The present invention relates to a method of preparing a gas coolant for the direct cooling of a unit operation under a fixed heat load from its normal operating temperature (e.g., 300° F. and above) to a lower temperature (e.g., below 100° F.) in order to allow for maintenance or other non-routine work to be carried out in said unit operation.

Method for controlling a recycle gas stream utilizing an ejector for the cooling of a unit operation

The present invention relates to a method of rapidly decontaminating hydrocarbon contaminated equipment by sequencing a cleaning mist or foam, an encapsulating mist or foam and a dry carrier gas.

Method to remove explosive and toxic gases and clean metal surfaces in hydrocarbon equipment

A dual-mode LNG liquefier arrangement that is configurable to operate in a first mode broadly characterized as a low pressure, liquid nitrogen add LNG liquefier without turbo-expansion or a second mode broadly characterized as a low pressure, liquid nitrogen add LNG liquefier with turbo-expansion.

Dual mode Liquefied Natural Gas (LNG) liquefier

The present invention relates to a novel integrated system for providing nitrogen (N2) to a variety of industrial service applications such as, for example, process unit drying, pipeline purging, reactor cooling, vessel inerting, pipeline displacement.

Nitrogen service supply system

The present invention relates to a proppant laden fracture fluid having a Mitchell quality of at least 50% and fracturing a subterranean formation therewith.

Process for making and supplying a high quality fracturing fluid

The present disclosure is directed to a composition and method of fracturing a formation penetrated by a well-bore. The composition and method comprises providing a fracturing fluid that is carbon dioxide (CO) with at least one friction reducing polymer that is a fluoropolymer dissolved in the COat a concentration of about 0.001 to 0.4 weight percent.

Fracturing fluid composition and method utilizing same

The present invention relates to a process of supplying a proppant-containing fracturing fluid to a wellhead, wherein the proppant-containing fracturing fluid can be continuously supplied during the fracture treatment.

Process for continuously supplying a fracturing fluid

A composition and method required for providing a fracturing fluid pumped down a well bore and into a subterranean formation under conditions of pressure that will fracture the subterranean formation is described. More specifically, the composition increases the recovery of hydrocarbons from a geological formation penetrated by a well bore, wherein the composition includes a fracturing fluid that is liquid carbon dioxide (LCO) with proppant to aid transport of the proppant in suspension, and thereby create a fracture using a fracturing fluid which is the thickened composition containing fumed silica. When the composition is without a proppant, the viscosity of the composition is increased in order to improve the fracturing operation through aspects such as increased fracture width and reduced fluid leak-off.

Fracturing fluid composition and method of using same in geological formations

The present disclosure is directed to a composition and method of fracturing a formation penetrated by a well-bore. The composition and method comprises providing a fracturing fluid that is liquefied carbon dioxide (LCO) with at least one friction reducing polymer that is a polysiloxane dissolved in the LCOat a concentration of about 0.001 to 1.0 weight percent, and a first at least one co-solvent, and optionally a second at least one co-solvent that has a closed cup flash point greater than the first at least one co-solvent, in order to enable dissolution of the polymer in order to effect friction reduction.

A method, system, and apparatus required for creating a mixture of dry proppant and liquid carbon dioxide (LCO) for fracturing oil and gas formations is presented. The operation includes making a mixture of dry proppant and liquid carbon dioxide (LCO) for use in a fracturing operation by supplying dry proppant that is pressurized to between 75 and 600 psia with a gas; further supplying a stream of sub-cooled LCOhaving a pressure substantially equal to that of the pressurized dry proppant; and adding dry, pressurized proppant to the stream of sub-cooled LCO, thereby forming a mixed LCOand proppant fracturing slurry.

System and apparatus for creating a liquid carbon dioxide fracturing fluid

The present disclosure is directed to a method of making a fracturing fluid and system of fracturing a formation penetrated by a well-bore. The method includes providing a fracturing fluid that is liquefied carbon dioxide (LCO) and a co-solvent in a quantity of 1-19 wt %, and at least one friction-reducing polymer in a quantity of 0.001-1.0 wt % of the fracturing fluid composition, wherein the friction-reducing polymer is initially disposed in an emulsion, and is at least partially soluble in the co-solvent and LCOmixture.
