Abstract: Certain aspects involve evaluating modeling algorithms whose outputs can impact machine-implemented operating environments. For instance, a computing system generates, from a comparison of a set of estimated attribute values of an attribute to a set of validation attribute values of the attribute, a discretized evaluation dataset with data values in multiple categories. The computing system computes, for a modeling algorithm used to generate the estimated attribute values, an evaluation metric. The computing system provides a host computing system with access to the evaluation metric, one or more modeling outputs generated with the modeling algorithm, or both. Providing one or more of these outputs to the host computing system can facilitate modifying one or more machine-implemented operations.

Abstract: Systems, processes, and computer-readable media for determining lithology porosity of a formation rock from surface drilling parameters using a lithology porosity machine learning model without the use of wireline logging. Lithology porosity at different depths in existing may be determined from the wireline logs. The lithology porosity may be shaly sand, tight sand, porous gas, or porous wet. The lithology porosity machine-learning model may be trained and calibrated using the data from a structured data set having surface drilling parameters from the existing wells and lithology porosity classifications from the wells. The lithology porosity machine learning model may then be used to determine a lithology porosity classification for a new well without the use of wireline logging.

Abstract: Disclosed is a method for predicting the future magnetic alignment of a runway. Extrapolating from previous historical records, the future trajectory of the Earth's eccentric geomagnetic axial pole (“ED”) is predicted. With that predicted trajectory as the basis, the future azimuthal change between the location of the ED and the location of an airfield is calculated. At the location of the airfield, a future change in the declination between true north and geomagnetic north is then calculated based on the predicted azimuthal change. The predicted change in declination then becomes the predicted change in magnetic alignment of any runway at the airfield. By predicting future changes in the magnetic alignment of a runway, preparations for changing the name of the runway can be made.
