Directional Drilling

Downhole hydraulic motors driven by drilling-fluid flow through a Moineau power section to rotate the bit independently of the drill string, typically fitted with an adjustable bent housing to create the deflection needed for steering.

Tools that steer the bit while the entire drill string continues to rotate, using either push-the-bit pads or point-the-bit shaft deflection to deliver smoother, faster, and more accurate trajectories in extended-reach and horizontal wells.

Measurement-while-drilling tools that survey hole inclination, azimuth, and toolface and transmit the data uphole, most commonly by mud-pulse telemetry or by electromagnetic (EM) telemetry where mud-pulse is impractical, such as in air-drilled or underbalanced wells.

Logging-while-drilling sensors that measure formation properties such as gamma ray, resistivity, density, and porosity at the bit to support real-time geosteering and reservoir placement of the wellbore.

PDC and roller-cone bits with steerability-optimized cutting structures and gauge designs for directional, horizontal, and HDD applications, including short-gauge bits suited to high build rates.

North-seeking and continuous gyro instruments used to obtain wellbore surveys independent of the Earth's magnetic field, applied for surface reference, anti-collision in congested fields, and surveying inside magnetic casing.

Bottomhole-assembly components that support directional control, including non-magnetic drill collars, stabilizers, bent subs, float subs, and orienting equipment used to build, hold, or drop angle.

Field services that plan and execute the well path, including directional drillers, MWD/LWD field engineering, geosteering, and survey management, delivered on a service or rental basis at the rig.
