Dari hasil analisis ini dapat diketahui bahwa sumur “ASR-06” mengalami penurunan kompresibilitas fluida sehingga menyebabkan terjadinya penyimpangan pada pembacaaan kurva pressure derivative pada early time region. Hal ini dapat terjadi dikarenakan adanya fluida gas dan fluida liquid yang mengalir secara bersamaan. kedalam tubing dan mengakibatkan berkurangnya ruangan untuk fluida gas untuk mengalir didalam ruang tertutup. Fenomena changing wellbore storage akan mengakibatkan anomali pembacaan tekanan lubang sumur menjadi lebih tinggi daripada tekanan formasi pada waktu awal. Pada hasil pembacaan pressure build-up dengan metode pressure derivative didapatkan nilai skin dan permebabilitas yaitu 2.15 mD dan 4.75.

One of the common methods to cure loss circulation problem is using Lost Circulation Materials (LCM), but in the production zone, using LCM can damage the production zone. Therefore, underbalanced drilling is method that can be used to prevent loss circulation problems in production zone in geothermal well. One of the most common underbalanced drilling methods is aerated drilling or foam drilling. Aerated drilling was used to overcome the loss of circulation problem in production zone in K-01 Geothermal Well. Even though, the aerated drilling was already used, but the loss circulation problem was still occurred. The purpose of this research is to evaluate aerated drilling operation in K-01 Well using Guo Ghalambor’s Gas-Liquid Rate Window and make recommended gas-liquid rate for the next drilling operation. Gas-Liquid Rate Window is constructed using characteristic of the formation, drilling parameters, daily drilling report and also fluid injection characteristics that was used for aerated drilling operation in K-01 geothermal well. Using the constructed Gas-Liquid Rate Window, an evaluation is carried out for the drilling operation in K-01 geothermal well.  The gas-liquid rate parameters used in aerated drilling operations is evaluated while checking the loss circulation event from the mud logging data. After the evaluation of the aerated drilling is carried out in then a suggestion is made for the next drilling operation. Based on the evaluation, the combination of gas-liquid rates that was used on the 9.875\"hole section in K-01 Well was in the outside of the constructed GLRW therefore loss circulation problem occurred. The recommended gas-liquid rate combination from this research can be used to determine the gas-liquid rate combination to prevent loss circulation problems, wellbore damage and cutting transport problems.","PeriodicalId":435945,"journal":{"name":"PETRO:Jurnal Ilmiah Teknik Perminyakan","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124290518","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fathaddin","doi":"10.25105/PETRO.V9I4.8227","DOIUrl":"https://doi.org/10.25105/PETRO.V9I4.8227","url":null,"abstract":"Kebutuhan akan minyak bumi terus meningkat, namun disamping itu, produksi minyak bumi khusunya di sumur tua semakin menurun. Oleh karena itu, dikembangkanlah metode Enhanced Oil Recovery (EOR). Pada penelitian kali ini, metode EOR yang digunakan adalah injeksi kimia yang berupa injeksi surfaktan. Penggunaan surfaktan ini dimaksudkan untuk menurunkan tegangan antarmuka (interfacial tension) antara minyak dan air sehingga mampu membawa minyak keluar dari pori-pori batuan reservoir. Dalam penelitian ini, akan dibahas tentang percobaan injeksi surfaktan, dilihat dari pengaruh salinitas, jenis surfaktan, dan konsentrasi surfaktan pada batuan karbonat, serta pengaruhnya terhadap recovery factor. Percobaan ini menggunakan surfaktan jenis Alpha Olefin Sulphonate (AOS) dan Tween 20, di mana konsentrasi masing-masing jenis surfaktan adalah 0,1%; 0,25%; 0,5%; 0,75%; dan 1%. Salinitas brine water yang akan digunakan adalah sebesar 10.000 ppm, 15.000 ppm, 20.000 ppm, dan 25.000 ppm. Selanjutnya akan dilihat  seberapa besar kemampuan surfaktan dalam mengikat minyak dari pori-pori batuan, sehingga akan didapat hasil recovery factor atau berapa persentase  minyak yang terkandung dalam pori batuan yang dapat diproduksikan. Hasil dari penelitian ini akan diamati dari dua proses, yaitu proses imbibisi yang menggunakan Amott apparatus atau yang lebih dikenal dengan proses imbibisi (spontaneous imbibition) dan coreflooding. Dari percobaan yang telah dilakukan, pengaruh injeksi surfaktan pada batuan karbonat adalah hasil yang lebih optimal terdapat pada proses coreflooding dibandingkan dengan proses imbibisi, karena proses coreflooding menggunakan tenaga dorong dari luar, sehingga pendesakan minyak dengan surfaktan lebih merata dan optimal. Sementara dengan proses imbibisi pendesakan terjadi secara alami dengan mengandalkan gaya gravitasi.","PeriodicalId":435945,"journal":{"name":"PETRO:Jurnal Ilmiah Teknik Perminyakan","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114687835","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This uncertainty arises in conditions where rock type grouping is carried out in wells that do not have core sample data. Where we know that in the oil and gas field, not all wells in the field are subjected to rock sampling, either routine core analysis or special core analysis. From these problems, the authors feel the need to carry out this study to create a method for classifying reservoir rock types based on the physical properties of rocks that can be used in wells that do not have core sample data. The rock types in the wells that do not have core samples will be grouped based on the critical porosity value of the rock obtained from the vp value in the acoustic log data owned by these wells. By making an approach model through the critical porosity of rocks from wells that have core sample data, wells that only have acoustic log data can be grouped by using the critical porosity approach which is generated from the vp value of the acoustic log.","PeriodicalId":435945,"journal":{"name":"PETRO:Jurnal Ilmiah Teknik Perminyakan","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131586719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
