20130346354 | FORWARD INFERENCING OF FACTS IN PARALLEL - A method and system for inferring facts in parallel in a multiprocessor computing environment is provided. An inference system infers facts by applying rules to a collection of existing facts. For each existing fact, the inference system schedules a thread to apply the rules to that existing fact. As a thread infers a new fact (i.e., one that is not already in the collection of facts), the thread adds that inferred fact to the collection of facts. When a thread adds a new fact to the collection, the thread also applies the rules to that new fact. After the threads complete execution, the inference system may apply the rules to the facts of the collection, including the newly inferred facts, by again launching a thread for each fact to apply the rules to that fact. The inference system performs this processing iteratively until a termination condition is satisfied. | 12-26-2013 |
20130346445 | AUGMENTING QUERIES WHEN SEARCHING A SEMANTIC DATABASE - A method and system for identifying results of a query that includes a type predicate is provided. A search system maintains a collection of facts that includes a triple for each fact and a type table that maps entities of the facts to their corresponding type. The search system uses the type table to speed up the process of identifying the search results when the query includes a non-type query triple and a type query triple. A type query triple is a triple that has a type predicate, rather than a non-type predicate. To execute a query that contains a non-type query triple and a type query triple, the search system identifies the triples of the collection that match the non-type query triple. The search system then uses the type table to determine which of the identified triples match the type query triple for inclusion in the search results. | 12-26-2013 |

20100265797 | INTERFEROMETRIC SEISMIC DATA PROCESSING - Implementations of various technologies for a method for generating a seismic image of a subsurface are described herein. Seismic data may be received from two sensors in a seismic survey. The seismic data below and equal to a predetermined frequency may be classified as low-frequency seismic data. The low-frequency seismic data may be re-sampled based on the predetermined frequency. A set of low-frequency Green's functions may be calculated using interferometry on the re-sampled low-frequency seismic data. High-frequency seismic data of the seismic data may be processed to create a set of high-frequency Green's functions at one or more source locations of the seismic survey. The set of high-frequency Green's functions may be merged with the set of low-frequency Green's functions to create a set of broad-band Green's functions. The seismic image may be generated using the set of broad-band Green's functions at the source locations. | 10-21-2010 |
20110090760 | FULL-WAVEFORM INVERSION IN THE TRAVELTIME DOMAIN - A method for processing seismic data. The method includes predicting seismic data according to an earth model representing seismic properties of subterranean formations in the earth, determining a difference between seismic data acquired from one or more seismic receivers and the predicted seismic data, projecting the difference into a model space in traveltime, and updating the earth model according to the projected difference. As a result, the updated earth model more accurately represents the seismic properties of subterranean formations in the earth. | 04-21-2011 |
20120259601 | WAVEFORM INVERSION USING A RESPONSE OF FORWARD MODELING - Forward modeling is performed to compute a response of a target structure, the forward modeling accounting for distortion of a reflected signal from a reflector in the target structure. Waveform inversion is performed using the response of the forward modeling. | 10-11-2012 |

20090204331 | Method For Determining Geological Information Related To A Subsurface Volume Of Interest - A method of determining geological information related to a subsurface volume. In one embodiment, the method comprises obtaining a seismic information related to a subsurface volume; determining a horizon volume that automatically maps the seismic information into a flattened volume, wherein one axis of the flattened volume corresponds to chronostratigraphic time, and wherein horizons represented by the seismic information are automatically accounted for in the horizon volume, and are shifted by the horizon volume into the flattened volume to be substantially planar and substantially perpendicular to the axis of the flattened volume that corresponds to chronostratigraphic time; determining a derivative of the horizon volume with respect to chronostratigraphic time; and determining geological information related to the subsurface volume based on the derivative of the horizon volume with respect to chronostratigraphic time. | 08-13-2009 |
20090204332 | Method For Indexing A Subsurface Volume For The Purpose Of Inferring Geologic Information - A method of determining a horizon volume. In one embodiment, the horizon volume is determined from obtained seismic information, and maps the obtained seismic information onto a flattened volume such that in the flattened volume, horizons represented in the obtained seismic information are shifted to be substantially coplanar with a surface defined by the horizon volume as an estimate of a single chronostratigraphic time such that the parameters of the flattened volume include (i) a two-dimensional position in a surface plane, and (ii) a metric related to chronostratigraphic time. | 08-13-2009 |

The reverse time imaging includes modeling a pressure wavefield and a gradient wavefield in the region of interest based at least in part on particle motion data and pressure data acquired by sensors in response to energy being produced by at least one source. | 07-19-2012 |
20120215506 | WAVEFORM INVERSION BY MULTIPLE SHOT-ENCODING FOR NON-FIXED SPREAD GEOMETRIES - Seismic data processing methods and computing systems are presented. In one embodiment, a method is disclosed that includes simulating a set of simulated seismic data from a set of acquired seismic data; separating the simulated seismic data into a plurality of data sets, wherein one set of data is matched in the acquired seismic data and one set of data is unmatched in the acquired seismic data; conforming the simulated seismic data and the acquired seismic data to one another using separated, simulated seismic data unmatched by a counterpart in the acquired seismic data from the acquired seismic data; and performing an inversion between the acquired seismic data and the separated, simulated seismic data after they are conformed to one another. | 08-23-2012 |
20150046093 | INTERFEROMETRY-BASED DATA REDATUMING AND/OR DEPTH IMAGING - Processing measurements to create “reflectivity” data at a datum for a target using Joint Point-Spread Functions. The “reflectivity” data can be an image or an extended image. The methods can create single reflectivity data from measurements from multiple experiments, or multiple processed datasets via different processing routes from measurements from a single experiment, or measurements from a single experiment with multiple simultaneous sources. | 02-12-2015 |

20140182152 | Footgauge - A footgauge having a foot support plate having an upper surface on which the foot is placed with the heel against a fixed heel abutment. A touchscreen computer device (TCD) is inserted in a tray below the surface and engages a movable toe abutment. The toe abutment is moved into engagement with the foot and the user then and the user then presses a fixed pointer into contact with the screen of the TCD. The TCD is programmed and calibrated so as to give a foot length reading which is dependent on how far the toe abutment is moved towards the heel abutment. | 07-03-2014 |
