Effects of temperature on the absolute permeability of consolidated sandstone
The effect of temperature on absolute permeability has been a point of disagreement in the petroleum literature for many years. Recent work at Stanford University has shown no dependence on temperature of the absolute permeability to water of unconsolidated sand cores. The objective of this report is to extend the investigation to consolidated sandstone by following similar experimental procedures and observing whether any temperature effects exist. Fontainebleau sandstone was chosen as the core sample because of its low porosity and relatively clay-free composition. These characteristics allow the nature of consolidated sandstone permeability to be studied, while minimizing the effects of extraneous factors. Such factors, often present in Berea and Boise sandstones, include interstitital clay swelling in the presence of distilled water. Properties of sandstone differ from those of unconsolidated sand. Consequently, the effects of throughput water volume and flow rate, in addition to temperature, are studied. Mechanical difficulties with parts of the experimental apparatus have prevented the development of a satisfactory conclusion based on results obtained thus far. Recommendations are provided for necessary modifications before further experiments are performed. When these changes are implemented, a final run can be made to complete the analysis. 19 references, 10 figures.
