    • The present invention is an error detection system for liquid crystal display (LCD) devices. The system comprises a photo-scanning device coupled to a computer and a LCD display driver. Faulty LCD cells are detected by using the photo-scanner to produce two images. The first image is produced by displaying a predetermined pattern on the LCD device. This pattern is inverted to produce the second image. By analyzing these two images, faulty LCD cells are located. The results of the analysis give the location of the faulty LCD cells.

    • A method of forming a subterranean well and a method of reducing the swelling of shale clay during the drilling of the subterranean well. The method features the use of a water based drilling fluid, wherein the drilling fluid is formulated to include: an aqueous based continuous phase; a weight material; an optional shale hydration inhibition agent and a shale encapsulator. The shale encapsulator has the formula: in which x and y have a value so that the molecular weight of the cation is in the range of about 10,000 to about 200,000 AMU; A is selected from C1-C6 alkyl, C2-C6 ether or C2-C6 amide; R, R′and R″are independently selectable C1-C3 alkyl; and B−is a charge balancing anion to the quaternary amine. The shale hydration inhibition agent and the shale encapsulator may be present in sufficient concentrations to reduce the swelling of the subterranean formation in the presence of water. Conventional additives may be included into the formulation of the drilling fluid, including: fluid loss control agents, alkaline reserve and other pH control agents, bridging agents, lubricants, anti-bit balling agents, corrosion inhibition agents, surfactants, solids suspending agents, and mixtures and combinations of these and other similar additives.

    • A method of electrically logging subterranean wells using a conductive double emulsion fluid includes a miscible combination of an oleaginous fluid, an emulsifier capable of forming a microemulsion, an emulsifier capable of forming an invert emulsion, and an electrolytic salt. A microemulsion is the continuous phase of an invert emulsion. The electrolytic salt or brine of the salt is present in a concentration sufficient to permit the electrical logging of the subterranean well. The fluid may additionally contain a polar organic solvent and a carbon dioxide buffer. The polar organic solvent may be an oil soluble glycol or glycol ether such as ethylene glycol, diethylene glycol, propylene glycol, polypropylene glycol, and the like. The electrolytic salt preferably is a quaternary amine salt having the formula: wherein R is an alkyl having 8 to 18 carbon atoms, R′ is 2 to 6 carbon atoms alkyl group, B is hydrogen, oxyalkyl having 1 to 4 carbon atoms or alkyl having 1 to 4 carbon atoms, A is hydrogen or alkyl with 1 to 4 carbon atoms, x+y=1 to 15, z is 0 to 3, and M− is a counter anion; or combinations thereof.
