... is ensured by using an in-depth error analysis schema that includes various metrics like the correlation of determination, average error analysis, graphical error analysis, and scatter plots. This allows a relative ranking system to be generated that weighs various factors to classify one model as the most...

..., while ROP and borehole quality were improved. Through scrutiny of drilling dynamics, high frequency torsional resonance (HFTO) was revealed to be driving system mechanical inefficiencies. Log analysis enabled the correlation of the onset of HFTO to lithology type, and new drilling parameter limitations...

... Abstract The utility of advanced mud gas (AMG) data has been limited to fluid typing and petrophysical correlations. There is the need to extend the utility to real-time reservoir characterization prior to wireline logging and geological core description. Our first attempt to predict reservoir...

... Abstract Stratigraphic correlation in mudstone intervals is challenging as compared to coarser-grained sedimentary rocks because of the microscale heterogeneity and other constraints. Given critical mm- to cm-scale variability in mudstones, it is daunting to try to infer compositional...

Variations in the oriented LWD formation tester measurements at each depth station exhibited favorable correlations to azimuthal changes observed in the LWD high-resolution micro resistivity image. Detailed image analysis further helped...

To achieve a better prediction of diffusive mass transfer in ultra-tight fractured reservoirs, a representation that is based on a more fundamental...

.... In such system, as liquid droplet viscosity increases, upward drag force acting on droplet increases, resulting in lower droplet terminal velocity, thus larger annular flow region. To incorporate the effect of viscosity into Webber number, Hsiang and Faeth (1995 ) critical Webber number empirical correlation...

... for the next well, well-A. After good production results were achieved in well-A, the next phase used three more wells to correlate the production performance based on precise well placement. In well-A, openhole sampling was done during drilling of the pilot hole prior to sidetracking the lateral...

..., drilling induced fractures, and hydraulic fracturing success probability are all directly dependent on the reliability of the provided MEM. Considering that MEM have been historically developed based on empirical correlations and an expert manual interpretations of logging data, intuitively, their accuracy...

.... The correlation works well in the synthetic data. It has a potential to provide a new method for characterizing formation clays and water salinity from low frequency resistivity measurements such as induction logs that is routinely run in almost every well drilled. Thus, it provides a powerful economical tool...

... oil intervals. In all the wells analyzed, there was a good correlation among the calculated zone thickness, core data, sampling data, and mud logs. Dielectric logs were run in a couple of key wells, which enabled the S xo estimation independent of resistivity. Additionally, the S xo obtained...
