Schlumberger announces high-definition NMR logging-while-drilling service

Schlumberger Schlumberger has announced the introduction of the MagniSphere high-definition NMR logging-while-drilling service to deliver accurate, real-time producibility analysis for optimum well placement

Utilising the industry’s first simultaneous measurements of T1 and T2 distribution while drilling, the MagniSphere service delivers real-time petrophysical evaluation data. This data is integrated into an intelligent processing workflow that provides operators with reservoir data used to identify producible hydrocarbon and enable precision geosteering.

MagniSphere service provides operators with a full understanding of reservoir producibility while concurrently enabling enhanced drilling performance,” said Jesus Lamas, president of well construction at Schlumberger. “The service provides operators with automated, high-definition NMR data while drilling, which is used to maximise reservoir exposure and ultimately optimise production.”

MagniSphere service has undergone extensive field testing, including in the Black Sea region where it enabled an operator drilling an extended reach horizontal section to better characterise the reservoir porosity and permeability profile, improving well placement into a higher quality pay zone. In the Middle East, an operator used real-time NMR logging-while-drilling for several wells in complex carbonate and clastic reservoirs to effectively characterise porosity profiles, identify permeable layers, and detect the presence of heavy oil and tar.
