Definitions

  • the field of the invention is subsurface equipment that responds to hydraulic control from the surface and more particularly when that equipment is coupled with an electric subsea tree.
  • Downhole equipment such as subsurface safety valves (SSV) is typically controlled by a hydraulic control line that runs from a surface hydraulic power supply to the SSV housing.
  • SSV subsurface safety valves
  • Application of pressure holds the valve open and removal or loss of applied pressure generally results in the valve going closed.
  • a tree is installed subsea at the mud line. The tree is connected to surface located hydraulic controls through a hydraulic umbilical so that pressure can be developed in the hydraulic system at the surface can be transmitted to the downhole equipment.
  • the present invention improves this situation by providing a module at the tree that receives power and signal input from the umbilical and generates hydraulic pressure at the subsea tree for use by an SSV or other downhole hydraulically operated equipment.
  • the downhole component such as the SSV can be constructed to receive electrical power and signal input from the tree and the hydraulic lines along the tubing can be eliminated in favor of local generation of hydraulic pressure at the housing of the downhole tool such as the SSV.
  • the SSV can be reconfigured to open and close using an onboard electrically driven motor so that the hydraulic operating system can be replaced totally.
  • An all electric subsea tree can be coupled with a hydraulic pressure unit that is fed off electrical and control lines that are in the umbilical from the surface. In that way hydraulic lines do not need to be separately run from the surface to the tree.
  • hydraulic pressure can be generated at a downhole tool using power and control lines running from the tree to the downhole equipment.
  • the downhole equipment can be run by electric motor located downhole adjacent the downhole equipment and powered and controlled by lines running from the tree to the downhole location.
  • FIG. 1 is a schematic of a subsea tree with a locally mounted hydraulic pressure generating unit for the safety valve downhole.
  • FIG. 1 is a schematic representation that will be used to describe alternative design options.
  • the variations revolve around an electric subsea tree 10 that is disposed near the mud line 12 .
  • the wellbore 14 has a tubing string 16 in it and a subsurface safety valve (SSV) 18 mounted in the tubing string 16 .
  • SSV subsurface safety valve
  • a hydraulic pressure generating module 20 in one embodiment is mounted adjacent the tree 10 .
  • a power line 22 and a control line 24 extend from a control module 26 that is a part of the subsea tree 10 .
  • the umbilical 28 runs to surface at the waterline and provides power and control signals from the surface such as from a platform or a vessel (not shown).
  • Module 20 has an onboard controller 30 to power motor 32 which runs pump 34 .
  • a low pressure switch 36 set above the minimum pressure required to hold SSV 18 open is there to sound an alarm if the pressure declines below a preset value.
  • a high pressure switch 38 alarms if the operating pressure exceeds a predetermined maximum.
  • a pressure compensated reservoir 40 is provided as well as a multi-position valve 42 to direct pressure back to the reservoir 40 in the position shown in FIG. 1 or alternatively out line 44 through a wet connector 46 which is a quick connection that can be automatically connected when the module 20 is placed on the tree 10 or by a remotely operated vehicle (ROV) not shown.
  • Line 44 is a hydraulic line down to the SSV 18 that runs along string 16 in the known manner.
  • a pressure transmitter 48 can be connected to the pump 34 discharge t transmit the operating pressure to the surface on a real time basis.
  • the system can be closed or it can discharge hydraulic fluid when stroking the valve 18 . If the system is not closed it can be periodically replenished by an ROV or by a line run to the reservoir 40 .
  • a closed system that retains hydraulic fluid is preferred.
  • module 20 can be integrated into SSV 18 or along the string 16 near it so that lines 22 and 24 can continue to run into the wellbore 14 to a now relocated module 20 that is now in the wellbore close to or integrated with the housing of the SSV 18 .
  • hydraulic lines don't need to be run the length of string 16 while allowing the continued use of currently available hydraulically operated SSVs such as 18 .
  • the design of the SSV 18 can be reconfigured so that it needs no hydraulic power at all. Instead lines 22 and 24 run down the string 16 to a locally mounted electric motor M that directly or indirectly powers a flapper or other closure device in the SSV 18 . In this alternative, hydraulic pressure and a control system for it would not be needed. On the other hand, the currently available hydraulically operated valves could not be used and instead a different SSV design would be required for power and control input that would be all electrical.
