May 17, 2021 · Spectral gamma-ray (SGR) data were acquired from a new slim logging-while-drilling (LWD) tool and from surface cuttings in a near vertical well and in a horizontal well across clastic deposits. Comparison of the data from both measurements indicates that there are advantages from both methods.

OmniSphere SGR service uses spectral gamma ray (SGR) to provide real-time insight into the mineral composition of formations, enabling petrophysical decisions through clay typing and lithology in complex formations—particularly where sand-shale sequences are present.

EcoScope multifunction logging-while-drilling service integrates a full suite of formation evaluation, well placement, and drilling optimization measurements into a single collar that can be deployed faster than conventional LWD tools.

May 31, 2014 · Recently introduced azimuthal LWD measurements combined with well-site measurement of parameters on drill cuttings have proven to be a game changer in the quest for improved productivity in laterals drilled in shale reservoirs.

The Resistivity-at-the-Bit tool (LWD-RAB) makes azimuthal resistivity and gamma ray measurements while drilling. Using an azimuthal positioning system, measurements are acquired around the borehole to create a high resolution, 360-degree resistivity image of the drilled hole.

Jul 18, 2015 · A low-cost spectral gamma ray measurement has recently been developed for use in logging-whiledrilling (LWD) applications. Applications range from geosteering and bed boundary detection to formation evaluation for clay typing and for empirical correlations to estimate total organic carbon (TOC).
