Definitions

  • the invention relates to a method and system for monitoring well effluent plunger lift operations, wherein a plunger moves cyclically up and down through an underground wellbore to remove well effluent deposits therefrom.
  • US patent 6,634,426 discloses a method for optimizing plunger lift operations by "Counting Collars", wherein acoustic noise generated when the plunger passes an irregular tubing joint is monitored using an acoustic sensor in the wellhead assembly, which sensor also counts the number of joints passed by the plunger to determine the depth of the plunger in the well.
  • This known technique requires the presence of irregular tubing joints and cannot be used in wells equipped with coiled production tubing assemblies.
  • US patent application 20120323493 discloses the use of magnetic detectors in a wellhead assembly for detecting plunger arrival.
  • US patent application 20120193091 discloses the use of a sound-generating plunger to monitor plunger velocity in the wellbore.
  • a method for monitoring well effluent plunger lift operations wherein well effluent deposits are removed from a hydrocarbon fluid production well by a plunger that cyclically moves up and down through the wellbore comprising:
  • the method may further comprise optimizing the plunger lift operation and associated production of hydrocarbon fluid and well deposits in response to the acoustic signals recorded by the fiber optical Distributed Vibration Sensing (DVS)assembly relating to at least one of the vibration triggering events a)-j).
  • DVD Distributed Vibration Sensing
  • the hydrocarbon production well may be a natural gas production well and the fiber optical Distributed Vibration Sensing(DVS) assembly may comprise an optical fiber which extends along at least a substantial part of length of the wellbore, and is in acoustic contact with, an outer surface of a production tubing through which a multiphase well effluent mixture comprising natural gas and at least some liquid, viscous and/or solid well effluent components, such as water, condensates, wax, asphaltenes, precipitates and/or solid particles, are produced, and the plunger moves cyclically up and down through the production tubing to remove any well effluent deposits comprising the liquid, viscous and/or solid components from the interior of the production tubing.
  • a multiphase well effluent mixture comprising natural gas and at least some liquid, viscous and/or solid well effluent components, such as water, condensates, wax, asphaltenes, precipitates and/or solid particles
  • the production tubing comprises a permeable inflow region above a bottom of the well and the wellhead comprises a lubricator located above a well effluent outlet provided with a production choke and the plunger is cyclically moved up and down between the bottom of the well and the lubricator.
  • cyclic motion of the plunger may comprise the following phases:
  • the production of well effluents may be controlled by varying the opening of the production choke in response to information provided by the DVS assembly about the location and upward velocity of the plunger through the production tubing.
  • the fiber optical Distributed Vibration Sensing (DVS) assembly may be configured to monitor a location of a liquid-gas interface above a deposition of well effluents in the production tubing by monitoring noise associated by migration of the plunger and/or natural gas through the deposition and/or any temperature differences between the plunger, the natural gas and the deposition and the thus monitored location of the liquid-gas interface may be subsequently used as an input to a production choke control system to control the position of the production choke and the position and movement of the plunger within the production tubing, and/or to optimize the liquid unloading phase of the well, and/or a duration of the after-flow phase during which the plunger is arranged in a surface lubricator in the wellhead above the production choke and and/or a duration of the shut-in phase during which the production choke is closed and the plunger falls from the wellhead to a bottom of the well.
  • a production choke control system to control the position of the production choke and the position and movement of the plunger within the production tubing, and
  • a system for monitoring well effluent plunger lift operations wherein well effluent deposits are removed from a hydrocarbon fluid production well by a plunger that cyclically moves up and down through the wellbore comprising:
  • the system may further comprise means for optimizing the plunger lift operation and associated production of hydrocarbon fluid and well deposits in response to the vibrations recorded by the fiber optical Distributed Vibration Sensing (DVS)assembly relating to at least one of the vibration triggering events a)-j).
  • DVD Distributed Vibration Sensing
  • the plunger may comprise an acoustic source that is configured to transmit an acoustic noise that is detectable by the fiber optical Distributed Vibration Sensing (DVS) assembly.
  • DVD Fiber optical Distributed Vibration Sensing
  • the Distributed Vibration Sensing (DVS) assembly may be configured to monitor acoustic events with frequencies of less than 50 Hz, optionally frequencies of less than 20 Hz, in particular frequencies below 10 Hz.
  • Figures 1-4 show a hydrocarbon fluid production well that is cleaned by a plunger lift well cleaning operation wherein a plunger 1 is moved up and down through a production tubing 2 within the wellbore 3 to lift liquid and solid deposits 4 to hydrocarbon fluid processing facilities (not shown) at the earth surface 5.
  • the plunger 1 is located at the bottom 6 of the wellbore 3 below a perforated well effluent influx zone 7 in which the perforations 15 have been shot through the production tubing 2, and through the gravel pack 8, the well casing or liner 9 and the surrounding hydrocarbon bearing formation 10 to permit influx, as illustrated by arrows 11 of a multiphase mixture of well effluents comprising natural gas and solid and/or liquid components, such as water, condensates, wax, asphaltenes and/or other precipitates and/or formation particles, such as rock, sand and/or clay particles, flow into the production tubing 2.
  • natural gas and solid and/or liquid components such as water, condensates, wax, asphaltenes and/or other precipitates and/or formation particles, such as rock, sand and/or clay particles
  • At least a fraction of the solid and/or liquid components may be dragged by the flux of natural gas illustrated by arrows 11 to the wellhead 12 and at least another fraction of the solid and/or liquid components may accumulate in a gradually increasing pool 13 of well deposits through which natural gas bubbles 14 travel in upward direction as illustrated by arrows 11.
  • a fiber optical Distributed Vibration Sensing (DVS) cable 16 is bonded to the outer surface of the production tubing 2 and is connected to a DVS interrogation assembly 17, which is configured to monitor vibrations resulting from acoustic and/or thermal events within the wellbore 3, such as the noise generated by the flux of natural gas bubbles 14 through the pool 13 of well deposits.
  • DVS interrogation assembly 17 which is configured to monitor vibrations resulting from acoustic and/or thermal events within the wellbore 3, such as the noise generated by the flux of natural gas bubbles 14 through the pool 13 of well deposits.
  • the DVS interrogation assembly 17 indicates that the level of the pool 13 of well deposit reaches a level at which production of natural gas is inhibited then the production choke 31 may be fully opened so that the well effluents drag the plunger 1 to surface.
  • Figure 2 shows the well onloading phase during which the thus released plunger 1 is further pushed up, as illustrated by arrow 20, by the flux of well effluents 11 through the production tubing 2 and thereby also pushes the pool 13 of well deposits up towards the wellhead 12.
  • the plunger 1 may or may not be equipped with fins 21 that may not fully seal off the annular space between the plunger 1 and the inner surface of the production tubing 2, so that a residual fraction of the produced natural gas still migrates as gas bubbles 14 through the annular space and the pool of well deposits 13 above the plunger, thereby allowing the DVS interrogation assembly 17 to monitor the upward migration and size of the pool of well deposits 13 as it is pushed by the plunger 1 towards the wellhead 12.
  • the DVS interrogation assembly 17 is also configured to monitor acoustic events associated with the upward movement of the plunger 1 through the production tubing 2, such as the scratching of the fins 21 and/or other parts of the outer surface of the plunger 1 along the inner surface and/or tubing joints of the production tubing 2, and/or whistling noise generated by the residual fraction of natural gas flowing through any remaining gaps between the fins 21 and/or other parts of the outer surface of the plunger 1 and the inner surface of the production tubing 2.
  • Figure 3 shows the well during an afterflow phase during which the plunger 1 is located within a lubricator 30 in the wellhead assembly 12.
  • the DVS interrogation assembly 17 monitors the position and upward velocity of the plunger 1 and induces, if the upward velocity of the plunger is too high when it approaches the wellhead assembly 12, a gradual closing of the production choke 31 and/or bypass valve 32 at the wellhead outlet conduits 33 and 34, thereby reducing the flux of well effluents 35 and the associated upward velocity of the plunger 1.
  • the bypass valve 32 and a lubricator valve 36 are closed, so that the lubricator 30 is isolated from the wellbore 3 and may be opened to retrieve the plunger 1 from the well for maintenance, inspection or replacement wherein the plunger 1 may be cleaned, worn fins 21 may be replaced and/or a spring and/or bladder actuated plunger release mechanism may be re-activated.
  • the production choke 31 is closed and the lubricator valve 36 is opened to allow the plunger 1 to be lowered by gravity forces to the bottom 6 of the wellbore 3 as illustrated in Figure 4 .
  • noise 40 When the plunger 1 descends through the wellbore 3 noise 40 will be generated by friction between the fins 21 and/or other parts of the outer surface of the plunger 1 and the inner surface of the tubing 3 tubing joints and/or perforations 15. This noise 40 is monitored by the fiber optical DVS cable 16 and associated DVS interrogation assembly 17, so that the position and downward motion of the plunger 1 are accurately monitored. Once the DVS interrogation assembly 17 indicates that the plunger 1 reaches the bottom 6 of the wellbore 3 the production choke 31 or bypass valve 32 is opened so that well effluent production is re-started and the produced well effluents drag the plunger 1 to surface.
  • the plunger 1 may be equipped with an acoustic source, such as a whistle and/or battery powered microphone that transmits a noise 40 that can be accurately monitored by the fiber optical DVS cable 16 and associated DVS interrogation assembly 17.
  • an acoustic source such as a whistle and/or battery powered microphone that transmits a noise 40 that can be accurately monitored by the fiber optical DVS cable 16 and associated DVS interrogation assembly 17.
  • the DVS cable may be embedded in a cement annulus surrounding the well casing or liner 9 instead of an annular space between the production tubing 2 and well casing or liner 9.
