Downhole shoe track tool, method, and system
A downhole shoe track tool, including a housing, a wiper plug landing profile disposed in the housing, a check valve disposed in the housing, and a surge suppressor configured to flow fluid axially, the suppressor disposed in the housing. A method for protecting a formation from hydraulic shock including applying pressure to the tool, the pressure resulting in surge, and suppressing the surge in the surge suppressor. A wellbore system, including a borehole in a subsurface formation, a string in the borehole, and a downhole shoe track tool disposed within or as a part of the string.
1 . A downhole shoe track tool, comprising:
a housing;
a wiper plug landing profile disposed in the housing;
a check valve disposed in the housing; and
a surge suppressor configured to flow fluid axially, the suppressor disposed in the housing; and
further including a baffle disposed within the suppressor.
2 . The tool as claimed in claim 1 , wherein the baffle includes an upstream surface that is disposed at an angle relative to an axial extent of the suppressor.
3 . The tool as claimed in claim 2 , wherein the angle is in a range of from about 30 degrees to about 90 degrees.
4 . The tool as claimed in claim 2 , wherein the angle is in a range of from about 45 degrees to about 60 degrees.
5 . The tool as claimed in claim 1 , wherein the baffle is frustoconical in shape.
6 . The tool as claimed in claim 3 , wherein the frustoconical shape points in the downstream direction.
7 . The tool as claimed in claim 1 , wherein the surge suppressor includes a plurality of baffles.
8 . The tool as claimed in claim 1 , wherein the baffle is orthogonally disposed in the housing.
9 . The tool as claimed in claim 8 , wherein the baffle includes through bores therein.
10 . The tool as claimed in claim 9 , wherein the through bores include at least one through bore with a first area and at least one other through bore with a different area.
11 . The tool as claimed in claim 8 , wherein the through bores are arranged in the baffle with relatively smaller area through bores centrally located and relatively larger area flow bores located radially outwardly of the relatively smaller through bores.
12 . The tool as claimed in claim 1 , wherein the suppressor is disposed upstream of the check valve.
13 . The tool as claimed in claim 1 , wherein the suppressor is disposed downstream of the check valve.
14 . The tool as claimed in claim 1 , wherein the check valve is a plurality of check valves.
15 . A method for protecting a formation from hydraulic shock comprising:
applying pressure to the tool as claimed in claim 1 , the pressure resulting in surge; and
suppressing the surge in the surge suppressor.
16 . The method as claimed in claim 15 , wherein the suppressing is by reflecting or redirecting portions of the pressure wave.
17 . The method as claimed in claim 16 , wherein the reflecting is angular relative to the axial extent of the suppressor.
18 . A borehole system, comprising:
a borehole in a subsurface formation;
a string in the borehole; and
a downhole shoe track tool as claimed in claim 1 disposed within or as a part of the string.
