This invention is directed toward the loading of liquids, solids dissolved in liquids (known as solutions), suspensions, and solids heated to reduce viscosity, onto scoria, perlite, pumice, aerogels, activated alumina, fullerenes, graphite, molybdenum, magnetite, vermiculite, and activated charcoal to achieve a dry liquid concentrate (“DLC”) or slurry, for use in processes where a substance or substrate is to be expanded by a pressurized propellant and held in an expanded state by a proppant of granular solid material.
Use of the proper DLC or slurry is crucial in processes where a substance or substrate is to be expanded by a pressurized propellant and held in an expanded state by a proppant of granular solid material, including, without limitation, hydraulic fracturing for hydrocarbons, manufacturing, oil well treatment and production chemicals, biological treatment and remediation systems, bio-reactor substrates, animal attractants or repellants, flavors (such as in coffee and tea packets), fragrances, cleaning chemicals, pesticides, herbicides, fungicides, vitamins, fertilizers, combinations of the above, and any material, manufacturing process, or remediation process benefiting from a DLC or slurry.
A proppant is a solid material designed to keep an induced hydraulic fracture open, during or following a fracturing treatment. It is added to a fracking fluid, which may vary in composition depending on the type of fracturing used, and may be gel, foam, gas, or slickwater-based. Fluids make tradeoffs in material properties, including: viscosity, where more viscous fluids can carry more concentrated proppant; the energy or pressure demands to maintain a certain flux pump rate (flow velocity) that will conduct the proppant appropriately; pH; various rheological factors; and other considerations, such as toxicity and degradability.
There is a need for an expanded list of viable chemical carriers that improve the economic considerations and competition in the industry, improve carrier stability and chemical retention duration, and provide for fracturing fluids and a method of making up the most effective and safest fracturing fluid for each of the many varied conditions and varied processes which use some form of hydraulic fracturing.
For example, U.S. Pat. No. 5,964,291, issued on Oct. 12, 1999 to assignee AEA Technology PLC for “Well Treatment,” discloses chemical treatment agents supplied to a well or borehole extending through an earth formation, by subjecting the well to a fracturing treatment with a high pressure fluid and proppant particles. In the system, invented by Hugh Malcolm Bourne and Peter Arne Read, the proppant particles are thereby trapped in fractures in the earth formation. Some or all of the proppant particles are of porous insoluble inorganic material, and are impregnated with a chemical treatment agent, such as a scale inhibitor or a corrosion inhibitor. The porous particles may be of a ceramic or oxide material, such as a silica and/or an alumina-based material.
U.S. Pat. No. 6,209,646 was issued on Apr. 3, 2001 to assignee Halliburton Energy Services, Inc., covering “Controlling the Release of Chemical Additives in Well Treating Fluids.” In the '646 Patent, invented by Baireddy R. Reddy et al., methods of controlling the rates of release of chemical additives into treating fluids are provided. The methods are essentially comprised of causing a chemical additive in liquid form to be absorbed into a porous solid material whereby the chemical additive is encapsulated thereby, and when the resulting encapsulated chemical additive is combined with the treating fluid, the chemical additive is slowly released into the treating fluid. After being encapsulated, the liquid chemical additive is combined with the treating fluid and the treating fluid containing the encapsulated chemical additive is introduced into a well.
U.S. Pat. No. 7,493,955 was issued to assignee BJ Services Company on Feb. 24, 2009 for “Well Treating Compositions for Slow Release of Treatment Agents and Methods of Using the Same.” The '955 Patent, invented by D. V. Satyanarayana Gupta et al., discloses a composite of a well treatment agent adsorbed onto a water-insoluble adsorbent, useful in the treatment of oil and gas wells, which may be introduced, as a well treatment fluid, with a carrier fluid. The water-insoluble adsorbent may be activated carbon, silica particulate, precipitated silica, zeolite, diatomaceous earth, ground walnut shells, fuller's earth, and organic synthetic high molecular weight water-insoluble adsorbents. Suitable as the well treatment agent are scale inhibitors, corrosion inhibitors, paraffin inhibitors, salt inhibitors, gas hydrate inhibitors, asphaltene inhibitors, oxygen scavengers, biocides, foaming agent, emulsion breakers, and surfactants.
Lastly, U.S. Publ. No. 2014/0206080, which was published on Jul. 24, 2014 by inventors Ramiro Trevino et al., discloses “Composition and Method for Delivery of Living Cells in a Dry Mode Having a Surface Layer.” The system generally relates to compositions and methods of delivering living cells in a dry mode, wherein the compositions include a surface layer disposed on the outer surface of the composition that is permeable to carbon dioxide and oxygen. The compositions may be used to deliver living cells to a delivery point without the use of expensive refrigerants such as dry ice or liquid nitrogen.
There remains a need for fracturing fluids and a method of creating more effective and safe fracturing fluids that may be applied to each of the many varied conditions and processes that use hydraulic fracturing, as well as carrier alternatives to those presented above that provides higher levels of competition and improved economic conditions, carrier stability, and chemical retention duration, as discussed in more detail below.
This invention provides an expanded list of viable chemical carriers that improve the economic considerations and competition in the industry, improve carrier stability and chemical retention duration, and further provides for fracturing fluids and a method of making up the most effective and safest fracturing fluid for each of the many varied conditions and varied processes which use some form of hydraulic fracturing, by loading liquids, solids dissolved in liquids (solutions), suspensions, or solids heated to reduce viscosity, onto scoria, perlite, pumice, aerogels, activated alumina, fullerenes, graphite, molybdenum, magnetite, vermiculite, and activated charcoal to achieve a dry liquid concentrate (DLC) or slurry, for use in processes where a substance or substrate is to be expanded by a pressurized propellant and held in an expanded state by a proppant of granular solid material, including, without limitation, hydraulic fracturing for hydrocarbons, manufacturing, oil well treatment and production chemicals, biological treatment and remediation systems, bio-reactor substrates, animal attractants or repellants, flavors (such as in coffee and tea packets), fragrances, cleaning chemicals, pesticides, herbicides, fungicides, vitamins, fertilizers, combinations of the above, and any material, manufacturing process, or remediation process benefiting from a DLC or slurry.
Reference will now be made to the drawings, wherein like parts are designated by like numerals, and wherein:
Referring to
In one embodiment of the present invention, down hole chemicals are loaded onto carriers such as scoria, perlite, pumice, aerogels, activated alumina, fullerenes, graphite, molybdenum, magnetite, vermiculite, and activated charcoal (5.1 wt. % to 9.9 wt. % and in excess of 90 wt. %), and are introduced to the formation via being mixed with propellants or other means. In downstream gas and oil well production, chemicals are loaded onto such carriers such as scoria, perlite, pumice, and so forth, and introduced into the stream by means of a bed placed inline. The carrier substrates can impart time release properties, avoid undesirable side reactions prior to use, improve shelf life, and increase distribution of the treatment system. The activated carbon can be calcined to increase propellant strength. The particle size of the activated carbon can be sized to incorporate well with the other propellants or proppants. Perlite and pumice in particular have a low density, and allow for DLCs that can float on water. Scoria, in contrast, possesses a high density, which makes it preferable for use in applications heavier than water. Meanwhile, scoria and pumice each possess hard structures that can allow for higher-crush applications. Precipitated silica and activated carbon can be over-saturated (in excess of 90 wt. %) with liquids to form slurries.
In another embodiment of the present invention, cleaning chemicals, such as surfactants, can be loaded onto carriers like scoria, perlite, pumice, aerogels, activated alumina, fullerenes, graphite, molybdenum, magnetite, vermiculite, and activated charcoal for delivery on hydrocarbon contaminated substrates.
In another embodiment of the present invention, cleaning chemicals, such as surfactants, can be loaded onto carriers such as scoria, perlite, pumice, aerogels, activated alumina, fullerenes, graphite, molybdenum, magnetite, vermiculite, and activated charcoal for delivery on hydrocarbon contaminated substrates.
In another embodiment of the present invention, microbial and enzymatic systems are loaded onto carriers like scoria, perlite, pumice, aerogels, activated alumina, fullerenes, graphite, molybdenum, magnetite, vermiculite, and activated charcoal. The surface area of the carriers enhances microbial growth. The densities of scoria and pumice can allow the system to sink to the bottom of the water. The carrier's particle size can be selected to lock into the soil substrate or facilitate application via rotary spreader. Proper carrier substrate formulation can allow oil and stain remediation of concrete or gravel, such as found at fueling stations, fuel transfer and oil change facilities, railway beds and yards, convenience stores, and so forth. Such systems can be used in the treatment of hydrocarbons, heavy metals, radioactivity, salt, or other contaminants.
In another embodiment of the present invention, microbial and enzymatic systems are loaded onto carriers like scoria, perlite, pumice, aerogels, activated alumina, fullerenes, graphite, molybdenum, magnetite, vermiculite, and activated charcoal, and act as a microbial delivery system in a bio-reactor tank. The surface area of the carrier enhances growth of the microbes and in bed form improves contact with the treated material, such as contaminated water.
In another embodiment of the present invention, liquid animal attractants (such as Pheromones and/or flavors or fragrances) or repellants are loaded onto carriers such as scoria, perlite, pumice, aerogels, activated alumina, fullerenes, graphite, molybdenum, magnetite, vermiculite, and activated charcoal, which possesses a large internal carrying capacity. The internally absorbent carriers can act to extend the shelf life of normally temperature, oxygen and light sensitive agents, as well as allow time-release action and decrease movement in the soil.
In another embodiment of the present invention, flavors and fragrances loaded onto activated carbon can be blended with beverage components that are filtered via membrane, such as tea bags, coffee filters and cartridges like those found in a Keurig system or multi-component system, to avoid premature reaction between the flavors/fragrances with the tea leaves, coffee granules, or other beverage components.
In another embodiment of the present invention, fragrances that are incompatible with solid substrates, such as potpourri, can be loaded onto such scoria, perlite, pumice, aerogels, activated alumina, fullerenes, graphite, molybdenum, magnetite, vermiculite, and activated charcoal, to improve compatibility with the solid, increase shelf life, and act as a time release system.
In another embodiment of the present invention, fertilizers, pesticides, herbicides and fungicides can benefit from carriers such as scoria, perlite, pumice, aerogels, activated alumina, fullerenes, graphite, molybdenum, magnetite, vermiculite, and activated charcoal as the UV resistance, soil retention, bulking/dilution and mechanical delivery of the active ingredients can be improved.
In another embodiment of the present invention, vitamins can be delivered more efficiently in aquaculture applications, as the carriers like scoria, perlite, pumice, aerogels, activated alumina, fullerenes, graphite, molybdenum, magnetite, vermiculite, and activated charcoal-based DLC's can improve UV, temperature and oxygen resistance of the vitamins, allow for time-release of the nutrients into the water, decrease the loss due to dilution in open water systems, and help clean the water.
