The important factors in petroleum production are the nature of the reservoir rock surface and the <br /> <br /> interaction between oil and water in the reservoir. Both of these factors can affect microscopic efficiency <br /> <br /> in increasing oil recovery. In this study, microcellulose was tested as a potential agent to increase oil <br /> <br /> recovery. Microcellulose is used to alter the wettability of reservoir rocks and decrease interfacial tension <br /> <br /> between oil and water. Microcellulose is a micro cellulose with particle size ranging from 30 nm to 20&#956;m. <br /> <br /> This study aims to determine the effect of microcellulose on rock wettability and interfacial tension <br /> <br /> between oil and water. Microcellulose is obtained through the process of cellulose hydrolysis isolated <br /> <br /> from corncob. The results of hydrolysis reaction were characterized using FTIR to determine the <br /> <br /> functional group, Scanning Electron Microscope (SEM) to determine morphology. The particle size was <br /> <br /> determined using Particle Size Analyzer, changes in wettability were determined from contact angle <br /> <br /> measurements, and interfacial tension measurements. The results of the study obtained microcellulose as <br /> <br /> a result of hydrolysis reaction with an average diameter of 2.9 &#956;m and 14 &#956;m. The addition of <br /> <br /> microcellulose can changes rock wettabillity more hydrophylic. The higher concentration of <br /> <br /> microcellulose the rock surfaces become more hydrophylic. The experimental results show that the <br /> <br /> addition of microcellulose can decrease interfacial tension between oil and water 60.2%. According to <br /> <br /> these data microcellulose has the potential to be used as an economic and environmentally friendly oil <br /> <br /> recovery agent.
