Patents by Inventor Margaret A. Lessenger

Margaret A. Lessenger has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method of predicting three-dimensional stratigraphy using inverse optimization techniques
    Patent number: 6754588
    Abstract: The invention relates generally to the field of quantitative sedimentologic and stratigraphic prediction. Specifically, geological data observed or inferred from core samples, cuttings, geophysical well logs and seismic data from locations within a sedimentary basin, in conjunction with a stratigraphic forward model and an inverse optimization technique, are used to predict sedimentologic and stratigraphic attributes at locations within the basin other than those at which data were collected. The model's output consists of a three-dimensional model of the sedimentologic and stratigraphic attributes for the specified basin volume.
    Type: Grant

  • Method for predicting stratigraphy
    Patent number: 6246963
    Abstract: The present relates generally to the field of quantitative sedimentologic and stratigraphic prediction in which errors, uncertainties, risk and accuracy are calculated. Specifically, geologic data observed or inferred from core, outcrop, well log and/or seismic data from particular locations, in conjunction with a stratigraphic forward model and an optimization technique (mathematical inverse algorithm), are used to predict stratigraphic and sedimentologic attributes at locations other than those at which data were collected. This is accomplished by inverting a stratigraphic/sedimentologic forward model with simultaneous multi-parameter inversion or other mathematical optimization technique, such that forward model predictions are forced to obtain a best match with observations. The geologic data used to constrain the inversion are a small sample set of the larger, complete, rock volume simulated by the model.
