Abstract: A marine vibrator has a housing that comprises a displacement member, the displacement member having a first position and a second position, the housing and the displacement member together defining an internal volume. A linear electromagnetic motor interacts with the displacement member so as to move the displacement member between a first position and a second position and correspondingly strokes the displacement member to cover a volume. The linear electromagnetic motor comprises magnets and coils that when energized create an electromagnetic force there between, wherein the linear electromagnetic motor comprises a piston and a guide that substantially surrounds the piston. The piston has incorporated therein either the coils or the magnets, and the guide having incorporated therein the other of the coils or the magnets. The piston is in interaction with the displacement member.

Abstract: An embodiment of the disclosed invention includes a method for attenuating noise during acquisition of marine seismic date. The method includes placing a seismic streamer in a body of water. The seismic streamer includes a streamer body having a length and a channel, a seismic sensor disposed within the channel, and a gel disposed within the channel. The gel has a complex viscosity of at least 50 Pascals and includes a concentration of a polymer between the range of about 5% and about 25% by weight. The method also includes placing a source in the body of water. The seismic streamer and the source are towed through the body of water and the source is fired while being towed through the body of water. Data is collected from the seismic streamer as it is towed through the body of water.

Abstract: Described herein are implementations of various technologies for a method for seismic data processing. The method may receive seismic data for a region of interest. The seismic data may be acquired in a seismic survey. The method may determine sparse seismic data by selecting shot points in the acquired seismic data using statistical sampling. The method may determine simulated seismic data based on an earth model for the region of interest, a reflection model for the region of interest, and the selected shot points. The method may determine an objective function that represents a mismatch between the sparse seismic data and the simulated seismic data. The method may update the reflection model using the objective function.

Abstract: A method of determining a migration pathway of a subterranean fluid through a geological volume is provided. The starting object is located within the geological volume. The starting object defines an initial fluid boundary. Data points are distributed through the geological volume. The data points are associated with values of one or more geological attributes. The method includes the steps of: defining an expression which determines a change in position of the fluid boundary at the data points over an iteration based on the values of the one or more attributes; and applying the expression at the data points for successive iterations to evolve the fluid boundary over the successive iterations. The migration pathway of the subterranean fluid through the geological volume can then be determined from the evolution of the fluid boundary.

Abstract: Methods and apparatuses for domain decomposition in computer simulations using an m-dimensional space-partitioning tree. The domain decomposition may be used in load balancing. Each subdomain boundary is adjusted according to its assigned computer node capability such that its load matches its capability. The subdomain simulation load may be acquired from predictive estimates or from actual measurement during the simulation execution. The load balancing domain decomposition may be done before the simulation starts or during the simulation.

Abstract: Described herein are implementations of various technologies for a method. The method may receive seismic attributes regarding a region of interest in a subsurface of the earth. The method may receive electrical attributes regarding the region of interest. The method may receive a selection of a rock physics model for the region of interest. The method may calculate values of rock parameters for the selected rock physics model using a nonlinear relation that links cross-properties between the seismic attributes and the electrical attributes for the region of interest. The method may determine the presence of hydrocarbon deposits in the region of interest using the calculated values.
