Providing essential oils and/or saponins such as, garlic oil, cinnamon bark oil or powder, and lemongrass oil to an environmental medium to disrupt the enzyme and coenzyme systems, that are integral parts of the methanogenesis process. The disruption limits the growth and reproduction of the methanogens that normally compete with slower-growing, halo-respiring bacteria for the hydrogen donors within the environmental medium (either naturally occurring or provided via fermentable substrates provided to the environmental medium of part of a reduction process). The amount of methane produced during in situ remediation processes is also reduced. The essential oils/saponins are harmless to the slower-growing, halo-respiring bacteria that are utilized to dechlorinate containments in the environmental medium. The essential oils/saponins can be provided alone or along with various organic hydrogen donors, zero-valent iron (ZVI) or other surfactants in order to enhance the biodegradation (reductive dechlorination) of the targeted contaminants. 1.

The primary function of the collapsible enclosure is to capture, isolate, and allow for the permanent removal of otherwise easily dispersed contaminates in aquatic sediments and detritus of water bodies. Once deployed, the collapsible enclosure creates an isolated volume of water above these media. Contaminated sediments and detritus covered by the enclosure can then be efficiently removed either by their dissociation from sediment and detritus and into a soluble form within the enclosed water volume or by suspension of contaminated sediments and detritus within the enclosure. The dissolved or suspended contaminants within the enclosure could then be removed by an external pump, for treatment or disposal of recovered water and solids. 1. A collapsible and mobile enclosure apparatus for removal of contaminated aquatic sediments and detritus , and for removal and control of targeted nuisance , noxious or invasive aquatic fauna and flora comprising:A.

According to the triangle method, the hole spacing is perpendicular to the groundwater flow direction, the row spacing is along the groundwater flow direction, and the flow diffusion in the groundwater during the effective time of the remediation agent reaction is considered. Under high pressure rotary injection, the remediation agent and a certain proportion of bromide ions are simultaneously injected into the aquifer as a tracer. The diffusion of the agent is determined by observing the phenomenon of slurry-returning and slurry-channeling of adjacent injection points. After the completion of the injection, the groundwater is quickly sampled in fixed depth, the tracer concentration is quickly detected on site, and the concentration of bromide ions in the groundwater is compared with the background value. Comprehensive determination determines the optimal diffusion radius. 1.

Injection Tip And Method For Nucleating And Propagating Hydraulic Fractures From Probe Rods

Номер: US20170239698A1
Автор: Durant Neal, Ross Chapman, Slack William, Terkelsen Mads
Принадлежит: FRX, Inc.

An injection tip assembly 10 and methods for use more reliably provide for delivery of fluid substances, such as materials that promote removal, destruction, or isolation of contaminants, into targeted zones within soil or bedrock. The injection tip assembly permits the application of pressurized fluid so as to erode or cut a desired cavity or eroded volume within the subsurface , allows for timely observation, adjustment, and control of pressure within the cavity, and directs the delivery of a second substance or fluid that may incorporate desired materials. The consequence of managed erosion and pressure control is to nucleate and propagate a hydraulic fracture of desirable form that optimally delivers remedial agents throughout the targeted formation. 1. A method for nucleating and propagating hydraulic fractures , the method comprising:driving an injection tip into a subsurface, the injection tip having a first channel and a second channel;dispensing a first substance through the first channel of the injection tip and outwardly therefrom to form a cavity in the subsurface;allowing the first substance, and any subsurface material carried thereby as a result of the dispensing of the first substance, to enter the second channel at the injection tip so as to be routed upwardly from the subsurface;thereafter dispensing a second substance through the second channel of the injection tip and outwardly therefrom into the cavity; andcontrolling the pressure in the cavity during the dispensing of the first substance and the dispensing of the second substance, thereby to construct a nucleation cavity of suitable geometry while limiting pressure and thereafter controlling the pressure to cause a hydraulic fracture of desired orientation and form.2. The method of claim 1 , wherein the controlling further comprises:sensing the pressure in the cavity; andvarying the rate of the allowing and/or the dispensing of the first substance and/or the dispensing of the second substance, ...
