Logging While Drilling

Characterize the subsurface environment while drilling

Our logging-while-drilling (LWD) systems deliver high-quality reservoir-characterization data. Working in standard to extreme drilling environments, our technologies deliver real-time petrophysical, geosteering, imaging, geophysical, and geomechanical data that enhances reservoir understanding and enables on-the-fly drilling adjustments.

Gamma Logging

Measure naturally occurring radiation while drilling

With a full suite of gamma tools, we correlate your reservoir model, measure shale volumes, and deliver real-time well placement in any environment from routine to extreme.

Gamma Logging

Neutron Porosity and Density Logging

Measure neutron porosity and formation density while drilling

Our thermal-neutron porosity and azimuthally focused formation-density tools provide fluid typing, pore pressure evaluation, and petrophysical measurements that determine water saturation, lithology, and porosity.

Resistivity Logging

Detect boundaries and measure water saturation while drilling

Our resistivity suite provides measurements that help you to determine hydrocarbons in place, calculate water saturation, correlate against the reservoir model, and guide well placement with our deep reading capabilities.

Resistivity Logging

Sonic Logging

Acquire acoustic data while drilling

Our industry-leading sonic tools and experienced LWD engineers can help you to correlate seismic time-versus-depth measurements, determine porosity, and understand the mechanical state of the rock.

Borehole Imaging

Visualize the borehole environment while drilling

Regardless of mud type, our real-time imaging services identify structural and stratigraphic dip, locate natural and drilling-induced fractures, and characterize facies and stress orientation.
