Resistivity Logging

Detect boundaries and measure water saturation while drilling

Our resistivity services provide an industry-leading array of measurements. Using the resistivity measurement―fundamental to any formation evaluation program―our LWD experts can help you determine hydrocarbons in place, calculate water saturation, correlate against the reservoir model, evaluate pore pressure, and guide final well placement.

Standard Resistivity Logging

Acquire resistivity logs in any mud system

Our MFR (multi-frequency resistivity) sensor provides symmetrically compensated phase-shift and attenuation measurements at two frequencies and three spacings. This service delivers 12 fully compensated curves even at high formation resistivities.

Azimuthal Resistivity Logging

Accurately place wells with real-time resistivity data

Our unique GuideWave® resistivity tool provides deep-reading azimuthal measurements with 360° boundary detection to enable proactive geosteering. In complex drilling applications, the tool increases reservoir contact, mitigates drilling hazards, avoids fluid contacts, and minimizes sidetracks.

Ultra-HPHT Resistivity Logging

Acquire resistivity logs in extreme temperatures

Our HeatWave® Extreme resistivity service delivers formation-resistivity measurements in high-pressure, high-temperature (HPHT) environments up to 30,000 psi (206.8 MPa) and 392°F (200°C).
