| 20090116337 | METHOD AND APPARATUS FOR MINIMIZING INTERFERENCE BETWEEN SEISMIC SYSTEMS - A method and apparatus for minimizing interference between seismic systems. The method may generally include: (a) actuating a plurality of first sources associated with a first seismic system to generate a first plurality of phase-encoded vibratory signals; (b) actuating a plurality of second sources associated with a second seismic system to generate a second plurality of phase-encoded vibratory signals that are at least partially frequency separated from the first plurality of phase-encoded vibratory signals generated in (a); and (c) detecting the first and second plurality of phase-encoded vibratory signals utilizing a first receiver positioned at a location remote from the first and second sources. | 05-07-2009 |

| 20100103772 | Marine Seismic Acquisition - A method of conducting multiple source, multiple signal seismic surveys in a marine environment are provided. | 04-29-2010 |
| 20100103773 | Simultaneous Multiple Source Extended Inversion - Methods for improving the range and resolution of simultaneous multiple vibratory source seismic system including ZENSEIS™ are provided. | 04-29-2010 |
| 20100118650 | 4D SEISMIC SIGNAL ANALYSIS - Methods of seismic data collection are described that reduce the amount of data required, reduce noise in the data collected and collect more data in areas where data collection is required. This results in a dramatic reduction of datasets required and improves noise reduction in data collected. By reducing the amount of data collected and increasing the noise reduction, a more accurate seismic survey is conducted at a dramatically reduced cost. | 05-13-2010 |
| 20100147512 | CONTROLLED SOURCE FRACTURE MONITORING - Reservoir fractures are visualized using electrically active proppants to carry electric signals throughout the fracture. The electric signals are easily detected at the surface using RF antennae and a three-dimensional image of the fracture is generated. | 06-17-2010 |
| 20100195434 | Heterodyned Seismic Source - The invention relates to an apparatus for generating heterodyned seismic signals as well as methods of using the heterodyned signals and a system for generating the heterodyned seismic signals. The heterodyned signals can be used near sensitive marine animals because the source frequencies are ultrasonic and the heterodyned seismic signal is generated in a narrow beam. | 08-05-2010 |
