Intra-pore fluids
Natural gamma spectroscopy (NGS) and nuclear magnetic resonance (NMR) relaxometry
are bulk sensitive techniques that do not require time consuming sample preparation.
Adequate sample size and automation offer unique opportunity to use these techniques to
support drilling process based on drill cuttings measurements. Measurement targets for NGS
NMR combo on cuttings are mineralogy / lithology, total organic content (TOC) , concentration
of residual fluid.

NMR NODE
NMR node is designed to
provide reliable measurements
in presence of electromagnetic
noise and other attributes of
well-site environment. In order
to enable high throughput and
adequate data quality the NMR
data acquisition is accompanied
by automatically run frequency
tuning (to account for
temperature variation), adaptive
data stacking as well as gain
and background measurement.

Segments
• Tight silt mapping in vertical wells in Permian basin
• Pore pressure prediction application for deep offshore wells in
GoM
• Geo-steering of shallow wells (drill bit OD < 4” and / or use of coil
tubing )
• Geo-steering in complex carbonate reservoirs in Middle East
Value
• Cost savings: Lower cost alternatives to existing data acquisition
(e.g. LWD, WL)
• Value of information: Lower the “cost of entry” for obtaining
quantitative subsurface data that can reduce subsurface
uncertainty
