Filed:

Dec 10, 2004

Appl. No.:

11/010116

Inventors:

Radovan Rolovic - Cheltenham, GB
Stephen D. Hill - Pearland TX, US
Frank Espinosa - Richmond TX, US
John R. Lovell - Houston TX, US

Assignee:

Schlumberger Technology Corporation - Sugar Land TX

International Classification:

E21B 21/00

US Classification:

166312, 166 66, 166222

Abstract:

Apparatus and methods for measuring solids in wellbore that include a bottom hole assembly having a sensor to measuring a characteristic indicative of solids in the wellbore. The measurement may be used to measure solids or solids suspended in fluid flow. The invention is useful for use in wellbore cleanouts. A computer model may be used and updated based on the measured characteristic. The input of measured characteristic and the updating of the computer model may be performed in real time whilst the wellbore cleanout operation is ongoing.

John R. White - Wadsworth OH

Assignee:

The Goodyear Tire & Rubber Company - Akron OH

International Classification:

B29D 3022

US Classification:

156415

Abstract:

A segmental drum (10) has spaced-apart inflatable turnup bladders (24) for folding each edge (28) of a belt (30) applied to the drum (10). The spacing of the bladders (24) is adjustable by axial movement in opposite directions of central hub assemblies (42,44) threaded on screws (76). Fine adjustment of the spacing to straigten the fold line (32) of each bladder (24) is provided by axial adjustment of rigid polyurethane bladder support brackets (18) connected to the central hub assemblies (42,44). Radial expansion of the segments (16) is provided by links (84) between each of the segments (16) and spaced drum expanding hub assemblies (86,88) threaded on a drum control screw (96). A molded central filler block (62) of rigid polyurethane is mounted on each segment (16) to fill the space between the bladder support brackets (18). A molded center sleeve (72) of stretchable resilient polyurethane material is positioned over the central filler blocks (62) of the segments (16) and may have a contoured outer surface (74) for shaping the belt (30).

Assignee:

The Goodyear Tire & Rubber Company - Akron OH

International Classification:

B60C 902

US Classification:

152358

Abstract:

A tire having a reinforcing sheet of tubular knit material stretchable during shaping into a toroidal form. The knit material provides openings for striking through of the liquid reaction mixture of elastomer forming material used in molding the tire. The sheet of knit material may be folded over spaced-apart bead rings and overlapped to provide multiple layers. The tire is molded on a core supporting the reinforcing sheet and bead rings with the strands of the knit material straightened out and in tension at the time of cure.

Assignee:

The Goodyear Tire & Rubber Company - Akron OH

International Classification:

B29C 500
B29G 300

US Classification:

264102

Abstract:

This invention relates to a method of forming shaped articles utilizing liquid functional group polymers compounded with suitable compounding agents to produce mixtures of extremely viscous nature and moving these viscous mixtures to a shaping device without the entrapment of air.

International Classification:

B29D 3072
B05D 126

US Classification:

156356

Abstract:

A cured rubber tire has adhered thereto a layer of heated and mixed, productive urethane composition fluid sidewall material which has been flowed from a nozzle into a groove in the sidewall of a shaped tire. The tire is rotated under the nozzle a distance equal to the circumferential length of the groove so that the ends of the layer may be joined after which the flow of productive urethane composition sidewall material is terminated.

International Classification:

E21B 47/06
E21B 43/14

Abstract:

Methods for correcting temperatures measured in producing wells are provided. In one embodiment, a method includes receiving formation fluid within a completion string in a well, wherein the formation fluid passes from a formation and radially into the completion string through at least one opening in the completion string. The method also includes measuring temperatures outside the completion string at multiple depths in the well at which the formation fluid passes from the formation and radially into the completion string. The temperatures measured outside the completion string at the multiple depths in the well are converted into axial temperatures inside the completion string at the multiple depths. Additional systems, devices, and methods are also disclosed.
