  • Publication number: 20260117647
    Abstract: A gap sub for wellbore fluids comprises an electrical isolation structure to electrically isolate two metallic ends of the gap sub and a housing mounted outside of the gap sub. The housing accommodates an “external gap” and a toolstring for acquiring in-situ measurements of wellbore and near-wellbore conditions and transmitting the measurements to surface using EM telemetry. The gap sub comprises an antenna rod connected to the “external gap”, the antenna rod straddling the electrical isolation structure in the gap sub to be electrically isolated from one metallic end of the gap sub and electrically coupled to the other metallic end of the gap sub.

  • Patent number: 11280189
    Abstract: A suspended fluid sampling and monitoring system includes a BOP, the BOP attached to a wellhead. The BOP is positioned above a wellbore. The suspended fluid sampling and monitoring system further includes a TEC, the TEC connected to a sensor package. The TEC and sensor package extend through the BOP into the wellbore. The suspended fluid sampling and monitoring system also includes a fluid sample line, the fluid sample line extending through the BOP into the wellbore. The suspended fluid sampling and monitoring system also includes a fluid sample intake and filtration device, the fluid sample intake and filtration device mechanically coupled to the fluid sample line within the wellbore.
