Latest Patents

One of Dotson's latest patents is a method for determining consistent water relative permeability values. This method involves correcting water relative permeability values for a core sample by using dynamic displacement measurements. The process includes plotting a ratio of water rate output to calculated water relative permeability values against average water saturation. If a straight line segment exists in the plot corresponding to high average oil saturations, it is extrapolated to the end of the plotted data. If not, a tangent is plotted to produce a line that passes through the irreducible water saturation point, thus correcting the calculated values and eliminating distortions caused by end effects at the core sample.

Another significant patent is a method of improved oil recovery by simultaneous injection of water. This method focuses on recovering heavy oil from a subterranean, permeable, heavy oil-bearing reservoir. An oxygen-containing gas is injected into the lower portion of the reservoir to establish an in-situ combustion reaction, forming a combustion front near the injection well. Water is injected into the upper portion of the reservoir during combustion to prevent gas migration and to displace oil toward a production well. The efficiency of this process can be enhanced by adding thickening agents and water-soluble polymers.
