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

A method of cooling at least a portion of a downhole tool located within a drilled wellbore using a fluid pill configured to transfer heat away from a heat-generating segment of the downhole tool. The downhole tool may be a wireline logging tool. The fluid pill can comprise at least one fluid coolant and may include other additives that enable the fluid pill to transfer heat away from a heat-generating segment of the downhole tool even in the presence of one or more fluids present in the drilled wellbore. The fluid pill can be introduced into residual drilling mud in the wellbore, and the downhole tool may thereafter be operated with the heat-generating segment thereof in fluid contact with the fluid pill, whereby heat generated by the heat-generating segment is transferred away from the downhole tool and toward a wall of the wellbore by the fluid pill.

Using fluid pill for heat transfer downhole

Disclosed herein are methods and systems for capturing a large collection of downhole fluid samples and, more particularly, disclosed are methods and systems for using at least two hydraulic pressure lines to alternatingly actuate hydraulic valves disposed in an interlinked series to obtain any large collection of hydraulically actuated components to be energized in sequence. A large collection of downhole fluid samples may be defined as any number of downhole fluid samples wherein the number of downhole fluid samples is larger than the number of actuators.

Method and apparatus for downhole fluid microsample collection with staged hydraulic actuation

A well interval isolation device is disclosed. The wellbore isolation device may have a plurality of expandable elements that cooperate upon expansion downhole in a wellbore to create multiple isolated well intervals. At least two pairs of expandable elements that are spaced apart on a tool string are usable to create both a primary isolated well interval and at least one isolated guard interval on each of an uphole side and a downhole side of the primary isolated well interval. The isolated guard intervals function to further isolate the primary isolated well interval from surrounding well fluid, thereby allowing a difference between the pressure within the primary isolated well interval and the hydrostatic pressure of the well fluid (i.e., the differential pressure) to safely exceed the maximum differential pressure at which any of the individual expandable elements can operate while simultaneously maintaining isolation of the well intervals.
