A screen system formed of a first screen sub and a second screen sub joined by a connector sub. The connector sub includes (i) a pipe coupling assembly connecting the base pipes of the first and second screen subs; (ii) a substantially impermeable shroud formed around the pipe coupling assembly and creating a connector annulus between the shroud and pipe coupling assembly; and (iii) end rings including a substantially annular flow passage connecting the first and second screen annuluses to the connector annulus.

Provided is an improved bypass durable dart plunger that descends faster in a hydrocarbon well, is capable of lifting more fluids and has a durable and replaceable clutch assembly. The various components of the durable dart plunger includes a sleeve, a dart body with a one or more flow ports (chokes) cut at right angles through the dart body, a pin and a replaceable clutch assembly (also referred to a retention assembly). The chokes can be of varying sizes. In one embodiment, the clutch assembly includes a plurality of clutch mechanisms wherein each mechanism includes a ball, a socket screw and a resilient spacer.


A production casing string including a plurality of propellant sleeves positioned on an exterior of the production casing string, and each propellant sleeve includes a firing mechanism and a firing sleeve for selectively covering and uncovering the firing mechanism. The casing string also includes an identifiable marker associated with each propellant sleeve and at least one selective bi-directional valve assembly associated with each propellant sleeve.

A screen system having a first screen sub including a first base pipe wrapped with a first screen section; a second screen sub including a second base pipe wrapped with a second screen section; and a pipe coupling assembly joining the first and second base pipes. A section of filter material extends between the first and second screen sections, and extends over the pipe coupling assembly, thereby forming an annular flow path from the first screen section to the second screen section over the pipe coupling assembly.


Patent
Superior Services | Date: 2015-10-05

A toe valve having an outer tubular member, including at least one outer flow port, and an inner tubular member positioned at least partially within the outer tubular member and including a central flow passage. An indexing mechanism is positioned within the outer tubular member and there is a flow path allowing fluid pressure from the central passage to act against a first side of the indexing mechanism. A biasing device acts on a second side of the indexing mechanism and the indexing mechanism is configured to allow communication between the central flow passage and the outer flow port after the indexing mechanism is subject to a plurality of pressure cycles within the central flow passage.

A flow control device formed of a tubular housing having a circumferential wall and a central passage. A plurality of flow apertures are formed through a section of the circumferential wall and a dissolvable material is positioned to block flow through the flow apertures. A closing sleeve capable of moving into a position to block flow through the flow apertures is also positioned within the housing.


Patent
Superior Services and A O International II Inc. | Date: 2015-03-25

A propellant tool for use in a hydrocarbon bearing formation. The tool includes a tubular body having a connector on each end for connection with other tubular members within a tubular string. A coded marker is positioned on the tubular body and a propellant chamber is positioned on an outside surface of the tubular body. A propellant ignition mechanism positioned on the tubular body for igniting the propellant in the propellant chamber.

An object counting mechanism for a downhole tool which includes a tool housing having a central passage and a seat configured to selectively catch an object passing through the central passage. An activating mechanism is configured to move the seat from a first state allowing the object to pass through the seat into a second state for catching the object on the seat. A rotating sleeve causes the activating mechanism to move the seat into the second state after a given degree of rotation of the rotating sleeve. At least one contact surface is spaced apart from the seat and positioned to engage the object passing through the central passage, thereby effecting a limited rotation of the rotating sleeve at each passage of an object.
