Definitions

  • Production wells are used to produce fluid from reservoirs in the geological subsurface.
  • fluids in the form of oil and gas are produced through wells, as is routinely the case in the oil and gas industry.
  • the production fluid is typically received in the well from the subsurface reservoir due to the natural pressure conditions, and then flows out of the well inside a dedicated production tubing disposed in the well.
  • the flow of gas and liquids in a production well takes place as a result of pressure in the reservoir.
  • the naturally occurring pressure may be sufficient to lift the fluids to the surface.
  • an artificial pressure may be added to increase the flow, or create a flow if the naturally occurring pressure is not sufficient to lift the fluids to the surface.
  • the artificial pressure is also referred to as artificial lift.
  • An electric submersible pump is a downhole pump which can be used to create artificial lift.
  • a system of multiple EPS lifted wells may be used, wherein the wells are connected to a common manifold.
  • the production fluid from the well is then transported along pipelines to a downstream facility, for example a floating production platform (in the case of an offshore well) where the fluid may be processed further.
  • Additional booster pumps may be provided in the production system at the surface, for example on the seabed, to help pump the production fluid from the well along the pipeline to the downstream facility at a suitable rate.
  • the main problems with the current technology ESP are: a limited life time (0.5-1 .5 years) before they have to be changed; high cost of changing the ESP (need a drilling rig to change the pump); loss of production when the ESP is down; higher well cost due to down hole equipment (in addition to the ESP itself); high OPEX of the ESP pump; cost, weight and space of the topside equipment to control the pump (mainly VSD); down hole diluent may be required to reduce the viscosity of the fluid in the well. The diluent is expensive and uses some of the available surface process capacity
  • the invention provides a method and system as defined in the accompanying claims.
  • Fig.1 illustrates schematically a system
  • Fig.2 illustrates a method
  • the method described herein may be used as an artificial lift method for heavy oil reservoirs where gas-lift cannot be applied due to high viscosity of the reservoir oil.
  • the method described herein provides for a method of injecting a combination of water and gas into a well. This method may be used to create artificial lift. The water and gas may be injected simultaneously into the well.
  • the water and gas may be injected into the well through holes in the production tubing, optionally as deep as possible such that injection takes place close to a lower completion section.
  • the holes in the production tubing may be provided with valves to control the inflow of water and gas.
  • the water and gas may be transported down in the annular space between the tubing and the smallest casing.
  • the water and gas may be transported down in a single shared tubing which is provided inside or outside the production tubing.
  • the water and gas may be transported down in separate tubing inside or outside the production tubing, wherein a first tube is provided for the water and a second tubing for the gas.
  • water can be provided at any position upstream the gas injection.
  • Water can also be provided by extending the well or a well branch into an aquifer.
  • An advantage of adding or injecting gas to the produced reservoir fluid is to generate a fluid mixture in the tubing with low apparent density, when compared to reservoir fluid without gas. Consequently, by adding, injecting and/or mixing water and gas down hole in the well with the produced reservoir fluid, the fluid mixture in the tubing will have both low viscosity and low density, thereby combining the advantages of water and gas.
  • the amount of water and gas injected into the production tubing down hole can be regulated continuously to maximize the production of reservoir fluid.
  • the amount of water and gas injected into the well may be varied depending on the composition of the produced fluid, such as water cut and gas liquid ratio of the produced reservoir fluid. Addition of water with continuous flow conditions can be one solution to secure low apparent viscosity of the fluid in the production tubing.
  • the added water to reduce friction pressure loss may also be used in connection with transportation of heavy oil outside the well, such as in pipeline transportation of oil.
  • FIG 1 illustrates a specific implementation for SWAGL (simultaneous water and gas injection lift).
  • the gas and water are mixed above the sea bed and combined in a single tube (1 ).
  • the tube extends through the Christmas tree (2) into an annulus (3), which is provided outside the innermost tubular extending towards the bottom of the well.
  • the tube terminates at a valve (4) provided at an opening in the tubular.
  • the opening is provided below the water, below the seaf loor and below the cap rock.
  • Other alternatives are injection of water and gas in single or separate tubings inside or outside the production tubing, or controlled water production from the aquifer combined with conventional gas lift.
  • Figure 2 illustrates a method of combining gas and water (S1 ), and injecting the combination of water and gas into a well to create artificial lift (S2).
