Placing Fluid Into The Formation Patents (Class 166/305.1)
  • Patent number: 10443366
    Abstract: A method for the controlled delivery of a fracturing fluid to a well bore comprises formulating an aqueous base fluid such that it meets or exhibits desired physical and chemical characteristics for an optimal fracturing fluid. The formulation of the aqueous base fluid max involve commingling one or more sources of waste water with a source of fresh water followed by controlled injection of one or more additives. This process is substantially completed prior to delivering the aqueous base fluid to the well site. This allows the delivery of an optimal volume of the aqueous base fluid with homogeneously blended additives to the well bore.

    Abstract: A system and process for defining, blending and monitoring fresh water with subterranean produced formation fluids, with particular constituents of the blended waters being controlled for proper use in gel-type hydraulic fracturing operations. On-site measurements and calculations of clay stabilization replacement, through a Potassium Chloride (KCl) Equivalency calculation, provide feedback on water constituent adjustments that may be needed just prior to the gel-based hydraulic fracturing process. This assures adequate gel cross-linking times, delayed gel cross-linking times, and clay stabilization in the formation to be fractured.

  • Patent number: 10407610
    Abstract: Certain metal surfaces are often unable to be contacted effectively with fluids containing hydrofluoric acid due to significant corrosion issues. Steel surfaces represent but one example. Corrosion inhibitor compositions comprising an N-(phosphonoalkyl)iminodiacetic acid or any salt thereof can be used to suppress corrosion of steel surfaces, including those that contain multiple types or grades of steel. Methods for suppressing corrosion of a steel surface can comprise: contacting a steel surface with a corrosive environment, the corrosive environment comprising hydrofluoric acid; exposing the steel surface to a corrosion inhibitor composition, the corrosion inhibitor composition comprising an N-(phosphonoalkyl)iminodiacetic acid or any salt thereof; and suppressing corrosion of the steel surface being contacted with the corrosive environment through exposure to the corrosion inhibitor composition.

  • Patent number: 9656221
    Abstract: A liquid treatment method includes mixing a liquid with an agent to form a mixture, aging the mixture to obtain to a predetermined condition in at least one of the liquid and the agent, and dispensing the aged mixture. An interaction between the liquid and the agent causes the predetermined condition to occur. Also, a majority of the aging occurs while the mixture is in a dynamic state. A related system includes a mixer receiving a liquid and a drag reducing agent and an aging module connected to the mixer. The mixer disperses the drag reducing agent in the liquid to form a mixture and the aging module has a flow path along which the mixture flows. The flow path has a distance sufficient for a majority of the aging to occur while the mixture is in a dynamic state, wherein the aging changes the drag reducing agent to a predetermined condition.
