Abstract: A system and method for providing information about an object. In one embodiment, a system includes a hand held device and a wireless radio frequency (RF) tag. The hand held device is wirelessly coupled to a central computer system, and includes a wireless radio frequency (RF) tag reader, and a display panel. The wireless RF tag is attached to an object offered for sale, and includes an identifier for the object. The hand held device is configured to: wirelessly scan the wireless tag; to extract the identifier from information wirelessly received from the wireless tag via the wireless scan; to wirelessly communicate the identifier to the central computer system as part of a request for information concerning the object; and upon receiving a response to the request for information, to display the information concerning the object via the display panel.

Abstract: A method for preparing a thermally stable well servicing fluid in the form of an oil-in-water (O/W) macroemulsion, a water-in-oil (W/O) macroemulsion or a water-in-oil (W/O) microemulsion at the well drilling location is provided. The servicing fluid is prepared by mixing a hydrocarbon phase, a water phase and a surfactant phase to obtain either an O/W macroemulsion, a W/O macroemulsion or a W/O microemulsion. The surfactant phase comprises a first surfactant and/or a second surfactant. The first surfactant comprises a fatty acid mixture and a hygroscopic first additive. The second surfactant comprises a C4-C6 alcohol. Whether or not an O/W macroemulsion, W/O macroemulsion or a W/O microemulsion is produced is determined by the concentration of the phases, the first surfactant, the second surfactant and the timing upon which the first additive, water phase and second surfactant are introduced to the mixture.

Abstract: A thermally stable well servicing fluid includes a fluid portion in the form of an oil-in-water emulsion; and a surfactant mixture including an anionic surfactant selected from the group consisting of alkali metal salts of alkyl sulphates, alkali metal salts of alkyl sulphonates, and mixtures thereof, and a non-ionic surfactant selected from the group consisting of ethoxylated alkyl phenols, ethoxylated aliphatic alcohols and mixtures thereof, the surfactant mixture containing the anionic surfactant and the non-ionic surfactant at a ratio by weight of between about 70:30 to about 80:20, the fluid being stable at temperatures exceeding 220.degree.
