Abstract: A wellbore isolation device comprising: one or more materials, wherein the one or more materials degrade after contact with a fluid; and a non-metallic coating, wherein the coating covers the one or more materials of the wellbore isolation device, and wherein the coating partially or wholly degrades after contact with a wellbore fluid. A method of removing the wellbore isolation device comprising: degrading the coating via contact with a wellbore fluid; and contacting the portion of the wellbore isolation device with a fluid, wherein the portion of the wellbore isolation device comprises one or more materials that degrade after contact with the fluid.

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.

Abstract: A downhole tool for use in a well has a mandrel with an expandable sealing element disposed thereabout. The mandrel has a head portion threadedly connected thereto. A shoulder in the head portion and an upper end of the mandrel define an annular space. A sleeve with a bore therethrough may be positioned in the annular space. The head portion may be removed and a solid plug installed so that it fits within the annular space and so that the downhole tool will act as a bridge plug. The downhole tool has slip rings made up of a plurality of individual slip segments that are adhesively bonded to one another at the sides thereof.

Abstract: A downhole tool that is capable of isolating communication pressure from below the set downhole tool, and is capable of being converted to a frac plug is provided. The downhole tool includes a packer with a ball seat defined therein. A plug is disposed at a lower end of the downhole tool to isolate the upper well from the lower well. A sealing ball is carried with the packer into the well by a setting tool. The movement of the sealing ball away from the ball seat is limited by isolation of the sealing ball from the lower well. A rod is disposed through the downhole tool contacting the plug. The rod is partially disposed in the ball seat, preventing the sealing ball from sealing. When the packer is set, flow within the well is isolated, thereby allowing treatment of the well above the packer. With the application of sufficient pressure, the sealing ball applies force to the rod which shears the plug from within the tool. The tool is converted to a standard frac plug.

Abstract: A hydraulic setting tool for packers capable of mechanically setting the packer and opening a valve in the packer in one trip. The tool comprises an outer sleeve and an inner mandrel coaxially disposed within the outer sleeve and adapted to move axially relative to the outer sleeve. The tool further comprises three locking mechnisms that unlock under different fluid pressure loads. Two of the locking mechanisms lock the inner mandrel to the outer sleeve in a run-in position. Once a sufficient fluid pressure has been reached to unlock both of these locking mechanisms, the inner mandrel moves upward relative to the outer sleeve to set the packer. A spring forces the inner mandrel into a third position relative to the outer sleeve, which is maintained by the third locking mechanism. This third position is used to open the packer valve.
