Operating condition of an oil well must be monitored to avoid accidents and to have full control over the production processes in the well.

Oilfield services and geophysical operations are subject to detect, measure and classify vibroacoustic and temperature effects on producting tubings and along the well continuously. Traditionally, memory point sensors have been deployed for such tasks. In recent years, however, the use of optical fiber for distributed acoustic, temperature and today also static-strain sensing has proven effective.

Fiber optic cables and downhole tools can be used in the stages of planning of putting wells into operation, repair of existing wells and regular surveys of suspended wells.

Running cables to power the pump, collect information from point sensors and provide distributed fiber optic monitoring is a technical challenge, limited by the dynamics of the well and subsurface equipment.

WB cables can be used for monitoring the well conditions cost-effectively and efficiently.

To solve this challenge, Wires&Bytes have developed a range of downhole cables that combine several functions at once:

• power delivery to and signals transmission from downhole tools;
• continuous distributed monitoring along the well and its horizontal sections;
• reagent delivery and/or provision of a hydraulic control line to the submersible downhole equipment.

Wires&Bytes offer both permanent and retrievable downhole cables for logging surveys and service operations for downhole installations:

• fixing on the tubing (mostly designs with rectangular cross-section);
• retrievable cables with additional armoring for protection against external mechanical impacts;
• coiled tubing (CT);
• permanent installation in wellbore concrete casing.

Why use fiber optic sensor cables?

Wellbore fiber optic monitoring technologies using DAS, DTS and DSS measurement equipment turns cables into long-reach subsurface antennas helping to reduce survey time because distributed monitoring provides simultaneous temperature and acoustic measurements along the entire well, which is critical for studying the dynamics of rapidly evolving processes and changing events. WB hybrid cables allow different types of downhole tools to be connected to it and fiber optics for monitoring.
