    • This invention relates to operating a seismic vibrator to produce a uniform displacement sweep wherein the baseplate drive is connected to the baseplate and the baseplate is moved in an up and down or reciprocating pattern creating displacement of the earth. The reciprocating pattern and physical displacement of the baseplate and the ground in contact with the baseplate is maintained at a relatively constant distance over at least most of the frequencies that are delivered into the earth although a constant displacement of the baseplate at higher frequencies will require greater power. The high frequency energy is more significantly present in the data traces of the recorded return wavefield and shows that Q attenuation is not fully to blame for the relative absence of high frequency data but rather in failing to effectively deliver high frequency energy into the earth in the first place.
    • 本发明涉及操作地震振动器以产生均匀的位移扫描,其中基板驱动器连接到基板并且基板以上下或往复的方式移动,从而产生地球的位移。 基板和与基板接触的地面的往复式图案和物理位移在传送到地球中的至少大多数频率上保持相对恒定的距离,尽管基板在较高频率下的恒定位移将需要更大的 功率。 在记录的返回波场的数据轨迹中,高频能量更显着地存在,并且表明Q衰减对于相对不存在高频数据而言并不完全是怪的,而是不能在高频数据的有效地将高频能量输送到地球中 第一名。

    • A seismic vibrator for obtaining a true ground force includes a baseplate pad; a baseplate drive system, the drive system is connected to the baseplate pad and moves the baseplate pad up and down; a vibrator controller electronics, the electronics are connected to the drive system and causes the drive system to move the baseplate pad up and down; and a plurality of load cell sensors disposed between the baseplate pad and ground, the sensors measure the vibrator output force during a sweep. A true ground force sweep includes using the load cell sensors to measure an actual output force of a seismic vibrator and electronics to obtain an actual ground force data; using inversion to invert the actual ground force data and desired original pilot sweep to obtain a revised pilot sweep that produces a true ground force sweep; and entering the true ground force sweep into the electronics

    • The invention relates to continuously or near continuously acquiring seismic data where at least one pulse-type source is fired in a distinctive sequence to create a series of pulses and to create a continuous or near continuous rumble. In a preferred embodiment, a number of pulse type seismic sources are arranged in an array and are fired in a distinctive loop of composite pulses where the returning wavefield is source separable based on the distinctive composite pulses. Firing the pulse type sources creates an identifiable loop of identifiable composite pulses so that two or more marine seismic acquisition systems with pulse-type seismic sources can acquire seismic data concurrently, continuously or near continuously and the peak energy delivered into the water will be less, which will reduce the irritation of seismic data acquisition to marine life.
    • 本发明涉及持续或接近连续采集的地震数据,其中至少一个脉冲型源以特定的序列发射以产生一系列脉冲并产生连续或接近连续的隆起。 在优选实施例中,多个脉冲型地震源被布置成阵列,并且在复合脉冲的独特环路中发射,其中基于特征复合脉冲,返回波场是源可分离的。 发射脉冲型源产生可识别的可识别的复合脉冲循环,使得具有脉冲型地震源的两个或更多个海洋地震采集系统能够连续或连续地获取地震数据,并且输送到水中的峰值能量将较少, 这将减少对海洋生物的地震数据采集的刺激。

    • Methods and systems are provided for acquiring seismic data in a marine environment using survey paths following a series of linked curved paths so as to obtain multi-azimuthal data over a sub-surface target. Marine vessels towing multiple seismic streamers may be configured to travel substantially along a series of linked deviated paths or a series of linked curved paths. Sources may be excited to introduce acoustic wave energy in the marine environment and into the subsea region. The acoustic wave energy then reflects and refracts from the subsea region to form reflected and refracted wave energy, which is detected by seismic receivers spaced along the streamers. The detected seismic data is then interpreted to reveal seismic information representative of the surveyed subsea region. Other enhancements include configuring the streamers in a flared configuration, where the lateral spacing increases rearwardly over the length of the seismic streamers.
