Embodiment Construction

[0102] Novel apparatus, systems and methods relating to downhole tools that may be used in wellbore operations are disclosed herein, the details of which are described herein.

[0103] A downhole tool according to embodiments disclosed herein may include one or more anchor blocks, one or more compression cones engageable with the blocks, and a compressible sealing element disposed therebetween, all of which Can be configured or mounted around a mandrel. The mandrel may include a flow bore that opens into the end of the tool and extends to the opposite end of the tool. In an embodiment, the downhole tool may be a frac plug or a bridge plug. Accordingly, the downhole tool may be suitable for use in fracturing operations. In an exemplary embodiment, the downhole tool may be a composite frac plug made of a drillable material suitable for use in a vertical or horizontal wellbore.

[0104] A downhole tool usable for an isolated section of a wellbore may include a mandrel having a...

Abstract

A downhole tool has a mandrel with one or more sets of threads; a fingered member disposed around the mandrel; a first conical shaped member also disposed around the mandrel; and an insert positionedbetween the fingered member and the first conical member, and in proximity with an end of the fingered member, wherein the fingered member comprises a plurality of fingers configured to move from a first position to a second position.

Description

technical field [0001] The present invention generally relates to tools for use in oil and gas wellbores. More specifically, the present invention relates to downhole tools operable into a wellbore and useful for wellbore isolation, and systems and methods related thereto. In certain embodiments, the tool may be a composite plug made of a drillable material. Background technique [0002] An oil or gas well includes a borehole extending into the formation at a depth below the surface (eg, the earth's surface) and is usually lined with tubulars (eg, casing) to increase the strength of the well. Many commercially available hydrocarbon sources exist in "tight" reservoirs, meaning that the hydrocarbon products of interest may not be readily extracted. The surrounding formations (e.g., shale) of these reservoirs are generally less permeable, and hydrocarbons are produced in commercial quantities from such formations without the use of boreholes associated with fracturing operati...
