ANALISA PRESSURE BUILD-UP TEST METODE HORNER MENGGUNAKAN PENDEKATAN P2 SUMUR N LAPANGAN Q
Get PDFAbstrak
Pressure Build-Up test termasuk ke salah satu jenis dari pengujian sumur atas biasa disebut dengan well testing. Pressure builp-up ini secara prinsip sumur akan ditutup dalam jangka waktu tertentu dan selama sumur ditutup kegiatan produksi akan dihentikan atau tidak ada proses produksi yang dilakukan dalam jangka waktu tersebut. Tentunya akan ada akibat yang ditimbulkan karena penutupan sumur ini, yaitu adanya kenaikan tekanan. Kenaikan tekanan ini akan dicatat sebagai fungsi dari waktu. Dalam paper ini, well test yang diteliti adalah Pressure Build-Up dengan tujuan untuk mendapatkan parameter – parameter reservoir yangakan didapat dari pengolahan data. Metode yang digunakannya adalah metode Horner dengan pendekatan persamaan P2 untuk mengolah data – data yang telah ada dari hasil pengujian sumur untuk memperoleh parameter – parameter reservoir, seperti nilai permeabilitas (k), faktor skin (s), LP skin, dan efisiensi aliran (FE). Berdasarkan dari hsil pengujian dan pengolahan data, nilai permeabilitas yang didapatkan adalah 17,18 mD. Untuk nilai skinnya sebesar -7,62 yang menandakan bahwa formasi dari sumur tersebut telah terjadi perbaikan formasi yang mana biasanya terjadi setelah dilakukan acidizing atau hydraulic fracturing.

Abstract
The pressure build-up test is one of the types of top-well testing which is commonly known as well testing. This pressure build-up, in principle, the well will be closed for a certain period of time and as long as the well is closed, production activities will be stopped or no production process will be carried out within that period. Of course there will be consequences due to the closure of this well, namely an increase in pressure. This increase in pressure will be recorded as a function of time. In this paper, the testing of the wells studied is Pressure Build-Up with the aim of obtaining reservoir parameters that will be obtained from processing data. The method he uses is the Horner method with the P2 equation approach to process existing data from well testing results to obtain reservoir parameters, such as permeability (k), skin factor (s), ∆P skin, and flow efficiency (FE). Based on the results of testing and data processing, the permeability value obtained is 17.18 mD. For the skin value of -7.62 which indicates that the formation of the well has repaired the formation which usually occurs after acidizing or hydraulic fracturing.

Get PDFAbstrak
Kebutuhan dunia akan minyak bumi semakin meningkat, maka dari itu produksitivitas minyak harus semakin ditingkatkan. Pada dasarnya sumur minyak dapat mengalirkan fluida ke permukaan secara natural flow pada saat tekanan reservoir fluida yang terdapat dalam formasi lebih besar dibandingkan dengan tekanan hidrostatik fluida yang mengalir di dalam tubing, sehingga fluida dapat terangkat dengan sendirinya ke atas permukaan. Sucker rod pump sendiri adalah salah satu jenis pompa dalam metode artificial lift untuk dapat membantu meningkatkan produksi minyak yang terdapat dalam sumur formasi yang banyak digunakan dalam dunia migas. Penelitian ini membahas mengenai pengaruh dari nefisiensi penggunaan sucker rod pump terhadap peningkatan laju alir produksi yang berada pada sumur NF. Berdasarkan dari data yang telah ada, dan telah dilakukan perhitungan maka di dapatkan hasil yang diinginkan. Efisiensi sucker rod pump yang terdapat pada sumur NF sebesar 10.372% dengan kecepatan pompa sebesar 1.443 spm . Yang mana nilai standar yang diperlukan digunakannya bantuan metode artificial lift adalah sebesar 80% dari nilai laju alir maksimum yang terdapat pada sumur. Dari hasil perhitungan yang dilakukan penulis, laju alir maksimum dari sumur NF sebesar 337 BFPD. Setelah dilakukan perhitungan kecepatan pompa yang dipakai pada sumur tersebut sebesar 1.443 spm dinaikkan menjadi 12.471 spm

Abstract
The world\u27s need for petroleum is increasing, therefore oil production must be increased. oil wells can flow fluid to the surface in a natural flow when the fluid reservoir pressure contained in the formation is greater than the hydrostatic pressure of the fluid flowing in the tubing so that the fluid can be lifted above the surface by itself. The sucker rod pump itself is a type of pump in the artificial lift method to help increase oil production in formation wells which are widely used in the oil and gas world. This study discusses the effect of the inefficiency of using a suction rod pump on increasing production levels in the NF well. Based on existing data, and calculations that have been carried out, the desired results are obtained. The efficiency of the sucker rod pump found in the NF well is 10,372% with a pump speed of 1,443 spm. This is the standard value required to use the help of the artificial lift method which is 80% of the maximum flow value found in the well. From the results of calculations performed by the author, the maximum flow rate from the NF well is 337 BFPD. After calculating the pump speed used in the well of 1,443 spm, it was increased to 12,471 spm

Get PDFThe elderly population in Indonesia is increasing. Data shows that around 1 in 10 residents are elderly. The productive elderly (potential elderly) can still contribute to the country\u27s progress. Health problems are important to support in all aspects of the elderly. Urinary tract infections (UTI) attack people of all ages. It is known that UTIs in elderly people in Indonesia are increasing. Predisposing factors for UTI sufferers in the elderly include comorbid diseases such as diabetes mellitus, malnutrition, cognitive dysfunction, depression, functional status disorders, prostatitis, history of surgery and vaginal prolapse, and lack of water consumption. Some urinary tract infections (UTIs) can be prevented by recognizing the early signs and symptoms of the disease and practicing clean and healthy living. If it occurs, urinary tract infections cause distress, disrupt daily activities and can increase the number of hospital admissions. Knowledge of recognizing the specific symptoms and signs of urinary tract infections will determine early detection and early diagnosis of this disease. Therefore, community service activities are carried out for the elderly community through education and counseling to recognize the signs and symptoms of urinary tract infections as prevention so that they can improve the health status of the elderly community. Through this activity, it is also hoped that the elderly community will receive more attention to their health through promotive, preventive and curative actions and become potential elderly people
Penyuluhan tentang Risiko Swamedikasi yang Kurang Tepat pada Anggota LMK RW 012 di Sunter Agung
Get PDFPain in the oral cavity is divided into two types, which are odontogenic pain and non-odontogenic pain. Often, people have difficulty seeking appropriate help for the pain they feel in their oral cavity. The initial response people take to alleviate this pain is by using over-the-counter medications (self-medication). Clinicians frequently encounter individuals who come for treatment having consumed medications irrationally. The actions taken are self-medication without proper indications and incorrect dosages. The background of this community service activity (PkM) is the lack of knowledge among the residents of RW 012 Sunter Agung about the causes of pain in the oral cavity and the risks of inappropriate self-medication for oral pain. This PkM activity aims to help the community practice rational self-medication and to provide knowledge about oral cavity pain. The implementation was carried out offline on 31st january 2024 by giving lectures regarding the causes of oral cavity pain and the risks of inappropriate self-medication, followed by a question and answer session. The results showed that there is knowledge improvement based on the differences in results of pre and post tests carried out
