Spinning Drop IFT Measurement
Read moreThe designed Spinning Drop device (SD-ES10) is able to measure ultralow interfacial tension down to 10-5-5 mN/m. Ultra-low interfacial tension is utilized by special types of chemicals results in high oil recovery through IFT reduction and wettability alteration. These results help operators to develop and optimize emulsions and micro-emulsions.

HP-HT Pendant Drop IFT Measurement
Read moreThe pendant Drop Interfacial Tension system measures interfacial tension between liquid-gas and liquid-liquid interfaces using the pendant drop method as well as the contact angle between the liquid and solid interfaces at reservoir pressure and temperature of 400 bar and 100°C, respectively. This device utilizes two different manual pumps for the independent discharge of bulk fluid and drops fluid into the visual cell equipped with sapphire sight glasses. The device is also equipped with online image processing software that captures and analyses the images. The visual cell has external heaters placed inside the body of the cell to achieve homogenous heating.

Pendant Drop Contact Angle and IFT Measurement
Read moreDrop shape analysis (pendant drop method) is a convenient way to measure surface tension. In this method, video images of pendant drops are digitized to determine the interface loci, then measuring the IFT through the solution of the Young-Laplace equation. Wettability of the reservoir rock and interfacial tensions between the reservoir fluids play the most important role in the efficiency of oil recovery.

General Core Flooding
Read moreThe CF evaluates and optimizes oil recovery, based on different injection protocols and fluid, such as miscible and immiscible gas injection, surfactant injection, polymer injection and etc. This device tolerates a maximum pressure and temperature of 400 bar and 100 °C respectively, under unsteady state conditions at confining pressures up to 400 bar. One of the transfer vessels is a miniature type that can be used for rinsing the lines by filling them with toluene or other solvents. (E20: in addition, this miniature transfer vessel can be used for chemical or microbial flooding which the injected slug is small).

Sand Pack Core Flooding
Read moreThe sand pack system provides an alternative porous medium to perform EOR studies at reservoir conditions in terms of temperature and pressure. The sand pack is a tube, filled with calibrated sand with known grain geometry. This versatile device permits various EOR tests including water flooding, polymer injection, miscible and immiscible gas flooding. The sand pack system is an essential device for Petroleum Engineering laboratories as it does not require reservoir rock sample procurement & preparation.
