A downhole tool and method of operation thereof is provided. The downhole tool may be configured to permit fluid communication between a combined flowbore of the casing string and the downhole tool and the subterranean formation or wellbore, or both, after a pressure test has been completed, a second threshold pressure is reached or applied, and a third threshold pressure has been applied to the downhole tool.

Downhole completion tool

Goggles for use in water that are configured to guide a person along predetermined courses. The goggles can have a pair of indicators that can be in communication with a microprocessor. The microprocessor can actuate the indicators selectively to guide a person wearing the goggles along a predetermined course.

Goggles for use in water

A downhole tool and method for performing to provide a flow path from an inner bore thereof to a wellbore annulus, wherein the flow path is provided upon the application of pressure.

Downhole tool

A clamping apparatus allowing a downhole line to be fed between downhole tubular members. The clamping apparatus can include a first and second half, each including: support arms with inner surfaces, connecting walls, and grips. The first and second halves can be selectively connectable. The clamping apparatus can include handles, hinges, and latches. A system for feeding a downhole line between an outer tubular member and an inner tubular member can include an outer tubular member disposed about an inner tubular member, wherein the clamping apparatus is disposed about the inner tubular member.

Control line feed through clamp

A downhole shifting mechanism having an inner tubular member, an outer tubular member, a piston, a first set of teeth, a sliding block, a body lock ring, a first flow path, and a second flow path is described herein. A downhole assembly can include the downhole shifting mechanism with a downhole tool connected to a second end of the downhole shifting mechanism. Also described is a method for shifting a downhole tool disposed within a wellbore.

Downhole tool shifting mechanism and method for shifting a downhole tool

A method for feeding a downhole line between two tubulars is provided. The method can include connecting a clamping apparatus about a first tubular member. The method can include supporting a second tubular member with a support surface of the clamping apparatus, feeding a downhole line through a pass through channel formed between the clamping apparatus and a tubular member, and communicating the downhole line with a tool. The clamping apparatus can include two halves, each with support arms, connecting walls, and grips.

Method for feeding control lines for drilling or workovers

One or more embodiments of a selectively openable and closable downhole tool. The wherein, the downhole tool can include an outer tubular member having an annulus port formed therethrough. The downhole tool can also include an inner tubular member. The inner tubular member can include an inner port. The inner port and annulus port can be selectively aligned to form a flow path therethrough by moving the inner tubular member relative to the outer tubular member. The downhole tool can also include a logic drum configured to selectively move the inner tubular member. The downhole tool can also include a piston assembly configured to move the logic drum.

System for controlling hydrocarbon bearing zones using a selectively openable and closable downhole tool

A formation saver sub or pump out sub incorporating an anti-surge feature. The sub includes a body, a mandrel, a piston (or an annulus fluid pressure chamber and a tubular pressure chamber), a sleeve, a spring, a releasable seat, and a plug. The plug and seat are released from the sub when one or more dogs releasably positioning the seat in the mandrel bore disengages from the seat due to a bleed off of fluid pressure in the well bore.

Formation saver sub and method

A multiple-positioning mechanical shifting system including for used in hydrocarbon wells. The system includes a shifting tool capable of selectively positioning a mechanical sliding sleeve valve in multiple operational positions that varying the flow rate and/or volume of tubing string fluid flowing to the well annulus. The system also includes a multiple position mechanical choke valve. A method of operating the mechanical choke valve using the shifting tool is described.

Multiple-positioning mechanical shifting system and method

A bypass device for bypassing a hydraulic piston in a wellbore with an outer tubular body. The outer tubular body can have a fluid control manifold. The fluid control manifold can have two control paths, two high pressure fluid paths, and two valves connecting with two high pressure fluid connecting paths. An inner tubular body can be disposed within the outer tubular body, and a piston chamber can be disposed between the inner tubular body and the outer tubular body. The piston chamber can include two piston chamber sections separated by a hydraulic piston.

Bypass device for wellbores

A coiled tubing multi-zone frac system for fracing a formation adjacent a well using a sliding sleeve and erodible jets. Erodible jets can provide a means for perforating, fracing and flowing the well which takes the place of two separate tools that are otherwise needed to cause a well to flow, namely, this single tool replaces a perforating gun, a production sleeve.

Coiled tubing multi-zone jet frac system

A downhole filter with a filter housing having a top filter and a bottom filter disposed therein. The filter housing can be in fluid communication with each filter. Each filter can be in fluid communication with a burst disk housing having a burst disk module and a burst disk. Each burst disk housing can be in fluid communication with the filter housing. Fluid can flow through the filter housing and through the filter. When a filter is clogged, the fluid can burst a burst disk, thereby bypassing the filter. The downhole filter can include a middle sub in fluid communication with the top filter and a second portion of the filter housing. The middle sub can threadably engage a bottom burst disk housing.
