Frac ball dispensers as well systems and methods employing such are disclosed. Configurations for remotely moving the frac ball dispensers in the vicinity of an open wellhead as well as remotely activating and verifying the dispensement of frac balls from the dispensers into the open wellhead are specifically provided. Configurations of frac ball dispensers to control access to frac balls therein as well as the dispensement of frac balls therefrom are also provided.

Frac ball dispenser

Downhole tool fluid flow control apparatus including a first fluid valve between a first portion of a first flowline and a second portion of a second flowline. The first and second flowlines are adjacent each other. A second fluid valve is between a second portion of the first flowline and a first portion of the second flowline. The first and second fluid valves are controllable to cause fluid flow between the first portion of the first flowline and the second portion of the second flowline or between the first portion of the second flowline and the second portion of the first flowline.

Fluid control modules for use with downhole tools

An apparatus for testing a subterranean formation penetrated by a wellbore, comprising a tool having a sample flow line an inlet disposed with the tool and configured to establish fluid communication between the formation and the sample flow line to draw a fluid sample into the sample flow line, and an active filter positioned in the sample flow line and providing a filter flow route and a bypass flow route in the sample flow line.

Downhole fluid filter

An apparatus for testing a subterranean formation penetrated by a wellbore is disclosed. The apparatus has a tool with a sample flow line an inlet disposed with the tool and configured to establish fluid communication between the formation and the sample flow line to draw a fluid sample into the sample flow line. An active filter is positionable in the sample flow line and provides a filter flow route and a bypass flow route in the sample flow line.

A cable release apparatus includes a housing and latch mounted at one end of the housing. The latch has a central opening and a plurality of projecting members extending into the housing. A releasable connector is mounted inside the housing. An actuator has one end disposed in the central opening in the latch and another end in contact with the releasable connector. The actuator is movable between a first position prior to activation of the releaseable connector and a second position wherein the releasable connector is activated. Prior to activation of the releasable connector, the latch is held in place by an interference fit between the projecting members and the housing. When the releasable connector is activated, the projecting members are deflected by applying tension to the latch, thereby releasing the latch from the housing.
