| 20090015001 | COMBINATION POSTCARD AND CROSSWORD PUZZLE - A postcard combined with a puzzle to furnish the recipient with a diversion beyond merely reading the card. Preferred embodiments of the puzzle postcard, besides having the usual space for placing postage and a recipient's address and a space adorned with a symbolic representation and/or for writing a message to the recipient, also have at least one puzzle suited to be solved on a two-dimensional board. The contemplated puzzles may be not only ordinary crossword puzzles, but also Sudoku puzzles, code puzzles (relating numbers to words), and any other word- or number-related type puzzles suited to be solved on a two-dimensional board. | 01-15-2009 |

| 20110255370 | METHODS AND APPARATUS TO IMAGE SUBSURFACE FORMATION FEATURES - Methods of and apparatus to image one or more subsurface formation features are disclosed. An example method includes generating acoustic waves with a transmitter and receiving the acoustic waves and acoustic data contained therein at one or more receivers. The example method also includes extracting one or more S-S, P-S or S-P reflected waveform data from the acoustic data, estimating a dip of the one or more subsurface formation features, migrating the one or more S-S, P-S or S-P reflected waveform data with the estimated dip and mapping the migrated one or more S-S, P-S or S-P reflected waveform data. In addition, the example method includes identifying one or more permeable subsurface formation features using the mapped migrated one or more S-S, P-S or S-P reflected waveform data. | 10-20-2011 |

| 20090097356 | PROCESSING OF COMBINED SURFACE AND BOREHOLE SEISMIC DATA - Methods and related systems are described for processing surface seismic data. Surface seismic data representing seismic signals detected at a plurality of surface locations is wavefield deconvolved using a combination of direct wave travel times estimated from borehole seismic data, and wavefield energy estimated from the surface seismic data. | 04-16-2009 |
| 20090236145 | ANALYSIS REFRACTED ACOUSTIC WAVES MEASURED IN A BOREHOLE - Methods and related systems are described for measuring and analyzing refracted acoustic energy. A plurality of receivers mounted are on a downhole tool, and are arranged and adapted to receive refracted acoustic energy from a downhole formation. Measurements of refracted acoustic energy is analyzed such that information relating to an azimuthal direction relative to the downhole tool of an interface within the downhole formation can be estimated. The receivers can be mounted on a drill collar as part of a LWD tool and steering of the drilling trajectory can be based in part on the estimated formation information. | 09-24-2009 |
| 20090259404 | METHODS AND SYSTEMS FOR PROCESSING ACOUSTIC WAVEFORM DATA - Methods and systems for processing acoustic measurements related to subterranean formations. The methods and systems provide receiving acoustic waveforms with a plurality of receivers, deriving slowness of the formation based on the acoustic waveforms, and modeling dominant waveforms in the acoustic waveforms based on the formation slowness, wherein deriving the formation slowness comprises parametric inversion for complex and frequency dependent slowness and the derived complex slowness has real and imaginary parts. | 10-15-2009 |
| 20100103774 | VSP IMAGING OF ACOUSTIC INTERFACES - A method to generate images of acoustic contrasts for structures located between at least one acoustic source and at least one receiver, said structures converting a part of the compressional energy to shear. | 04-29-2010 |
| 20110051552 | METHODS AND APPARATUS TO CALCULATE A DISTANCE FROM A BOREHOLE TO A BOUNDARY OF AN ANISOTROPIC SUBTERRANEAN ROCK LAYER - Methods and apparatus to calculate a distance from a borehole to a boundary of an anisotropic subterranean rock layer are disclosed. A disclosed example method includes transmitting a first signal from a first transmitter at a first location in a borehole traversing a subterranean formation, receiving the first signal at a first receiver after a first time period at a second location in the borehole, receiving the first signal at a second receiver after a second time period at a third location in the borehole, and calculating a first distance from the first transmitter to a first portion of a boundary of a subterranean rock layer adjacent to the borehole by compensating for an anisotropy of the subterranean rock layer based on the first time period and the second time period. | 03-03-2011 |

| 20120008459 | SIMULTANEOUS OR NEAR-SIMULTANEOUS ACQUISITION FOR BOREHOLE SEISMIC - A technique facilitates performance of seismic profiling, such as three-dimensional vertical seismic profiling. A downhole acquisition system is provided with acoustic receivers designed to receive acoustic source signals. The firing of acoustic source signals is synchronized with the downhole acquisition system. Additionally, the firing of two or more acoustic source signals is controlled to provide simultaneous or nearly simultaneous timing of one acoustic source signal with respect to another acoustic source signal. A processing system is used to acquire and process a data stream of the initial shot and a data stream of the additional shot occurring simultaneously or nearly simultaneously. | 01-12-2012 |
