Abstract

One of the methods to achieve optimal conditions in increasing oil recovery through injecting polymers is by optimizing the parameters that influence the success of injecting polymers to provide information and be considered when determining new schemes for implementation in the future. Optimization to obtain the optimum value of the recovery factor and the best value of the parameters PV, injection rate, injection time, injection pressure, adsorption, residual resistance factor (RRF), and inaccessible pore volume (IPV) using a genetic algorithm with three training ratios and testing 70: 30, 80: 20 and 90: 10 using 1000 datasets. The best value obtained for each parameter is at a ratio of 90: 10, which is the best model with the lowest reference error value with RSME of 0.241104 and MAPE value of 19.1964 classified as good prediction with the value of each adsorption parameter 0.1737 (g/l), injection rate 703 (bpd), injection pressure 1816, IPV 0.2524, RRF 4.8319 and finally the optimum value for recovery factor is 53.9557.

Abstract

Masalah yang terjadi di lapangan minyak dan gas saat ini adalah penurunan produksi minyak dan gas. Kondisi ini dipengaruhi oleh keadaan reservoar yang sudah tua yang mengandung minyak berat sehingga sulit mengalir. Selain itu, factor reservoar yang sudah digenangi air, sehingga air lebih banyak diproduksi dibandingkan minyak. Penelitian sebelumnya dengan menggunakan polimer hydrolyzed polyacrylamides (HPAM) mendapat hasil yang kurang maksimal untuk reservoar klastik (seperti sandstone ataupun limestone clastic), dan untuk kondisi temperatur dan tekanan tinggi. Tujuan dari penelitian ini adalah untuk mengoptimalkan sweep efficiency pada proses enhanced oil recovery (EOR) dengan menginjeksikan polimer kationik ke dalam reservoar. Penelitian ini menggunakan metode pengujian laboratorium dengan melakukan pengujian karakterisasi, reologi dan pengujian core flooding. Hasil yang diperoleh dari pengujian ini adalah polimer kationik memiliki morfologi yang teratur seperti film, serta pada suhu 30˚C, 50˚C, dan 60˚C tidak terjadi penggumpalan. Adapun, nilai viskositas mengalami kenaikan seiring dengan peningkatan konsentrasi polimer. Polimer kationik dengan konsentrasi 3000 ppm memiliki nilai viskositas tertinggi yaitu 32,77 cP sehingga nilai konsentrat tersebut memberikan pengaruh yang kuat terhadap peningkatkan oil recovery. Namun, hasil uji reologi (salinitas, suhu, dan shear rate) tidak berpengaruh signifikan terhadap kinerja polimer. Nilai incremental recovery factor polimer kationik lebih signifikan dibandingkan polimer sintetik lainnya, yaitu 35,62% ROIP.

Abstract

RUA field is classified into heavy oil reservoir type due to the high viscosity value and low API degree . This causes the RUA field can not be produced conventionally. the solution of this problem is to apply steam or thermal injection into reservoir which could reduce the viscosity of the heavy oil (Bera & Babadagli, 2015). One of the best EOR methods that has been proven to overcome this issue is using CSS method (Suranto et al., 2020). During the production period, the CSS process can affect the viscosity of the oil by increasing the temperature of the oil in the reservoir. In one production well, cyclic work are applied periodically, its called repeated cyclic (J. J. Sheng, 2013). This is because time of reservoir temperature stays above the baseline temperature reservoir shortly. Even though the cyclic already done repeatedly, there is still a decrease of oil production, different peak reservoir temperatures, and found the possibility of pump damage after the cycle job which led to the need for analysis on these issues. The analysis was performed by looking at the historical production data, historical reservoir temperature data, and production pump work data in the RUA field. After a production history data that reprsentative analyzed, it was found that teh production after cyclic there is increasing, and there is also a decline from the previous cyclic production. Based on the results of the production analysis, it was found that 53.24% of the production wells in the RUA field were already in the ramp down stage and 46.75% were already in the ramp-up stage. Meanwhile, the average HET for regular cyclic jobs is 3-4 months and 5-6 months for long cyclic jobs. And from the pump work data, only 3 wells were damaged. This suggests that cyclic stimulation is completely safe to be performed in this field.

Abstract

Polymers are often used to increase oil recovery by improving sweeping efficiency. The screening was carried out as a first step in evaluating the test parameters of several polymers of the Hydrolyzed Polyacrylamide (HPAM) type in fluid and sandstone reservoir rocks. The test was carried out using a reservoir fluid classified as light oil (35°API) and at a reservoir temperature (60°C). The HPAM polymers used are A1, F1, F2, F3, and P1 polymers. The test parameters carried out on these 5 types of polymer (A1, F1, F2, F3 dan P1) include a compatibility test for formation water. The rheology polymer test includes concentration vs Tres, and shear rate vs viscosity which aims to determine the type of polymer solution being tested is a non-Newtonian or pseudoplastic fluid group. Thermal stability test of polymer for 60 days to determine the stability of the polymer solution and whether it is degraded or stable. Filtration testing with criteria FR value < 1.2, screen factor test, and adsorption testing using the static method with a standard limit of adsorption value < 400 µg/gr and polymer injectivity test. From these tests, scoring (range 0-100) was carried out to determine polymer candidates in polymer flooding testing. The F1 polymer candidate for the sandstone reservoir was obtained with a score of 82.25. From the scoring results, the selected F1 polymer candidate has a concentration value of 2000 ppm. For thermal degradation, the polymer F1 2000 ppm experienced degradation of 15.5%. The results of the F1 2000 ppm polymer static adsorption test were 54.8 µg/gr. With the RRF = 1 value indicating rock permeability after injection of polymer F1 2000 ppm, it tends not to experience plugging due to injection of polymer solution.

Abstract

Desa Batu Belah merupakan wilayah agraris dengan komoditas utama kelapa sawit yang sebagian besar dikelola oleh petani pemula. Permasalahan utama yang dihadapi mitra adalah rendahnya nilai tambah tandan buah segar (TBS) berukuran kecil, keterbatasan teknologi pasca-panen, ketergantungan pada pupuk kimia, serta lemahnya manajemen usaha dan pemasaran hasil pertanian. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan kapasitas petani pemula sawit melalui pemberdayaan berbasis teknologi tepat guna dan pendekatan partisipatif. Metode pelaksanaan meliputi sosialisasi, pembuatan dan penerapan alat pembrondol sawit, pelatihan produksi pupuk organik, serta pendampingan manajemen usaha dan pemasaran. Hasil kegiatan menunjukkan peningkatan pengetahuan dan keterampilan petani dalam pengelolaan buah muda sawit, tersedianya satu unit alat pembrondol sawit yang berfungsi, serta kemampuan masyarakat memproduksi pupuk organik secara mandiri. Program ini berkontribusi dalam menyelesaikan permasalahan pada bidang produksi, manajemen usaha, pemasaran, dan sosial kemasyarakatan, serta mendorong peningkatan pendapatan dan kemandirian ekonomi masyarakat Desa Batu Belah.
