The NeoScope sourceless formation evaluation-while-drilling service reduces risk by eliminating the need for chemical sources in logging while drilling. As the industry’s only sourceless formation evaluation-while-drilling solution, the NeoScope service uses unique pulsed neutron generator technology in the shortest multifunction LWD service collar available.

Exploration drilling without chemical sources

In exploration drilling, the NeoScope service eliminates the need for chemical sources, avoids complex abandonment procedures, provides comprehensive petrophysical measurements in real time, and saves rig time through early evaluation to optimize drilling and logging programs.

Sourceless measurements in unconventional plays

In unconventional plays, the NeoScope service offers an extensive suite of sourceless measurements to evaluate reservoir quality, provides critical data to optimize completion quality, provides sourceless measurements in real time for better well placement, and removes transportation and handling risks and the costs of chemical sources.

Less rig time and risks in any drilling operation

In everyday logging, the NeoScope service saves rig time and mitigates risks by eliminating source loading and unloading, provides all measurements close to the bit, increases efficiency and safety by integrating all sensors in one collar, and avoids complex sidetracking and lengthy fishing operations.

Today, the NeoScope service is the only sourceless formation evaluation technology available that includes a dual azimuthal caliper, sigma, and spectroscopy.

Sourceless PNG-based spectroscopy, sigma, NG-density, and neutron-porosity measurements

In addition, the NeoScope service can distinguish formation fluids, determine the formation hydrogen index, and determine the sourceless neutron gamma density from gamma rays—enabling conventional formation evaluation without a nuclear source.
