Abstract

A non-rotating connection for tubular conduits in a well bore well bore includes fiber optic, electrical, or hydraulic connectors. The non-rotating connection is placed between a packer and instrumented screen joints. The non-rotating connection anchors and seals between the tubulars, and connects and protects the fiber optic, electrical, or hydraulic connectors from erosion or damage.

Title: Gravel Pack Make-Up Sub with Integral Electrical and Optical Connectors

Abstract


A non-rotating connection for tubular conduits in a well bore well bore includes fiber optic, electrical, or hydraulic connectors. The non-rotating connection is placed between a packer and instrumented screen joints. The non-rotating connection anchors and seals between the tubulars, and connects and protects the fiber optic, electrical, or hydraulic connectors from erosion or damage.

Description of the Invention


This invention is used with gravel pack completions that monitor the temperature across the sand face with either fiber optics or electrical gages. Fiber optics or electrical gages are placed on sand screens to detect water break through as water causes a change in temperature of the produced fluids.

A make-up sub is needed to align the fiber optic cable with the cable protectors between the packer and the screens. This invention combines the make-up sub, dry mates, and cable protectors into a single device.

The purpose of a make-up sub is to provide a non-rotating connection below the packer. The design varies a bit from size to size, but is generally made of a top sub, bottom sub, cap, and a seal as shown in the sketch below.

The fiber optic or electrical dry mates are installed the top sub and bottom sub as shown. One set of connectors is shown, however this design is concentric so any number of connectors can be added. The top sub seals inside the bottom sub wit...
