Definitions

  • the present invention relates to a system and method for recompletion of old wells. More specifically the invention relates to a system and a method as disclosed in the preamble of claim 1 and 7 , respectively.
  • a plurality of autonomous valves or flow control devices are substantially as those described in WO 2008/0048745 A1, belonging to the applicant of the present application.
  • WO-A-9208875 describes a horizontal production pipe comprising a plurality of production sections connected by mixing chambers having a larger internal diameter than the production sections.
  • the production sections comprise an external slotted liner which can be considered as performing a filtering action.
  • the sequence of sections, of different diameter creates flow turbulence and prevent the running of work-over tools.
  • U.S. Pat. No. 5,435,393 describes a production pipe with a lover drainage pipe divided into sections and with one or more inflow restriction devices which controls the flow of oil or gas from the reservoir into the drainage pipe based on the precalculated loss of friction pressure along the drainage pipe, the precalculated production profile of the reservoir and the precalculated inflow of gas or water.
  • This publication does thus not relate to recompletion of old wells, nor to the use of autonomous flow control devices in said recompletion.
  • fluids of different qualities i.e. oil, gas, water (and sand) is produced in different amounts and mixtures depending on the property or quality of the formation.
  • known devices are able to distinguish between and control the inflow of oil, gas or water on the basis of their relative composition and/or quality.
  • an inflow control device which is self adjusting or autonomous and can easily be fitted in the wall of a production pipe and which therefore provide for the use of work-over tools.
  • the device is designed to “distinguish” between the oil and/or gas and/or water and is able to control the flow or inflow of oil or gas, depending on which of these fluids such flow control is required.
  • the device as disclosed in WO 2008/0048745 A1 is robust, can withstand large forces and high temperatures, needs no energy supply, can withstand sand production, is reliable, but is still simple and very cheap.
  • a problem with the prior art is that the well, with or without inflow control devices, has to be abandoned since the well is not able to produce anymore due to gas and/or water breakthrough.
  • Short-circuit effects might also appear in low oil zones with zones comprising gas and/or water above or below them.
  • the system and method according to the invention seeks to reduce or eliminate the above and other problems or disadvantages by inserting a pipe with a at least one, and preferably a plurality of autonomous valves into an existing well, and thus increase oil recovery with limited investments.
  • the invention might thus be regarded as an improvement of an existing stinger solution in which an impervious pipe section having solid walls are arranged on a location in the well in which gas breakthrough previously has been experienced.
  • FIG. 1 shows a schematic view of a production pipe with a control device according to WO 2008/0048745 A1
  • FIG. 2 a shows, in larger scale, a cross section of the control device according to WO 2008/0048745 A1, b ) shows the same device in a top view.
  • FIG. 3 is a diagram showing the flow volume through a control device according to the invention vs. the differential pressure in comparison with a fixed inflow device
  • FIG. 4 shows the device shown in FIG. 2 , but with the indication of different pressure zones influencing the design of the device for different applications.
  • FIG. 5 shows a principal sketch of another embodiment of the control device according to WO 2008/0048745 A1
  • FIG. 6 shows a principal sketch of a third embodiment of the control device according to WO 2008/0048745 A1

  • FIG. 8 shows a principal sketch of a fifth embodiment of WO 2008/0048745 A1 where the control device is an integral part of a flow arrangement.
  • FIG. 9 shows a principal view of a prior art well intersecting a high permeability zone of a reservoir.
  • FIG. 10 shows a principal view of the well in FIG. 9 , which, in accordance with the invention, is recompleted with a new pipe with autonomous valves inserted into the well, causing a substantially uniform inflow into the well.
  • FIG. 11 a shows a principal view of a lateral well in accordance with the invention, e.g. the well in FIG. 10 .
  • FIG. 11 b shows an enlarged principal view of the part of FIG. 11 a constricted by a circle.
  • FIG. 1 shows, as stated above, a section of a production pipe 1 in which a control device 2 , according to WO 2008/0048745 A1 is provided.
  • the control device 2 is preferably of circular, relatively flat shape and may be provided with external threads 3 (see FIG. 2 ) to be screwed into a circular hole with corresponding internal threads in the pipe or an injector.
  • the device 2 may be adapted to the thickness of the pipe or injector and fit within its outer and inner periphery.
  • FIG. 2 a ) and b ) shows the prior control device 2 of WO 2008/0048745 A1 in larger scale.
  • the device consists of a first disc-shaped housing body 4 with an outer cylindrical segment 5 and inner cylindrical segment 6 and with a central hole or aperture 10 , and a second disc-shaped holder body 7 with an outer cylindrical segment 8 , as well as a preferably flat disc or freely movable body 9 provided in an open space 14 formed between the first 4 and second 7 disc-shaped housing and holder bodies.
  • the body 9 may for particular applications and adjustments depart from the flat shape and have a partly conical or semicircular shape (for instance towards the aperture 10 .)
  • the cylindrical segment 8 of the second disc-shaped holder body 7 fits within and protrudes in the opposite direction of the outer cylindrical segment 5 of the first disc-shaped housing body 4 thereby forming a flow path as shown by the arrows 11 , where the fluid enters the control device through the central hole or aperture (inlet) 10 and flows towards and radially along the disc 9 before flowing through the annular opening 12 formed between the cylindrical segments 8 and 6 and further out through the annular opening 13 formed between the cylindrical segments 8 and 5 .
  • the two disc-shaped housing and holder bodies 4 , 7 are attached to one another by a screw connection, welding or other means (not further shown in the figures) at a connection area 15 as shown in FIG. 2 b ).
  • the present invention exploits the effect of Bernoulli teaching that the sum of static pressure, dynamic pressure and friction is constant along a flow line:
  • the pressure difference over the disc 9 can be expressed as follows:
  • a fluid such as gas will “make the turn later” and follow further along the disc towards its outer end (indicated by reference number 14 ). This makes a higher stagnation pressure in the area 16 at the end of the disc 9 , which in turn makes a higher pressure over the disc.
  • the disc 9 which is freely movable within the space between the disc-shaped bodies 4 , 7 , will move downwards and thereby narrow the flow path between the disc 9 and inner cylindrical segment 6 .
  • the disc 9 moves dawn-wards or up-wards depending on the viscosity of the fluid flowing through, whereby this principle can be used to control (close/open) the flow of fluid through of the device.
  • ⁇ ⁇ ⁇ p K ⁇ 1 2 ⁇ ⁇ ⁇ ⁇ v 2
  • K is mainly a function of the geometry and less dependent on the Reynolds number.
  • the flow area will decrease when the differential pressure increases, such that the volume flow through the control device will not, or nearly not, increase when the pressure drop increases.
  • FIG. 3 A comparison between a control device according to the present invention with movable disc and a control device with fixed flow-through opening is shown in FIG. 3 , and as can be seen from the figure, the flow-through volume for the present invention is constant above a given differential pressure.
  • the control device according to the invention may have two different applications: Using it as inflow control device to reduce inflow of water, or using it to reduce inflow of gas at gas break through situations.
  • the different areas and pressure zones as shown in FIG. 4 , will have impact on the efficiency and flow though properties of the device. Referring to FIG. 4 , the different area/pressure zones may be divided into:
  • Fluids with different viscosities will provide different forces in each zone depending on the design of these zones.
  • the design of the areas will be different for different applications, e.g. gas/oil or oil/water flow.
  • the areas needs to be carefully balanced and optimally designed taking into account the properties and physical conditions (viscosity, temperature, pressure etc.) for each design situation.
  • FIG. 5 shows a principal sketch of another embodiment of the control device according to WO 2008/0048745 A1, which is of a more simple design than the version shown in FIG. 2 .
  • the control device 2 consists, as with the version shown in FIG. 2 , of a first disc-shaped housing body 4 with an outer cylindrical segment 5 and with a central hole or aperture 10 , and a second disc-shaped holder body 17 attached to the segment 5 of the housing body 4 , as well as a preferably flat disc 9 provided in an open space 14 formed between the first and second disc-shaped housing and holder bodies 4 , 17 .
  • FIG. 6 shows a third embodiment according to WO 2008/0048745 A1 where the design is the same as with the example shown in FIG. 2 , but where a spring element 18 , in the form of a spiral or other suitable spring device, is provided on either side of the disc and connects the disc with the holder 7 , 22 , recess 21 or housing 4 .
  • a spring element 18 in the form of a spiral or other suitable spring device
  • the spring element 18 is used to balance and control the inflow area between the disc 9 and the inlet 10 , or rather the surrounding edge or seat 19 of the inlet 10 .
  • the opening between the disc 9 and edge 19 will be larger or smaller, and with a suitable selected spring constant, depending on the inflow and pressure conditions at the selected place where the control device is provided, constant mass flow through the device may be obtained.
  • FIG. 7 shows a fourth embodiment according to WO 2008/0048745 A1, where the design is the same as with the example in FIG. 6 above, but where the disc 9 is, on the side facing the inlet opening 10 , provided with a thermally responsive device such as bi-metallic element 20 .
  • the conditions may rapidly change from a situation where only or mostly oil is produced to a situation where only or mostly gas is produced (gas breakthrough or gas coning).
  • gas breakthrough or gas coning With for instance a pressure drop of 16 bar from 100 bar the temperature drop would correspond to approximately 20° C.
  • the disc 9 With a thermally responsive element such as a bi-metallic element as shown in FIG. 7 , the disc will bend upwards or be moved upwards by the element 20 abutting the holder shaped body 7 and thereby narrowing the opening between the disc and the inlet 10 or fully closing said inlet.
