Abstract

Smart waterflooding is a widely discussed topic for oil recovery improvement, with the main mechanism believed to be wettability alteration. However, the exact phenomena behind this effect are still being debated. This systematic literature review (SLR) utilized the Scopus database to analyze and assess studies on the interfacial tension (IFT) and zeta potential (ZP) concepts and their impact on smart waterflooding between 2017 and 2021. The review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology. The review found inconsistencies in the literature, with some studies suggesting that the reduction of IFT from smart waterflooding was not the reason for oil recovery improvement. Further evidence on the alteration of surface charge through ZP analysis is needed, and gaps are present in the area of simulation approach. The study suggests that improvements in model development and experimental setup design are necessary for future studies to obtain comprehensive conclusions. In summary, this SLR provides a critical overview of the recent understanding of the impact of IFT and ZP on smart waterflooding and highlights areas for further research, including a potential model that incorporates each mechanism with the ultimate oil recovery.

Abstract

Enhanced Oil Recovery (EOR) is known to effectively improve oil recovery by producing the residual oil saturation in a reservoir. Many chemicals for injected fluid in EOR are synthetic and harmful to the environment. Aims: This study aims to characterize a newly developed green solution consisting of Sodium Lignosulfonate (SLS) and a Low Transition Temperature Mixture (LTTM) for injection agent. Methodology and Results: The concentration of surfactant was defined using weight percentage, which was calculated from the portion of the total weight of LTTM. The characterization was approached by analyzing the behavior of the green solution based on the power law analysis of the rheological measurement. The analyses of  value, viscosity, shear rate, and shear stress were carried out. Increasing in viscosity was caused by the additional molecular mass of sucrose in the solution. This study found that the SLS concentration and LTTM ratio affects the rheological behavior of the green solution. Conclusion, significance, and impact study: According to the results, adding the SLS concentration increases the probability of the green solution becoming an EOR agent by showing shear-thinning behavior. Further studies are required to ensure the feasibility of the green solution during the injection period and the propagation in the reservoir.

Abstract

Pengolahan limbah organik menjadi salah satu permasalahan yang ditemukan di lingkungan sebuah Pondok Pesantren di Ciampea, Kabupaten Bogor. Pemilahan jenis limbah juga belum dilakukan, sehingga dibutuhkan edukasi pengolahan dan pelatihan pemanfaatan limbah organik. Kegiatan dimulai dari observasi lapangan untuk mengetahui kebutuhan dan permasalahan mitra, dilanjutkan dengan penyuluhan terkait penggunaan produk rumah tangga yang kerap kali menggunakan bahan kimia dan bahayanya bagi kesehatan dan lingkungan, penyuluhan terkait eco-enzyme sebagai upaya pengolahan limbah organik yang bermanfaat, dan pelatihan pembuatan eco-enzyme sebagai produk serbaguna dari limbah organik yang ramah lingkungan. Bahan dasar utama eco-enzyme berasal dari kulit buah yang rutin dikonsumsi, dengan tambahan gula jawa dan air. Baik santri maupun pengurus pondok pesantren sangat antusias dalam mengikuti kegiatan pengabdian kepada masyarakat ini. Para peserta pelatihan berkomitmen untuk melanjutkan proses produksi eco-enzyme dan memanfaatkan eco-enzyme dalam kegiatan sehari-hari sebagai bentuk kepedulian terhadap lingkungan serta penghematan biaya belanja rumah tangga pondok pesantren. Di samping itu, mitra juga masih membutuhkan pelatihan lanjutan seperti pemurnian air untuk kebutuhan sehari-hari.
