Definitions

  • Running coiled tubing (CT) in open water from a vessel, and then possibly directly through a subsea tree, as well as running CT by utilizing an injector on a vessel and an injector on the subsea tree/wellhead typically comprises concerns with maintenance of tension between vessel injector and subsea injector and/or reliance of passive heave control for the vessel injector.
  • a direct hydraulic control system e.g. a vessel to subsea assist jack, is impractical as the whip effect stress wave travels at near the speed of sound in the coiled tubing steel (damped by the surrounding water) whereas the transmission of a hydraulic pressure change command travels at the speed of sound in the hydraulic fluid. The former is approximately four times faster than the later.
  • Fig. l is a block diagram of an exemplary open water coiled tubing control system.
  • open water coiled tubing control system 1 comprises reel 20 configured to accept and spool/unspool coiled tubing string 100; one or more surface injectors 30 operatively in fluid communication with coiled tubing string 100; one or more reel tensioners 10 configured to control arch 110 formed by coiled tubing string 100 where control arch 110 is disposed in-between reel 20 and surface injector 30; and one or more controllers 40 configured to control reel tensioner 10 and allow movement of coiled tubing string 100 and surface injector 30 relative to each other without adding additional fatigue life consumption due to vessel heave.
  • Open water coiled tubing control system 1 typically uses surface injector motion to move coiled tubing string 100 into/out of the water.
  • coiled tubing string 100 is disposed about an outer surface of reel 20 but other embodiments are contemplated such as being disposed within or partially within reel 20.
  • Surface injector 30 may be mounted on heave compensator 32.
  • controller 40 is disposed intermediate reel 20 and surface injector
  • open water coiled tubing control system 1 further comprises subsea assist jack 50 to move coiled tubing string 100 into/out of subsea well 200.
  • open water coiled tubing control system 1 comprises a predetermined set of sensors (generally referred to but not specifically shown in the figure as callout “60”), which may be integrated into other components or separate.
  • the predetermined set of sensors 60 are operatively in communication with controller 40 and comprises one or more surface injector load sensors 61 configured to detect and provide data related to a load at surface injector 30; one or more coiled tubing string movement sensors 62 configured to detect and provide data related to movement of coiled tubing string 100 in reel tensioner 10 where the data comprise speed of movement; one or more surface injector movement sensors 63 configured to detect and provide data related to movement of surface injector 30; and one or more vessel movement sensors 64 configured to detect and provide data related to movement of vessel 210 where the data comprise active heave data and/or passive heave data.
  • the predetermined set of sensors 60 typically also comprise one or more subsea assist jack load sensors 65 configured to detect and provide data related to a load at subsea assist jack 50 and one or more subsea assist jack movement sensors 66 configured to detect and provide data related to movement of subsea assist jack 50.
  • open water coiled tubing control system 1 is deployed such as via vessel 210 which may also used to support surface injector 30.
  • Open water coiled tubing control system 1 receives information related to a load at surface injector 30 and, if present, at subsea assist jack 50; information on movement of coiled tubing string 100 in reel tensioner 10, surface injector 30, and, if present, subsea assist jack 50; and information on movement of vessel 210 or a compensation system such as heave compensator 32 used to support surface injector 30, e.g. either active or passive heave.
  • Open water coiled tubing control system 1 resolves all or a predetermined part of the information so received, e.g. by controller 40, to effect movement of coiled tubing string 100 into and/or out from subsea well 200 at a predetermined desired speed to achieve an outcome by having one or more commands issued to reel tensioners 10 by a single input from an operator. Typically, this is accomplished by an operator using controller 40 to issue one or more commands to reel 20, surface injectors 30, and reel tensioners 10 substantially simultaneously.
  • part of the resolved solution is to maintain coiled tubing string 100 at a predetermined tension in-between surface injector 30 and subsea assist jack 50.
  • controller 40 uses the information it receives from sensors 60 and determines a continuous movement rate of surface injector 30 versus an interrupted rate of subsea assist jack 50.
  • subsea assist jack 50 can be remotely disengaged from gripping coiled tubing string 100 when the force supplied by subsea assist jack 50 is no longer required to move coiled tubing string 100 into or out of subsea well 200. This can be accomplished by traditional means and/or by an instruction provided to controller 40 from a remote location or the like.
  • Open water coiled tubing control system 1 typically needs to have limited hysteresis to avoid a “whip effect” caused in part by an induced vessel movement resulting from wave action. Knowledge of the “whip effect” and the speed of translation on the stress wave through coiled tubing string 100 allows a determination of required system performance and operating limits of open water coiled tubing control system 1 versus the “sea state.”
