Latest Patents

Among David T. Oliver's most recent patents is a groundbreaking tool that uses nuclear magnetic resonance with external magnets. This invention provides methods and systems that allow for logging while drilling NMR measurements to be conducted with magnets strategically placed outside the drill collar. By integrating magnetically permeable members, he enhances control over the magnetic field gradient. The design allows for the placement of magnets either on or embedded within the drill collar, with an antenna arranged axially between them. Alternatively, a sleeve can be utilized, housing the magnets and antenna.

Another noteworthy patent by Oliver involves a system for measuring borehole geometry during drilling. This innovative method employs a nuclear magnetic resonance caliper, which consists of multiple coils coupled to the borehole assembly. Prior to drilling, the NMR caliper is calibrated for porosity and T2 values of the drilling mud. As drilling progresses, continuous scans of the borehole are performed, utilizing RF energy across varying frequencies to excite NMR signals at different depths. The resulting data allows for precise determination of borehole wall distances and porosity.
