Latest Patents

One of Macune's latest patents is titled "Apparatus and method for resistivity well logging." This invention involves a well logging apparatus designed to determine formation resistivity at multiple depths of investigation. The system utilizes at least one transmitter antenna and two receiver antennas mounted in a logging tool housing along a common axis. The antennas are untuned coils of wire that emit electromagnetic energy at multiple frequencies into the formation. The receiver antennas detect reflected electromagnetic energy, allowing for the determination of formation resistivity using only phase differences in the reflected energy. This method minimizes false indications of invasion and corrects for varying dielectric constants, while also reducing the complexity of electronics and power requirements.

Another significant patent by Macune is the "Modified formation testing apparatus and method." This invention provides a means to obtain pristine formation or fluid samples using a work string designed for various downhole operations. The apparatus features an extendable element that extends against the formation wall to collect samples. When not in use, the extendable element is retracted within the work string, ensuring protection from damage during other operations.
