Temperature Effects on Relative Permeabilities of Oil-Water Systems in Unconsolidated Sands for Short Core Samples
Abstract/Contents
- Abstract
- This project investigates the effect of temperature on the relative permeabilities of an oil-water system in unconsolidated sands. A number of researchers have attempted to explain these effects, however their findings are generally contradictory. Since there is an increasing interest in the use of thermal recovery methods it is essential to have a complete understanding of the principles governing these effects.During all runs the core was 100% saturated with oil and flooded with water. Runs were made at injection rates of 107 and 205 cc/hr. These rates were determined to be the rates at which data could be most accurately obtained given the constraints of the system. The temperature was varied between 24 and 149 degrees C (75 to 300 degrees F). All runs were terminated after 15 pore volumes of water was injected. During these runs the residual oil saturation decreased from 30.2% to 17.6% at 107 cc/hr and from 23.6% to 12.6% at 205 cc/hr for an increase of temperature from 24 to 149 degrees C. An original study of this report proved that relative Permeability values generated from data obtained from the same equipment may have been affected by inaccurate determination of the initial value of the pressure difference across the core. A procedure to correct this parameter was attempted and was determined that this procedure has a significant effect on the generated relative permeability values.As a result of this finding it was decided that further experimentation and data analysis is necessary to draw final conclusions about the effects of temperature on relative permeability. Future work is directed towards accurate laboratory measurements of the pressure difference across the core and a way to accurately determine the time of breakthrough.
