Publication number: 20120087208Abstract: A deployment and retrieval method for ocean bottom seismic receivers, the method employs a remotely operated vehicle (ROV) having a carrier attached thereto to carry a plurality of receivers. The receivers are individually placed on the ocean bottom floor by utilizing a conveyor to move the receivers along a linear path to remove the receivers from the carrier. In one embodiment, multiple linear conveyors may be operated independently to alter the relative positions of the receivers on the respective conveyors to adjust the weight distribution of the receivers within the carrier.Type: ApplicationFiled: November 7, 2011Publication date: April 12, 2012Applicant: Fairfield Industries IncorporatedInventors: James N.

Patent number: 7983847Abstract: The transmission method utilizes multiple seismic acquisition units within an array as intermediate short range radio receivers/transmitters to pass collected seismic data in relay fashion back to a control station. Any one seismic unit in the array is capable of transmitting radio signals to several other seismic units positioned within radio range of the transmitting unit, thus allowing the system to select an optimal transmission path. Utilizing an array of seismic units permits transmission routes back to a control station to be varied as needed. In transmissions from the most remote seismic unit to the control station, each unit within a string receives seismic data from other units and transmits the received seismic data along with the receiving unit's locally stored seismic data. Preferably, as a transmission is passed along a chain, it is bounced between seismic units so as to be relayed by each unit in the array.Type: GrantFiled: May 22, 2006Date of Patent: July 19, 2011Assignee: Fairfield Industries, IncorporatedInventors: Clifford H.

Publication number: 20110032798Abstract: A wireless seismic data acquisition unit with a wireless receiver providing access to a common remote time reference shared by a plurality of wireless seismic data acquisition units in a seismic system. The receiver is capable of replicating local version of remote time epoch to which a seismic sensor analog-to-digital converter is synchronized. The receiver is capable of replicating local version of remote common time reference for the purpose of time stamping local node events. The receiver is capable of being placed in a low power, non-operational state over periods of time during which the seismic data acquisition unit continues to record seismic data, thus conserving unit battery power. The system implements a method to correct the local time clock based on intermittent access to the common remote time reference. The method corrects the local time clock via a voltage controlled oscillator to account for environmentally induced timing errors.Type: ApplicationFiled: October 19, 2010Publication date: February 10, 2011Applicant: Fairfield Industries IncorporatedInventors: Clifford H.

Publication number: 20090290453Abstract: A self-contained, wireless seismic data acquisition unit having a cylindrically shaped case with smooth side walls along the length of the case. A retaining ring around the circumference is used to secure the cylindrical upper portion of the case to the cylindrical lower portion of the case. Interleaved fingers on the upper portion of the case and the lower portion of the case prevent the upper portion and the lower portion from rotating relative to one another. Ruggedized external electrical contacts are physically decoupled from rigid attachment to the internal electrical components of the unit utilizing electrical pins that “float” relative to the external case and the internal circuit board on which the pins are carried. The seismic sensors in the unit, such as geophones, and the antennae for the unit are located along the major axis of the cylindrically shaped case to improve fidelity and timing functions.Type: ApplicationFiled: May 22, 2008Publication date: November 26, 2009Inventors: Clifford H.
