An electro-optic display comprising at least two separate layers of electro-optic material, with one of these layers being capable of displaying at least one optical state which cannot be displayed by the other layer. The display is driven by a single set of electrodes between which both layers are sandwiched, the two layers being controllable at least partially independently of one another. Another form of the invention uses three different types of particles within a single electrophoretic layer, with the three types of particles being arranged to shutter independently of one another.

Method for driving two layer variable transmission display

A well treatment additive includes a siloxane surfactant, a solvent and an aqueous phase. The solvent is preferably a terpene hydrocarbon. Also disclosed is a method for using the well treatment additive to form and enhance the properties of terpene solvent based additives useful for the treatment of oil and gas wells. Methods of using the novel well treatment additives include using the additives in a variety of well treatment processes including, but not limited to, acidizing operations, hydraulic fracturing operations, well remediation operations and water removal operations.

Siloxane surfactant additives for oil and gas applications

Methods and compositions comprising an emulsion or a microemulsion for use treating an oil and/or gas well are provided. In some embodiments, the emulsion or the microemulsion comprises an aqueous phase, a solvent, a surfactant comprising alkyl polyglycoside, an alcohol, and, optionally, one or more additives.

Methods and compositions incorporating alkyl polyglycoside surfactant for use in oil and/or gas wells

A display device () comprises a reflective display () arranged to render a first image viewable through a viewing surface and a projection means (-) arranged to render a second image viewable in reflection on the viewing surface, the reflective display () and the projection means (-) being mounted on a common frame.

Illumination systems for reflective displays

Methods and compositions comprising an emulsion or a microemulsion for use in various aspects of the life cycle of an oil and/or gas well are provided. In some embodiments, the emulsion or the microemulsion comprises water, a solvent, and a surfactant, and optionally, one or more additives.

Methods and compositions for use in oil and/or gas wells

Compositions relating to microemulsions or diluted microemulsions for treating gas wells having wellbores and methods related to treating gas wells having wellbores using the same are generally provided. In some embodiments, the microemulsions or diluted microemulsions have an especially low surface tension at a gas well bottom hole temperature and pressure.

Diluted microemulsions with low surface tensions

Emulsion or microemulsion for treating an oil or gas well having a wellbore are provided, and related methods. In some embodiments, the emulsion or microemulsion comprises an aqueous phase; a surfactant; and a non-aqueous phase comprising a first type of solvent and a second type of solvent. In some embodiments, the first type of solvent is a long chain hydrocarbon. In some embodiments, the second type of solvent is an oxygenated solvent. The emulsion or microemulsion may comprise additional components (e.g., at least one type of co-solvent).

Methods and compositions for stimulating the production of hydrocarbons from subterranean formations

Methods for treating an oil or gas well having a wellbore by, for example, injecting an emulsion or microemulsion into the wellbore to increase formation crude oil or formation gas production by the well. Methods of selecting compositions for treating an oil or gas well having a wellbore to increase formation crude oil or formation gas production by the well.

Methods and compositions comprising an emulsion or a microemulsion for use in various aspects of the life cycle of an oil and/or gas well are provided. In some embodiments, the emulsion or the microemulsion comprises water, a solvent, and a surfactant, and optionally, one or more additives. In some embodiments, methods for preventing, reducing, or eliminating a crude oil emulsion in an oil and/or gas well are provided.

Methods and compositions for use in oil and/or gas wells comprising microemulsions with terpene, silicone solvent, and surfactant

Methods comprising a microemulsion for use in various aspects of the life cycle of an oil and/or gas well are provided. In some embodiments, the microemulsion comprises water, a solvent, and a surfactant, and optionally, one or more additives.
