摘要:
AVO anomalies are classified in near-offset and far-offset seismic data volumes, by first calculating a plurality of initial AVO seismic attributes representative of the offset seismic data volumes. A probabilistic neural network is constructed from the calculated initial AVO seismic attributes. AVO anomaly classifications are calculated in a portion of the offset seismic data volumes. The preceding steps are repeated until the calculated AVO anomaly classifications in the portion of the offset seismic data volumes are satisfactory. AVO anomaly classifications are calculated throughout the offset seismic data volumes using the constructed probabilistic neural network.
摘要:
Near-offset and far-offset seismic data volumes are time-aligned by first selecting a plurality of time shifts. The near-offset and far-offset seismic data volumes are cross-correlated at the plurality of time shifts. An initial time-shift volume and a maximum correlation volume are created from the maximal cross-correlations at the plurality of time shifts. Areas of high time shift from the initial time-shift volume and areas of low cross-correlation from the maximum correlation volume are determined. The determined areas of high time shift and low cross-correlation are filtered from the initial time-shift volume, generating a filtered time-shift volume. The filtered time-shift volume is applied to the far-offset seismic volume to generate a time-aligned far-offset volume.
摘要:
A method of analyzing dip in a seismic data volume in which a horizontal gradient is calculated in a first direction in the seismic data volume. A vertical gradient is calculated at data locations in the seismic data volume corresponding to the locations at which the horizontal gradient was calculated. Dip is calculated in the first direction from the horizontal gradient in the first direction and the vertical gradient. Repetition of the process for the entire seismic data volume results in a dip volume.

A method of calculating reflection curvature in a seismic data volume wherein an apparent dip value is calculated in a first direction to generate a first apparent dip volume. A horizontal gradient is calculated in the first direction in the first apparent dip volume using a specified length scale to generate a first curvature volume. The process may be repeated one or more times, and the individual curvature volumes combined to generate a combined curvature volume for the seismic data volume.

There is described an integrated reconfigurable man-portable communication system, adapted particularly for use in military or law enforcement tactical situations, including a modular compact computer with mission oriented hardware and software which provides the focal point for integration of various peripheral systems. The reconfigurable man-portable system provides a ballistic helmet with an integrated audio headset assembly. The helmet also includes a modular heads-up display assembly for providing remote viewing via a helmet mounted laser detection system, weapon mounted thermal weapons site, remote video system, and laser range finder/digital compass assembly. The heads-up display assembly and the audio headset assembly provides the user with tactical information such as; 360 degree laser detection from helmet mounted detectors, target location for direct and indirect target engagement from the weapon mounted laser range finder/digital compass assembly, and navigational positioning from a global positioning system and individual radio module integrated within a modular load carrying device. The integration and modularity of the man-portable system provides a flexible, mission oriented system capable of providing the user with enhanced awareness and communications ability.
