Patent number: 9239374Abstract: A beamforming method according to the present invention is a method of processing echo signals of a target region which are obtained from a probe including a plurality of receiving elements arrayed on a predetermined line. The beamforming method includes the following steps (S1 to S3). At S1, seed beams are formed from echo signals received by at least two receiving elements from among the plurality of receiving elements. At S2, a main beam and sub beams are formed by synthesizing at least one of the seed beams. At S3, a narrow beam for the target region is formed by multiplying the sub beams by respective predetermined coefficients and subtracting the multiplied sub beams from the main beam. Here, an signal intensity for the target region regarding the main beam is higher than a signal intensity for the target region regarding each of the sub beams.Type: GrantFiled: November 9, 2011Date of Patent: January 19, 2016Assignee: KONICA MINOLTA, INC.Inventors: Mineo Tsushima, Yasuhito Watanabe, Takeo Kanamori

Patent number: 9207342Abstract: A method is described for determining a shear wave velocity of a transversely isotropic region of an earth formation traversed by a wellbore with a non-zero relative dip angle between a longitudinal axis of the wellbore and an axis of symmetry of the TI region. A sonic tool is used to measure shear velocities in the TI region with polarizations orthogonal to the longitudinal axis of the wellbore. One of the shear velocities is identified as a quasi-shear velocity. A shear wave velocity is calculated, as a function of the quasi-shear velocity, for propagation in a direction along the axis of symmetry of the TI region. Where the orientation of the sonic tool is not known and the measured shear velocities comprises a fast shear velocity and a slow shear velocity, the method comprises identifying either the fast or the slow shear velocity as a quasi-shear mode.Type: GrantFiled: March 9, 2012Date of Patent: December 8, 2015Assignee: Chevron U.S.A.

Patent number: 9188692Abstract: A method is proposed for acquiring seismic data relative to an area of the subsoil, wherein at least one seismic source is moved and seismic waves are emitted in successive shooting positions of the source so as to illuminate said area of the subsoil, and the signals resulting from this emissions are picked up using a set of cables having a substantially zero buoyancy and provided with receivers. The cables have a substantially zero speed or a speed substantially slower than the source in the terrestrial reference frame. And said successive shot positions are determined as a function of the position of the receivers relative to the terrestrial reference frame to optimize at least one quality criterion relating to the set of seismic signals acquired by the receivers in respect of said area. Such a method enables improved seismic data acquisition.Type: GrantFiled: April 24, 2013Date of Patent: November 17, 2015Assignee: KIETTAInventor: Luc Haumonte

Patent number: 9170343Abstract: The invention is an electric seismic vibrator source of the type used in seismic prospecting for hydrocarbons that creates a quasi-impulsive burst of seismic energy onto the ground and into the earth. The source uses an engine and generator combination to create electric power for all systems on the source such as driving a frame of linear electric motors that direct a rod or piston to contact the ground. All of the linear electric motors are driven against the ground in a high power pulse that delivers a band-limited spectrum of seismic energy over a very brief period of time that would like a “pop” and be measured in milliseconds. A quasi-impulsive seismic pulse would create a wave field that resembles the seismic data acquired using dynamite or other explosive seismic systems without the ultrahigh frequencies of a true explosive pulse. The quick burst or several quick bursts may further speed up the survey by minimizing the time that a vibe spends on a source point.Type: GrantFiled: April 30, 2013Date of Patent: October 27, 2015Assignee: ConocoPhillips CompanyInventors: Peter M.

Patent number: 9170345Abstract: The invention is a method for extrapolating missing near-offset seismic data (101) so that the data may be used, for example, in SRME or another multiple-reflection elimination method. The invention uses the reciprocity principle (102) to relate two seismic states (acoustic or elastic) that can occur in a time-invariant, bounded domain in space. One of these states represents the physical experiment for the acquisition of the actual seismic data where near-offset traces are missing, and the other state represents a synthetic experiment with no missing near offset traces, computer-generated on a much simpler earth model. The reciprocity relationship used to relate these two states is iteratively inverted for the missing near-offset traces (103), preferably using only part of the synthetic data (102) so as to reduce inversion artifacts. The reference model acts as a constraint on the near-offset extrapolation.Type: GrantFiled: June 26, 2012Date of Patent: October 27, 2015Assignee: ExxonMobil Upstream Research CompanyInventors: Mamadou S. Diallo, Warren S. Ross

Patent number: 9164189Abstract: A method for managing a multi-vessel seismic system including a first vessel, having a recording system and towing a streamer integrating seismic sensors, and a second vessel, including at least one seismic source performing shots. The second vessel sends to the first vessel a plurality of series of shot predictions. For each shot, the second vessels activates the seismic source according to the predictions and sends to the first vessel shot data relating to the shot. The first vessel activates the recording system. If the first vessel has not received the shot data relating to at least one performed shot, it sends a request to the second vessel and receives in response the missing shot data. For each performed shot and the related shot data, the system selects seismic data and combines the selected seismic data with the related shot data to obtain combined data allowing a seabed representation.Type: GrantFiled: April 25, 2013Date of Patent: October 20, 2015Assignee: SERCELInventor: Didier Renaud

Patent number: 9164187Abstract: The invention is an electric power accumulator used with an electric sweep type seismic vibrator source of the type used in seismic prospecting for hydrocarbons. The source uses an engine and generator combination to create electric power to drive a frame of linear electric motors that direct a rod or piston to contact the ground in a recurring fashion. The source may also be designed to use electric power to drive the source from location to location through a survey area. A large electric power accumulator is provided to store electric power when the generator is able to produce excess power and the accumulator may deliver power along with the generator to drive the rods and deliver acoustic energy. With a large electric power accumulator, such as a battery or capacitor, the engine and generator combination may be engineered to be somewhat smaller, less costly and more efficient than a system where the engine and generator were sized to provide the electric power at times of maximum electric draw.Type: GrantFiled: April 30, 2013Date of Patent: October 20, 2015Assignee: ConocoPhillips CompanyInventors: Peter M.
