摘要： Methods and apparatus are provided for generating velocity models for pre-stack depth migration ("PSDM"). Seismic, gravity and electromagnetic joint inversion input data are generated based on observed seismic, gravity and electromagnetic data (e.g., magnetotelluric and/or controlled source electromagnetic), and velocity, density and resistivity models. A joint inversion is performed to produce a multiparametric model that is a function of velocity, density and resistivity parameter distributions. The separate parameter distributions are extracted from the multiparametric model, and the extracted velocity model is used to perform a PSDM. A migration velocity analysis is performed on PSDM output to generate scismic image residuals. If the seismic image residuals meet predetermined quality objectives, the extracted velocity model is output as the final velocity model for PSDM. Otherwise, updated seismic, gravity and electromagnetic joint inversion input data are generated, and the process repeats in an iterative fashion until the seismic image residuals meet the predetermined quality objectives.

摘要： Measurement of petrophysical and geophysical data of formations in a wellbore using a long gauge bit having at least one sensor therewith. The at least one sensor may be installed in at least one flute of the long gauge bit and/or in the long gauge portion thereof. Data for creating images of the formations are obtained at or near the bottom of the borehole and proximate to the long gauge bit used for drilling the borehole. Orientation of the long gauge bit is also available on a real time basis. Magnetic and/or gravitational sensors may be used in determining bit orientation. The flutes of the long gauge bit and the long gauge portion thereof may have standard inserts to accommodate various types of different sensors and electronic packages therefor.

摘要： A method for modeling a subsurface anomalous density zone including the steps of forming a density model, computing a response to the density model, inverting the response to arrive at a geometric model of the anomalous density zone, and applying a sharpening function to boundary regions of the geometric model to distinguish between the anomalous density zone and a surrounding region.

摘要： A method for creating a heterogeneous earth model (HEM) of a reservoir field includes generating a group of wellsite models for a group of wellsites of the reservoir field based at least on cluster analysis and cluster tagging performed on log data of the group of wellsites, generating a reference model from the group of wellsite models, where cluster tagging errors of the group of wellsite models is minimized to obtain the reference model, constructing a contour plot of the cluster tagging errors on a cluster by cluster basis in the reservoir field, identifying at least one well location and associated core depth interval based on the contour plot for obtaining additional sampling results, and updating the reference model based on the additional sampling results to create the HEM.
