Wireline cables for downhole logging operations, delivering reliable power and data in high-pressure, high-temperature wells.
Rochester Cable has supplied wireline cables to logging service providers for more than 60 years. Our designs combine mechanical strength, thermal performance, and stable electrical or optical characteristics, enabling tools to be deployed repeatedly in challenging wells.
Mechanical strength and handling
Constructions designed to manage tensile loads, drum winding, sheave contact, and repeated runs in vertical and deviated wells.
High-temperature performance
Cables and material systems designed to support performance in elevated downhole temperatures, including high-temperature cased-hole and geothermal applications.
Signal and data integrity
Single-conductor, multi-conductor, and fiber optic or hybrid wireline options that support logging data, tool control, and advanced diagnostics.
Application-specific variants
Cased-hole, open-hole, sour-service/H₂S-resistant, geothermal, fiber-optic and hybrid, greaseless designs, and custom wireline solutions can be reviewed to match service requirements and tool designs.
Rochester Cable supports a range of wireline cable families for demanding downhole logging and well service applications.
Rochester Cable offers multiple cable sizes and constructions for cased-hole operations, with temperature ratings from 300°F to 600°F for standard through high-temperature applications.
Open-hole wireline cables are designed for advanced formation evaluation and applications that require higher power, greater signal capacity, or both. These cables support complex logging suites, imaging tools, and multi-sensor systems.
Rochester Cable’s H₂S-resistant wireline cables are built for corrosive environments and regulated sour-service applications where environmental resistance is critical.
Geothermal wireline cables are designed for extreme-temperature environments where heat and operating stress place additional demands on cable performance. Our geothermal cable designs are rated up to 610°F for reliable operation in extreme-heat applications.
Fiber optic and hybrid wireline cables are built for applications that require real-time data transmission, advanced diagnostics, or electrical-and-fiber combinations alongside the mechanical strength needed for harsh downhole service.
VIRIDIS™ wireline cables provide a cleaner, greaseless alternative to traditional exposed-armor designs. VIRIDIS™ is designed to reduce grease requirements, support cleaner handling, and improve field efficiency in suitable wireline applications.
When standard constructions are not the right fit, Rochester Cable can support custom wireline cable designs tailored around specific tools, well conditions, and operating requirements.
Formation evaluation logging tools measure properties such as resistivity, porosity, and lithology to characterize the reservoir. Their performance depends on clean, continuous transmission of data from the tool to surface acquisition systems.
What our cables deliver for formation evaluation:
Well integrity logging is used to detect casing, cement, and completion issues over the life of the well. Logging cables must support multiple runs and changing conditions as the well ages.
What our cables deliver for integrity analysis:
Production logging tools measure flow profiles and fluid behavior to help optimize production. Cable performance influences both tool conveyance and data quality.
What our cables deliver for production logging:
Completion and intervention operations can require specialized tools conveyed on wireline to set equipment, perform diagnostic work, or support remedial actions. Cables must handle these operations while still providing reliable power and communication.
