摘要： A method for determining spatial distribution of properties of the Earth's subsurface includes obtaining seismic data over a survey area of the Earth's subsurface. Controlled source electromagnetic survey data are obtained over substantially the same survey area. An initial model of the Earth's subsurface for each of the seismic data and the electromagnetic data is generated. Further data may include gravity, magnetics, seismics any type and borehole data. Each model is optimized on at least one model parameter. Consistency is determined between the models; and the at least one model parameter is adjusted and the optimizing and determining consistency are repeated until the models are consistent. Constraints are successively derived from the data sets and also cross checked against reservoir data where available.

摘要： There is provided herein a system and method of acquiring, processing, and imaging transient Controlled Source ElectroMagnetic (t-CSEM) data in ways that are similar to those used for seismic data. In particular, the instant invention exploits the time-distance characteristics of t-CSEM data to permit the design and execution of t-CSEM surveys for optimal subsequent processing and imaging. The instant invention illustrates how to correct t-CSEM data traces for attenuation and dispersion, so that their characteristics are more like those of seismic data and can be processed using algorithms familiar to the seismic processor. The resulting t-CSEM images, particularly if combined with corresponding seismic images, may be used to infer the location of hydrocarbon reservoirs.

摘要： A method for identifying features in the Earth's subsurface below a body of water using transient controlled source electromagnetic measurements includes acquiring a plurality of transient controlled source electromagnetic measurements. Each measurement represents a different value of an acquisition parameter. Each measurement is indexed with respect to a time at which an electric measuring current source is switched. The plurality of measurements is processed in a seismic trace display format, in which each trace corresponds to the measurement acquired for a value of the acquisition parameter. A subsurface feature is identified from the processed measurements.

摘要： The instant invention is generally directed toward methods of using an AVO-type analysis on unstacked seismic data to identify subsurface exploration prospects. More particularly, a new method of identiflying and displaying converted mode seismic reflections is provided that has significant advantages over that in the prior art. Additionally, the instant invention can be used to attenuate or eliminate seismic reflections such as multiples that are not flattened by conventional velocity analysis. Further, a method is disclosed that provides for identification and display of only those seismic reflections deemed consistent with the usual or expected AVO behavior. Finally, another aspect of the instant invention involves the use of statistical goodness of fit measures, such as the Coefficient of Determination, to create a seismic display that is indicative of the degree to which each time slice in a gather conforms to a proposed AVO model.

摘要： There is provided herein a system and method of collecting, EM data in the context(s) of hydrocarbon exploration, appraisal, development, and surveillance, which provides improved ground coupling between the electrodes and the earth or surface ice and, as a consequence, a higher quality transmitted and received signal is obtained thereby. Where the surface of the ground is saturated and frozen (e.g., in the case of a survey conducted on sea ice or frozen tundra), the survey instruments (sources and receivers) may be coupled more faithfully to the surface by drilling or melting holes into the ice (or frozen tundra) and inserting electrodes into the resulting holes. Each hole may (or may not) be lined with material to retard the loss of water therefrom. Preferably, each of the holes (source and receiver) will be filled with water (fresh or salt) before data collection begins.

摘要： The instant invention pertains generally to a method of seismic processing of multi-component converted wave 2-D and 3-D seismic data, wherein the seismic traces in each CCP gather may have been acquired at a variety of different source-receiver azimuths. According to one aspect of the instant invention there is provided a method of using recorded multi-component seismic data to determine an estimate of the orientation of the two principle coordinate axes of a subsurface medium, with this determination potentially being made in each seismic survey bin, and for each depth. Given this estimate, the seismic data may then be transformed via rotation into the coordinate system so defined, and thereafter processed using conventional algorithms (e.g., to produce velocity functions and images). Another embodiment of the instant invention uses a given principle coordinate axis orientation—which might have been obtained via the previous embodiment—to calculate a “best” data reduction of the traces in the CCP. In either case, the present invention additionally solves the problem of deducing the principal times series and provides a means of combining multi-azimuth multi-component CCP gathers for further conventional scalar processing. Those skilled in the art will appreciate that the methods disclosed below would be especially useful in 3-D surveys and in 2-D crooked line surveys.
