Logging Optical Cable Specifications and Models

Logging optical cables include wireline, slickline, and permanently installed downhole fiber optic cables with various armored and metal tube constructions for harsh environments.Types of Logging Optical CablesWireline Logging CablesDesigned for deployment in oil and gas wells for real-time data acquisition.Typically include fiber in metal tubes (FIMTs) for hermeticity, crush resistance, and corrosion protection.Can be wire-armored to improve tensile strength and handling characteristics.Used for distributed temperature sensing (DTS), distributed acoustic sensing (DAS), and telemetry to point sensors such as pressure or strain gauges .Slickline Logging CablesSlimmer, flexible cables for well intervention and logging operations.Often used in environments where minimal diameter is critical.Can include single or multiple fibers in protective metal tubes with optional polymer jackets .Permanently Installed Downhole CablesCemented behind casing or strapped to production tubing.Provide long-term monitoring of temperature, strain, and acoustic signals.Construction options include stainless steel FIMTs, wire armor, and outer polymer jackets for enhanced durability .Construction VariantsFiber in Metal Tubes (FIMTs): Available in different sizes, wall thicknesses, and metal types. Provides hermetic sealing and mechanical protection.Wire Armored FIMTs: Adds high-strength stranded wire over the FIMT for improved crush resistance and tensile strength.Outer Polymer Jackets: Optional for additional environmental protection, chemical resistance, and abrasion resistance.Tactical or Re-deployable Cables: Designed for repeated deployment in harsh or industrial environments .ApplicationsOil and gas wells (DTS, DAS, pressure, and strain sensing)Pipelines and LNG facilitiesIndustrial monitoring (power cables, dams, nuclear, coal, or gas plants)Hydrological studies and subsea monitoringTelemetry for fiber Bragg gratings (FBGs) and point sensors Notable Manufacturers and CatalogsOptronicsPlus: Offers pigtail and tight-buffered fiber optic cables with singlemode and multimode options, suitable for logging terminations and patch panels .Belden: Provides a wide range of fiber optic constructions, including market-specific approvals for marine and wind applications .Proterial Cable America: Offers high-performance fiber optic cables with open system architecture for verified connectivity and lifetime warranty .Fibercore: Specializes in downhole fiber optic cables with FIMT and wire-armored constructions for permanent or tactical installations .
