Zoom in on the smallest organic shale pores

Building on the capabilities of the industry-benchmark CMR-Plus combinable magnetic resonance tool, CMR-MagniPHI service pairs technological advancements with improvements in efficiency and reliability.

The new continuous T1 measurement made in combination with T2 relaxation at the industry’s shortest echo spacing of just 200 us captures high-definition NMR data from the smallest pores in organic shales to improve the identification of different fluid types.

Quantify certainty in any reservoir, any size pores

In addition to greater certainty in reserves calculations, new insight is brought to selecting the lateral drilling landing point and designing engineered completions and fracturing operations in shale reservoirs.
