  • Patent number: 10633945
    Abstract: A molded tool is formed from a compression mold material and a corresponding method of manufacture is disclosed. The molded tool has a first end, a second end separated from the first end by a sidewall formed from a heat-sensitive polymeric matrix. The sidewall has an interior surface with a first strength and an exterior surface with a second strength, the first strength being greater than the second strength. Further, the molded tool is formed by a method that includes exerting an expansive force within an interior of the compression mold material, the expansive force having a directional vector along the central axis.
    Type: Grant

  • Patent number: 8839869
    Abstract: A downhole tool for use in a well is configurable as a frac plug, a caged ball frac plug or a bridge plug. The tool has a mandrel with a threaded neck. The mandrel has an expandable sealing element disposed thereabout. An adapter, which may be selected from multiple configurations of adapters, is threaded to the neck of the mandrel. The adapter may comprise a sleeve, or a cap with one open end and one closed end. The adapter has threads on an outer surface thereof to which a threaded setting mandrel may be attached. The setting mandrel when actuated will move the tool to a set position in the well and once the tool is moved to the set position the threads on the adapter will shear so that the setting mandrel may be retrieved. The tool will thus remain in the hole and will act as either a frac plug, a caged ball frac plug or a bridge plug depending upon the configuration of the selected adapter.
