Abstract: A method is disclosed for combining seismic data sets. This method has application in merging data sets of different vintages, merging data sets collected using different acquisition technologies, and merging data sets acquired using different types of sensors, for example merging hydrophone and geophone measurements in ocean bottom seismic data.

Abstract: The present invention is a method for predicting the grain size distribution at a designated location within a water-lain sedimentary deposit. Initially, the vertical thickness of the sedimentary deposit at the designated location must be determined, as well as the vertical thickness and grain size distribution at a second location different from the designated location. Second, a distance parameter corresponding to the two locations must be determined. Finally the distance parameter is used, along with the initially determined vertical thickness at both locations and the grain size distribution at the second location to calculate the grain size distribution at the designated location.

Abstract: The internal properties of a water-lain sediment body can be determined from the shape of the deposit. One method comprises solving equations relating the shape of a sediment body to the flow field that produced the body and using the flow field to solve for the sediment body properties in at least one point within the body. The flow field properties include flow velocity, suspended sediment volume fractions, deposition time, and flow height. The properties of the water-lain sediments include, in addition to the flow properties associated with deposition of the sediments, the thickness of the sediment body, the size of the body, the shape of the body, and the grain size distribution at points within the body.

Abstract: The properties of a water-lain sedimentary deposit may be predicted at any location from a contour of constant deposit thickness. One embodiment of the method comprises (a) determining an outline of constant deposit thickness in a measured deposit, (b) determining the fluid flow properties at the inlet of the measured deposit, (c) determining a property of the deposit at any point inside the deposit from modeling the fluid flow. The properties of the deposit at any point may include the thickness of the sediment body, the size of the body, the shape of the body, and the grain size distribution at each point within the body, and any combination thereof.
