Efek Jenis Rod dan Efisiensi Volumetrik pada Kinerja Pompa Angguk
No full textThe productivity of the beam pump is influenced by the sucker rod type, material quality, and volumetric efficiency. Therefore, the beam pump should be designed to reach an optimum condition. The type of rod affects ability of the beam pump to lift liquid up from an oil reservoir to the surface as well as the horse power requirement to operate the pump. On the other hand, the productivity of the pump is also influenced by the characteristics of the reservoir rock and fluid such asreservoir productivity, gas liquid ratio, salinity and Hydrogen Sulfide (H2S) which are contained in the reservoir fluid. The purpose of this study is to observe Effect of Rod Type and Volumetric Efficiency on the Performance of a beam pump at X-1 well and production estimation in the future. In this research, several rod types were tested to find their liquid lifting efficiency. Based on result analysis, the highest production as well as liquid lifting efficiency is attained by applying ROD 96/05.The liquid production rate and lifting efficiency of the rod type are 1132 bpd and 15.6. The application of better quality sucker rod material (API grade D) and less corrosive fluid conditions (salt water) will be able to produce fluid with a higher flow rate. Furthermore, the effect of the crank-pitman ratio on the production rate is not large. Lower volumetric efficiency pumps require higher pump speed and horsepower to produce fluid with the same flow rate as high volumetric efficiency pumps. However, pumps with low volumetric efficiency have lower peak loads (PPRL)

Get PDFOrganizational commitment in political parties is the most important element to support the achievement of political parties. Therefore, in maintaining the stability and achievement of political parties, organizational commitment to party members is important to be maintained and enhanced. This study aims to determine the increase in organizational commitment through career development training. Career development training consists of two aspects, namely career planning and career management. This career development training has seven sessions namely self assessment, Exploring opportunities, making decisions and goal settings, planning for the achievement of achievement goals and career management. Characteristics of the subjects of this study are party administrators who have a low and medium category of organizational commitment. The design used is the Pretest-Posttest Control Group. The hypothesis of this study is that there are differences in organizational commitment among party cadres between before and after career development training. Then in the second hypothesis, there is a difference in the level of posttest organizational commitment between the experimental group and the control group. While the data analysis uses the Mann Whitney test and the Wilcoxon test. Experimental results based on the Mann Whitney test found Z = -3,585 (p <0.01), meaning that there was a difference in posttest scores between the experimental group that was given training and the control group that was not given training, meaning the hypothesis (1) was accepted. Based on the Wilcoxon test it was found there was a difference between the organizational commitment score in the experimental group between before and after being given career development training with Z = -1836 (p <0.01) meaning the hypothesis (2) was accepted

Desain Komplesi Sumur Sour Gas; Sebuah Study Kasus
Get PDFAbstrakDesain komplesi harus mempertimbangkan beberapa parameter dari sumur, meliputi tekanan, temperatur, jenis fluida yang diproduksikan dan laju alir produksi sumur tersebut, dimana desain harus tahan terhadap beban yang dapat terjadi selama usia sumur. Jenis fluida yang dihasilkan berperan penting dalam pemilihan material, terutama untuk gas asam yang mengandung konsentrasi H2S dan CO2 yang tinggi. Analisa pemilihan material tubing, jenis packer dan aksesoris pelengkap dianggap perlu untuk memastikan bahwa material dan desain dapat menahan semua beban yang mungkin terjadi selama usia sumur.Setelah desain secara konseptual ditentukan, maka desain detail secara keteknikan dapat dilakukan. Pemilihan material dan desian komplesi sumur didasarkan pada kondisi sumuran dengan menggunakan beberapa metode, seperti stress analysis, triaxial stress analysis dan tubing movement analysis. Material yang terpilih kemudian diuji dengan kondisi masa produksi sumur dan selama tahap instalasi untuk melihat integritas sistem. Tubing 25CRW-80, Retrievable Packer dengan long locator seal bore complete with Perfluoro Elastomers, Tubing Retrievable SCSSV (Surface Controlled Sub-Surface Safety Valve) dan 25CR aksesoris komplesi dapat menahan semua kemungkinan beban selama siklus dan usia sumur.Kata kunci: gas asam, desain, komplesi, material. AbstractWell completion design is an important aspect in oil or gas well before the production phase. Completion design should consider some crucial parameters of the well including pressure, temperature, type of produced fluid and the flow rate of the well, where the design should last and overcome all of disturbance that migh occurs during well life cycle. The type of produced fluid plays an important roles in material selection, especially for sour gas that contains high concentration of H2S and CO2. Analyzing the tubing material selection, type of packer and completion accessories is considered necessary to ensure that the materials and design could withstand all the loads during well life. After conceptual completion design is define, then detailed engineering design is proceed. Material selection and completion design is based on the condition of the well by using several methods, such as stress analysis, triaxial stress analysis and tubing movement analysis. The selected materials then tested by the well production condition and during the installation phase to see the integration of the system. Tubing 25CRW-80, Retrievable Packer with long locator seal bore complete with Perfluoro Elastomers, Tubing Retrievable SCSSV (Surface Controlled Sub-Surface Safety Valve) and 25CR completion accessories could withstand all load possibilities for the well life cycle.Keywords: Sour Gas, Completion, Design, Material
ANALISA KARAKTERISTIK PENGUJIAN CO-FIRING BIOMASSA SAWDUST PADA PLTU TYPE PULVERIZED COAL BOILER SEBAGAI UPAYA BAURAN RENEWABLE ENERGY
Get PDFPelaksanaan pengujian karakteristik co-firing biomassa sawdust dilakukan pada pembangkit listrik jenis Pulverized Coal yang bertujuan untuk mengetahui pengaruh co-firing terhadap unjuk kerja parameter operasi seperti: temperature outlet mill (MOT), furnace exit gas temperature (FEGT), emisi dan keekonomian. Bahan bakar co-firing biomassa dicampurkan pada stockpile dengan komposisi 5% biomasa sawdust dan 95% batubara. Bahan bakar dimasukkan kedalam 6 bungker mill yang beroperasi. Pengambilan data pengujian dilakukan setelah proses stabilisasi beban minimal selama 1 jam dengan menjaga pembebanan tetap konstan pada maximum capacity rate, kemudian dilakukan pengambilan data uji pembakaran co-firing minimal selama 2 jam dengan interval pengambilan setiap 15 menit. Hasil pengujian menunjukan nilai FEGT ketika co-firing terjadi penurunan temperatur sebesar 4,2°C atau 0,4% lebih rendah dibandingkan saat coal firing. Temperatur outlet mill relative sama pada kedua kondisi saat cofiring maupun coal firing dengan arus motor mill pada tiap mill tidak seragam. Emisi gas NOx dan SO2 saat cofiring lebih rendah 2% sampai 3% dibandingkan saat coal firing. Pengujian ini juga mempengaruhi konsumsi bahan bakar spesifik saat cofiring lebih rendah 1,21% sebesar 0,629 kg/kWh dibandingkan saat coal firing sebesar 0,637 kg/kWh. Hasil perhitungan biaya produksi pada pengujian operasi 100% coal firing didapatkan harga 378,14 Rp/kWh, sedangkan pada operasi co-firing 5% sawdust didapatkan harga 369,73 Rp/kWh. Berdasarkan selisih biaya produksi, co-firing 5% sawdust menghemat biaya energy primer sebesar 8,41 Rp/kWh atau lebih rendah sebesar 2,22%
