SPWLA Saudi Arabia Chapter conducted its monthly luncheon technical event on 24 September 2017 by Holder Thern, Technical Lead for NMR Technology Center, BHGE. The theme of the event was on “Joint Interpretation of magnetic Resonance and Resistivity-Based Fluid Volumetric: a Framework for Petrophysical Evaluation’’ where the speaker presented a systematic compilation and discussion of main properties affecting resistivity and NMR fluid volume estimations such as Archie parameters and T2 cutoffs. Several log examples illustrate a wide range of reservoir scenarios. and also discussed the results to their applications ranging from real-time drilling optimization through hydrocarbon-in-place estimates and reservoir modeling input to production and completion decisions. The event was interactive and considered very educational with 56 participants from different companies.
