Publication number: 20110292758Abstract: A method of deploying a seismic recorder array on a seafloor is disclosed. The seismic recorder array comprises a plurality of removable seismic data recorders. The method comprises the step of forming the seismic recorder array by connecting a plurality of recorder housings in series, wherein adjacent recorder housings are connected by a connector cable. The recorder housings are configured to retain the removable seismic data recorders. The method comprises the step of loading the plurality of removable seismic data recorders in the recorder housings, and lowering the seismic recorder array into water until the seismic recorder array is positioned on the seafloor underlying the water. The method comprises the step of operating the seismic data recorders to detect seismic signal reflections and to record seismic data representing the reflections.Type: ApplicationFiled: May 27, 2010Publication date: December 1, 2011Applicant: GLOBAL GEOPHYSICAL SERVICES, INC.Inventors: Thomas J. Fleure, Craig Lindberg, Ralph B. Muse, Joe Davis, Damir S. Skerl, Justin N. Farrelly

Publication number: 20080049550Abstract: A method, apparatus and system for acquiring land seismic data includes acquiring seismic data with a first autonomous seismic data acquisition unit and a second autonomous seismic data acquisition unit wherein each acquisition unit comprises a plurality of digitally controlled temperature-compensated crystal oscillators. Oscillator-based timing signals are acquired that are associated with the plurality of digitally controlled temperature-compensated crystal oscillators and a time correction is determined to apply to the seismic data acquired with the first autonomous seismic data acquisition unit. The time correction is determined using the oscillator-based timing signals from the first and second autonomous seismic data acquisition units.Type: ApplicationFiled: August 22, 2006Publication date: February 28, 2008Applicant: Global Geophysical Services, IncorporatedInventors: Thomas J.
