    摘要: Perforating devices, temporary dissolvable plugs, and dissolvable indicator devices for downhole tools all having at least one tracer are disclosed. Upon detonation of the perforating charge, dissolution of the temporary plug, or actuation of a downhole tool, the tracer is released and carried to the surface as an indictor to the operators of the well that the perforating charge detonated, the temporary plug dissolved, or the downhole tool actuated.

    摘要: A fracturing operation is done in open hole. The annular space is spanned by telescoping members that are located behind isolation valves. A given bank of telescoping members can be uncovered and the telescoping members extended to span the annular space and engage the formation in a sealing manner. Pressurized fracturing fluid can be pumped through the telescoped passages and the portion of the desired formation fractured. In a proper formation, cementing is not needed to maintain wellbore integrity. In formations that need annular space isolation, the string in a preferred embodiment can have an external material that grows to seal the annular space in lieu of a traditional cementing operation.

    摘要: Devices and methods for setting a packer inside a wellbore with little appreciable reduction of the useable area of the wellbore. The outer casing or liner of the wellbore contains one or more integrated casing coupler joints having an increased diameter chamber portion. A large bore packing element is carried within the increased diameter chamber portion. The packing element may be selectively actuated to form a seal against an interior tubular member. Because the packing element is located within the chamber portion of the casing coupler, the packer may be set while saving useable cross-sectional area within the casing.
