Abstract
An insert valve configured to be installed, at least partially, in a safety valve in a borehole that includes a flow port disposed on an exterior of the insert valve, a poppet configured to control a fluid flow through the flow port, an upper piston rod, disposed uphole from the poppet, configured to move the poppet past at least part of the flow port, and a chamber, disposed downhole from the poppet that includes a chamber pressure, and a lower piston rod coupled to the poppet, where the lower piston rod is configured to exert a chamber piston force on the poppet.
Claims20
An insert valve configured to be installed, at least partially, in a safety valve in a borehole, comprising:
- a flow port disposed on an exterior of the insert valve;
- a poppet configured to control a fluid flow through the flow port;
- an upper piston rod, disposed uphole from the poppet, configured to move the poppet past at least part of the flow port;
- and
- a chamber, disposed downhole from the poppet, comprising:
- a chamber pressure;
- and
- a lower piston rod coupled to the poppet, wherein the lower piston rod is configured to exert a chamber piston force on the poppet.
An insert valve installed in a surrounding pressure, comprising:
- a poppet configured to control a fluid flow through a flow port;
- an upper piston rod coupled to the poppet and configured to move the poppet past at least part of the flow port;
- and
- a lower piston rod coupled to the poppet and configured to exert a chamber piston force on the poppet, wherein the lower piston rod traverses, at least partially, through a chamber.
