 10 seconds and 12 lbs/100ft² after 10 minutes, and API filtrate of 5.2 cc/30 minutes. The mud properties must be maintained to prevent hole problems in the formation during drilling operationsKeywords : Mud Fluid, Mud Properties, Tempreature

Abstract

Pipeline redesign was conducted at the LPG filling and distribution station of PT. Mashud Bersaudara Internasional to address excess pressure in the piping system during the LPG filling process on the filling skid. This research aims to analyze the pressure changes in the Sihi pump output pipe subsequent to the installation of a larger Sihi pump on the LPG filling skid line. Pressure changes in the pipe were analyzed using the continuity and Bernoulli equations. The research results indicated that the pressure increase, which triggered the activation of the pressure safety valve in the return pipeline, was due to the replacement of the Sihi pump with a larger capacity model. Prior to changing the size of the return pipe, the pressure was 8.535 Bar. After the replacement, the pressure in the Sihi pump output pipe dropped to 7.5525 Bar, which is below the pressure threshold of the pressure safety valve. Thus, the pipeline redesign successfully resolved the excess pressure issue.

Abstract

The Sucker Rod Pump installed in the TMT-Y Field X experienced a decrease in production because the pump capacity that has been used for a longer tim e is no longer in accordance with the pump capacity. From the initial data the production rate was known to be 350 bpd, judging from the production capacity of the TMT-Y well in Field X, the value of Qmax was 415.55 bpd and the productivity index value of 1.1 into the classification of medium well performance, the well still has the potential to produce more. Therefore, performing pump optimization calculations to increase productivity, the previous method I used was optimization of five scenarios. This optimization is carried out using five scenarios, in scenario 1 using a 2- inch plunger with 5/8 and 7/8 inch rods to calculate the pump optimization in scenario 2 using a 2 inch plunger and 5/8 and 7/8 inch rods. The production rate in scenario 1 is 365.7 bpd, the pump stroke length is 94 inches and the pump speed is 7.4 spm. the results of scenario 2 obtained a production rate of 370.7 bpd, a pump stroke length of 91 inches and a pump speed of 6.6 spm. In the results of scenario 3, a production rate of 368.7 bpd a pump stroke length of 90 inches and a pump speed of 6.5 spm was obtained in scenario 4 the results obtained a production rate of 367.6bpd, 76-inch pump stroke length and 5.5spm pump speed. The result of scenario 5 cannot be used the results of the intersection and the flow rate. Among the five scenarios, the best scenario is scenario 2, because if you look closely, the production rate increases from the initial production flow rate, which is from 350 bpd, which is higher to 370.7 bpd.
