Title: Measurement of imbibition rate at elevated temperatures

Abstract

The performance and success of a waterflooding project depend on how rapid the imbibition process is. Imbibition rate has also been suggested as a measure of wettability. In order to investigate the effect of temperature on imbibition rates and extent, equipment has been designed and built to measure the volume of oil produced vs. time for countercurrent, radial imbibition of water into a cylindrical sandstone core with a hole along its axis. The imbibition process occurs only through the surface area of the hole and the ejected oil is produced back into this hole. Measurements were performed using cores of Berea and Bandera sandstones having different absolute permeabilities. Measurements were made at room temperatures and at one and in some cases 2 elevated temperatures. Results show an increase in imbibition rate with temperature increase. This was accompanied by an increase in ultimate recovery up to 175/sup 0/F and a reverse in this trend at higher temperatures. It was found that the increase in imbibition rate at elevated temperatures was due to the combined effect of the decrease in the oil-water viscosity ratio, the decrease in water viscosity and the increase of the water-wetness of the sandstone samples.
