  • Patent number: 8066058
    Abstract: A method for breaking a fracturing fluid includes identifying application parameter(s) including a subterranean formation temperature, and determining an acid precursor concentration in response to the application parameter(s). The method further includes providing a treatment fluid including a carrier fluid, a metallic peroxide breaker, and an amount of an acid precursor according to the acid precursor concentration, and treating the subterranean formation with the treatment fluid. The application parameter(s) may further include a flowback wait time, a composition of the metallic peroxide breaker, a gel loading of the carrier fluid, and/or a permeability of the subterranean formation. The metallic peroxide breaker may include an alkaline peroxide and/or a zinc peroxide. The acid precursor may include polylactic acid and/or polyglycolic acid.

  • Patent number: 7954554
    Abstract: A method of lifting a coiled tubing reel is provided that includes providing a coiled tubing reel including a pair of flanges connected by a core around which a string of coiled tubing is wrapped, and a pair of hubs with each hub connected to a corresponding one of the flanges by a plurality of spokes. The method also includes providing a spreader beam including a pair of support members, and connecting each support member to a corresponding one of the reel hubs. The method further includes lifting the coiled tubing reel by applying a lift force to the spreader beam, such that the load of the lift force is carried by the spreader beam, the reel hubs and at least one of the plurality of spokes.

  • Patent number: 7921758
    Abstract: A technique enables improved performance of oilfield service operations. A protective shield is formed with a portable stand and at least one lightweight impact panel. The one or more lightweight impact panels enable easy movement of the safety shield from one location to another at a given well site or between different well sites, thus affording protection with a minimum of labor and set up time. The safety shield can be used to provide protection during individual operations and/or to segregate and protect independent operations from each other during multiple, simultaneous operations.
