  • Patent number: 9016377
    Abstract: A chopper mechanism for providing a fiber to a fluid at an oilfield. The chopper mechanism may be employed to process the fiber from an uncut form to a cut form in order to provide a mixture of the fluid and the fiber with flowback inhibiting character. Techniques of employing the chopper mechanism may be utilized at the site of an oilfield for applications such as fracturing, cementing, and drilling. Additionally, the chopper mechanism itself may be made available as a large high capacity chopper assembly, or a smaller handheld chopper gun for slower rate fiber supply operations.
    Type: Grant

  • Patent number: 8002049
    Abstract: A method of preventing or treating lost circulation during the drilling of a well comprises the addition, at concentration ranging between about 0.5 and 6 pounds per barrel, of water-dispersible fibers having a length between about 10 and 25 mm, for instance glass or polymer fibers, to a pumped aqueous base-fluid including solid particles having an equivalent diameter of less than 300 ?m. The base-fluid with the solid particles can be the drilling fluid or a small-volume pill specially pumped for curing lost circulation.
