Definitions

  • a mobile chemical injection configuration including a driver, a fluid supply line connected to the driver, and a chemical injection valve fluidly connected to the supply line.
  • a method for treating a wellbore including running a configuration as in any prior embodiment, into a borehole, injecting chemical to a target location in the borehole.
  • a borehole system including a tubing string and a completion and a configuration as in any prior embodiment therewithin.
  • Figure 1 is a schematic cross section of a portion of a wellbore configured as disclosed herein;
  • Figure 2 is a perspective view of a supply line having both an electric line and a capillary line therein.
  • a mobile chemical injection configuration 10 is disclosed.
  • the configuration includes a driver 12, which may be a tractor, and a chemical injection valve 14 and a supply line 16.
  • the supply line 16 may comprise a capillary tube 18 alone, or an electric line 20 and a capillary tube 18. It is to be understood that one or more of each of the electric line and the capillary tube are contemplated in embodiments.
  • the supply line 16 may be configured as a wireline, slickline, coiled tubing, flat pack, etc. as desired (see Figure 2, for example).
  • Figure 2 illustrates one of the embodiments of the supply line 16 having both a capillary tube 18 and an electric line 20, such as a TEC (tubing encapsulated conductor).
  • TEC tubing encapsulated conductor
  • the configuration 10 is configured to be deployed through tubing 22 and may be deployed after completion or during completion of the wellbore. Moreover, the configuration 10 is configured to negotiate past an ESP 24 toward a downhole end of an upper completion 26 into a lower completion 28 and may in some iterations extend to a toe 30 of the wellbore 32, even in a highly deviated or horizontal well.
  • the configuration is positionable as stated due to the action of the driver 12 that is specifically constructed to drag a line (any of the lines noted above) to wherever an operator would like the line to go. It will be appreciated that there are many tractor devices available commercially including those that operate on electric power and those that operate on hydraulic power. Any of these devices may be employed as the driver 12 discussed herein. Where the driver 12 is hydraulic, the supply line 16 may drive the driver 12 with either a hydraulic fluid conveyed therethrough or may even be driven by the chemical fluid itself in some iterations.
  • Tractor devices are capable of fitting between an ESP 24 and a tubing string 22 such that the valve 14 and supply line 16 may be snaked past the ESP and into the lower completion 28.
  • rollers 13 may also be employed if desired. Rollers are known to the art and require no further description. This allows for chemical injection in the lower completion which has heretofore not been possible.
  • the chemical injection valve 14 may also use any of a number of commercially available valves for this purpose including poppet-type chemical injection valves.
  • the valve 14 is to be fluidly connected to the supply line 16 such that upon intent, fluids conveyed through the supply line 16 may be dispensed through the valve 14.
  • valves 14 are illustrated in Figure 1. This is not intended to be a limiting illustration but rather any number from 1 to whatever maximally practical number of valves 14 is contemplated. In such embodiments, the valves may also be optionally addressable so that any number of valves 14 or sequence of the valves 14 or duration may be actuated to dispense fluid as is desired. Addressable valves 14 may be electrically addressable, in which case they will also be connected to an electrical source, or wirelessly connected to a controller and if hydraulically addressable, the supply line 16 may be used to transmit appropriate hydraulic signals to the various valves 14.
  • Continuous or intermittent dispensing is contemplated herein.
  • one embodiment employs the driver 12 to draw the supply line 16 all the way to the toe 30 and then will continuously inject chemical to the well at that point, which chemical will be entrained in the production fluid and interact with all parts of the lower completion 28.
  • Methods for treating a wellbore with the configuration include as noted continuous or intermittent injection with addressable or nonaddressable valves.
  • Embodiment 1 A mobile chemical injection configuration including a driver, a fluid supply line connected to the driver, and a chemical injection valve fluidly connected to the supply line.
  • Embodiment 2 The configuration as in any prior embodiment, wherein the driver is a tractor.
  • Embodiment 3 The configuration as in any prior embodiment, wherein the driver is electrically powered.
  • Embodiment 4 The configuration as in any prior embodiment, wherein the driver is hydraulically powered.
  • Embodiment 5 The configuration as in any prior embodiment, wherein the fluid supply line is a capillary tube.
  • Embodiment 6 The configuration as in any prior embodiment, wherein the fluid supply line supplies hydraulic fluid for a hydraulically powered driver and chemical injection fluid to the chemical injection valve.
  • Embodiment 7 The configuration as in any prior embodiment, further including an electric line.
  • Embodiment 8 The configuration as in any prior embodiment, wherein the electric line and the fluid supply line are bound together.
  • Embodiment 9 The configuration as in any prior embodiment, wherein the electric line and the fluid supply line are disposed in a wireline.
  • Embodiment 10 The configuration as in any prior embodiment, wherein the electric line and the fluid supply line are disposed in a slickline.
  • Embodiment 11 The configuration as in any prior embodiment, wherein the chemical injection valve is a poppet-type chemical injection valve.
  • Embodiment 12 A method for treating a wellbore including running a configuration as in any prior embodiment, into a borehole, injecting chemical to a target location in the borehole.
  • Embodiment 13 The method as in any prior embodiment, wherein the running occurs through tubing.
  • Embodiment 14 The method as in any prior embodiment, wherein the running includes running past an electronic submersible pump.
  • Embodiment 15 The method as in any prior embodiment, wherein the running is into a lower completion.
  • Embodiment 16 The method as in any prior embodiment, wherein the running is to a toe of the borehole.
  • Embodiment 17 The method as in any prior embodiment, wherein the method includes powering the driver with hydraulic fluid to a target location and then injecting chemical to the target location.
  • Embodiment 18 The method as in any prior embodiment, wherein the chemical is also the hydraulic fluid.
  • Embodiment 19 The method as in any prior embodiment, wherein the injecting is continuous.
  • Embodiment 20 A borehole system including a tubing string and a completion and a configuration as in any prior embodiment therewithin.
