Abstract
Results of NMR well logging and laboratory experiments were analyzed. The testing material comprised NMR data from the Upper Jurassic carbonates formation from a well located in the western part of the Carpathian Foredeep. Qualitative analysis of the T1 (longitudinal) and T2 (transverse) distributions from the NMR well logging was performed to illustrate differences in the plots regarding time position and amplitude of peaks in sandstones, carbonates and claystones. Quick identification of the reservoir zones in the borehole section was highlighted. Porosity values from NMR laboratory experiments, helium pycnometer measurements and NMR well logging were compared and the differences were explained emphasizing additional information derived from discrepancies. Permeability was calculated based on the NMR laboratory experiment results comprising free water, capillary-bound water and clay-bound water. NMR permeability calculations were compared with the results of Zawisza formula calculations and results presented by Halliburton Co. The permeability results were different, but the trend of the changes was similar. The analysis shows that NMR logging is very useful in the qualitative and quantitative interpretation of reservoirs despite the difference between the point laboratory results and continuous curves of logging outcomes. The final conclusion is as follows: to complete proper interpretation of very informative NMR laboratory and well logging data the full information about calibration of measurements should be available.
