Abstract

An example device in accordance with an aspect of the present disclosure includes a splice housing body comprising a raceway within which optical fibers can be positioned, at least one port through the splice housing body to which a pressure fitting for optical fiber can be mounted, a base to which the splice housing body may be removably attached, and a port in one of the splice housing body or base for inserting fluid in the splice housing body.

First claim

That which is claimed is:

1 . A cable splice housing assembly for use in a well, comprising:
(a) a splice housing body comprising a raceway within which optical fibers can be positioned, (b) at least one port through the splice housing body to which a pressure fitting for optical fiber can be mounted, (c) a base to which the splice housing body may be removably attached and (d) a port in one of the splice housing body or base for inserting fluid in the splice housing body.

2 . The cable splice housing assembly of claim 1 , wherein the base is an integral part of a mandrel.

3 . The cable splice housing assembly of claim 1 , wherein the raceway is oblong or oval.

4 . The cable splice housing assembly of claim 1 wherein the splice housing body has surface having the same shape as a mandrel surface to which the splice housing body may be attached.

5 . The cable splice housing assembly of claim 4 , wherein the mandrel contact surface is curved.

6 . The cable splice housing assembly of claim 4 , wherein the mandrel contact surface is flat.

7 . The cable splice housing assembly of claim 6 , wherein the mandrel serves as a base for the splice housing body when the splice housing body is secured to the mandrel.

8 . The cable splice housing assembly of claim 7 , wherein the splice housing body is secured to the mandrel with threaded fasteners that pass through the splice housing body and into the mandrel.

9 . The cable splice housing assembly of claim 1 , further comprising a plurality of ports at which compression fittings may be attached for introducing optical fiber cable into the splice housing body.

10 . The cable splice housing assembly of claim 1 , further comprising at least one port to which at least one sensor may be attached.

11 . The cable splice housing assembly of claim 1 , further comprising a cover positionable between the splice housing body and the base.

12 . The cable splice housing assembly of claim 1 , further comprising a seal-receiving groove in one of the splice housing body or the base.

13 . The cable splice housing assembly of claim 12 , further comprising two C-seals in the groove.

14 . The cable splice housing assembly of claim 11 , further comprising a plurality of threaded fasteners for attachment of the base to the splice housing body.

15 . The cable splice housing assembly of claim 1 , further comprising collar engaging structure on the splice housing base and at least one collar for securing the splice housing body and base to a casing.

16 . A cable splice housing assembly, comprising:
(a) a splice housing body:
(i) comprising a generally flat and generally oval or oblong cavity for receiving cable and cable splices,
(ii) penetrated by:
(1) at least two cable or sensor ports at which compression fittings can be attached and
(2) one fill port, and

(iii) having a seal-receiving groove around the cavity,
(b) a base for the splice housing body, wherein the base is penetrated by at least two holes through which threaded fasteners may pass into the splice housing body for securing the base to the splice housing body.

17 . The cable splice housing assembly of claim 16 , further comprising at least one port in the splice housing body to which a compression fitting may be attached for passage of a sensor cable into the cable splice housing assembly.

18 . The cable splice housing assembly of claim 16 , further comprising at least one collar for securing the cable splice housing assembly to a mandrel.

19 . The cable splice housing assembly of claim 16 , further comprising a holder for sensors mounted adjacent to the cable splice housing body.

20 . A modular cable splice housing assembly for use in a well, comprising:
(a) a splice housing assembly comprising a raceway within which optical fibers can be positioned, and (b) at least one end ring for securing the splice housing assembly to well casing.
