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.
