     BACKGROUND 
     Many reservoirs containing vast quantities of oil have been discovered in subterranean formations; however, the recovery of oil from some subterranean formations has been very difficult due to the relatively high viscosity of the oil and/or the presence of viscous tar sands in the formations. In particular, when a production well is drilled into a subterranean formation to recover oil residing therein, often little or no oil flows into the production well even if a natural or artificially induced pressure differential exits between the formation and the well. To overcome this problem, various thermal recovery techniques have been used to decrease the viscosity of the oil and/or the tar sands, thereby making the recovery of the oil easier. 
     One such thermal recovery technique utilizes steam to thermally stimulate viscous oil production by injecting steam into a wellbore to heat an adjacent subterranean formation. Conventional steam injections tools, systems, and/or methods may provide steam injection at a predetermined constant flow rate to stimulate viscous oil production. Further, the steam is typically injected such that it is not evenly distributed throughout the well bore, resulting in a temperature gradient along the well bore. The cold spots may lead to the formation of condensation within a steam injection tool and thereby form water deposits within the steam injection tool and/or a wellbore. As such, there is a need for apparatuses, systems, and methods of increasing the efficiency and performance of a steam injection operation, as well as, controlling the water deposits generated by condensation during a steam injection operation. 
     SUMMARY 
     In an embodiment, a steam injection mandrel comprises a housing generally defining an axial flow bore and comprising one or more ports, an inner mandrel disposed within the housing, and a slot formed in the inner mandrel. The slot transitions at least three hundred sixty degrees about the longitudinal axis of the housing, and the steam injection mandrel is configured to provide fluid communication between the axial flow bore and the one or more ports through the slot. The steam injection mandrel may also include an annular region defined between an interior surface of the housing and an exterior surface of the inner mandrel, and a valve sleeve disposed within the annular region. The valve sleeve may be configured to selectively adjust a resistance to fluid flow between the axial flow bore and the one or more ports. The valve sleeve may be configured to be positioned to partially restrict or substantially restrict a route of fluid communication via the ports. The inner mandrel may comprise a helical slot, the helical slot may comprise a ported cover. The steam injection mandrel may also include an adjustment mechanism coupled to the valve sleeve, and the adjustment mechanism may be configured to position the valve sleeve. The adjustment mechanism may comprise a ratchet mechanism comprising a plurality of continuous slots. The slot may comprise one or more decision paths, and the slot may be configured to guide an adjustment tool into engagement with the ratchet mechanism. The adjustment mechanism may comprises a continuous j-slot coupled to a valve sleeve, the valve sleeve may be configured to selectively adjust a resistance to fluid flow between the axial flow bore and the one or more ports. The one or more ports may be in fluid communication with an exterior of the steam injection mandrel. 
     In an embodiment, a wellbore system comprises a tubular string having an axial flow bore disposed in a wellbore within a subterranean formation, and a downhole adjustable steam injection mandrel coupled to the tubular string. The downhole adjustable steam injection mandrel comprises an adjustment mechanism comprising a plurality of continuous slots coupled to a valve sleeve, and the valve sleeve is configured to selectively adjust a resistance to fluid flow between the axial flow bore and the subterranean formation. The axial flow bore may be configured to receive an adjustable selector tool, and the adjustable selector tool may be configured to engage one of the plurality of continuous slots and selectively increase or decrease the resistance to fluid flow between the axial flow bore and the subterranean formation. The system may also include one or more packers disposed about the tubular string, and the one or more packers may be configured to isolate one or more portions of the wellbore. The adjustment mechanism may comprise a ratchet mechanism that is configured to rotate in response to an axial cycling of an adjustable selector tool. The valve sleeve may be configured to axial translate in response to a rotation of the ratchet mechanism. 
     In an embodiment, a wellbore servicing method comprises disposing an adjustable selector tool within an axial flow bore of a downhole adjustable steam injection mandrel, engaging a continuous slot in an adjustment mechanism, rotating the adjustment mechanism using the adjustable selector tool, and selectively adjusting a resistance to the flow of a fluid between the axial flow bore and a subterranean formation in response to rotating the adjustment mechanism. Engaging the continuous slot in the adjustment mechanism may comprises: engaging the adjustable selector tool with a helical slot disposed in an inner mandrel of the downhole adjustable steam injection mandrel; and guiding the adjustable selector tool into engagement with the continuous slot using the helical slot. The adjustment mechanism may comprise a second continuous slot, and guiding the adjustable selector tool into engagement with the continuous slot using the helical slot may comprise: traversing one or more decision paths leading to the second continuous slot. Rotating the adjustment mechanism may comprise: axially cycling the adjustment mechanism; and rotating the adjustment mechanism in response to the axial cycling. The method may also include passing any liquid flowing along an interior surface of the axial flow bore through an axial discontinuity in an inner mandrel of the downhole adjustable steam injection mandrel. The axial discontinuity may comprise a helical slot disposed in the inner mandrel.

     Disclosed herein are embodiments of wellbore servicing apparatuses, systems and methods of using the same. Particularly disclosed herein are one or more embodiments of a wellbore servicing tool, systems, and methods utilizing the same. In an embodiment, the wellbore servicing system may generally comprise a downhole adjustable steam injection mandrel (DASIM)  200  and an adjustable selector tool (AST)  300 , as will be disclosed herein. In one or more of the embodiments as will be disclosed herein, the wellbore servicing system may be generally configured to selectively adjust the flow rate of fluid communication between an interior portion and an exterior portion of the DASIM  200 , for example, during the performance of a wellbore servicing operation (e.g., a subterranean formation stimulation operation). 
     Referring to  FIG. 1 , an embodiment of an operating environment in which a wellbore servicing system  100  is illustrated. As depicted in  FIG. 1 , the operating environment generally comprises a wellbore  114  that penetrates a subterranean formation  102  for the purpose of recovering hydrocarbons, storing hydrocarbons, disposing of carbon dioxide, or the like. The wellbore  114  may be drilled into the subterranean formation  102  using any suitable drilling technique. In an embodiment, a drilling or servicing rig  106  disposed at the surface  104  comprises a derrick  108  with a rig floor  110  through which a work string (e.g., a drill string, a tool string, a segmented tubing string, a jointed tubing string, or any other suitable conveyance, or combinations thereof) generally defining an axial flow bore  126  may be positioned within or partially within wellbore  114 . In an embodiment, such a work string may comprise two or more concentrically positioned strings of pipe or tubing (e.g., a first work string may be positioned within a second work string). The drilling or servicing rig may be conventional and may comprise a motor driven winch and other associated equipment for lowering the work string into wellbore  114 . Alternatively, a mobile workover rig, a wellbore servicing unit (e.g., coiled tubing units), or the like may be used to lower the work string into the wellbore  114 . In such an embodiment, the work string may be utilized in drilling, stimulating, completing, or otherwise servicing the wellbore, or combinations thereof. 
     The wellbore  114  may extend substantially vertically away from the earth&#39;s surface over a vertical wellbore portion, or may deviate at any angle from the earth&#39;s surface  104  over a deviated or horizontal wellbore portion  118 . In alternative operating environments, portions or substantially all of wellbore  114  may be vertical, deviated, horizontal, and/or curved and such wellbore may be cased, uncased, or combinations thereof. In some instances, at least a portion of the wellbore  114  may be lined with a casing  120  that is secured into position against the formation  102  in a conventional manner using cement  122 . In this embodiment, the deviated wellbore portion  118  includes casing  120 . However, in alternative operating environments, the wellbore  114  may be partially cased and cemented thereby resulting in a portion of the wellbore  114  being uncased. In an embodiment, a portion of wellbore  114  may remain uncemented, but may employ one or more packers  124  (e.g., mechanical and/or swellable packers, such as Swellpackers™, commercially available from Halliburton Energy Services, Inc.) to isolate two or more adjacent portions or zones within wellbore  114  and/or to isolate a DASIM  200 . It is noted that although some of the figures may exemplify a horizontal or vertical wellbore, the principles of the apparatuses, systems, and methods disclosed may be similarly applicable to horizontal wellbore configurations, conventional vertical wellbore configurations, and combinations thereof. Therefore, the horizontal or vertical nature of any figure is not to be construed as limiting the wellbore to any particular configuration. 
     Referring to  FIG. 1 , a wellbore servicing system  100  is illustrated. In the embodiment of  FIG. 1 , the wellbore servicing system  100  comprises the DASIM  200  incorporated with a tubular string  112  (e.g., a casing string, a production string, etc.) and positioned within the wellbore  114 . Additionally, in an embodiment the wellbore servicing system  100  may further comprise an adjustable selector tool  300 . In such an embodiment, the AST  300  may be positionable within the tubular string  112 , for example, via a work string  301  (e.g., a slick line, a wire line, etc.) along the axial flow bore  126  of the work string  112 . Also, in such an embodiment, the tubular string  112  may be positioned within the wellbore  114  such that the DASIM  200  is positioned proximate and/or substantially adjacent to one or more zones of the subterranean formation  102 . 
     The AST  300  may be generally configured to adjust and/or configure the DASIM  200 , for example, to improve the performance of one or more servicing operations, as will be disclosed herein. While this disclosure may refer to a DASIM  200  configured for a stimulation operation (e.g., a steam injection operation), as disclosed herein, a wellbore servicing tool incorporated with the wellbore servicing system may be configured for various additional or alternative operations and, as such, this disclosure should not be construed as limited to utilization in any particular wellbore servicing context unless so-designated. In an embodiment, the DASIM  200  may be adjustable and/or configurable, for example, being configured to adjust the flow rate of fluid communication from the DASIM  200  to the wellbore  114 , the subterranean formation  102 , and/or a zone thereof. In such an embodiment, the DASIM  200  may be configured for adjustment via the operation of a second wellbore servicing tool (e.g., an AST  300 ). Although the embodiment of  FIG. 1  illustrates three DASIM  200  (e.g., being positioned substantially proximate or adjacent to a formation), one of skill in the art viewing this disclosure will appreciate that any suitable number of wellbore servicing tools may be similarly incorporated within a tubular string  112 , for example, 1, 2, 4, 5, 6, 7, 8, 9, 10, etc. wellbore servicing tools. 
     In an embodiment, the DASIM  200  may be generally configured to provide a route of fluid communication between the axial flow bore  126  of the tubular string  112  and the exterior of the DASIM  200  (e.g., the wellbore  114 ), for example, to perform one or more wellbore servicing operations (e.g., a steam injection treatment). Additionally, the DASIM  200  is configured to transition between a plurality of configurations to provide an adjustable fluid flow rate. 
     Referring to  FIGS. 2A-2B , an embodiment of a DASIM  200  is illustrated in a first configuration. In an embodiment, when the DASIM  200  is in the first configuration, the DASIM  200  may be configured so as to disallow (e.g., substantially prevent) fluid communication between the interior of the DASIM  200  (e.g., an axial flow bore) and the exterior of the DASIM  200 . In an embodiment, as is disclosed herein, the DASIM  200  may be configured to transition from the first configuration to a second configuration upon actuation (e.g., via the AST  300 ) of a ratchet mechanism  250  in a first direction, as will be disclosed herein. 
     Referring to  FIGS. 3A-3B , an embodiment of a DASIM  200  is illustrated in a second configuration. In an embodiment, when the DASIM  200  is in the second configuration, the DASIM  200  may be configured so as to at least partially allow fluid communication between the interior of the DASIM  200  (e.g., an axial flow bore) and the exterior of the DASIM  200 . In an embodiment, as is disclosed herein, the DASIM  200  may be configured to transition between the second configuration and a third configuration upon further actuation (e.g., via the AST  300 ) of the ratchet mechanism  250  in the first direction, as will be disclosed herein. Additionally, the DASIM  200  may be configured to transition from the second configuration to the first configuration upon actuation (e.g., via the AST  300 ) of a ratchet mechanism  250  in a second direction. 
     Referring to  FIGS. 4A-4B , an embodiment of a DASIM  200  is illustrated in a third configuration. In an embodiment, when the DASIM  200  is in the third configuration, the DASIM  200  may be configured so as to allow fluid communication at a maximum flow rate between the interior of the DASIM  200  (e.g., an axial flow bore) and the exterior of the DASIM  200 . In an embodiment, as is disclosed herein, the DASIM  200  may be configured to transition from the third configuration to the second configuration upon actuation (e.g., via the AST  300 ) of the ratchet mechanism  250  in the second direction, as will be disclosed herein. 
     Referring to  FIGS. 2A-2B, 3A-3B, and 4A-4B , in an embodiment the DASIM  200  generally comprises a housing  210 , an inner mandrel  220 , a valve sleeve  214 , and the ratchet mechanism  250 . While an embodiment of the DASIM  200  is disclosed with respect to  FIGS. 2A-2B, 3A-3B, and 4A-4B , one of ordinary skill in the art upon viewing this disclosure, will recognize suitable alternative configurations. As such, while embodiments, of a DASIM may be disclosed with reference to a given configuration (e.g., DASIM  200  as will be disclosed with respect to  FIGS. 2A-2B, 3A-3B, and 4A-4B ), this disclosure should not be construed as limited to such embodiments. 
     In an embodiment, the housing  210  may be characterized as a generally tubular body having a first terminal end  210   a  (e.g., an up-hole end) and a second terminal end  210   b  (e.g., a down-hole end), for example, as illustrated in  FIGS. 2A-2B, 3A-3B, and 4A-4B . The housing  210  may be characterized as generally defining a longitudinal axial flow bore  248 . In an embodiment, the housing  210  may be configured for connection to and/or incorporation within a tubular string (e.g., the tubular string  112  as shown in  FIG. 1 ), for example, the housing  210  may comprise a suitable means of connection to the tubular string  112 . For instance, the first terminal end  210   a  of the housing  210  may comprise internally and/or externally threaded surfaces as may be suitably employed in making a threaded connection to the tubular string  112 . In an additional or alternative embodiment, the second terminal end  210   b  of the housing  210  may also comprise internally and/or externally threaded surfaces as may be suitably employed in making a threaded connection to the tubular string  112 . Alternatively, a DASIM like DASIM  200  may be incorporated with a tubular string like tubular string  112  via any suitable connection, such as, for example, via one or more quick-connector type connections. Suitable connections to a tubular string member will be known to those of ordinary skill in the art viewing this disclosure. 
     In an embodiment, the housing  210  may be configured to support one or more sleeves (e.g., the inner mandrel  220 ), as will be disclosed herein. For example, the housing  210  may comprise a first cylindrical bore surface  228  proximate to the first terminal end  210   a  (e.g., an uphole end), a second cylindrical bore surface  236 , a third cylindrical bore surface  240  proximate to the second terminal end  210   b  (e.g., a downhole end), a fourth cylindrical bore surface  230  spanning between the first cylindrical bore surface  228  and the second cylindrical bore surface  236 , and a fifth cylindrical bore surface spanning between the second cylindrical bore surface  236  and the third cylindrical bore surface  238 . In an embodiment, the fourth cylindrical bore surface  230  and/or the fifth cylindrical bore surface  232  may be generally characterized as having a diameter greater than the diameter of the first cylindrical bore surface  228 , the second cylindrical bore surface  236 , and the third cylindrical bore surface  238 . 
     Additionally, in an embodiment, the housing  210  comprises one or more ports  212  configured to provide a route of fluid communication between the axial flow bore  248  of the DASIM  200  and the exterior of the DASIM  200 , when so-configured. For example, in the embodiments of  FIGS. 2A-2B, 3A-3B, and 4A-4B , the housing  210  comprises the ports  212  which may be suitable sized (e.g., port diameter), for example, to control and/or allow a desired and/or predetermined fluid flow-rate. Additionally or alternatively, the ports  212  may further comprise a nozzle, a valve, a cover, a screen, a fluidic diode, any other suitable flow-rate and/or pressure altering component as would be appreciated by one of ordinary skill in the art upon viewing this disclosure, or combination thereof. 
     In an embodiment, the inner mandrel  220  may be characterized as a generally tubular body having a first mandrel terminal end  220   a  (e.g., an up-hole end) and a second mandrel terminal end  220   b  (e.g., a down-hole end), for example, as illustrated in  FIGS. 2A-2B, 3A-3B, and 4A-4B . The inner mandrel  220  may be characterized as generally defining a longitudinal axial flow bore, for example, such that a fluid communicated via the axial flow bore  248  of the housing  210  will flow into and through the axial flow bore of the inner mandrel  220 . In an embodiment, the inner mandrel  220  may comprise a first outer cylindrical surface  226  extending from the first mandrel terminal end  220   a  (e.g., an uphole end), a third outer cylindrical bore surface  240  extending from the second mandrel terminal end  220   b  (e.g., an down-hole end), and a second outer cylindrical bore surface  234  spanning between the first outer cylindrical surface  226  and the third outer cylindrical surface  240 . In such an embodiment, the first outer cylindrical surface  226  and the fourth cylindrical bore surface  230  may form a first annular region  216 , for example, spanning between the first cylindrical bore surface  228  and the second cylindrical bore surface  236 . Additionally, the fifth cylindrical bore surface  232  and the second outer cylindrical bore surface  234  and/or the third outer cylindrical bore surface  240  may form a second annular region  218 , for example, spanning between the second cylindrical bore surface  236  and the third cylindrical bore surface  238 . In such an embodiment, the DASIM  200  may be configured such that a fluid (e.g., an aqueous fluid) may be communicated from the axial flow bore  248  to the first annular region  216  to the second annular region  218  and may exit the DASIM  200  via the ports  212 . Additionally, the inner mandrel  220  may be configured for connection to and/or incorporation within the housing  210 , for example, the inner mandrel  220  may comprise a suitable means of connection to the housing  210 . For instance, the first outer cylindrical surface  226  of the inner mandrel  220  may comprise an at least partially threaded surface as may be suitably employed in making a threaded connection to an interior portion of the housing  210  (e.g., the first cylindrical bore surface  228 ). In an additional or alternative embodiment, the third cylindrical bore surface  240  of the inner mandrel may also comprise an at least partially externally threaded surface as may be suitably employed in making a threaded connection to an interior portion of the housing  210  (e.g., the third cylindrical bore surface  238 ). 
     In an embodiment, as illustrated in  FIGS. 2A-2B, 3A-3B, and 4A-4B , the inner mandrel  220  comprises a helical slot, groove, pathway, or the like along the interior and/or exterior of the inner mandrel  220 . For example, the helical slot  222  may be configured to provide a pathway or guide for one or more wellbore servicing tools (e.g., the AST  300 ), as will be disclosed herein. In such an embodiment, the helical slot  222  may form a rotating pathway between the first terminal mandrel end  220   a  and the second terminal mandrel end  220   b  about or greater than 360 degrees about the inner mandrel, for example, about 540 degrees, about 720 degrees, about 900 degrees, etc. For example, the helical slot  222  may form inclined planes (e.g., about 45 degree planes) along the inner mandrel  220 . Additionally, at least a portion of the helical slot  222  may further comprise a ported cover  224  comprising a plurality of holes, perforations, ports, or the like. For example, the ported cover  224  may be configured to provide a route of fluid communication between the axial flow bore of the inner mandrel  220  and the exterior (e.g., the first annular region  216 ) of the inner mandrel  220 , for example, a route of fluid communication for condensation formed during a wellbore servicing operation, as will be disclosed herein. For example, the DASIM  200  may be configured such that condensation and/or moisture formed along the inner mandrel  220  during a wellbore servicing operation (e.g., steam injection) may be reintroduced to the wellbore servicing operation to be utilized via the ported cover  224 . 
     Additionally, the helical slot  222  may further comprise a decision path, a “Y” path, a branch, or the like. For example, a terminal end (e.g., a downhole end) of the helical slot  222  may comprise a decision path and may be configured to provide a plurality of pathways along the helical slot  222 . In such an instance, the helical slot  222  may be configured to guide a wellbore servicing tool (e.g., the AST  300 ) along the any of the plurality of pathways, when so-configured. Additionally, in an embodiment, each of the pathways may be configured to allow and/or to engage a predetermined wellbore servicing tool and/or predetermined configuration of wellbore servicing tool, as will be disclosed herein. 
     In an embodiment, the valve sleeve  214  may be positionable and configureable to selectively allow, disallow, and/or partially disallow fluid communication from the DASIM  200  via the ports  212  and, thereby adjust the flow rate of the DASIM  200 . In an embodiment, the valve sleeve  214  may generally comprise a cylindrical or tubular structure having a cylindrical sleeve bore  242  generally defining an axial flow bore extending there-through. The valve sleeve  214  may comprise a unitary structure (e.g., a single solid piece). In an alternative embodiment, the valve sleeve  214  may comprise two or more segments, for example, two or more segments coupled together via one or more threaded connections. Alternatively, the two or more segments may be joined via any suitable methods as would be appreciated by one of ordinary skill in the art upon viewing this disclosure. 
     In an embodiment, the valve sleeve  214  may be positionable and concentrically positioned within the housing  210  (e.g., within the second annular region  218 ), for example, via the ratchet mechanism  250 , as will be disclosed. The valve sleeve  214  may be positionable (e.g., rotationally or slidably movable) with respect to the housing  210 , for example, via the ratchet mechanism  250 , as will be disclosed herein. In the embodiments of  FIGS. 2A-2B, 3A-3B, and 4A-4B , the valve sleeve  214  may be slidably fit against at least a portion of the fifth cylindrical bore surface  232  of the housing  210  and at least a portion of the second outer cylindrical surface  234  of the inner mandrel  220 . In an embodiment, one or more of the interfaces between the valve sleeve  214  and the housing  210  and/or the inner mandrel  220  may be fluid-tight and/or substantially fluid-tight. For example, the housing  210 , the valve sleeve  214 , and/or the inner mandrel  220  may comprise one or more suitable seals at such an interface, for example, for the purpose of prohibiting or restricting fluid movement via such an interface. Suitable seals include but are not limited to T-seals, an O-ring, a gasket, any other suitable seals as would be appreciated by one of ordinary skill in the art upon viewing this disclosure, or combinations thereof. 
     In such an embodiment, the valve sleeve  214  may be configured to transition from a first configuration to a second configuration and from the second configuration to a third configuration. Referring to the embodiment of  FIGS. 2A-2B , when the DASIM  200  is in first configuration, the valve sleeve  214  is in the first configuration. When the valve sleeve  214  is in the first configuration, the valve sleeve  214  is configured to substantially cover or block the ports  212  of the DASIM  200  and thereby prohibit and/or substantially prohibit fluid communication from the DASIM  200  via the ports  212 . Referring to the embodiment of  FIGS. 3A-3B , when the DASIM  200  is in second configuration, the valve sleeve  214  is in the second configuration. When the valve sleeve  214  is in the second configuration, the valve sleeve  214  is configured to partially cover or block the ports  212  of the DASIM  200  and thereby partially prohibit fluid communication from the DASIM  200  via the ports  212 . Referring to the embodiment of  FIGS. 4A-4B , when the DASIM  200  is in third configuration, the valve sleeve  214  is in the third configuration. When the valve sleeve  214  is in the third configuration, the valve sleeve  214  is configured to not cover or block the ports  212  of the DASIM  200  and thereby substantially allows fluid communication from the DASIM  200  via the ports  212 . 
     In an additional or alternative embodiment, a flow path formed between the fifth cylindrical bore surface  232  and a valve sleeve contact surface  264  may act as a fluid choke or restriction. For example, in the embodiments of  FIGS. 2A-2B , the flow path may be sealed (e.g., via the fluid choke) to substantially prevent fluid flow. Additionally, the fluid choke may be widened to allow a greater fluid flow. 
     In an embodiment, the ratchet mechanism  250  may be configured to adjust the fluid flow rate of the DASIM  200 , for example, via positioning or configuring the valve sleeve  214 , as will be disclosed herein. In the embodiment of  2 A- 2 B,  3 A- 3 B, and  4 A- 4 B, the ratchet mechanism  250  may be disposed within the inner mandrel  220  of the DASIM  200 , for example, within a down-hole portion of the DASIM  200 . Referring to the embodiment of  FIGS. 5 and 6 , the ratchet mechanism  250  comprises a plurality of continuous profiles. In an embodiment, the continuous profiles may generally define a continuous edge or profile (e.g., a continuous profile comprising a plurality of ratchet teeth) of one more portions of the ratchet mechanism  250 , as will be disclosed herein. For example, the ratchet mechanism  250  comprises a first continuous profile  258  along an edge (e.g., a downhole facing edge) of a first ratchet portion  252 , a second continuous profile  260  along an edge (e.g., an uphole facing edge) of a second ratchet portion  254 , a third continuous profile  262  along an edge (e.g., a downhole facing edge) of the second ratchet portion  254 , and a fourth continuous profile  264  along an edge (e.g., an uphole facing edge) of a third ratchet portion  256 . Additionally, the first continuous profile  258  and the second continuous profile  260  may form a first continuous slot  270  (e.g., continuous J-slots, control grooves, indexing slots, etc.) and the third continuous profile  262  and the fourth continuous profile  264  may form a second continuous slot  272 . As used herein, a continuous slot refers to a slot extending entirely about (e.g., 360 degrees) the circumference of the ratchet mechanism  250 . A continuous profile refers to a design in which several lug positions are possible corresponding to a rotational position of the ratchet mechanism  250 . 
     Additionally, the ratchet mechanism  250  may be configured to engage a lug (e.g., a selector key  314 , as will be disclosed), for example, via the first continuous profile  258 , the second continuous profile  260 , the third continuous profile  262 , and/or the fourth continuous profile  264 . In an embodiment, the ratchet mechanism  250  is configured to rotate in response to a force applied by the engagement between the lug (e.g., the selector key  314 ) and the ratchet mechanism  250 . For example, the ratchet mechanism  250  may be configured to rotate due to the angled edge interface between the selector key  314  and the first continuous profile  258 , the second continuous profile  260 , the third continuous profile  262 , and/or the fourth continuous profile  264 . Additionally, the ratchet mechanism  250  may be configured such that a complete cycle (e.g., raising and lowering, or lowering and raising) of the selector key  314  results in partial or complete rotation of the ratchet mechanism  250 . In an embodiment, the ratchet mechanism  250  may be configured such that a complete cycle of a selector key  314  between the first continuous profile  258  and the second continuous profile  260  (e.g., within the first continuous slot  270 ) causes the ratchet mechanism  250  to rotate in a first direction (e.g., clock-wise or counter-clockwise), as illustrated in  FIG. 5 . Additionally, the ratchet mechanism  250  may be configured such that a complete cycle of a selector key  314  between the third continuous profile  262  and the fourth continuous profile  256  (e.g., within the second continuous slot  272 ) causes the ratchet mechanism  250  to rotate in a second direction (e.g., clock-wise or counter-clockwise), as illustrated in  FIG. 6 . In an embodiment, the ratchet mechanism  250  may be configured to rotate in the first direction or the second direction until the DASIM  200  transitions to a desired configuration (e.g., to the first configuration or the third configuration, or any point in between). Additionally, the number of teeth of the continuous slots may determine the amount of rotation provided by each cycling the ratchet mechanism  250 . As such, the amount of rotation provided by each cycling the ratchet mechanism  250  may allow the amount of travel of the valve sleeve  214  to be controlled. 
     In an embodiment, the ratchet mechanism  250  is coupled to and/or joined with the valve sleeve  214  and is configured to position and/or move the valve sleeve  214  longitudinally with respect to the housing  210 . For example, in an embodiment, the ratchet mechanism  250  and the valve sleeve  214  may be joined or coupled via a threaded connection or interface (e.g., threads  280 ). In such an embodiment, the ratchet mechanism  250  may be configured to rotate (e.g., clock-wise or counter clock-wise) the threaded interface about the longitudinal axis of the axial flow bore. Additionally, the rotational movement of the ratchet mechanism  250  (e.g., the threaded interface) may induce a longitudinal movement or translation of the valve sleeve  214  with respect to the housing  210 . For example, the thread pitch of the threaded interface may determine the amount of rotation provided by each cycling the ratchet mechanism  250  and thereby controls the amount of travel of the valve sleeve  214 . As such, the resolution of linear travel may be determined by the number of teeth along one or more continuous profiles (e.g., the first continuous profile  258 , the second continuous profile  260 , the third continuous profile  262 , and/or the fourth continuous profile  264 ) and/or the thread pitch of the threads  280 . 
     In an embodiment, the ratchet mechanism  250  may be configured such that the full range of rotation of the ratchet mechanism  250  provides a predetermined linear travel of the valve sleeve  214 , for example, about 2 inches (in), about 2.5 in, about 2.815 in, about 6 in, about 1 foot (ft), or any other suitable travel distance as would be appreciated by one of ordinary skill in the art upon viewing this disclosure. As such, the total travel may be limited by the length of a slot  282  and one or more pins  283 . Additionally, the ratchet mechanism  250  may be configured such that each partial revolution provides partial linear movement or travel, for example, a 1/12 th  revolution may provide a linear travel of about 0.0833 in. In an alternative embodiment, the ratchet mechanism  250  and the valve sleeve  214  may be joined and/or coupled via any other suitable method as would be appreciated by one of ordinary skill in the art upon viewing this disclosure. 
     In an embodiment, the AST  300  may be generally configured to selectively actuate or transition the DASIM  200  between the first configuration, the second configuration, and the third configuration, or any point in between.

     Referring to  FIG. 10 , an embodiment of an AST  300  is illustrated in a fourth configuration. In an embodiment, when the AST  300  is in the fourth configuration, the AST  300  may be configured such that, the first housing portion  302  is in the second position with respect to the second housing portion  312 , the locking pin  310  is in the extended position, the floating catch  306  is in the retracted position, the selector key  314  is in the retracted position, the sliding collar  320  is in the second position with respect to the third housing portion  304 , and the sliding catch  324  is in the third position with respect to the third housing portion  304 . 
     In an embodiment, a wellbore servicing method utilizing a DASIM and/or a system comprising a DASIM is disclosed herein. In an embodiment, as illustrated in  FIG. 11 , the wellbore servicing method  400  may generally comprise the steps of providing a DASIM (e.g., a DASIM  200 )  402 , providing an AST (e.g., an AST  300 )  404 , adjusting the DASIM tool  406 , and communicating a fluid via the DASIM  408 . 
     Returning to  FIG. 1 , when providing a DASIM  402 , one or more DASIMs, such as DASIM  200 , may be provided and each DASIM  200  may be preconfigured to provide a desired fluid flow rate. In an embodiment, each DASIM  200  may be adjusted at the surface prior to integration with a tubular string  112  and/or prior to installation within a wellbore  114 . For example, one or more DASIMs  200  may be adjusted to the first configuration, the second configuration, and/or the third configuration. In an embodiment, the one or more DASIMs  200  may be incorporated with the tubular string  112  and may be disposed and/or positioned to a desired depth within the wellbore  114 . Additionally, providing the DASIM  402 , may comprise isolating one or more adjacent zones and/or securing the tubular string  112  (e.g., within the wellbore  114 ) at a given or desired depth within the wellbore  114 . For example, one or more packers  124  may be employed to couple and/or secure the tubular string  112  within the wellbore  114  and/or to isolate one or more DASIMs  200 . 
     In an embodiment, when providing an AST  404 , an AST, such as AST  300 , may be provided in the first configuration. In such an embodiment, the AST  300  may comprise the required selector key  314  for a given operation. For example, the AST  300  may comprise an appropriate selector key  314  to actuate (e.g., to open or to close) a DASIM  200 . In such an embodiment, the AST  300  may be coupled work a work string  301  and may be introduced to and/or conveyed downwardly (e.g., down-hole) through the axial flow bore  126  of the tubular string  112 . 
     In an embodiment, adjusting the DASIM  406 , may comprise the steps of transitioning the AST  300  from the first configuration to the second configuration, transitioning the AST  300  from the second configuration to the third configuration, actuating the DASIM  200 , and transitioning the AST  300  from the third configuration to the fourth configuration. 
     In an embodiment, as the AST  300  is conveyed downward through the axial flow bore  126  of the tubular string  112 , one or more surfaces of the AST  300  may engage the interior surface of the tubular string  112  and thereby transition the AST  300  from the first configuration to the second configuration. For example, the floating catch  306  may engage the interior surface of the tubular string  112  and may transition from the expanded position to the retracted position. Additionally, the sliding catch  324  (e.g., the contact lip  348 ) may engage the interior surface of the tubular string  112  and may transition from the first position to the second position with respect to the third housing portion  304 . 
     In an embodiment, the AST  300  may be conveyed to a depth below (e.g., below the second terminal end  210   b  of the DASIM  200 ) the desired DASIM  200  to be adjusted and/or actuated. Following reaching a depth below the desired DASIM  200  to be actuated, the AST  300  may then be conveyed (e.g., pulled) in an upward (e.g., up-hole) direction. When the AST  300  is conveyed in an upward direction, one or more surfaces of the AST  300  may engage the interior surface of the tubular string  112  and thereby transition the AST  300  from the second configuration to the third configuration. For example, the sliding catch  324  (e.g., the contact lip  348 ) may engage the interior surface (e.g., a downward facing contact surface  210   c ) of the tubular string  112  and may transition from the second position to the third position with respect to the third housing portion  304 . Additionally, transitioning the sliding catch  324  from the second position to the third position with respect to the third housing portion  304  and may apply a force onto the sliding collar  320  (e.g., via the spring  322 ) in the direction of the second position with respect to third housing portion  304  and thereby transition the sliding collar  320  from the first position to the second position with respect to the third housing portion  304 . Further, transitioning the sliding collar  320  from the first position to the second position with respect to the third housing portion  304  may configure the retaining catch lip  318  of the sliding collar  320  to no longer retain the selector key  314  and thereby releases the selector key  314  and transitions the selector key  314  from the retracted position to the expanded position. 
     Following transitioning the AST  300  to the third configuration, the AST  300  may be conveyed downwardly through the axial flow bore  248  of the DASIM  200 . Referring to the embodiment of  FIG. 12 , as the AST  300  is conveyed downward through the axial flow bore  248  of the DASIM  200 , the selector key  314  may engage the helical slot  222  of the inner mandrel  220 . In such an embodiment, the selector key  314  (e.g., the engagement portion  330 ) may be confined within the helical slot  222  and the helical slot  222  may guide the selector key  314  as the AST  300  conveyed downwardly. As such, the selector  314  may comprise a suitable profile to be guided to the ratchet mechanism  250  via one of the decision paths (e.g., decision path  222   a  or decision path  222   b ) of the helical slot  222  and thereby engages the ratchet mechanism  250 . In an embodiment, the decision paths (e.g., decision path  222   a  or decision path  222   b ) may each provide a guided path having a different width. For example, the decision path  222   a  may be generally defined as having a guide path wider than the decision path  222   b . As such, the selector key  314  may be sized such that the selector key  314  follow the decision path  222   a  (e.g., to the first continuous slot  270 ) and unable to enter and/or follow decision path  222   b  (e.g., to the second continuous slot  272 ). 
     Upon the engagement of the selector key  314  and the ratchet mechanism  250 , the AST  300  may actuate the ratchet mechanism  250 , for example, for the purpose of adjusting the flow rate of the DASIM  200  (e.g., via opening or closing the ports  212  of the DASIM  200 ). For example, the AST  300  may oscillate between moving in an upwardly direction (e.g., an up-hole direction) and a downwardly direction (e.g., a down-hole direction) such that the selector key  314  oscillates within one of the continuous slots (e.g., the first continuous slot  270  or the second continuous slot  272 ). In such an embodiment, the selector key  314  may engage the continuous slots and may apply a sufficient force to actuate (e.g., to rotate) the ratchet mechanism  250  in the first direction or the second direction. For example, the AST  300  may actuate the ratchet mechanism  250  to rotate one or more partial or complete cycles or revolutions. As such, actuation of the ratchet mechanism  250  may cause the DASIM  200  to rotate in the second direction to transition towards the first configuration (e.g., a more restrictive configuration) or to rotate in the first direction to transition towards the third configuration (e.g., a less restrictive configuration). In an embodiment, the AST  300  may actuate the DASIM  200  until configuring the DASIM  200  to provide a desired resistance to fluid flow. 
     In an embodiment, upon adjusting the DASIM  200  to a desired setting, the AST  300  may be removed from the DASIM  200  and/or the wellbore  114 . In an embodiment, the AST  300  may be pulled in an upwardly (e.g., up-hole) direction with a sufficient force to move the first housing portion  302  in the direction of the second position with respect to the second housing portion  312  and thereby transition the first housing portion  302  to the second position with respect to the second housing portion  312 . For example, the selector key  314  (e.g., the engagement portion  330 ) may engage a continuous profile of the ratchet mechanism  250  and may generate a lateral tension (e.g., a stretching force) along the longitudinal axis  500  of the AST  300 . In such an embodiment, upon transitioning the first housing portion  302  to the second position with respect to the second housing portion  312 , the first housing portion  302  may transition the selector key  314  from the extended position to the retracted position, as previously disclosed. Additionally, upon transitioning the first housing portion  302  to the second position with respect to the second housing portion  312 , the locking pin  310  may engage the locking pin bore  308  and thereby transition the locking pin  310  from the retracted position to the extended position. In such an embodiment, the first housing portion  302  the engagement of the locking pin  310  and the locking pin bore  308  may retain the first housing portion  302  in the second position with respect to the second housing portion  312  and thereby transitions the AST  300  from the third configuration to the fourth configuration. Upon transitioning the AST  300  to the fourth configuration, the AST  300  may be retracted (e.g., pulled) through the axial flow bore  126  of the tubular string  112  to the surface  104 . 
     In an embodiment, one or more additional DASIM  200  may be adjusted. For example, upon retrieving the AST  300  from the wellbore  114 , the AST  300  may be transitioned from the fourth configuration to the first configuration. In an embodiment, the locking pin  310  may be transitioned from the extracted position to the retracted position, for example, via an application of force onto the locking pin  310  in the direction of the retracted position via the locking pin bore  308 . In such an embodiment, upon the transitioning of the locking pin  310  to the retracted position, the first housing portion  320  may transition to the first position with respect to the second housing portion  312 . Additionally, the selector key  314  may be interchanged to achieve the desired effect for the subsequent DASIM. The selector key  314  may be transitioned from the extracted position to the retracted position, for example, via an application of force onto the selector key  314  in the direction of the retracted position, and the sliding catch  324  may also be transitioned from the third position to the first position with respect to the third housing portion  304 . In such an embodiment, the sliding collar  320  may transition to the first position with respect to the third housing portion  304  in response to transition the sliding catch  324  from the third position to the first position with respect to the third housing portion  304  and thereby may configure the AST  300  to retain the selector key  314  in the retracted position, for example, via the engagement of the retaining lip  316  and the retaining lip catch  318 , as previously disclosed. As such, the AST  300  may be configured in the first configuration for one or more additional wellbore servicing operations (e.g., actuating one or more DASIMs). 
     Additionally, in an embodiment the AST  300  may be reintroduced into the wellbore  114  and/or the tubular string  112  and may engage and actuate a DASIM using methods similar to those previously disclosed. For example, the AST  300  may transition from the first configuration to the second configuration while being conveyed through the tubular string  112 , transition from the second configuration to the third configuration to actuate the DASIM, and transition from the third configuration to the fourth configuration to return to the surface. As such, the AST  300  may be employed to adjust and/or configure any number of DASIM, as will be appreciated by one of ordinary skill in the art upon viewing this disclosure. 
     In an embodiment, when communicating a fluid via the DASIM  408 , upon configuring the one or more DASIMs  200  to a desired fluid flow rate, the wellbore servicing operation may further comprise communicating a wellbore servicing fluid, for example, for the purposes of performing a formation stimulation operation via one or more wellbore servicing tools (e.g., DASIM  200 ) incorporated within the tubular string. For example, a fluid (e.g., water, steam, etc.) may be introduced at a desired pressure to the axial flow bore  126  of the tubular string  112 , for example, via one or more pumps located at the surface  104 . As such, the fluid will be communicated via the tubular string  112  and released into one or more zones of the subterranean formation  102  via one or more DASIMs  200 . Additionally, condensation and/or moisture formed during such a wellbore servicing operation may be captured (e.g., via the ported cover  224  of the inner mandrel  220 ) and utilized (e.g., communicated to the subterranean formation  102 ) by the DASIM  200 . 
     In an embodiment, a DASIM  200 , a system comprising a DASIM  200 , and/or a wellbore servicing method employing such a system and/or a DASIM  200 , as disclosed herein or in some portion thereof, may be advantageously employed to provide an adjustable fluid flow rate and to improve wellbore servicing operation efficiency. For example, in an embodiment, a DASIM like DASIM  200  enables a wellbore servicing system to provide an adjustable fluid flow rate once installed (e.g., within a wellbore) for one or more wellbore servicing operations (e.g., wellbore stimulation). Conventional tools may not have to ability to provide a finely adjustable fluid flow rate once installed within a wellbore. Additionally, a DASIM  200  enables condensation formed during a wellbore servicing operation, for example, a steam injection operation, to be utilized during the wellbore servicing operation. Conventional tools may be unable to capture and/or to utilize condensation formed during a steam injection operation which may lead to inefficiency and water deposits within a wellbore and/or thermal gradients along a wellbore. Therefore, the methods disclosed herein provide a means by which to adjust selectively adjust a fluid flowrate of a down-hole wellbore servicing tool and to improve a wellbore servicing operation by capturing and/or utilizing condensation formed during the wellbore servicing operation.
