The present disclosure relates generally to wellbore operations and, more particularly (although not necessarily exclusively), to flow control devices for brine production from a wellbore.
Wellbore operations may include various equipment, components, methods, or techniques to form a wellbore, to displace and release produced material, such as hydrocarbons, water, and the like, using a wellbore or flowline, and the like. The wellbore may be formed in a subterranean formation, a suboceanic formation, or the like, and the wellbore may be used to produce fluids or other suitable material from the subterranean formation, the suboceanic formation, or the like. Isolating a particular produced material to be produced via the wellbore is technically challenging.
Certain aspects and examples of the present disclosure relate to a set of flow control devices that can be positioned in a wellbore to facilitate brine production via the wellbore. The wellbore may be formed or otherwise positioned in a subterranean formation, a suboceanic formation, or other suitable geological formation that may include hydrocarbon material, lithium-rich brine, brine with other or additional alkali metals or alkaline earth metals, and the like. The set of flow control devices can be positioned in the wellbore to control a flow of one or more materials with respect to the wellbore. For example, a first flow control device can be positioned in a first isolated zone of the wellbore to control flow of a first material, and a second flow control device can be positioned in a second isolated zone of the wellbore to control flow of a second material. The first material may be hydrocarbon material or other material that may not include alkali-rich brine. The second material may be different than the first material and may include alkali-rich brine such as a brine that includes a significant concentration of Lithium, Sodium, Potassium, and the like.
Wellbores can be formed or otherwise positioned in geological formations, such as subterranean formations, suboceanic formations, and the like, to produce material such as hydrocarbon material, brine, and the like. In some examples, a wellbore may be formed to produce hydrocarbon material without brine, to produce a particular type of brine while restricting other material, such as hydrocarbon material, etc., and the like. A wellbore formed or otherwise used to produce brine may extract lithium-rich brine, which may be or include brine that includes a significant concentration (e.g., more than 0.5%, more than 1%, more than 5%, more than 10%, etc.) of lithium. Additionally or alternatively, wellbores that may have originally been formed to produce hydrocarbons may be reconfigured to produce the lithium-rich brine. In these wellbores, and, in some examples, with respect to other wellbores, producing lithium-rich brine may additionally involve producing unwanted material such as hydrocarbon material, non-lithium-containing brine, and the like. Producing the unwanted material may increase a complexity of a wellbore operation involving the wellbores, may involve using excessive resources, such as via surface processing, flaring, etc., and the like.
A set of flow control devices can be positioned in a wellbore to control flow of multiple materials with respect to the wellbore. The set of flow control devices can include two or more flow control devices, three or more flow control devices, four or more flow control devices, or more. In some examples, a flow control device, such as two or more flow control devices included in the set of flow control devices, can be or include a density autonomous inflow control device, an electric inflow control device, a viscosity autonomous inflow control device, other inflow control devices, or any combination thereof. A density autonomous inflow control device can be or include a flow control device that can autonomously determine to encourage flow of a material or restrict flow of the material based at least in part on a density of the material. For example, the density autonomous inflow control device can receive a material and can encourage flow of the material if a density of the material exceeds a threshold density.
A viscosity autonomous inflow control device can be or include a flow control device that can autonomously determine to encourage flow of a material or restrict flow of the material based at least in part on a viscosity of the material. For example, the viscosity autonomous inflow control device can receive a material and can encourage flow of the material if a viscosity of the material exceeds a threshold viscosity. An electric inflow control device can be or include a flow control device that can measure, such as directly or indirectly, a composition of a material to determine whether to encourage or restrict flow of the material. For example, the electric inflow control device can receive a material and can use one or more sensors to measure or otherwise determine a composition of the material to determine whether to encourage or restrict flow of the material.
Using a density autonomous inflow control device, a viscosity autonomous inflow control device, an electric inflow control device, other types of inflow control devices, or any combination thereof can optimize flow in a wellbore. For example, the set of flow control devices can be arranged in the wellbore or otherwise used to minimize flow of hydrocarbons, non-alkali-metal-containing brines, and other unwanted production material. Additionally or alternatively, the set of flow control devices can be arranged in the wellbore or otherwise used to enhance production of brines or other production material that may include lithium or other alkali metals. In a particulate example, a target fluid, such as a lithium-rich brine, may be produced using a density autonomous inflow control device valve that may be positioned in the wellbore to choke hydrocarbon material, such as oil or gas, and produce the target fluid. In another example, a fluidic diode, or an electric inflow control device, may be positioned in the wellbore to restrict hydrocarbon material, such as oil or gas, and to produce water or lithium-rich brine based on the electric inflow control device measuring the target fluid.
In some examples, a density autonomous inflow control device can include an inlet port, an outlet port, a rotatable component for rotating about an axis in response to fluid flow from the inlet port, and any other suitable components. The rotatable component can include a float component that can move between (i) an open position that enables fluid flow from the inlet port to the outlet port, and (ii) a closed position that restricts fluid flow from the inlet port to the outlet port. The float component can move to the closed position when a higher-density fluid, such as water, lithium-containing brine, etc., flows through the density autonomous inflow control device at least in part due to a force that is applied to the float component as the rotatable component rotates. Additionally or alternatively, the float component can move to the open position when a lower-density fluid, such as oil or gas, flows through the fluid flow control device at least in part due to the force. This can enable the lower-density fluid to flow out of the outlet port. In this manner, the fluid flow control device can selectively control fluid flow to the outlet port based on the density of the fluid.
In some examples, the flow control devices may be used in wellbores that may support operations to inject material into a subterranean formation, operations to produce material from the subterranean formation, or a combination thereof. For example, the flow control devices may be positioned in a wellbore and may inject carbon dioxide or other suitable materials into the subterranean formation. The carbon dioxide may be injected into the subterranean formation to sequester the carbon dioxide, to enhance recovery of lithium-rich brines or alkali-metal-rich brines, to perform other suitable operations, or any combination thereof. Additionally or alternatively, the flow control devices may facilitate hydraulic fracturing with respect to the subterranean formation to enhance recovery of the lithium-rich brines or the alkali-metal-rich brines.
These illustrative examples are given to introduce the reader to the general subject matter discussed herein and are not intended to limit the scope of the disclosed concepts. The following sections describe various additional features and examples with reference to the drawings in which like numerals indicate like elements, and directional descriptions are used to describe the illustrative aspects, but, like the illustrative aspects, should not be used to limit the present disclosure.

The first location 108a may be offset from the second location 108b in a direction that follows the path of an axis 110 of the wellbore 100.
The downhole tools 104a-b may be used to control flow of one or more materials with respect to the wellbore 100, the subterranean formation 102, or a combination thereof. For example, the first downhole tool 104a, the second downhole tool 104b, or a combination thereof may inject fluid, such as wellbore fluid, into the subterranean formation 102 to stimulate production of one or more materials from the subterranean formation 102. Additionally or alternatively, the first downhole tool 104a, the second downhole tool 104b, or a combination thereof may receive one or more materials from the subterranean formation 102. The one or more materials may be or include hydrocarbon material, brine, or the like. The first downhole tool 104a, the second downhole tool 104b, or a combination thereof may determine whether to produce or choke the one or more materials based on properties associated with the one or more materials.

The set of flow control devices 202 can be positioned downhole in the wellbore 200. The set of flow control devices 202 may be or include one or more types of inflow control devices, such as a density autonomous inflow control device, a viscosity autonomous inflow control device, an electric inflow control device, and the like.

The set of flow control devices 202 may be used to control flow of one or more materials with respect to the wellbore 200, the subterranean formation 204, or a combination thereof. For example, the first flow control device 206a, the second flow control device 206b, the third flow control device 206c, or any combination thereof may inject fluid, such as wellbore fluid, into the subterranean formation 204 to stimulate production of one or more materials from the subterranean formation 204.

As illustrated in
In some examples, each flow control device of the set of flow control devices 202, or any subset thereof, may directly measure one or more properties of received material, may indirectly measure the one or more properties of the received material, or may otherwise suitably determine whether to choke or produce the received material. For example, if a flow control device is or includes an electric inflow control device, the flow control device may use one or more sensors or other equipment to measure a density of the received material, a viscosity of the received material, a composition (e.g., a level of lithium or other alkali metals) of the received material, and the like. The flow control device may determine to choke the received material by closing a valve or by otherwise restricting production of the received material. In some examples, the flow control device may determine to produce the received material by opening the valve. In examples in which the flow control device is or includes a density autonomous inflow control device, the flow control device may produce the received material if the density of the received material exceeds a threshold density, and the flow control device may choke the received material if the density of the received material does not exceed the threshold density.
The material 302 may enter the electric inflow control device 304 via the receiving path 308 and may contact the valve 314. The set of sensors 310, which may be or include temperature sensors, composition sensors, density sensors, and the like, may detect one or more properties of the material 302 and may cause the electric inflow control device 304 to determine whether to produce or choke the material 302 by retaining the valve 314 closed or opening the valve 314, respectively. If the set of sensors 310 detects the one or more properties indicating that the material 302 is, or is likely to be, brine that includes a significant concentration of alkali metals, then the electric inflow control device 304 may, for example using electrical power, cause the valve 314 to open and may produce the material 302. If the set of sensors 310 detects the one or more properties indicating that the material 302 is not, or is not likely to be, brine that includes a significant concentration of alkali metals, then the electric inflow control device 304 may cause the valve 314 to remain closed and may choke the material 302. In examples in which the valve 314 is opened, the material 302 may proceed into a production bore 316 and can be produced as produced alkali-metal-rich brine 318. In examples in which the valve 314 remains closed, the material 302 may not proceed to the production bore 316 and may be choked.
As illustrated in the block diagram 300b, the density autonomous inflow control device 306 may be positioned in the wellbore 200. The density autonomous inflow control device 306 may include a receiving path 319, a rotatable component 320, and any other suitable component for providing functionality for the density autonomous inflow control device 306. The receiving path 308 may extend from an external surface 322 of the density autonomous inflow control device 306 to the rotatable component 320 that may be located adjacent to a production bore 324 of the density autonomous inflow control device 306.
The material 302 may enter the density autonomous inflow control device 306 via the receiving path 319 and may contact the rotatable component 320, which may be fluidically coupled with a valve. The valve may initially be in a closed state and may rotate to open and allow the material 302 to flow into the production bore 324 of the density autonomous inflow control device 306 based on one or more properties of the material 302 sensed or inferred by the rotatable component 320. For example, if the material 302 has a density that exceeds a threshold density, then the valve may, for example using mechanical power supplied by the material 302, open and may allow the density autonomous inflow control device 306 to produce the material 302. The threshold density may be a density that indicates a material is likely to have a significant concentration of lithium or other alkali metals. if the material 302 has a density that does not exceed the threshold density, then the valve may remain closed and may cause the density autonomous inflow control device 306 to choke the material 302. In examples in which the valve opens, the material 302 may proceed into the production bore 324 and can be produced as produced alkali-metal-rich brine 318. In examples in which the valve remains closed, the material 302 may not proceed to the production bore 324 and may be choked.
At block 404, the first flow control device determines to restrict flow of the first material based at least in part on one or more properties (e.g., fluid properties) of the first material. The first flow control device may identify the first material, may infer one or more properties of the first material, or the like to determine whether to restrict the flow of the first material. For example, if the first flow control device is an electric inflow control device, then the first flow control device may use one or more sensors, lasers, and the like to identify at least an approximate composition of the first material, at least a set of fluid properties associated with the first material, and the like. In this example, the first flow control device may receive the first material and may measure a lithium content of the first material or a concentration of alkali metals included in the first material. The first flow control device may identify that the first material includes no lithium or other alkali metals, or the first flow control device may identify that the first material includes negligible, or insignificant amounts (e.g., less than approximately 40%, less than approximately 20%, less than approximately 10%, less than approximately 5%, less than approximately 1%, less than approximately 0.1%, etc.), of lithium or other alkali metals.
In other examples, the first flow control device may be or include a density autonomous inflow control device. In these examples, the first flow control device may produce material or choke material mechanically based on a density of received material. The first flow control device can receive the first material, and, if the first material has a density that exceeds a threshold density, then the first flow control device may produce or encourage production of the first material. If the first material has a density that does not exceed the threshold density, then the first flow control device may choke or otherwise restrict production of the first material. At the block 404, the first flow control device may restrict production of the first material in response to the first flow control device receiving the first material and the first material not having a density that exceeds the density threshold. In some examples, the density threshold may be similar or identical to an expected density of brine that includes a significant concentration (e.g., greater than approximately 10%, greater than approximately 20%, greater than approximately 50%, greater than approximately 75%, etc.) of lithium or other alkali metals.
At block 406, a second flow control device, such as the second flow control device 206b, receives a second material. The second flow control device may be positioned in a wellbore, such as the wellbore 200, and may be positioned in a second particular isolated zone, such as the second isolated zone 208b, of the wellbore. The second flow control device may be positioned offset, such as along the axis 212 of the wellbore 200, from the first flow control device and may be positioned in or adjacent to a different isolated zone of the wellbore with respect to the first flow control device.
The second flow control device may be or include an electric inflow control device, a density autonomous inflow control device, a viscosity autonomous inflow control device, or any other suitable type of flow control device that can be positioned and used in the wellbore. In some examples, the second flow control device may be the same or similar type of flow control device as the first flow control device. In other examples, the second flow control device may be different than the first flow control device. The second flow control device may receive the second material via or from the second particular isolated zone. In some examples, the second material may be or include a brine or brine-like material. The second material may include significant concentrations (e.g., greater than approximately 5%, greater than approximately 10%, greater than approximately 20%, greater than approximately 40%, greater than approximately 75%, etc.) of alkali metals such as lithium, sodium, potassium, rubidium, and the like. The second flow control device may receive the second material at a valve or other actuatable component that may allow the second flow control device to choke or produce the first material.
At block 408, the second flow control device determines to produce the second material based on one or more properties, such as fluid properties, of the second material. The second flow control device may identify the second material, may infer the one or more properties of the second material, or the like to determine whether to produce or encourage the flow of the second material. For example, if the second flow control device is an electric inflow control device, then the second flow control device may use one or more sensors, lasers, and the like to identify at least an approximate composition of the second material, at least a set of fluid properties associated with the second material, and the like. In this example, the second flow control device may receive the second material and may measure a lithium content of the second material or a concentration of alkali metals included in the second material. The second flow control device may identify that the second material includes significant amounts (e.g., greater than approximately 5%, greater than approximately 10%, greater than approximately 20%, greater than approximately 40%, greater than approximately 75%, etc.) of lithium or other alkali metals.
In other examples, the second flow control device may be or include a density autonomous inflow control device. In these examples, the second flow control device may produce material or choke material mechanically based on a density of received material. The second flow control device can receive the second material, and, if the second material has a density that exceeds a threshold density, then the second flow control device may produce or encourage production of the second material. If the second material has a density that does not exceed the threshold density, then the second flow control device may choke or otherwise restrict production of the second material. At the block 408, the second flow control device may produce or encourage production of the second material in response to the second flow control device receiving the second material and the second material having a density that exceeds the threshold density. In some examples, the density threshold may be similar or identical to an expected density of brine that includes a significant concentration (e.g., greater than approximately 10%, greater than approximately 20%, greater than approximately 50%, greater than approximately 75%, etc.) of lithium or other alkali metals.
