A wellbore tractor is provided. The wellbore tractor includes a single hydraulic line and at least one valve disposed along the single hydraulic line. At least two pairs of drives hydraulically coupled with the single hydraulic line such that the single hydraulic line can control the drives to open and/or close. A valve can be disposed along the single hydraulic line between each pair of drives. By controlling the opening and/or closing of each valve, along with controlling the inflow or removal of fluid in the hydraulic line, each pair of drives can be individually controlled to maneuver the wellbore tractor.

Wellbore tractor with independent drives

A method and system for removing a filter cover. A system and method may comprise a downhole fluid sampling tool including a tool body; a flow port disposed on the tool body; a sample chamber disposed within the tool body and fluidly coupled to the flow port; a pump disposed within the tool body. In examples, the pump is configured to pump a fluid through the flow port into the sample chamber; a filter disposed on an inlet of the flow port, wherein the filter is configured to filter the fluid entering the flow port; and a removable filter cover configured to prevent fluid contact with the filter.

Protection of a wellbore tool using fluid medium dependent material

Formation testing apparatus including a downhole testing tool for subterranean formation testing within a borehole of a well, the tool including a downhole sampling device having: a test tool body having an outer surface; and assembly extendable out of and retractable into an opening in the outer surface. The assembly includes a seal pad at a first end of the formation probe sampling assembly, the seal pad operable to contact a formation wall of the borehole when the seal pad is extended past the outer surface to thereby define a seal space between the borehole and the seal pad. The seal pad includes at the first end includes a metal plate with a trough therein, the trough defining a closed track in the metal plate, the trough having dimensions to hold a portion of an inflatable elastomeric ring shaped to fit in the trough. Methods of assembly and testing are disclosed.

Downhole testing tool for subterranean formation testing using a fluid sampling probe assembly

A system includes a pipe string; a wireline cable run through the pipe string; and a downhole tool for formation testing, wherein the downhole tool comprises, an upper assembly, an impeller unit connected to a downhole end of the upper assembly, wherein the impeller unit comprises a first impeller coupled to a second impeller by a shaft, a first flowline having a first end that is open to the formation, a packer unit that isolates a portion of a borehole surrounding the first end of the first flowline from the rest of the borehole, and a tool string connected to the first flowline, wherein the tool string hydraulically connects the packing device to the upper assembly.

High flowrate formation tester

A formation tester consists of an upper assembly, an impeller unit, a straddle packer unit, and an inverted reservoir description tool string. The upper assembly seals off the wireline cable at the rig and connects the wireline cable to the formation tester. The impeller unit includes an upper turbine which converts hydraulic power from circulation of drilling mud into mechanical power. The mechanical power is used to drive a lower impeller which is capable of pumping formation fluids at high flow rates. The straddle packer unit isolates a portion of the formation tester which is open to the borehole to allow entry and exit of formation fluids through the formation tester. The inverted reservoir description tool string contains a combination of formation description modules which are inverted from traditional reservoir description tool modules to allow fluid flow paths to bypass electrical components.

Coring tools including a core tube assembly; a carrier chamber defined within the core tube assembly for storing one or more core samples drilled from a downhole formation having a wellbore fluid therein, wherein the wellbore fluid has a wellbore fluid density; a non-hydrocarbon, non-reactive heavy weight fluid ('HWF') present within the carrier chamber, the HWF exhibiting a HWF density of about 2 pounds per gallon greater than the wellbore fluid density; a pressure housing cover selectively rotatable between (1) an open position, where the one or more core samples are able to be inserted into the carrier chamber, and (2) a closed position, where the carrier chamber is sealed; and a cover activation mechanism coupled to the core tube assembly and operable to move the pressure housing cover between the closed position and the open position.
