20140048532 | WATER STORAGE TANK - A water storage tank is formed by a plurality of curved wall sections adapted to be secured together to form a circular tank. A ground mat is placed on the ground and extends outwardly of the tank wall. A plurality of hold down members are placed at the inside juncture of the tank wall and ground mat. A flooring sheet overlaps the ground mat and extends up and over the side wall of the tank and is clamped to an upper portion of the wall. A tubular fitting extends through a lower portion of the side wall to provide an inlet and outlet for water. | 02-20-2014 |
20140048533 | HYDRAULIC HOLD DOWN FOR A WATER STORAGE TANK - A hydraulic hold down has horizontal and vertical extending portions and a curved section connecting the two. The hold down is adapted to be placed at the juncture of a floor mat and circular side wall of a water storage tank to keep the floor mat in place and to reinforce the side wall. The hold down has a curvature that conforms to the curvature of the circular sidewall of the water storage tank. | 02-20-2014 |
20140048539 | CLAMP FOR A WATER STORAGE TANK - A clamp for securing a flexible sheet to the upper portion of a wall of a water tank includes a pair of thin, flexible strips spaced apart by a plurality of spacers near a top portion of the strips. At least one rod or threaded bolt extends through holes provided in the strips below the spacers. Nuts carried by the rod or bolt can be moved inwardly so as to deflect the flexible sheets inwardly thereby clamping the flexible sheet between the clamp and the tank wall. | 02-20-2014 |
20140202703 | Method of Reducing Corrosion on Metal Surfaces - A method for reducing corrosion on the exterior or interior surface, for example coiled tubing and casing, is disclosed. The method includes mixing a selected surfactant and particles of a polymer in oil, then adding the oil to water and contacting the surfaces of the tubing with the mixture. | 07-24-2014 |
20140202709 | Method of Completing a Well Using a Friction Reducing Completion Fluid - A method for reducing the friction forces between tubulars, for example coiled tubing in casing, is disclosed. The method includes mixing a selected suspending agent and surfactant and polymer particles in oil, then adding the mixture to water and pumping the mixture down the tubing. The mixture is particularly useful in coiled tubular drilling inside casing of an oil or gas well. The formulation has also been found to reduce corrosion on metal surfaces. | 07-24-2014 |
20140206582 | Completion Fluid for Reducing Friction Between Metal Surfaces - A liquid mixture reduces the friction between two surfaces, at least one of which is moving with respect to the other such as tubing moving within the casing of an oil or gas well. The mixture includes an oil, a suspending agent, polymer particles and a surfactant. | 07-24-2014 |
20150055432 | Polymer Blending System - A system for blending polymers and other chemicals in an aqueous liquid is provided. Static mixers and tubes, preferably in one or more tube bundles, provide a volume sufficient to allow a residence time in the system to hydrate a polymer. Static mixers may be integrated with a tube bundle. The system may be mounted on a portable base such as a trailer. The concentration of polymer and chemicals in water may be controlled by a controller. A variable speed electric pump or a metering valve may be utilized to precisely control the amount of polymers or other chemicals added to the aqueous liquid. | 02-26-2015 |
20150076141 | LIQUID STORAGE TANK FORMED OF A PLURALITY OF PANELS - A fluid storage tank is formed by a plurality of wall panels positioned on top of a floor mat. Each wall panel includes a curved sheet of a non-metal material, for example fiberglass, first and second side frame members and a plurality of reinforcing strips that extend between the side frame members. The reinforcing strips are secured to the side frame members. The panels include complimentary fastening members that allow the curved side panels to be connected end to end so as to form a circular fluid storage tank in conjunction with a floor mat. | 03-19-2015 |
