Filed:

Nov 30, 1995

Appl. No.:

8/565536

Inventors:

David Speed - Dallas TX
Robert Sharum - Garland TX

Assignee:

CAMCO International Inc. - Houston TX

International Classification:

E21B 2303

US Classification:

1661175

Abstract:

An improved side pocket mandrel having an orientation housing, which in turn has an orienting slot and guide surfaces integrally formed with the orientation housing. The orientation housing is preferably manufactured by machining out of a single piece of metal. The orientation housing is then welded onto the remainder of the side pocket mandrel.

Abstract:

Apparatus and methods for conducting well-related fluids are disclosed. The apparatus and methods may be used to mitigate erosion of fluid handling equipment by fluids associated with hydrocarbon wells. An exemplary apparatus comprises: an upstream conduit including an upstream fluid passage for receiving and conducting well-related fluid; a choke member including a choke fluid passage; and a downstream conduit including a downstream fluid passage in fluid communication with the upstream fluid passage via the choke fluid passage. A cross-sectional area of the downstream passage may be greater than a cross-sectional area of the upstream passage to allow expansion of the fluids passing through the choke such that the average velocity of such fluids may not exceed a threshold velocity selected to mitigate erosion of the downstream conduit.
