Abstract:

A civil aviation communication system has a satellite subsystem including a constellation of satellites. A ground subsystem communicates with the satellite subsystem. The ground subsystem includes a number of networked ground stations at selected locations. An airborne communication subsystem is included in the aircraft. The airborne subsystem transmits to the satellite subsystem in a first frequency band. The airborne subsystem receives transmissions from the satellite subsystem in a second frequency band. The airborne subsystem communicates with a ground based system in a third frequency band. The third frequency band is between the first frequency band and the second frequency band.

International Classification:

E21B 4304

US Classification:

166278, 166227, 166 51

Abstract:

An apparatus and method for gravel packing an interval of a wellbore comprises an outer tubular ( ), which forms a first annulus with the wellbore, and an inner tubular ( ) disposed within the outer tubular ( ) forming a second annulus therebetween. Within the second annulus is an axially extending production pathway ( ) and an axially extending slurry passageway ( ), which is defined between a channel ( ) and the inner tubular ( ). The outer tubular ( ) has outlets ( ) that are substantially aligned with outlets ( ) of the channel ( ). The portions of both the outer and inner tubulars ( ) adjacent the production pathway ( ) have openings ( ). When a fluid slurry containing gravel is injected through the slurry passageway ( ), the fluid slurry exits through the outlets ( ) leaving gravel in the first annulus, thereby gravel packing the interval.

Abstract:

An apparatus and method for gravel packing an interval of a wellbore comprises an outer tubular ( ), which forms a first annulus with the wellbore, and an sand control screen ( ) disposed within the outer tubular ( ) forming a second annulus therebetween. Within the second annulus is an axially extending production pathway ( ) and an axially extending slurry passageway ( ), which is defined between a sheet member ( ) positioned on the sand control screen ( ) and a channel ( ). The outer tubular ( ) has outlets ( ) that are substantially aligned with outlets ( ) of the channel ( ). When a fluid slurry containing gravel is injected through the slurry passageway ( ), the fluid slurry exits through the outlets ( ) leaving gravel in the first annulus, thereby gravel packing the interval.

International Classification:

E21B 4304

US Classification:

166 51, 166278, 166235, 166236

Abstract:

A gravel packing apparatus comprises multiple joints each having substantially the same construction and each having a perforated outer tubular ( ) positioned around a sand control screen ( ) including a slurry passageway ( ) and a production pathway ( ) therebetween. First and second transition members ( ) are disposed at opposite ends of each joint. When two such joints are connected together, the second transition member ( ) of one joint is proximate the first transition member ( ) of the next joint such that a fluid traveling from the slurry passageway ( ) of one joint to the slurry passageway ( ) of the next joint travels from the exterior to the interior of the second transition member ( ) of the one joint and from the interior to the exterior of the first transition member ( ) of the next joint.

US Classification:

166278, 166 51, 166227

Abstract:

An apparatus () and method for treating an interval of a wellbore comprises an outer tubular () disposed within the wellbore. A sand control screen () is disposed within the outer tubular (). A slurry passageway () is formed between the sand control screen () and outer tubular (). In addition, a production pathway () is formed between the sand control screen () and outer tubular (). When the apparatus () is in an operable position, the region between the outer tubular () and the wellbore serves as a primary path for delivery of a fluid slurry, the production pathway () serves as a secondary path for delivery of the fluid slurry if the primary path becomes blocked and the slurry passageway () serves as a tertiary path for delivery of the fluid slurry if the primary and secondary paths become blocked.
