Abstract

This study evaluates the influence of surfactant concentration on oil recovery performance under high-temperature and high-salinity reservoir conditions in the volve field using numerical simulations. Several surfactant concentration scenarios were applied to analyze production response and recovery factor behavior. The result indicate that increasing surfactant concentration only slightly improves oil recovery, with recovery factor remaining within a narrow range from 19.82% to 19.93% across all scenarios. Limited performance is associated with thermal degradation, adsorption, salinity effects, and reduced interfacial tension efficiency under harsh reservoir conditions. This study is limited to numerical simulation and requires laboratory validation to confirm surfactant chemical behavior under actual reservoir conditions. Therefore, future research should prioritize laboratory evaluation of thermally stable surfactants before filed scale implementation.

Abstract

The thickening time and mechanical strength are vital in the performance of the drilling cement and are usually tested by API standards. The paper determines the role of duck eggshells' calcium chloride (CaCl2) as a natural accelerator on the cement slurry properties. CaCl2 was prepared by a regulating reaction between eggshell powder and 1M HCl and then was mixed with the Class G cement at the 1%, 2%, 3%, and 4% weight proportions. The experimental findings show that the most preferred performance is observed when the CaCl2 is 4 percent, which reduces thickening time to 128 minutes and increases compressive strength to 4,464.62 psi and shear bond strength to 370.28 psi. These results imply that using waste materials as the source of CaCl2 bio-based accelerators would be a viable source that would be environmentally viable in the optimization of drilling cements

Abstract

Information technology is inseparable in the development of education, technology can be used as a tool or media to realize the goals of learning. Information technology is also useful as a stimulation of learning so that students can construct their own knowledge through various activities such as: problem solving, reasoning, and communicating (doing math), as a vehicle for training critical and creative thinking. At MTs Negeri 7 Kuntu Village, the utilization of Information Technology has not been done optimally in the process of teaching and learning activities. Information Technology such as Microsoft Excel is needed as additional information on learning technology in the era of the Industrial Revolution 5.0 for teachers and students at MTs. Microsoft Excel can be used as an alternative solution for learning Flat Shapes Mathematics. The Community Service Team aims to conduct training in the use of Microsoft Excel to help students solve math problems in flat shapes. The implementation method in this community service goes through three stages, namely the preparation, implementation and evaluation stages. The results obtained from this community service show that students' understanding of the use of Microsoft Excel in solving phase D flat shapes problems has increased and also increased students' interest and motivation in learning math.

Abstract

The reduction in oil production rates due to the formation of calcium carbonate (CaCO₃) scale deposits on production pipes is a common problem in upstream oil and gas operations. This study aims to evaluate the effectiveness of acetic acid produced from pineapple peel fermentation, alone and in combination with hydrochloric acid (HCl), as an organic-based scale-removal agent, with EDTA-2Na used as a comparison via chelation. The research methods included acetic acid extraction via two-stage fermentation, characterization of functional groups by infrared spectroscopy (FTIR), and analysis of mineral scale composition by X-ray fluorescence (XRF). Scale testing was carried out using the weight-loss method with immersion times of 30, 60, and 90 minutes. FTIR results showed the presence of characteristic organic acid functional groups, while XRF results confirmed that the scale was dominated by calcium as the main component of CaCO₃. The test results showed that the mixture of acetic acid and HCl provided the highest effectiveness with a mass loss of 0.43 grams at 90 minutes, followed by pure acetic acid at 0.36 grams, while EDTA-2Na produced a reduction of 0.08 grams. These results indicate that biomass-based acetic acid has the potential to be a more environmentally friendly alternative for scale removal in oil and gas production piping systems.

Abstract

Penggunaan rutin pembersih rumah tangga sintetis dapat menimbulkan persoalan kesehatan dan lingkungan apabila produk dipilih, dicampur, atau dibuang tanpa pengetahuan yang memadai. Kegiatan pengabdian ini bertujuan mengenalkan praktik pembersihan yang lebih aman dan ramah lingkungan serta melatih peserta didik membuat pembersih alami dari bahan dapur yang mudah diperoleh. Kegiatan dilaksanakan di MTs Negeri 7 Kuntu, Kampar Kiri, Riau, pada 8 September 2023 melalui edukasi interaktif, demonstrasi, praktik terbimbing, aplikasi langsung pada permukaan bernoda, dan refleksi. Bahan yang digunakan meliputi cuka, soda kue, garam, sitrun, sabun cuci piring, dan kulit jeruk. Peserta didik mampu mengikuti tahapan pembuatan, menjelaskan fungsi dasar asam-basa bahan, menghasilkan campuran pembersih, serta mengaplikasikannya pada keramik kamar mandi dan peralatan memasak. Keaktifan bertanya dan keberhasilan menyelesaikan praktik menunjukkan bahwa pembelajaran kontekstual berbasis pengalaman mendukung kesadaran lingkungan dan keterampilan praktis. Kegiatan ini memperlihatkan bahwa bahan lokal sederhana dapat menjadi pintu masuk edukasi pembersih hijau di sekolah. Kegiatan lanjutan disarankan menggunakan instrumen prates-pascates, formula terstandar, label keselamatan, dan observasi tindak lanjut.
