... interpreted mineral component volumes are consistent with core measurements. This manually intensive workflow is poorly defined, highly iterative, and generally limited in geologic scope and scale. The proposed solution to develop a more robust and predictive multi-mineral and fluid interpretation workflow...

... been a challenge for the oil and gas industry. In contrast to conventional techniques, the new method does not need water saturation obtained from core measurements for calibration efforts. All the parameters in the new workflow are geometry- or physics-based. We verified that formation-based geometric...

... to the well-log-based rock classification algorithm. Then the model parameters are updated in each rock-class and the multi-mineral analysis results are cross validated with core measurements in wells where core measurements are available. The iterative procedure is repeated until agreement with core data...

... iterations or agreement with core measurements (if available) is achieved. Finally, we perform an integrated completion-oriented rock classification to determine the best rock types for completion. We successfully applied the proposed workflow to more than 100 wells in 20 different counties in the Midland...

... control, and the Issler method because of the general paucity of good quality sonic log coverage in the Delaware Basin. Our project derived a petrophysical model to estimate TOC through the Bone Spring and Wolfcamp by calibrating ~1900 core measured TOC values from 57 wells to wireline curves...

Once blind testing has proven the model is satisfactory, gas and ash content together with the different facies can be predicted quantitatively from logs without cores. Rigorous...
