Specialty high performance cables engineered for harsh environments


In many applications, the optical fiber must be contained within a cable structure to ensure it survives the environment in which it is designed to be deployed. The best fiber in the World cannot overcome an improperly designed or manufactured cable. Fibercore brings over 20 years of cable design knowledge and manufacturing expertise to create cable designs that are customized to the rigors of specific environments. Fibercore specializes in the harshest of environments, ranging from cryogenic applications to the some of the hottest enhanced oil recovery wells. Fibercore extends to a network of manufacturing facilities, each with a particular strength and are not limited to in-house capabilities. For the most challenging applications, Fibercore delivers the best solution.

 

Goals in Designing Fiber Optic Cables

• Enable deployment of optical fiber
• Preserving optical transmission characteristics
• Optimizing the attribute to be measured
• Protecting from ecological/mechanical stress
• Providing reliable transmission throughout design life of cable

 

Cable Applications

Oil&Gas
Fiber optics are used for measuring a variety of attributes in an oil or gas well including: distributed temperature, distributed acoustic energy, and strain. This is also used alongside telemetry for fiber optic point sensors, such as pressure sensors and fiber Bragg gratings (FBGs). The types of cables used in the industry include: permanently installed fiber optic cables, logging cables (both wireline and slickline) and surface cables. With the information these types of cables can yield, the reservoir engineer can optimize the production from the oil or gas field thus improving the return on investment.


Industrial Sensing
There are many environments where knowledge of the temperature, strain, acoustic energy or other attributes is beneficial to the user. Applications such as pipelines, LNG facilities, waterways, industrial facilities, power cables, dams, power generation facilities like nuclear, coal or gas have used fiber optics successfully to gain insight into their operation. Each of these applications would use slightly different cable structures to provide not only the robustness necessary for long term use, but also to optimize the measurement of the attribute desired.

Downhole Fiber Optic Cable



Downhole Fiber Optic Cable

Fibercore offers a range of designs for downhole fiber optic cable to meet the specific requirements of your oil or gas well. These types of cables are permanently installed either cemented in behind the casing or strapped to the production tubing. The optical fibers can be used to sense temperature and listen to well bore activities along the entire length of the cable and can be used for telemetry to point fiber optic sensors, such as pressure sensors and strain sensors.

This information provides key data to the reservoir engineer to better manage both the well and the reservoir. Design variables include type and number of optical fibers, metal types to deal with different corrosive environments, thicknesses of metal tubes to handle different pressure requirements and outer encapsulations for improved handling and abrasion resistance.
