Abstract
A system and method of use are disclosed that enable a simplified operational procedure of isolating portions of a well bore. Specifically, a self-venting setting tool is described, that in an embodiment, utilizes well bore fluid as the inflation fluid for a downhole packing device. Simply exposing the tool to a pressure greater than atmospheric pressure readies the system for the setting of downhole packing devices. Otherwise, a typical system may be required to undergo a complex venting procedure prior to deployment or be susceptible to failure due to gas regions within the wellbore prior to reaching a desired location for the subsequent wellbore isolation.
Claims20
A wireline bottom hole assembly for use within a wellbore that extends into a subterranean formation, comprising a self-venting setting tool;
- the self-venting setting tool including:
- a pump module having a pump, a pump intake port and a pump output;
- a fluid source module disposed below the pump and in fluid communication with the wellbore above the bottom hole assembly, having a ported housing and a first fluid volume;
- the pump intake port disposed to intake fluid from the fluid source module;
- an electric motor operable to power the pump;
- a vent passageway in fluid communication with the pump, having a vent passageway intake on an uphole side of the pump intake port and disposed to vent gas from the pump module to the wellbore above the pump;
- an output passageway extending from the pump output, through the fluid source module.
