Experimental Studies of Steam Injection with Surfactant for Enhancing Heavy Oil Recovery after Waterflooding Objectives Steam injection with added surface active chemicals is an EOR process aimed at recovering residual oil after primary production. Researchers have shown that after waterflooding, the oil swept area can be increased by steam surfactant due to reduced steam override effect and reduced interfacial tension between oil and water in the formation. was tamped into the cell. A 3.0 wt% nonionic surfactant Triton X-100 was coinjected with the steam superheated to 200°C and pressured to 100 psig. For the vertical cell runs, steam injection rates were 5.5 ml/min and 2.5 ml/ min TX-100; for the horizontal cell runs, steam injection rates were 4.0 ml/min and 1.0 ml/min TX- 100 solution. The main objective of this research is to evaluate the effect on oil recovery of steam surfactant injection compared to that of pure steam injection. The experimental study will use a 1D displacement cell containing a sand mix of 20.5°API California oil. Approach Two experimental models were used: a vertical cylindrical cell 67 cm long x 7.4 cm ID (Fig. 1) and Fig. 2. Horizontal cell. CRISMAN INSTITUTE Fig. 1. Vertical cell. a horizontal cell 110.5 cm long x 3.5 cm ID (Fig. 2). The horizontal smaller diameter cell is less subject to channeling and is therefore more representative of one-dimensional steam injection process.
