Abstract: A protective tubular is run downhole into a wellbore in a subterranean formation. A non-metallic tubular is disposed within the protective tubular. The non-metallic tubular includes an adapter. The adapter includes a spring-loaded latch, a ball seat, a shear pin, and a ball catcher. While intact, the shear pin holds a position of the non-metallic tubular relative to the protective tubular. A ball is used to shear the shear pin of the adapter, thereby allowing the non-metallic tubular to move relative to the protective tubular. Pressure is applied to the ball to move the non-metallic tubular relative to the protective tubular. The non-metallic tubular is coupled to the protective tubular using the spring-loaded latch of the adapter. Pressure is applied to the ball to shear the ball seat of the adapter. A fluid is flowed into the non-metallic tubular through an opening defined by the adapter.

Abstract: An imaging device included in an assembly located in a wellbore during drilling operations may include a cylindrical housing that extends along a central axis thereof. The imaging device may include at least one gradient coil configured to produce a unique magnetic field weaker than a main magnetic field. The at least one gradient coil may create a variable field that is increased or decreased by changing a direction of the unique magnetic field with respect to a direction of the main magnetic field to allow a specific part of a rock formation to be scanned by altering and adjusting the main magnetic field. The imaging device may include at least one radio frequency coil configured to transmit radio frequency waves into the rock formation. The imaging device may include at least one magnet disposed in the cylindrical housing that resonates against the unique magnetic field.

Abstract: A downhole investigation tool for a borehole is disclosed. The downhole investigation tool includes a number of ultrasonic probes configured to generate an ultrasonic image of a forward portion of the borehole ahead of the downhole investigation tool and a rear/side portion of the borehole behind or beside the downhole investigation tool, at least one magneto-vision probe configured to generate a magneto-vision image of the forward portion and the rear/side portion of the borehole, and a mechanical attachment configured to attach the downhole investigation tool to a wireline or a steel pipe in the borehole.

Abstract: A downhole fluid sampling system includes a tool body to attach to a tubing string, and multiple probe pads having a curved shape and disposed circumferentially about a section of the tool body in a helical gear pattern about a central longitudinal axis of the tool body. Each probe pad includes probes on an external surface of the respective probe pad, and each probe can contact and engage a wall of a wellbore and receive a flow of formation fluid from the wall of the wellbore. An outer surface of the tool body includes multiple channels disposed circumferentially about the section of the tool body and between the probe pads. The channels direct fluid flow along the tool body.

Abstract: Formation fluid sampled from within a wellbore is separated into gas and liquid fractions while downhole and in a wellbore. A separator vessel is used to isolate the gas and liquid fractions from one another. Baffles are arranged in a staggered formation within the separator vessel and in the path of the flow of the sampled formation fluid. Contact with the baffles perturbs the flow of sampled formation fluid, which promotes escape of the gas fraction from the fluid. The gas fraction is ported from an upper end of the sample vessel to a sample bottle for analysis. The liquid fraction collects in a lower end of the sample vessel, and is discharged into the wellbore.
