Abstract: A self-contained evaporation system for use in disposing of excess water from oil and gas drilling operations is provided. The system includes a water holding tank in which the wastewater is preheated, an evaporation chamber mounted over the holding tank and having an open top, a nozzle system located within the chamber for producing a fine liquid mist, and fans disposed within the chamber for producing an air flow that carries the mist out the open top of the chamber. The system can be set up and taken down by one person in an hour or less, can be used with pond or tank operations, and is capable of operating in high winds and sub-zero temperatures. The system can be carried and mounted on a trailer for easy transport to and from various drilling sites.

Abstract: A method of placing a fiber on a substrate includes holding at least one fiber under tension, aligning the held fiber with a groove formed into a substrate, moving the substrate towards the fiber to place the fiber in the groove, fixing the position of the fiber under tension in the groove, and releasing the fiber.
