A garment hanger for holding a garment has body having a top portion with a first shoulder portion and a second shoulder portion. A hooking member includes an arm that extends away from the body to a hook that can be hooked on an object, such as a bar. A connection mechanism that connects the hooking member to the body includes a hinge mechanism that allows the hooking member to be rotated towards and away from the body so that the garment hanger can be moved from an unfolded configuration to a folded configuration. The garment hanger can also include one or more protrusions on the body that can engage a notch to secure the hooking member in the folded configuration and/or to allow for cascading of a plurality of garment hangers. In one version, the garment hanger is designed to hold swimwear.

A method for determining characteristics of a mesoporous material using a desiccation or hydration test is disclosed. The test may involve using a test fluid and exposing sample of a core to a controlled environment, then weighing the samples. The samples may be core samples, comminuted samples, or cuttings. Utilizing the determined characteristics, properties of the mesoporous material, such as porosities, absolute permeabilities and relative permeabilities may be determined.

Characterization methods

In situ channelization treatment fluids are used in a multistage well treatment. Also, methods, fluids, equipment and/or systems relating to in situ channelization treatment fluids are used for treating a subterranean formation penetrated by a wellbore.

Well treatment

Well treatment with an untethered and/or autonomous device. Also, in situ channelization treatment fluids are used in multistage well treatment with an untethered and/or autonomous device; and methods and/or systems for treating a subterranean formation penetrated by a wellbore, relating to in situ channelization treatment fluids, which may optionally be energized, and untethered and/or autonomous devices.

Well treatment with untethered and/or autonomous device

This invention relates to compositions and methods of removing an organic deposit including introducing a fluid, wherein the fluid comprises at least two non-polar organic solvents and at least two polar organic solvents; allowing the fluid to dissolve at least a portion of the organic deposit; and removing at least a portion of the fluid. This invention relates to compositions and methods of removing an organic deposit including introducing a fluid, wherein the fluid comprises at least two non-polar organic solvents and at least two polar organic solvents, wherein the non-polar organic solvents comprise aromatic naphtha, terpenes, kerosene, and combination thereof, and wherein the polar solvents comprise heavy aromatic naphtha, cyclohexanone, N-2-methyl pyrrolidone, N-ethyl-2-pyrrolidone, and combination thereof, allowing the fluid to dissolve at least a portion of the organic deposit, and removing at least a portion of the fluid.

Asphaltene removal composition and methods

An automated cat litter box includes a cat litter tray, a cat litter return bin that collects soiled cat litter from the cat litter tray and that returns recycled cat litter to the cat litter tray, a control unit, and one or more drive units operated by the control unit to drive the cat litter tray and the cat litter return tray to automatically recycle the soiled cat litter during a cat litter box cleaning cycle.

Cat litter box system

The invention provides economically effective methods for hydraulic fracturing a subterranean formation that ensure improvement of the hydraulic fracture conductivity because of forming strong proppant clusters uniformly placed in the fracture throughout its length. One of these methods comprises: a first stage comprising injection of fracturing fluid into a borehole, the fluid containing thickeners to create a fracture in the formation; and a second stage comprising introduction of proppant into the injected fracturing fluid to prevent closure of the created fracture, and further, comprising introducing an agent into the fracturing fluid to provide formation of proppant clusters in the created fracture and channels for flowing formation fluids.

Method for hydraulic fracturing of subterranean formation

Methods are presented to induce a screenout during a subterranean formation fracturing or combined fracturing and gravel packing treatment by laying down a filter cake early in the treatment, then injecting proppant slurry, and then while proppant slurry injection continues chemically damaging the filter cake with one or more filter cake degradation agents so that leak-off increases, the concentration of proppant in the fracture increases, and the proppant screens out. The additional use of filter cake degradation agent aids and bridging-promoting materials is included.

Methods for controlling screenouts

A method for treating a wellbore (or well casing) and the contiguous wellbore area to remove scale (mineral deposits comprised of, e.g., BaSO4, CaCO3, etc.) in the context of hydrocarbon recovery and other applications is disclosed, said method including contacting the scale with a fluid comprised of an ionic liquid or liquids.

Scale removal

Methods are provided for stimulation of hydrocarbon production from low permeability formations by hydraulic fracturing, acid fracturing, and hydraulic fracturing followed by gravel packing in a single operation. The methods use a first injected viscous pad made with low concentration uncrosslinked polymer to initiate and propagate the fracture and control fluid loss, followed by a second injected fluid gelled with a viscoelastic surfactant for carrying proppant or acid into the fracture.

Methods for stimulating hydrocarbon production

A method for hydraulic fracturing subterranean formation whereby at least part of the fracture is propped with proppant material essentially in the form of elongated particles having a shape with a length-basis aspect ratio greater than 5, preferably such as metallic wire segment. The remaining part of the fracture may be propped with conventional non-metallic proppant. Fracture conductivity is optimized.

This Invention relates to a novel reversible thickener, i.e., a fluid whose viscosity can be carefully modulated&mdash;from very low viscosity to sufficient viscosity to act as a barrier to further flow; particularly preferred embodiments are directed to fluids and methods for stimulating hydrocarbon low viscosity to sufficient viscosity to act as a barrier to further flow; particularly preferred&mdash;bearing formations&mdash;i.e., to increase the production of oil/gas from the formation. In particular, the Present Invention is directed to a family of fluids (and methods incorporating those fluids) intended to be pumped through a wellbore and into the hydrocarbon-bearing formation.

Fluid system having controllable reversible viscosity

Methods are provided for increasing the production of hydrocarbons from shaly formations that contain adsorbed condensed hydrocarbon gases by treating such formations with dewatering compositions comprising surfactants that cause the surfaces of the formation to be or to remain oil-wet. The methods may be used in stimulation (acidizing or acid fracturing or hydraulic fracturing), remediation or workover, and in enhancing flow from natural fractures or from unstimulated formations.

Methods for dewatering shaly subterranean formations

Herein is disclosed a well completion or stimulation fluid, comprising (i) a carrier fluid; (ii) a viscoelastic surfactant; and (iii) a fluid loss control additive (FLA) comprising at least one polymer and at least one crosslinker. The fluid may further comprise proppant or gravel, if it is intended for use as a fracturing fluid or a gravel packing fluid, although such uses do not require that the fluid comprise proppant or gravel. Also disclosed herein are methods of fracturing a subterranean formation, comprising (i) providing a fracturing fluid discussed above and (ii) injecting the fracturing fluid into the formation at a pressure sufficiently high to fracture the formation. In addition, disclosed herein are methods of gravel packing a wellbore, comprising (i) providing a gravel packing fluid discussed above and (ii) injecting the gravel packing fluid into the wellbore.
