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

Produced water from petroleum operations contains high levels of hydrocarbons, suspended solids, and dissolved contaminants that must be treated before discharge or reuse. This study aims to optimize biosorbents derived from candlenut and walnut shells through chemical activation using potassium hydroxide (KOH) for the purification of produced water. In addition, an Internet of Things (IoT)-based monitoring system was integrated to enable real-time assessment of water quality parameters. The biosorbents were characterized using Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy (SEM) to identify surface functional groups and morphological modifications. Experimental evaluations of turbidity, bulk density, and total dissolved solids (TDS) were conducted under various operating conditions. The activated biosorbents exhibited enhanced hydroxyl and carboxyl functional groups, as confirmed by FTIR, with an optimal bulk density of 0.76 g/cm³. Under optimum conditions (pH 7, contact time 90 min, adsorbent dosage 15 g/L), turbidity and TDS removals reached 80% and 75%, respectively. The IoT system successfully enabled real-time data acquisition and process monitoring, ensuring operational reliability. The maximum adsorption capacity based on the Langmuir model reached 33.8 mg/g for KOH-activated walnut and 31.2 mg/g for candlenut biosorbent. Overall, the chemically activated candlenut and walnut biosorbents demonstrated excellent adsorption capacity and potential for sustainable produced water treatment. This approach offers an environmentally friendly and cost-effective solution by utilizing local biomass waste integrated with modern IoT-based control technologies. Adsorption behavior was further evaluated using Langmuir/Freundlich isotherm and kinetic models.
