- Referring initially to
FIG. 1 , there is shown anexemplary wellbore 10 that has been drilled through theearth 12 and into a pair offormations wellbore 10 is cased by metal casing, as is known in the art, and a number ofperforations 18 penetrate and extend into theformations formations wellbore 10. Thewellbore 10 has a deviated or substantiallyhorizontal leg 19. Thewellbore 10 has a late-stage production assembly, generally indicated at 20, disposed therein by atubing string 22 that extends downwardly from awellhead 24 at thesurface 26 of thewellbore 10. Theproduction assembly 20 defines an internal axial flow bore 28 along its length. Anannulus 30 is defined between theproduction assembly 20 and the wellbore casing. Theproduction assembly 20 has a deviated, generallyhorizontal portion 32 that extends along the deviatedleg 19 of thewellbore 10.Production nipples 34 are positioned at selected points along theproduction assembly 20. Optionally, each production nipple 34 is isolated within thewellbore 10 by a pair ofpacker devices 36. Although only afew production nipples 34 are shown inFIG. 1 , there may, in fact, be a large number of such nipples arranged in serial fashion along thehorizontal portion 32. - Each production nipple 34 features a
production control device 38 that is used to govern one or more aspects of a flow of one or more fluids into theproduction assembly 20. As used herein, the term “fluid” or “fluids” includes liquids, gases, hydrocarbons, multi-phase fluids, mixtures of two of more fluids, water, brine, engineered fluids such as drilling mud, fluids injected from the surface such as water, and naturally occurring fluids such as oil and gas. In accordance with embodiments of the present disclosure, theproduction control device 38 may have a number of alternative constructions that ensure selective operation and controlled fluid flow therethrough. -
FIG. 2 illustrates an exemplaryopen hole wellbore 11 wherein the production devices of the present disclosure may be used. Construction and operation of theopen hole wellbore 11 is similar in most respects to the wellbore 10 (FIG. 1 ) described previously. However, thewellbore arrangement 11 has an uncased borehole that is directly open to theformations formations annulus 30 that is defined between theproduction assembly 21 and the wall of thewellbore 11. There are no perforations, and thepackers 36 may be used to separate the production nipples. However, there may be some situations where thepackers 36 are omitted. The nature of the production control device is such that the fluid flow is directed from theformation 16 directly to thenearest production nipple 34. - Referring now to
FIG. 3 , there is shown one embodiment of a production orinjection control device 100 for controlling the flow of fluids between a reservoir and a flow bore 102 of a tubular 104 along a production string (e.g.,tubing string 22 ofFIG. 1 ). Thecontrol devices 100 may be distributed along a section of a production well to provide fluid control at multiple locations. This can be useful, for example, to impose a desired drainage or production influx pattern. By appropriately configuring theproduction control devices 100, a well owner can increase the likelihood that an oil or gas bearing reservoir will drain efficiently. This drainage pattern may include equal drainage from all zones or individualized and different drainage rates for one or more production zones. During injection operations, wherein a fluid such as water or steam is directed into the reservoir, thedevices 100 may be used to distribute the injected fluid in a desired manner. Exemplary production control devices are discussed herein below. - In one embodiment, the
production control device 100 includes aparticulate control device 110 for reducing the amount and size of particulates entrained in the fluids and in-flow control devices 120 a,b that control overall drainage rate from the formation. Theparticulate control device 110 can include known devices such as sand screens and associated gravel packs. In embodiments, the in-flow control devices 120 a,b utilizes flow channels and/or other geometries that control in-flow rate and/or the type of fluids entering the flow bore 102 of a tubular 104 via one or more flow bore openings 106. Illustrative embodiments are described below. - In one embodiment, the in-
flow control devices 120 a and 120 b are positioned at opposing ends of theparticulate control device 110. The in-flow control devices 120 a,b each include flow passages 122 a,b that may include channels, orifices bores, annular spaces and/or hybrid geometry, that are constructed to generate a desired pressure differential across the in-flow devices 120 a,b. By hybrid, it is meant that a give flow passage may incorporate two or more different geometries (e.g., shape, dimensions, etc.). The flow passages 122 a,b are configured to convey fluid between theparticulate control device 110 and the flow bore 102 along parallel and directionally opposing flow paths. By parallel, it is meant that the flow paths have a common origin and end point. By directionally opposing, it is meant that the flow passage 122 a directs the fluid in an axial direction opposite to the axial direction of the fluid in the flow passage 122 b. It should be understood, however, that the flow passages 122 a,b may utilize helical channels, radial channels, circular channels, etc. That is, the flow direction of the flow passages 122 a,b may use directional components in addition to an axial component. Also, in embodiments, the pressure control may be configured such that the pressure drop along theparticulate control device 110 is substantially lower than the pressure drop in the pressure drop along the in-flow control devices 120 a, 120 b. This pressure drop may be the drop associated with the fluid flowing through the wall of the filtration media (e.g., the screen) and/or the fluid flowing between the wall of the filtration media and the base pipe 108. By “substantially,” it is meant an order of magnitude lower pressure drop. It should be noted that the fluid flow along theparticulate control device 110 also has portions wherein two or more fluids streams have parallel and directionally opposite flows. That is, the flow paths between the base pipe 108 and the wall of theparticulate control device 110 may direct flow substantially parallel to the long axis of the tool and in opposing directions. - During one exemplary use, a fluid F (liquid, gas, steam or mixture) may initially flow radially into the
particulate control device 110 and split into a first fluid stream F1 and a second fluid stream F2. The fluid stream F1 flows through theinflow control device 120 a, which causes a pre-determined pressure drop in the fluid stream F1. Thereafter, the fluid stream flows through openings 106 into the flow bore 102. Similarly, the fluid stream F2 flows through the inflow control device 120 b, which causes a pre-determined pressure drop in the fluid stream F2. Thereafter, the fluid stream flows through openings 106 into the flow bore. The pressure drops in the fluid streams F1 and F2 may be the same or different. It should be noted that no fluid enters the flow bore 102 radially through a section 108 of the base pipe that is radially inward of theparticulate control device 110. That is, all the fluid enters the flow bore at a location either uphole or downhole of theparticulate control device 110. - While the teachings of the present disclosure may be applied to a variety of situations, certain embodiments of the present disclosure may be useful in controlling inflow patterns in relatively high-velocity flow rate situations. Referring now to
FIG. 4 , there is shown aproduction control device 150 disposed in a wellbore. The in-flow control device 150 may include aparticulate control device 152 and an in-flow control device 154. Apermeable material 156 may partially or completely fill anannular space 157 surrounding theparticulate control device 152. Thispermeable material 156 may be a naturally occurring material such as sand that, over time, invaded thewellbore 152. Thepermeable material 156 may also be an engineered material such as gravel that has been pumped in from the surface. Thepermeable material 156 may act as a modulating media that moderates or distributesfluid flow 158 across the axial length of theparticulate control device 152. Thus, the velocity of the fluid 160 flowing into thejuncture 162 between theparticulate control device 152 and the in-flow control device 154 may be significantly greater than the fluid inflow velocity at adistal point 164 on the particulate control device. - Referring now to
FIG. 5 , there is shown theFIG. 3 embodiment wherein the in-flow control devices 120 a and 120 b are positioned at opposing ends of theparticulate control device 110. Theannular space 170 around theparticulate control device 110 does not include a flow modulating media. Rather, theannular space 170 may be open (standalone completion), include a material that is functionally the equivalent of an open space or include a permeable material (gravel pack completion), at least in terms of providing resistance to fluid flow. For purposes of this disclosure, the functional equivalent of an open space may be a material having a permeability of no less than 50 Darcy or a material that does not offer flow resistance in the radial and lineal direction. - In one situation, the formation may produce a fluid at a relatively high velocity, e.g., a gas or
steam 172. It will be appreciated that if only one in-flow control device was present, e.g., in-flow control device 120 a, then all of thegas 172 would flow through thejuncture 174 between theparticulate control device 110 and the in-flow control device 120 a. The relatively high velocity may cause undesirable corrosion and/or erosion in the vicinity of thejunction 174. Because two in-flow control devices are present, thegas 172 is divided into twostreams stream gas 172. Thus, the flow velocity at thejuncture 174 has been reduced by approximately one-half, which reduces the amount of possible material degradation in the vicinity of thejuncture 174. Additional in-flow control device can be considered but the solution will be restricted by the joint length. - From the above, it should be appreciated that what has been described includes, in part, an apparatus for controlling a flow of a fluid between a wellbore tubular and a wellbore annulus. The apparatus may include a particulate control device configured to be disposed in the wellbore; and two (or more) parallel and directionally opposing flow paths in fluid communication with the particulate control device. The flow paths may be configured to generate a substantially greater pressure drop than the particulate control device. A first flow path of the flow paths may be in fluid communication with a first end of the particulate control device and a second flow path of the flow paths may be in fluid communication with a second end of the particulate control device. The first and second ends may at opposite ends of the particulate control device. The particulate control device may include a fluid impermeable base pipe portion that may be radially inward of the particulate control device. The flow paths may be configured to generate a minimum flow into the particulate control device at a substantially medial location along the particulate control device. The particulate control device may be configured to generate fluid streams flowing in axially opposing directions.
- From the above, it should be appreciated that what has been described also includes, in part, a method for controlling a flow of a fluid between a wellbore tubular and a wellbore annulus. The method may include separating a fluid flowing from a formation surrounding the wellbore into two (or more) parallel streams flowing in opposing directions; and generating a pressure drop in the streams. The method may include filtering the fluid before separating the fluid into parallel streams. The method may also include generating a substantially greater pressure drop in the streams than during filtering. The fluid may be filtered at a selected location in the wellbore, and the pressure drops may be generated uphole and downhole of the selected location. The method may include receiving a gas from the formation, the gas being the fluid. Also, the gas may be received through an open annular space.
- From the above, it should be appreciated that what has been described further includes, in part, a method for control a flow of a fluid between a wellbore tubular and a wellbore annulus. The method may include separating a fluid flowing between the wellbore annulus and a bore of the wellbore tubular into two (or more0 parallel streams flowing in opposing directions; and generating a pressure drop in the streams.
- It should be understood that the teachings of the present disclosure may readily be applied to other situations such as geothermal wells, water producing wells, etc.
- For the sake of clarity and brevity, descriptions of most threaded connections between tubular elements, elastomeric seals, such as o-rings, and other well-understood techniques are omitted in the above description. Further, terms such as “slot,” “passages,” and “channels” are used in their broadest meaning and are not limited to any particular type or configuration. The foregoing description is directed to particular embodiments of the present disclosure for the purpose of illustration and explanation. It will be apparent, however, to one skilled in the art that many modifications and changes to the embodiment set forth above are possible without departing from the scope of the disclosure.
