Electrical Performance
1. Low Capacitance: Critical for maintaining signal integrity over long lengths, especially for analog and high-frequency data transmission. Measured in pF/ft or pF/m.
2. Precise Impedance Matching: Optimized impedance (e.g., 100 Ohms) to match logging tools and surface acquisition systems, minimizing signal reflection and data loss.
3. Effective Shielding: Multiple layers of shielding (e.g., copper braid, foil laminate) to protect against electromagnetic interference (EMI) and crosstalk between conductors, ensuring high-fidelity data.
4. Low Noise: Specialized designs for micro-electrical measurements, reducing inherent noise in the cable itself.
5. Stable Insulation Resistance: High Megohm resistance between conductors and to ground, even after prolonged use in harsh environments.
Environmental & Operational Performance
1. High-Temperature Rating: Ability to operate in extreme downhole temperatures (e.g., 150°C / 302°F, 205°C / 401°F, or even higher).
2. High-Pressure Rating: Constructed to withstand extreme hydrostatic pressures found in deep wells without compromising internal integrity.
3. Chemical & Fluid Resistance: Resistant to degradation from crude oil, saltwater (brine), drilling mud, HS (sour gas), and other corrosive wellbore fluids.
4. Water-Blocking / Impermeability: Filled with gel or use of solid barriers to prevent the migration of moisture along the length of the cable, which can cause signal loss and corrosion.
