    摘要: A cement sample testing apparatus including a first pressure zone; a second pressure zone; and a pressure control system. The pressure control system can be in fluid communication with the first pressure zone and the second pressure zone, operable to raise the first pressure zone to a first pressure above ambient pressure, and operable to raise the second pressure zone to a second pressure above ambient pressure. A method for determining mechanical properties for a sample cement composition can include applying a first pressure condition to a first portion of the sample cement composition; applying a second pressure condition raised to a second portion of the sample cement composition; and determining one or more mechanical properties of the sample cement composition based at least in part on the pressure conditions present at the failure of the sample cement composition.

    摘要: A system and method to model and analyze the mixing energies of high-yielding non-Newtonian fluids to prevent chemical lost circulation is disclosed. Laboratory tests are preformed under varying conditions from which data on the mixing energies needed to optimize the use of high-yielding non-Newtonian fluids to prevent lost circulation is obtained. This data is then applied to a non-linear mathematical modeling system that is capable of scaling the data to give a dimensionless value. This value can be combined with historic information to predict optimal flow rates and mixtures to prevent chemical lost circulation. This data may be verified by means of simulation, lab testing, or application to a full-size well.

    摘要: An air-driven ceiling fan uses air from the duct work system of a home such as the central air-conditioning system to harness that air flow and drive a ceiling fan having a plurality of blades which are spaced from the ceiling and upon a common shaft in a horizontal plane. Air flow through the duct work drives a squirrel cage blower which is mounted about a vertical axis so that air flow through the duct work also drives the squirrel cage blower and the ceiling fan.

    摘要: An excess water control device for a potted plant provides a pot having a side wall, bottom wall, interior, open top, and one or more openings in the bottom wall. A soil mass is contained within the pot interior, occupying the pot interior with a growing plant. One or more wicking feet support the pot, each foot extending from a position below the pot to the pot interior and the contained soil medium. Each foot can be of a larger diameter lower section upon which the pot rests and a smaller diameter upper section that engages the soil mass inside the pot.
