Abstract

To produce gas methane from the coal bed methane (CBM) field requires the right completion system that considers the reservoir properties which are encountered. One of technologies that is recommended to produce gas methane in the CBM field is Radial Jet Drilling System (RJD). Two important aspects which are considered to test the feasibility of RJD in the CBM field are the problems that usually show up while drilling and producing. The other aspects are the principle of RJD that considers several special tools like radial jetting and length of radial and the problems that usually present during RJD’s application in conventional field like water blocking, hole positioning and hole cleaning. To see the effectiveness of RJD, a comparison with other completion systems (vertical well) is done through simulation step by using WS field data, precisely at BP formation. CBM field simulation that is produced with vertical well system is sensed by adding wells. Meanwhile the CBM field that is produced by RJD completion is sensed by the number of radial phases and the length of each phase.The results show that RJD can be applied in the CBM well with certain parameters then the RJD effectiveness can be achieved with the minimum number of three phases, where the distance of each phase is 90 degrees and length of each radial phase is 300 until 500 ft.Key words: Completion, CBM, RJD, radial jetting, water blocking, hole cleaning, hole positioning, simulation, WS fieldABSTRAK Untuk memperoleh produksi gas metan pada lapangan CBM maka dibutuhkan sistem komplesi yang tepat dengan tetap mempertimbangkan karakteristik reservoir CBM yang dihadapi.  Salah satu teknologi yang di rekomendasikan untuk memproduksi gas metan pada lapangan CBM adalah Radial Jet Drilling (RJD).Dua aspek penting yang dipertimbangkan untuk menguji kelaikan RJD pada lapangan CBM ialah masalah yang biasa muncul pada saat pemboran dan pada saat proses produksi. Aspek berikutnya adalah prinsip kerja RJD yang mempertimbangkan beberapa alat khusus seperti radial jetting dan panjang radial, serta masalah yang biasa muncul seiring dengan aplikasi RJD pada lapangan konvensional seperti water blocking, hole position dan hole cleaning.Sementara untuk melihat keefektifan RJD maka dilakukan perbandingan dengan sistem komplesi lain (sumur vertical) melalui tahap simulasi dengan menggunakan data lapangan WS tepatnya pada formasi BP. Simulasi lapangan CBM yang diproduksi dengan sistem sumur vertikal di sensitivitas dengan menambahkan sumur. Sedangkan lapangan CBM yang diproduksi dengan sistem komplesi RJD di sensitivitas terhadap jumlah fase radial dan panjang masing-masing fase.Hasil pengujian menunjukkan bahwa RJD dapat diaplikasikan pada sumur CBM dengan parameter tertentu sedangkan efektifitas RJD dapat dicapai pada jumlah fase minumum 3 (tiga), dengan jarak antara fase 90o dan dengan panjang radial masing-masing fase 300 ft – 500 ft.Kata kunci : Komplesi, CBM, RJD, radial jetting, water blocking, hole cleaning, hole position, simulasi, WS.

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

The analysis conducted in this study focuses on the "AB-1" rig's ability to handle calculated loads. Results show that at 1,248 ft MD with 13 3/8" casing, the hook load and drawworks are both 84,864 pounds. At 5,818 ft MD with 9.5/8" casing, these values increase to 273,446 pounds. At 8,463 ft MD using dual 3.1/2 tubing, the load is 159,748.8 pounds. Mud pump power calculations reveal pressures of 681,408 psi for surface sections and 5,632.97 psi for production sections. Casing is a steel pipe inserted into a wellbore to prevent wall collapse, isolate abnormal pressure zones, and provide space for subsurface equipment during hydrocarbon production. This study aims to evaluate the casing load by analyzing hook load, drawworks, and mud pump power. Hook load represents the weight supported by the rig, including the accumulation of pipe weight, casing weight, and drag forces. Drawworks serve as lifting equipment for casing and tubing during drilling operations, while mud pumps circulate drilling fluids to support the process. Based on these findings, the "AB-1" rig is deemed suitable for operations with a hook load and drawworks capacity of up to 500 tons (1,000,000 pounds) and a mud pump pressure limit of 5,787 psi.

Abstract

As we know mud drilling provides many benefits in drilling operations. This needs to be considered also how the speed of the drilling mud is so in bringing drill powder above the surface so that there are no problems at will. The problem that occurs when the drill powder is not carried to the surface is the deposition at the bottom of the borehole. To see if the drilling sludge can circulate properly, it is necessary to calculate critical speed and average speed. Research data such as borehole diameter, mud weight, yield point, and plastic viscosity as well as data on each circuit component and annulus will be needed to determine flow patterns in circuits and annulus. Determination of flow patterns is also needed so that it can find out if the drilling sludge is functioning properly in the borehole. After doing calculations on the circuit then the vcDP result = 5.99 fps < V dp = 13.18 fps, VcMWD Tools = 6.28 < V MWD Tools = 26.82 fps, Vc3xDC = 6.62 fps < V 3xDC = 47.69 fps, Vc4xHWDP = 6.28 fps < V 4xHWDP = 26.82 fps, Vcjar = 6.28 fps < V jar = 26.82 fps, Vc16xHWDP = 6.76 fps < V 16xHWDP = 26.82 fps, then it is certain that the flow of mud in the circuit is turbulent so as to cause a cleaning effect on a fairly good circuit. In annulus obtained results VcaDP = 5.43 fps > V adp = 5.10 fps, VcaMWD Tools = 6.66 fps < Va MWD Tools = 10.38 fps, Vca3xDC = 6.10 fps < Va 3xDC = 8.05 fps, Vca 4xHWDP = 5.43 fps > Va 4xHWDP = 5.11 fps, Vcajar = 6.10 fps < Va jar = 8.05 fps, Vca16xHWDP = 5.43 fps > Va 16xHWDP = 5.11 fps, Looking at the results of calculations on annulus more average speed values then it can be ascertained that the flow of mud in annulus is turbulent.

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.
