Process, view and interpret CMR NG T1 T2 Maps
Process CMR NG T1-T2 data to compute a T1-T2 map at every depth. View the individual maps at depths selected interactively from a logview, or continuously "like a movie". Compute, view, and interpret a stacked T1-T2 map over an interval or a Rock Type. Compute fluid volumes and saturations from the maps.
Quality control of CMR+ signal phase and echoes
Two specific methods enable visualization of CMR+ echoes and signal phase for quality control.
Processing CMR+ Standard Station data
CMR+ standard stations are special acquisitions that enable robust T2 measurements by repeating and stacking data at a single depth. The standard station application provide workflow for processing and interpretation of high precision station data.
Time Domain analysis of porobodons with SPA
Zones containing specific isolated porobodons are identified from the CMR+ logs and borehole images. NMR Spectral Porosity Analysis is run over the selected zones with a wide parameter range to search for the defined porobodons. The statistical parameters of P10 & P90 distributions provide min & max settings for the entire interval of interest.
CMR NG T1 T2 Data Analytics
Interpret the T1 2 maps across the intervals or Rock Types for the underlying poro-fluid sources present in an Unconventional Shale well. Label the regions of the map with the fluids present - clay bound water, bound hydrocarbons, oil (gas) etc. and apply the analysis depth by depth. Sources from one well or from stacked data across multiple wells may be applied to other wells for consistency.
The NMR suite is a collection of applications for basic and advanced processing of logging data acquired using Schlumberger Wireline NMR tools - CMR+, CMR NG T1-T2 and MR Scanner. Applications provide workflows for data QC, inversion and final answers including porosity, permeability, fluid typing and oil viscosity.
CMR+ MRF Fluid Typing with DCLM Method
MRF station application provides the complete workflow for data QC, inversion and visualization of multi-dimensional NMR maps acquired using CMR+ stationary measurements. Estimation of fluid volumes from D-T2 or D-T1 maps is achieved using the diffusion coefficient logarithmic mean (DCLM) method.
Processing of MR Scanner Saturation Profiling Data
The MR Scanner application provides full set of functionalities for processing and interpretation of the Saturation Profiling depth log data. The application encompasses methods for quality control of echo data, inversion, 2D map visualization, and fluid typing.
Robust MR Scanner fluid profiling w/ stacked map method
Selection of optimal parameters for MR Scanner data processing and fluid typing is enabled with the stacked map method.
Stack CMR+ data for high precision answers
T2 stacking application allows CMR+ data to be zoned and stacked over a desired zone to obtain high-precision NMR answers. The stacked echo data can be processed to obtain the traditional NMR answers (porosity, permeability and pore/grain size distribution). The high precision answers are saved into a new dataset and can be displayed along with the depth log data.
