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.
Accurately place wells with real-time resistivity data
Azimuthal Resistivity Logging
Our unique GuideWave® resistivity tool provides deep-reading azimuthal measurements with 360° boundary detection to enable proactive well placement. Now enhanced by the GuideWave CLEAR service, this solution delivers real-time multi-boundary inversion and resistivity modeling—extending visibility more than 40 feet around the wellbore. In complex geological applications, the service increases reservoir contact, mitigates drilling hazards, avoids fluid contacts, and minimizes sidetracks with greater confidence and precision.
