Surfactant adsorption onto solid surfaces is problematic in some industrial processes, such as in surfactant flooding for enhanced oil recovery. In this work, it was hypothesized that the use of a surfactant delivery system could prevent surfactant adsorption onto solid surfaces. Therefore, the encapsulation of sodium dodecyl sulfate (SDS) into the hydrophobic core of β-cyclodextrin (β-CD) to generate a surfactant delivery system (SDS/ β-CD) was evaluated in this work. This complexation was characterized using optical and scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FT-IR). Dynamic adsorption evaluation was applied to determine the effectiveness of the complexation in inhibiting surfactant adsorption onto a variety of solid adsorbents including sand, and mixtures of sand-kaolin and sand-shale. Surfactant adsorption was also evaluated applying the quartz crystal microbalance technology (QCM-D). The formation and morphology of the complexation was confirmed by optical microscopy, SEM, and FT-IR. Dynamic adsorption tests demonstrated the effectiveness of the surfactant delivery approach in preventing the adsorption of surfactant (up to 74 % adsorption reduction). The QCM-D technology confirmed these observations. Several mechanisms were proposed to explain the inhibition of surfactant adsorption including steric hindrance, self-association of inclusion complexes, hydrophilicity increase, and disruption of hemimicelles formation.

A r t i c l e I n f o A b s t r a c t Keywords: enhanced oil recovery (EOR), aOlefin Sulfonates (AOS), sandstone, limestoneA surfactant study for enhanced oil recovery (EOR) and surfactant adsorption profile aOlefin Sulfonates (AOS) was performed. This study aims to determine the type of surfactant that can be used for the enhanced oil recovery (EOR) process and to know the surfactant adsorption profile. This research was divided into 2 stages, the first step was the screening of surfactant, the second stage was the adsorption of surfactant in sandstone and limestone rock. Screening of surfactants performed included a dilution test in which the surfactant is dissolved in aquadest. The compatibility test in which the surfactant was dissolved in water and its formation was observed for 3 days. Thermal stability test in which surfactants that pass compatibility were heated to 80°C for 8 weeks. Adsorption of surfactants was carried out in sandstone (silica sandstone) sand, bangka sand, poor sand and limestone. The rocks were immersed for 168 hours in a 0.6% surfactant solution of S24 (a-Olefin Sulfonates); 1.2%; 1.8%, filtered and then centrifuged and measured their absorbance by UV-Vis spectroscopy. AOS surfactant 0.6% in silica sand and 1. 0% surfactant AOS in unadsorbed poor sand, making it suitable for enhanced oil recovery (EOR) process. A b s t r a k Kata Kunci: enhanced oil recovery (EOR), aOlefin Sulfonates (AOS), sandstone, limestoneTelaah surfaktan untuk proses enhanced oil recovery (EOR) dan profil adsorpsi surfaktan a-Olefin Sulfonates (AOS) telah dilakukan. Penelitian ini bertujuan untuk mengetahui jenis surfaktan yang dapat digunakan untuk proses enhanced oil recovery (EOR) dan mengetahui profil adsorpsi surfaktan. Penelitian ini terbagi 2 tahap, yaitu tahap pertama adalah screening surfaktan, tahap kedua adalah adsorpsi surfaktan dalam batuan sandstone dan limestone. Screening surfaktan yang dilakukan, meliputi: uji pelarutan di mana surfaktan dilarutkan dalam akuades. Uji compatibility di mana surfaktan dilarutkan dalam air dan formasinya diamati selama 3 hari. Uji thermal stability di mana surfaktan yang lolos compatibility dipanaskan 80°C selama 8 minggu. Adsorpsi surfaktan dilakukan di dalam batuan sandstone (batu pasir silika), pasir bangka, pasir malang dan limestone (batu kapur). Batuan direndam selama 168 jam dalam larutan surfaktan S24 (a-Olefin Sulfonates) 0,6%; 1,2%; 1,8%, disaring kemudian disentrifuge dan diukur absorbansinya dengan spektroskopi UV-Vis. Surfaktan AOS 0,6% dalam batu pasir silika dan surfaktan AOS 1,8% dalam pasir malang tidak teradsorpsi, sehingga cocok untuk proses enhanced oil recovery (EOR).
