Measurement While Drilling

Achieve accurate directional surveys in any drilling environment

We deliver accurate directional azimuth, inclination, and toolface data in all drilling environments from routine to extreme. Our measurement-while-drilling (MWD) systems leverage several proprietary telemetry methods to reliably transmit data to surface, even in wells subject to heavy vibration, high-lost-circulation-material content, high flow rates, and high doglegs.

Positive-Pulse Telemetry MWD

Acquire directional, gamma ray, and temperature data

Our HyperPulse™ MWD system uses positive-pulse telemetry to deliver directional surveys, gamma ray data, annular-pressure readings, and temperature measurements.

Ultra-HPHT MWD

Trust in real-time data

Our extreme-environment logging services—including the HEL™ hostile-environment-logging and HeatWave™ Extreme services—provide positive mud-pulse telemetry in high-pressure, high-temperature (HPHT) environments up to 30,000 psi (207 MPa) and 392°F (200°C).

Enhanced Electromagnetic (EM) Telemetry

Improve EM signal strength and detection

Our CasingLink™ antenna service enables direct two-way communication regardless of wellbore hydraulics, rig configuration, and salt formations—even in underbalanced drilling and high-fluid-loss zones.

Gyro-While-Drilling Service

Avoid collisions with real-time wellbore positioning data

We enhance drilling performance and safety in magnetic environments with our TrendLineSM gyro-while-drilling service, which provides advanced collision avoidance and real-time wellbore position data.

Electromagnetic Telemetry MWD

Survey without rig hydraulics

The EMpulse™ electromagnetic system transmits bidirectional data by injecting electric current into the formation rather than using mud pulses. This reduces survey time by transmitting data during pumps-off events.
