Selective well barrier bottom, system, and method
View Patent ↗A selective well barrier/bottom, including a housing, a slip disposed in the housing, a drive bar in contact with the slip, a biaser between the housing and the drive bar, a seal on the housing to radially seal with a tubular radially outwardly of the housing, and a flow bypass arrangement to facilitate flow past the seal. A borehole configuration to convert a hydraulically settable downhole tool to a mechanically settable downhole tool, the arrangement including a seal and a flow bypass arrangement configured to allow fluid flow to bypass the seal. A method for setting a tool in a borehole including fitting the selective well barrier/bottom to the tool, and setting the tool with one of applied hydraulic pressure against the seal or set down weight against the selective well barrier/bottom. A wellbore system, including a borehole in a subsurface formation, a selective well barrier/bottom, disposed within the borehole.
1 . A selective well barrier/bottom, comprising:
a housing;
a slip operably disposed in the housing;
a drive bar in operable contact with the slip;
a biaser disposed between the housing and the drive bar;
a seal disposed on the housing to radially seal with a tubular radially outwardly of the housing, wherein the seal is a swab element; and
a flow bypass arrangement disposed to facilitate flow past the seal.
2 . The selective well barrier/bottom as claimed in claim 1 , wherein the flow bypass flow arrangement includes a check valve.
3 . The selective well barrier/bottom as claimed in claim 1 , wherein the check valve is movable with the drive bar.
4 . The selective well barrier/bottom as claimed in claim 1 , wherein the flow bypass arrangement includes a flapper valve.
5 . The selective well barrier/bottom as claimed in claim 4 , wherein a flapper of the flapper valve is tethered to the drive bar.
6 . The selective well barrier/bottom as claimed in claim 1 , wherein the housing includes a seat and the drive bar includes a check valve.
7 . The selective well barrier/bottom as claimed in claim 6 , wherein the check valve comprises a poppet, a poppet spring, and a poppet body.
8 . The selective well barrier/bottom as claimed in claim 7 , wherein the poppet body further includes a flare that interacts with the drive bar to limit stroke of the poppet.
9 . The selective well barrier/bottom as claimed in claim 1 , wherein the flow bypass arrangement is configured to alleviate surge pressure when running into a borehole.
10 . The selective well barrier/bottom as claimed in claim 1 , wherein the flow bypass arrangement is configured to pass flow from uphole of the well barrier/bottom when anchored in a borehole.
11 . The selective well barrier/bottom as claimed in claim 1 , wherein the flow bypass arrangement is configured to pass flow while pulling out of a borehole.
12 . A method for setting a tool in a borehole comprising:
fitting the selective well barrier/bottom as claimed in claim 1 to the tool; and
setting the tool with one of applied hydraulic pressure against the seal or set down weight against the selective well barrier/bottom.
13 . A method for constructing a borehole system comprising:
running into the borehole system with a selective well barrier/bottom comprising:
a housing;
a slip operably disposed in the housing;
a drive bar in operable contact with the slip;
a biaser disposed between the housing and the drive bar;
seal disposed on the housing to radially seal with a tubular radially outwardly of the housing; and
a flow bypass arrangement disposed to facilitate flow past the seal;
actuating the selective well barrier/bottom with hydraulic pressure applied against the seal;
actuating another tool in the borehole by applying hydraulic pressure against the seal or setting weight down on the selective well barrier/bottom; and
conserving hydraulic fluid in the borehole annulus with the seal.
14 . The method as claimed in claim 13 , further comprising supplying a backup mechanical actuation stop for the another tool.
15 . A borehole system, comprising:
a borehole in a subsurface formation;
a selective well barrier/bottom as claimed in claim 1 , disposed within the borehole.
