Systems and methods are disclosed. The method includes obtaining a seismic dataset for a subterranean region of interest and determining an inverted value of a stratum parameter by applying seismic inversion to the seismic dataset. The method further includes obtaining a well dataset within the subterranean region of interest and determining a standard deviation of the stratum parameter using the well dataset. The method still further includes iteratively or recursively defining a geological boundary condition for the subterranean region of interest, determining a stratigraphic model by applying forward stratigraphic modeling using the geological boundary condition, determining a measured value of the stratum parameter by applying a rock physics model to the stratigraphic model, and calculating the misfit value using the inverted value, the standard deviation, and the measured value until a misfit value is below a tolerance value. The stratigraphic model is then selected as a calibrated stratigraphic model.

Method of stratigraphic calibration

Methods and systems for identifying a multiple artifact are disclosed. The method includes obtaining a post-stacked seismic image of a subterranean region and identifying a horizon with the post-stacked seismic image. The method further includes determining a spectral section over the horizon by applying spectral decomposition to the post-stacked seismic image. The method still further includes detecting a frequency anomaly within the spectral section by comparing the spectral section to a reference spectral section and identifying the multiple artifact based on the frequency anomaly.

Event continuity mapping using seismic frequency analysis

A method, a system, and a non-transitory computer readable medium to calibrate a lithostatic stress map of a particular geological layer in a basin model are described. The lithostatic stress map is generated by simulating the basin model and calibrated based on available well data without re-simulating the basin model. In particular, the calibration is based on the mean lithostatic density, which is a constant value of density that yields a value of lithostatic stress equivalent to the lithostatic stress at the same depth produced by the existing column of rocks in the basin.

System and methods for heating boreholes include laser generators to trigger a chemical reaction to break down heavy hydrocarbons in boreholes. The systems and methods use arrays of laser generators at the borehole surface or within the borehole to heat the heavy hydrocarbons. The systems and methods may include hydrocarbon sensors within the borehole to detect gas seepage resulting from heating of the heavy hydrocarbons.
