Sourceless Formation Evaluation While Drilling
Publication: Journal of Petroleum Technology
Publication Date: 09/01/2012

Schlumberger has developed a new logging-while-drilling (LWD) technology that provides a formation-density measurement without the need for a chemical nuclear source. The NeoScope formation- evaluation-while-drilling service uses pulsed-neutron-generator technology that eliminates the need for chemical sources. This unique technology provides real-time measurements close to the bit to guide interpretation and decision making in all drilling environments. The new sourceless neutron/gamma-density measurement enables comprehensive sourceless formation evaluation from a single 25-ft collar, which is the shortest multifunction LWD suite available.
