Title: The Innovative Contributions of David C Stromswold

Introduction

David C Stromswold is a notable inventor based in Addison, TX, who has made significant contributions to the field of subsurface formation analysis. With a total of five patents to his name, he has developed advanced methods and apparatuses that enhance the understanding of subsurface conditions.

Latest Patents

One of his latest patents is a method and apparatus for producing a porosity log of a subsurface. This innovative borehole logging tool utilizes a neutron detector to measure the die-away of nuclear radiation in the formation. By producing a model of the die-away using exponential terms, Stromswold equates the exponentially weighted moments of both the measurements and the model. This process allows for the determination of the formation decay constant and the epithermal neutron lifetime, ultimately producing a porosity log that is corrected for detector standoff.

Another significant patent involves a method for monitoring the hydraulic fracturing of a subsurface formation. In this method, a fracturing fluid or proppant containing a characteristic element emits delayed gamma rays when activated with neutrons. By comparing activation logs before and after fracturing, Stromswold's method measures the extent of travel of the fracturing fluid or deposition of the proppant within the fractured formation.
