Embodiment Construction

[0028] figure 1 Illustrated is a cross-sectional view of an example of a hermetically sealed fiber optic catheter 100 suitable for use in accordance with one or more embodiments of the present disclosure. figure 1The illustrated example of a hermetically sealed fiber optic conduit 100 illustrates twenty optical fibers 101 carried within the interior 105 of a stainless steel tube 106 with a watertight outer layer 108 . More or fewer than twenty optical fibers may be accommodated within the tightly sealed fiber optic conduit 100 . Embodiments are not limited to the numbers shown in this example. In this example, a stainless steel tube with a watertight outer layer 108 creates a "tight seal" for the tightly sealed fiber optic conduit 100 . In other words, the optical fiber 101 can be protected by hermetically sealing the optical fiber 101 in the stainless steel tube 106 and the waterproof outer layer 108 .

[0029] Each optical fiber 101 within the tightly sealed fiber optic c...

Abstract

The invention relates to floodable optical apparatus, methods and systems. According to one example, a floodable sensor station is coupled to an optical cable. The optical cable may be floodable. The floodable sensor station may connect floodable optical cables as part of a permanent reservoir monitoring system. The floodable optical cable may house a plurality of floodable optical fiber conduits. The floodable sensor station may be pressure-balanced with its surrounding environment in high-pressure marine depths of 1500 meters or more.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application No. 62 / 059,271, filed October 3, 2014, which is incorporated by reference. Background technique [0003] Fiber optics are commonly used to transmit data at high bandwidths. Investments in developing fiber optic communication technology have focused on making such bandwidth available over long distances. Long distances further require the production of cables that are both affordable and robust. [0004] Fiber optic cables typically must withstand not only the damage associated with shipping and installation, but also the potential effects of aging and long-term exposure to factors including environmental pollutants. One such example in the marine environment is known as the hydrogen darkening effect. After long exposure times, whether caused by corrosion, biological processes, or other ocean-related causes, hydrogen can diffuse into the core of the fiber a...
