Embodiment Construction

[0111] First refer to the attached figure 1 , shows a schematic diagram of a downhole tool 10 according to the present invention. In use, the downhole tool 10 is placed into a borehole (such as an oil and / or gas production well borehole B) as part of a tubular string S, the downhole tool 10 being configured to allow selective axial passage of fluids through the downhole tool 10 , while preventing the lateral passage of fluid, the downhole tool 10 is operable to move from a first closed configuration to a second open configuration in response to an activation event, such that fluid is diverted through the lateral flow passage to the downhole tool 10 and borehole B In the annular part A between.

[0112] like figure 1 As shown in , the downhole tool 10 is operatively associated with a downhole pump P, which in the illustrated embodiment is a progressive cavity pump having a pump stator PS and a pump rotor PR, and as will be described further below, the downhole tool 10 is con...

Abstract

A downhole tool (10) operably associated with a downhole pump (P) for use in artificial lift applications includes a body (12) having a throughbore (14) forming an axial flow path and a plurality of lateral ports (16) forming a lateral flow passage, a valve seat (18) for cooperating with a valve member (22), and a sleeve member (20). In use, the downhole tool (10) is placed into a borehole, such as an oil and / or gas production well borehole (B), as part of a tubular string (S), the downhole tool (10) being configured to allow fluid to pass downhole Selective axial passage of the tool (10), while preventing lateral passage of fluids, the downhole tool (10) is operable to move from a first closed configuration to a second open configuration in response to an activation event to move fluids passing laterally The fluid of the flow path is diverted into the annulus (A) between the downhole tool (10) and the borehole (B).

Description

technical field [0001] The present invention relates to a downhole tool and method. More particularly, but not exclusively, embodiments of the present invention relate to a downhole tool operably associated with a downhole pump for use in artificial lift applications. Background technique [0002] During the extraction of natural resources (which may include hydrocarbon fluids and / or water and / or gases) from subterranean reservoirs, there is often a pressure differential (known as hydrostatic head) between the reservoir and the Earth's surface, which must be overcome in order to mine fluid resources to the surface. In the hydrocarbon production industry, this process is often referred to as "artificial lift." [0003] Artificial lift can be achieved using a variety of means including the use of pumps such as progressive cavity pumps (PCP). PCPs are positive displacement pumps and, as such, there is physical contact between their constituent pressure inducing components. ...
