Abstract: A method and system for providing centralized deployment and coordination of field assessment activities. In accordance with one embodiment, an emergency management data processing system includes a field assessment database for storing and processing layered geospatial visual portrayal data and field surveillance attribute data. The emergency management data processing system includes an event setup data input interface for receiving an event identifier associated with an emergency event, a location identifier identifying a portion of the layered geospatial visual portrayal data corresponding to a region affected by the emergency event, and a field surveillance attribute category identifier specifying a category of the stored field surveillance attribute data. The event identifier is then associated with the region data and the specified field surveillance attribute data to generate an event-specific field assessment record.

Abstract: A set of seismic trace data is collected in an input data set that is first Fourier transformed in its entirety into the frequency domain. A normalized wavefield is obtained for each trace of the input data set in the frequency domain. Normalization is done with respect to the frequency response of a reference trace selected from the set of seismic trace data. The normalized wavefield is source independent, complex, and dimensionless. The normalized wavefield is shown to be uniquely defined as the normalized impulse response, provided that a certain condition is met for the source. This property allows construction of the inversion algorithm disclosed herein, without any source or source coupling information. The algorithm minimizes the error between data normalized wavefield and the model normalized wavefield. The methodology is applicable to any 3-D seismic problem, and damping may be easily included in the process.

Abstract: Methods and systems are provided for acquiring seismic data. Data are collected representing acoustic signals received from the Earth at distinct geographic locations. Data representing an ambient signal at the distinct geographic locations are also collected. For each of the geographic locations, a known time dependence of the ambient signal is correlated with a time dependence of the collected acoustic-signal data to define time-correlated acoustic signal data. The collected acoustic-signal data for the distinct geographic locations are synchronized from the time-correlated acoustic-signal data.

Abstract: A method and system is disclosed for communicating information from a downhole location to the surface including a plurality of releasable vessels containing predetermined signal information affixed to the vessels prior to placement of the vessels downhole and indicative of the presence of at least one of three or more predetermined downhole conditions and a sensing and releasing system that senses the occurrence of the downhole condition, such as a simple threshold, and release the vessels in response to the sensing.

Abstract: The aim of the present invention is the determination of the best possible correlation (keying) for electric recordings obtained in a borehole with seismic recordings obtained in a volume of subsoil (the seismic block) containing the bore. This is accomplished by defining in a neighborhood of the trajectory of the bore a set of layered networks, the entries of which are the seismic signals and the exits of which are electric signals. Accordingly, a quality measure is awarded with regard to the convergence. The best convergence quality then permits the determination of the best place in the neighborhood which produces the best keying.

Abstract: A method of processing data of seismic traces for geophysical interpretation of the earth's subsurface includes the steps of determining a modified Hilbert transform of an input trace of data values to detect rapid and slow changes in the input trace with reduced sensitivity to noise and providing results of modified Hilbert transform to enable identification of any detected rapid or slow changes. The modified Hilbert transform is advantageously a windowed Fourier transform, wherein the input trace is represented as x(t), where t indicates time, a window function is represented by win(?), a first function is defined as g(?)=x(t??)·win(?), X(t,?) is the Fourier transform of g(?), hi(t) represents a sum over imaginary portions of X(t,?), hr(t) represents a sum over real portions of X(t,?), and the modified Hilbert transform is h(t)=hr(t)+i·hi(t). In its most general form, for any integer n greater than 1, hr(t)=??Real {X(t,?)}n and hi(t)=??Imag{X(t,?)}n.

Abstract: One or more high resolution logs of a formation property having thin beds is provided for the laminated formation. From this log, the bed boundaries are detected and the facies for each of the beds detected is identified, using one or more high resolution logs of the laminated formation. Each of the identified facies is then defined. One or more squared logs for formation property is then generated by using the imported volumetric descriptions of the facies to generate a value of the formation property for each of the beds. A reconstructed log is generated and compared with a low resolution log of the formation property for laminated formation. By adjusting the values of the squared log the difference between the reconstructed log and the squared log may be minimized. An optimized squared log is output as having the square log and the volumetric analyses thereon.

Abstract: A lightning detection system provides an estimated location of a lightning stroke. The system includes sensors and an analyzer. Each sensor within range of a lightning event provides messages to the analyzer. Each sensor includes a waveform engine that converts a signal received from the lightning event to a series of frequency domain components having respective magnitude and phase. The waveform engine adjusts magnitudes and phases of the frequency components, for example, to mitigate the effects of terrain conductivity where the received signal traveled across terrain. The adjusted frequency components are then converted by the waveform engine into a second time domain signal that is described in a message to the analyzer. Each message includes sensor identification, peak amplitude, and time of detecting the lightning event. The analyzer provides an estimated location of the lightning stroke and an estimated peak current of the lightning stroke in accordance with messages received from sensors.

Abstract: A modification to the Coates-Timur relationship to produce a more coherent relationship applicable to carbonate formations is disclosed. In this method, permeability may be determined using porosity and the ratio of bound fluid volume to (1—bound fluid volume). This method also allows for improved estimation of irreducible water saturation of a carbonate formation using the ratio of kc and (e?f+kc). Likewise, the bound fluid volume of a carbonate formation may be determined using the ratio of ?kc and (e?f+kc). In these relationships, e, x, and f are constants according to the following relationships e=xc, f=bc+1, x is between 1 and 100 mD (preferably 10 mD).
