Title: Dried shale inhibitor additives

Description:
BACKGROUND 
     The present disclosure relates to methods and compositions for using shale inhibitor additives in subterranean formations. 
     Treatment fluids are used in a variety of operations that may be performed in subterranean formations. As referred to herein, the term “treatment fluid” will be understood to mean any fluid that may be used in a subterranean application in conjunction with a desired function and/or for a desired purpose. The term “treatment fluid” does not imply any particular action by the fluid. Treatment fluids often are used in, e.g., well drilling, completion, and stimulation operations. Examples of such treatment fluids include, among others, drilling fluids, well cleanup fluids, workover fluids, conformance fluids, gravel pack fluids, acidizing fluids, fracturing fluids, spacer fluids, and the like. 
     During drilling of subterranean wellbores, various strata that include reactive shales may be encountered. The term “shale” may refer to materials that may “swell,” or increase in volume, when exposed to water. Examples of these shales may include certain types of clays (e.g., bentonite). Reactive shales may be problematic during drilling operations because of, among other factors, their tendency to degrade when exposed to aqueous media such as aqueous-based drilling fluids. This degradation, of which swelling is one example, can result in undesirable drilling conditions and/or undesirable interference with the drilling fluid. For instance, the degradation of the shale may interfere with attempts to maintain the integrity of drilled cuttings traveling up the wellbore until such time as the cuttings can be removed by solids control equipment located at the surface. 
     One technique used to counteract the propensity of aqueous drilling fluids to interact with reactive shales in a formation involves the use of certain additives in aqueous drilling fluids that may inhibit shale, e.g., additives that may demonstrate a propensity for reducing the tendency of shale to absorb water. Liquid shale inhibitor additives have been used to inhibit shale, but, in certain cases, may be difficult to handle.

     DESCRIPTION OF CERTAIN EMBODIMENTS 
     Illustrative embodiments of the present disclosure are described in detail herein. In the interest of clarity, not all features of an actual implementation may be described in this specification. It will of course be appreciated that in the development of any such actual embodiment, numerous implementation-specific decisions may be made to achieve the specific implementation goals, which may vary from one implementation to another. Moreover, it will be appreciated that such a development effort might be complex and time-consuming, but would nevertheless be a routine undertaking for those of ordinary skill in the art having the benefit of the present disclosure. 
     The present disclosure relates to methods and compositions for using shale inhibitor additives in subterranean formations, and specifically, to dried shale inhibitor additives and methods for use. More specifically, in certain embodiments, the methods of the present disclosure include providing a dried shale inhibitor additive that includes a precipitate of at least one liquid amine shale inhibitor, allowing at least a portion of the dried shale inhibitor additive to dissolve in a treatment fluid including an aqueous base fluid, and introducing the treatment fluid into a wellbore penetrating at least a portion of a subterranean formation. In some embodiments, the methods of the present disclosure include providing at least one liquid amine shale inhibitor, mixing the at least one liquid amine shale inhibitor with a solvent in which the at least one liquid shale inhibitor is substantially or entirely insoluble to produce a precipitate, and drying the precipitate to produce a dried shale inhibitor additive. In some embodiments, the compositions of the present disclosure include a dried shale inhibitor additive including a precipitate of at least one liquid amine shale inhibitor. 
     Among the many potential advantages to the methods and compositions of the present disclosure, only some of which are alluded to herein, the methods and compositions of the present disclosure may provide a dried shale inhibitor additive that may be easier to handle than certain liquid shale inhibitor additives, which may require additional equipment (e.g., drums). In certain embodiments, the methods and compositions of the present disclosure may provide a dried shale inhibitor additive that has reduced shipping weight and/or cost, reduced volume and/or product footprint at the rig, reduced storage space, reduced packing cost, and reduced potential for liquid leaks as compared to certain liquid shale inhibitor additives. In certain embodiments, the methods and compositions of the present disclosure may provide a dried shale inhibitor additive that has a reduced water weight as compared to certain liquid shale inhibitor additives. In certain embodiments, the methods and compositions of the present disclosure may provide a dried shale inhibitor additive that is more potent weight for weight as compared to certain liquid shale inhibitor additives. In certain embodiments, the methods and compositions of the present disclosure may provide substantially or entirely salt-free dried shale inhibitor additives. In certain embodiments, the methods and compositions of the present disclosure may provide a dried shale inhibitor additive that is manufactured more sustainably than certain shale inhibitor additives, due in part to that the solvent may be reused. In certain embodiments, the methods and compositions of the present disclosure may provide a homogenous liquid composite that may be precipitated to produce a dried shale inhibitor additive that is more homogenous than a dry powder blend (e.g., a dry mix composition produced by mixing at least two dry mix components). 
     The dried shale inhibitor additive of the present disclosure may include at least one shale inhibitor. The shale inhibitors of the present disclosure may act to inhibit shale by any mechanism, whether known or unknown. In certain embodiments, the shale inhibitor may be an amine shale inhibitor. In some embodiments, the amine shale inhibitor may include at least one amine. The amine may be a primary amine, a secondary amine, a tertiary amine, a quaternary amine, a neutral species of the forgoing, a protonated species of the forgoing along with a counter anion to balance charge, a derivative of the foregoing, and any combination thereof. 
     The dried shale inhibitor additive of the present disclosure may be prepared by drying a liquid shale inhibitor (e.g., a liquid amine shale inhibitor). The liquid shale inhibitor may be an aqueous liquid shale inhibitor. 
     The dried shale inhibitor additive of the present disclosure may include a precipitate of a liquid shale inhibitor (e.g., a liquid amine shale inhibitor). In some embodiments, the dried shale inhibitor additive may be produced by a method including precipitating the liquid shale inhibitor (e.g., the liquid amine shale inhibitor). In certain embodiments, the liquid shale inhibitor may be precipitated using a solvent in which the liquid shale inhibitor is substantially or entirely insoluble. In certain embodiments, the liquid shale inhibitor may be precipitated using a solvent that is a poor solvent for the shale inhibitor. A poor solvent may be a solvent in which interactions between shale inhibitor molecules are more energetically favorable than interactions between solvent molecules and shale inhibitor molecules. In some embodiments, the liquid shale inhibitor (e.g., a liquid amine shale inhibitor) may be mixed with the solvent to produce the precipitate of the liquid shale inhibitor. The solvent used to precipitate the shale inhibitor of the present disclosure may be miscible with water. In some embodiments, a miscible mixture of the solvent and water (e.g., water from the liquid amine shale inhibitor) may create a homogenous solvent blend that the shale inhibitor is substantially or entirely insoluble in, thus causing the precipitation to occur. 
     Examples of solvents that may precipitate the liquid shale inhibitor include, but are not limited to, acetone, isopropyl alcohol, methanol, ethanol, propanol and propanol isomers, butanol and butanol isomers, dichloromethane, tetrahydrofuran, ethyl acetate, acetonitrile, dimethylformamide, dimethyl sulfoxide, hexamethylphosphoramide, propylene carbonate, ethyl lactate, ethylene glycol, diethylene glycol, propylene glycol, and any combination thereof. In certain embodiments, the solvent may be screened to determine if it is a suitable solvent to precipitate a particular liquid shale inhibitor. In certain embodiments, the solvent is added to an aqueous solution including the liquid shale inhibitor in an amount sufficient to cause at least a portion of the liquid shale inhibitor to precipitate. A person skilled in the art, with the benefit of this disclosure, will recognize how to screen for a solvent in which the liquid shale inhibitor is substantially or entirely insoluble that may be included in the methods and compositions of the present disclosure. 
     In certain embodiments, the solvent may be easily dryable. In some embodiments, the solvent may not react with the shale inhibitor. In some embodiments, at least a portion of the solvent may be separated from the aqueous solution and recovered. In some embodiments, at least a portion of the recovered solvent may be reused to precipitate additional liquid shale inhibitor. 
     In certain embodiments, the precipitate of the liquid shale inhibitor may be collected (e.g., by filtration) and dried (e.g., using a vacuum pump) to produce the dried shale inhibitor additive. The dried shale inhibitor additive may be sacked and used as a dry, free flowing shale inhibitor product for use in, e.g., a drilling fluid or drill-in fluid. 
     The dried shale inhibitor additive of the present disclosure may include two or more components. In certain embodiments, the dried shale inhibitor additive may include two or more shale inhibitors (e.g., amine shale inhibitors). In some embodiments, the dried shale inhibitor additive may be produced by precipitating at least two shale inhibitors (e.g., amine shale inhibitors) to produce a precipitate. 
     In certain embodiments, the dried shale inhibitor additive of the present disclosure may include a precipitate of a homogenous liquid composite. In certain embodiments, the dried shale inhibitor additive may be produced by a method including precipitating the homogenous liquid composite. In certain embodiments, the homogenous liquid composite may include an aqueous liquid mixture. In certain embodiments, the aqueous liquid mixture may include at least two liquid shale inhibitors (e.g., at least two amine shale inhibitors). In some embodiments, the aqueous liquid mixture may include at least one liquid shale inhibitor (e.g., a liquid amine shale inhibitor) and at least one liquid additive. In certain embodiments, the aqueous liquid mixture may include at least one liquid shale inhibitor and at least one solid additive dissolved in the aqueous liquid mixture. In some embodiments, the solid additive may be a solid shale inhibitor. In certain embodiments, the components of the aqueous liquid mixture may be liquid blended. The homogenous liquid composite may be precipitated using a solvent in which the homogenous liquid composite is substantially or entirely insoluble to produce the precipitate. In certain embodiments, the precipitate may be collected (e.g., by filtration) and dried (e.g., using a vacuum pump) to produce the dried shale inhibitor additive. Producing the dried shale inhibitor additive by a method including precipitating the homogenous liquid composite may result in a shale inhibitor additive that is more homogenous than a dry powder blend (e.g., a dry mix composition produced by mixing at least two dry mix components). 
     In some embodiments, the dried shale inhibitor additive may be a solid. In some embodiments, the dried shale inhibitor additive may be a solid powder. In some embodiments, the dried shale inhibitor additive may be further incorporated into a multi-component dry powder blend (e.g., a dry mix composition) that may include other components such as a lost circulation material and additional solid additives. 
     In certain embodiments, the dried shale inhibitor additive of the present disclosure may include particles of various sizes. In certain embodiments, the dried shale inhibitor additive may include particles having an average particle diameter ranging from about 0.1 micron to about 500 microns, from about 0.1 micron to about 400 microns, or from about 0.1 microns to about 300 microns. In certain embodiments, the dried shale inhibitor additive may include particles having a diameter of 500 microns or smaller, 400 microns or smaller, or 300 microns or smaller. In some embodiments, the dried shale inhibitor additive may include particles having a diameter of from about 0.1 micron to about 500 microns. In certain embodiments, the dried shale inhibitor additive may include particles that exhibit a particle size distribution between about 0.1 micron and about 2,000 microns. For example, in some embodiments, the dried shale inhibitor additive may include particles that have a median (d50) particle size distribution of from about 2.5 microns to about 1,000 microns. In certain embodiments, the dried shale inhibitor additive may include particles that exhibit a d50 particle size distribution of 1,000 microns or smaller, 750 microns or smaller, 500 microns or smaller, 250 microns or smaller, 100 microns or smaller, or 50 microns or smaller. 
     In certain embodiments, the dried shale inhibitor additive of the present disclosure may have the same or greater potency as compared to an equivalent amount of a liquid shale inhibitor, as measured by weight. For example, the dried shale inhibitor additive may have at least a 5% increase, at least a 10% increase, at least a 20% increase, at least a 30% increase, at least a 40% increase, at least a 50% increase, at least a 60% increase, at least a 75% increase, at least a 100% increase, at least a 200% increase, at least a 300% increase, at least a 400% increase or at least a 500% increase in potency as compared to an equivalent amount of the liquid shale inhibitor, as measured by weight. In certain embodiments, the dried shale inhibitor additive and the liquid shale inhibitor may include the same shale inhibitor. 
     The dried shale inhibitor additive may be included in a treatment fluid including an aqueous base fluid. In certain embodiments, the treatment fluid may include one or more additional treatment additives in addition to the dried shale inhibitor additive. In certain embodiments, at least a portion of the dried shale inhibitor additive may dissolve in the treatment fluid. In certain embodiments, the dried shale inhibitor additive may be a solid powder that at least partially dissolves upon contact with the treatment fluid to produce a liquid shale inhibitor. 
     The treatment fluid of the present disclosure may include any base fluid known in the art, including an aqueous fluid, anon-aqueous fluid, or any combination thereof. The term “base fluid” refers to the major component of the fluid (as opposed to components dissolved and/or suspended therein), and does not indicate any particular condition or property of that fluid such as its mass, amount, pH, etc. Aqueous fluids that may be suitable for use in the methods and compositions of the present disclosure may include water from any source. Such aqueous fluids may include fresh water, salt water (e.g., water containing one or more salts dissolved therein), brine (e.g., saturated salt water), seawater, oil-in-water emulsions, or any combination thereof. The aqueous fluids may include one or more ionic species, such as those formed by salts dissolved in water. For example, seawater and/or produced water may include a variety of divalent cationic species dissolved therein. Examples of a non-aqueous fluid that may be suitable for use as a base fluid include, but are not limited to an oil, a hydrocarbon, an organic liquid, a mineral oil, a synthetic oil, an ester, or any combination thereof.

For example, in certain embodiments, a salt may be dissolved in a fluid to form a solution and mixed with the dried shale inhibitor additive to form a treatment fluid. In some embodiments, the treatment fluid may include one or more starches in liquid form. 
     In certain embodiments, the treatment fluid may include an additional solvent.

A person skilled in the art, with the benefit of this disclosure, will recognize the types of additives that may be included in the fluids of the present disclosure for a particular application. 
     The methods and compositions of the present disclosure may be used in a variety of applications. These include downhole applications (e.g., drilling, fracturing, completions, oil production), use in conduits, containers, and/or other portions of refining applications, gas separation towers/applications, pipeline treatments, water disposal and/or treatments, and sewage disposal and/or treatments. In certain embodiments, a treatment fluid may be introduced into a subterranean formation. In some embodiments, the treatment fluid may be introduced into a wellbore that penetrates a subterranean formation. In certain embodiments, a wellbore may be drilled and the treatment fluid may be circulated in the wellbore during, before, or after the drilling. In some embodiments, the treatment fluid may be introduced at a pressure sufficient to create or enhance one or more fractures within the subterranean formation (e.g., hydraulic fracturing). 
     The methods and compositions of the present disclosure may directly or indirectly affect one or more components or pieces of equipment associated with the preparation, delivery, recapture, recycling, reuse, and/or disposal of the compositions of the present disclosure. For example, the methods and compositions may directly or indirectly affect one or more mixers, related mixing equipment, mud pits, storage facilities or units, composition separators, heat exchangers, sensors, gauges, pumps, compressors, and the like used generate, store, monitor, regulate, and/or recondition the compositions of the present disclosure. The methods and compositions of the present disclosure may also directly or indirectly affect any transport or delivery equipment used to convey the fluid to a well site or downhole such as, e.g., any transport vessels, conduits, pipelines, trucks, tubulars, and/or pipes used to compositionally move fluids from one location to another, any pumps, compressors, or motors (e.g., topside or downhole) used to drive the fluids into motion, any valves or related joints used to regulate the pressure or flow rate of the fluids, and any sensors (i.e., pressure and temperature), gauges, and/or combinations thereof, and the like. 
     For example, and with reference to  FIG.  1   , the disclosed methods may directly or indirectly affect one or more components or pieces of equipment associated with a system  10 , according to one or more embodiments. In certain embodiments, the system  10  includes a fluid producing apparatus  20 , a fluid source  30 , a dried shale inhibitor additive source  40 , and a pump and blender system  50  and resides at the surface at a well site where a well  60  is located. The fluid can be a fluid for ready use in a treatment of the well  60 . In other embodiments, the fluid producing apparatus  20  may be omitted and the fluid sourced directly from the fluid source  30 . 
     The dried shale inhibitor additive source  40  may include at least one dried shale inhibitor additive for combination with a fluid. The system  10  may also include additive source  70  that provides one or more additives to alter the properties of the fluid. For example, the other additives  70  can be included to reduce pumping friction, to reduce or eliminate the fluid&#39;s reaction to the geological formation in which the well is formed, to operate as surfactants, and/or to serve other functions. 
     The pump and blender system  50  may receive the fluid and combine it with other components, including the dried shale inhibitor additive source  40  and/or additional components from the additives source  70 . In certain embodiments, the resulting mixture may be pumped down the well  60  at a pressure suitable to introduce the fluid into one or more permeable zones in the subterranean formation. In certain instances, the fluid producing apparatus  20 , fluid source  30 , and/or dried shale inhibitor additive source  40  may be equipped with one or more metering devices or sensors (not shown) to control and/or measure the flow of fluids, dried shale inhibitor additives, proppants, diverters, bridging agents, and/or other compositions to the pumping and blender system  50 . In certain embodiments, the metering devices may permit the pumping and blender system  50  to source from one, some, or all of the different sources at a given time, and may facilitate the preparation of fluids in accordance with the present disclosure using continuous mixing or “on-the-fly” methods. Thus, for example, the pumping and blender system  50  can provide just fluid into the well at certain times, just additives at other times, and combinations of those components at yet other times. 
     While not specifically illustrated herein, the disclosed methods and systems may also directly or indirectly affect any transport or delivery equipment used to convey wellbore compositions to the system  10  such as, e.g., any transport vessels, conduits, pipelines, trucks, tubulars, and/or pipes used to fluidically move compositions from one location to another, any pumps, compressors, or motors used to drive the compositions into motion, any valves or related joints used to regulate the pressure or flow rate of the compositions, and any sensors (e.g., pressure and temperature), gauges, and/or combinations thereof, and the like. 
     For example, and with reference to  FIG.  2   , the dried shale inhibitor additives of the present disclosure may directly or indirectly affect one or more components or pieces of equipment associated with an exemplary wellbore drilling assembly  100 , according to one or more embodiments. It should be noted that while  FIG.  2    generally depicts a land-based drilling assembly, those skilled in the art will readily recognize that the principles described herein are equally applicable to subsea drilling operations that employ floating or sea-based platforms and rigs, without departing from the scope of the disclosure. 
     As illustrated, the drilling assembly  100  may include a drilling platform  102  that supports a derrick  104  having a traveling block  106  for raising and lowering a drill string  108 . The drill string  108  may include, but is not limited to, drill pipe and coiled tubing, as generally known to those skilled in the art. A kelly  110  supports the drill string  108  as it is lowered through a rotary table  112 . A drill bit  114  is attached to the distal end of the drill string  108  and is driven either by a downhole motor and/or via rotation of the drill string  108  from the well surface. As the bit  114  rotates, it creates a wellbore  116  that penetrates various subterranean formations  118 . 
     A pump  120  (e.g., a mud pump) circulates wellbore fluid  122  (e.g., a treatment fluid described herein) through a feed pipe  124  and to the kelly  110 , which conveys the wellbore fluid  122  downhole through the interior of the drill string  108  and through one or more orifices in the drill bit  114  (or optionally through a bypass or ports (not shown) along the drill string and above the drill bit  114 ). The wellbore fluid  122  is then circulated back to the surface via an annulus  126  defined between the drill string  108  and the walls of the wellbore  116 . At the surface, the recirculated or spent wellbore fluid  122  exits the annulus  126  and may be conveyed to one or more fluid processing unit(s)  128  via an interconnecting flow line  130 . After passing through the fluid processing unit(s)  128 , a “cleaned” wellbore fluid  122  is deposited into a nearby retention pit  132  (e.g., a mud pit). While illustrated as being arranged at the outlet of the wellbore  116  via the annulus  126 , those skilled in the art will readily appreciate that the fluid processing unit(s)  128  may be arranged at any other location in the drilling assembly  100  to facilitate its proper function, without departing from the scope of the scope of the disclosure. The dried shale inhibitor additive of the present disclosure may be added to the wellbore fluid  122  via a mixing hopper  134  communicably coupled to or otherwise in fluid communication with the retention pit  132 . The mixing hopper  134  may include, but is not limited to, mixers and related mixing equipment known to those skilled in the art. In other embodiments, however, the dried shale inhibitor additive of the present disclosure may be added to the wellbore fluid  122  at any other location in the drilling assembly  100 . In at least one embodiment, for example, there could be more than one retention pit  132 , such as multiple retention pits  132  in series. Moreover, the retention pit  132  may be representative of one or more fluid storage facilities and/or units where the dried shale inhibitor additives of the present disclosure may be stored, reconditioned, and/or regulated until added to the wellbore fluid  122 . 
     As mentioned above, the dried shale inhibitor additives of the present disclosure may directly or indirectly affect the components and equipment of the drilling assembly  100 . For example, the dried shale inhibitor additives of the present disclosure may directly or indirectly affect the fluid processing unit(s)  128  which may include, but is not limited to, one or more of a shaker (e.g., shale shaker), a centrifuge, a hydrocyclone, a separator (including magnetic and electrical separators), a desilter, a desander, a separator, a filter (e.g., diatomaceous earth filters), a heat exchanger, and any fluid reclamation equipment. The fluid processing unit(s)  128  may further include one or more sensors, gauges, pumps, compressors, and the like used store, monitor, regulate, and/or recondition solid additives and/or lost circulation materials. 
     The dried shale inhibitor additives of the present disclosure may directly or indirectly affect the pump  120 , which representatively includes any conduits, pipelines, trucks, tubulars, and/or pipes used to fluidically convey the treatment fluids downhole, any pumps, compressors, or motors (e.g., topside or downhole) used to drive the treatment fluids into motion, any valves or related joints used to regulate the pressure or flow rate of the dried shale inhibitor additive, and any sensors (i.e., pressure, temperature, flow rate, etc.), gauges, and/or combinations thereof, and the like. The dried shale inhibitor additive of the present disclosure may also directly or indirectly affect the mixing hopper  134  and the retention pit  132  and their assorted variations. 
     The dried shale inhibitor additives of the present disclosure may also directly or indirectly affect the various downhole equipment and tools that may come into contact with the dried shale inhibitor additive such as, but not limited to, the drill string  108 , any floats, drill collars, mud motors, downhole motors and/or pumps associated with the drill string  108 , and any MWD/LWD tools and related telemetry equipment, sensors or distributed sensors associated with the drill string  108 . The dried shale inhibitor additive of the present disclosure may also directly or indirectly affect any downhole heat exchangers, valves and corresponding actuation devices, tool seals, packers and other wellbore isolation devices or components, and the like associated with the wellbore  116 . The dried shale inhibitor additives of the present disclosure may also directly or indirectly affect the drill bit  114 , which may include, but is not limited to roller cone bits, PDC bits, natural diamond bits, any hole openers, reamers, coring bits, etc.

     To facilitate a better understanding of the present disclosure, the following examples of certain aspects of certain embodiments are given. The following examples are not the only examples that could be given according to the present disclosure and are not intended to limit the scope of the disclosure or claims. 
     EXAMPLES 
     The following examples demonstrate the preparation of dried shale inhibitor additives and laboratory tests conducted to evaluate the potency and stability of the dried shale inhibitor additives according to some embodiments of the present disclosure. 
     Example 1 
     In this example, a dried shale inhibitor additive was prepared. About 10 mL of liquid amine shale inhibitor (BaraSure™ W-674 Shale Stabilizer, available from Halliburton Energy Services, Inc.) and 50 mL of solvent in which the liquid shale inhibitor was substantially or entirely insoluble (isopropyl alcohol) were mixed together in a reaction vessel until a precipitation reaction occurred. The resulting precipitate was filtered through a filter paper and subsequently dried under vacuum. The purified precipitate product was a yellow dry powder. 
     Example 2 
     In this example, the potency of the dried shale inhibitor additive prepared in Example 1 was tested. The dried shale inhibitor additive was added to water in an amount of about 0.5 pounds per barrel (ppb). The resulting solution was tested with colorimetric assay to determine the relative concentration of the dried shale inhibitor additive compared to the liquid BaraSure™ W-674 Shale Stabilizer. The colorimetric assay was used to determine a calibration curve for the concentration of BaraSure™ W-674 Shale Stabilizer in a concentration range from about 1 pounds per barrel (ppb) to about 7 pounds per barrel (ppb) by absorbance measurements at 600 nm. According to the calibration curve, a solution at 0.5 pounds per barrel (ppb) of dried shale inhibitor additive was observed to have the same active concentration as a solution at 1.6 pounds per barrel (ppb) of liquid BaraSure™ W-674 Shale Stabilizer. These results demonstrate that the dried shale inhibitor additive has at least a 300% increase in potency as compared to an equivalent amount of the liquid shale inhibitor, as measured by weight. 
     Example 3 
     In this example, the stability of the dried shale inhibitor additive prepared in Example 1 was tested in terms of its hygroscopic properties. A small dry sample (about 100 mg) of the dried shale inhibitor additive in a container was exposed to the atmosphere at room temperature and pressure. After 3 days of exposure, the dried shale inhibitor additive remained a dry powder. After approximately 3 months, the dried shale inhibitor additive appeared to have taken up only a small amount moisture. These results demonstrate that the dried shale inhibitor additive is stable at room temperature and pressure, at least for shorter periods of time (e.g., under 3 months).
