Abstract

The purpose of this study is to investigate the effects of initial oil volume and equilibrium time on the swelling factor during swelling tests. These parameters have not been addressed thoroughly in previous studies. Most investigators used only their own initial oil volume and equilibrium time during their experiments. The present study is focused on investigating the effects of these parameters under various initial oil volumes and equilibrium times according to the design of experiments. The optimum initial oil volume and equilibrium time to yield maximum swelling factor are determined. The initial oil volume and equilibrium time are found to contribute a positive impact to the swelling factor. Based on the results, the maximum initial oil volume is 3.4 cc or 85% of the total cell volume while the optimum equilibrium time is 101 min. The increment of the initial oil volume of .5 cc or 12.5% to 3.4 cc or 85% increases the swelling factor to 6.7% while the increment of the equilibrium time from 30 to 101 min increases the swelling factor to 4.9%. The study also found that the response surface method is appropriate to produce the optimum parameters in order to get maximum swelling factor.
