20170285220 | STRESS TENSOR COMPUTATION USING MINDLIN FORMULATION - A method for performing an earth formation borehole-related task includes: calculating a contribution to stress at each grid cell volume of interest in a geo-cellular model from other grid cell volumes that are at elevations above the grid cell volume of interest by use of the Mindlin Formulation using difference values between actual and linear approximation density values and Poisson's ratio values; adding all contributions to the stresses from all other grid cell volumes that are at elevations above the grid cell volume of interest to provide a stress tensor correction; adding first approximation of stress tensor components to the stress tensor correction to provide a total stress value; constructing a resulting stress tensor for the earth formation using the total stress values for the grid cell volumes of interest; and performing the borehole-related task using borehole-related equipment and the resulting stress tensor for the earth formation. | 2017-10-05 |
20170285221 | GENERATING DYNAMICALLY CALIBRATED GEO-MODELS IN GREEN FIELDS - Techniques to generate dynamically calibrated geo-models green fields are described. A geo-model representing a field on which wells are drilled in a hydrocarbon-bearing formation adjusted to generate multiple adjusted geo-models. Each adjusted geo-model represents a variant of the numerical geo-model. Using each adjusted geo-model, multiple simulated rates of change of bottomhole pressures over time in a well drilled in the hydrocarbon-bearing formation are determined. A measured rate of change of bottomhole pressures over time in the well is compared with the multiple simulated rates of change of bottomhole pressures over time in the well. Based on a result of the comparing, the adjusted geo-model that yielded simulated rates of change of bottomhole pressures that best matched the measured rate of change of bottomhole pressure is identified. A geological property associated with the best-match adjusted geo-model is determined and presented in a geological property contour map of the hydrocarbon-bearing formation. | 2017-10-05 |
