Embodiment Construction

[0017] see figure 1 , some components of gravel pack apparatus 10 are shown to provide context for the configuration disclosed herein. exist figure 1 In , the cross-coupling connector 12 is shown twice with a spatial separation. The space interval is mainly occupied by the gravel pack screen. Such sieves are known in the prior art and need no explanation here. The screen itself is not shown in the drawings, but those skilled in the art understand that the screen is underneath a screen housing (hereinafter indicated at 42 ) which is shown in the drawings. Although only two connectors 12 are included in the figures, it should be understood that more (or only one) connectors may be used with the gravel pack apparatus 10 . Each connector 12 is shown with a channel 14 for a multi-way tube 16a. The tube 16a advances longitudinally and intersects the multi-way tube 16b in a fluid transferable manner. The multi-way tube 16b is advanced helically along the device 10 until it inte...

Abstract

A gravel pack multi-pathway tube includes a body and a flow passage at the body. Further, the tube includes a projection at the body, the projection receptive to a control line. A gravel packing device component wherein the component includes a shroud, a multi-pathway tube at the shroud, and a projection appurtenant the multi-pathway tube, the projection being receptive to a control line. A method for running and protecting a control line at a gravel pack component, which includes running a component into a wellbore wherein the component includes a shroud, a multi-pathway tube at the shroud, and a projection appurtenant the multi-pathway tube, the projection being receptive to a control line and inserting a control line at the projection.

Description

[0001] Cross-references to related applications [0002] This application claims priority to prior US Provisional Application Serial No. 60 / 643,819 (filed January 14, 2005), the entire disclosure of which is hereby incorporated by reference. Background technique [0003] In oil and gas wells, multi-pass tubing around screen housings is known to convey gravel pack slurry beyond any annular obstructions. Typically, such multi-passage tubes (also known as alternate-passage technology) start to "operate" automatically when an obstruction such as a ring bridge is created. The multi-pass tubing opens into the annulus immediately downstream of the gravel pack packer and provides an alternate path for the slurry flow if the true gravel slurry pressure rises due to an annular obstruction. When there are no annular obstructions, the manifold is naturally bypassed due to the easier flow annulus. [0004] When the multi-pass tube becomes the slurry conduit, the slurry is reintroduced th...
