摘要： A method of processing seismic data acquired consequent to actuation of a seismic source is described. The method comprises taking the result of the following process into account when processing the seismic data where the process comprises estimating the effect of uncertainty in the position and/or orientation of the seismic source relative to the measuring receiver on processing the seismic data by estimating a source wavefield from data acquired by a near-field measuring receiver and from a first parameter set including at least one parameter indicative of the position and/or orientation of the seismic source relative to the measuring receiver, varying the value of at least one parameter of the first parameter set, estimating the source wavefield from the data acquired by the measuring receiver and from the varied first parameter set and obtaining information about the uncertainty in the estimate of the source wavefield.

摘要： A method of monitoring a marine seismic source array comprises, consequent to actuation of a seismic source array (14), making a near-field measurement of seismic energy emitted by the seismic source array (14), using at least one near field sensor (15) and also acquiring seismic data using at least one seismic receiver (18). The far-field signature of the source array at one or more of the receiver location(s) is estimated from the near-field measurements of the emitted seismic energy, and this is compared with seismic data acquired at the receiver(s). This provides an indication of whether the source array and the method for predicting far-field signatures are operating correctly.

摘要： A technique facilitates the acquisition of seismic data at a substantially reduced source volume. The methodology generally comprises conducting a seismic survey with seismic sources that have a reduced source volume to collect seismic data. The low frequency data which is lost due to the reduced source volume is replaced with data acquired from a complementary method, such as a receiver-side acquisition method. The two sets of data are combined to provide a comprehensive seismic survey image without requiring conventional seismic source volume.

摘要： A device including a housing having an inside diameter defining a first chamber and a port formed through the housing in fluid communication with the first chamber. A shuttle flange, having a diameter, is moveably positioned within the first chamber. The shuttle flange moves during a gas-release cycle between i) a closed position blocking the port containing the compressed gas in the first chamber, and ii) an open position exposing an exit area of the port through which the compressed gas is discharged to produce a primary pressure pulse. Desirably, the primary pressure pulse produced has an average rising slope less than 2.9 bar-m/ms. A method for generating a seismic pressure pulse in water includes the steps of, confining a compressed gas within a chamber having a port, creating an exit area through the port by moving a shuttle along the length of the port during a gas-release cycle, pre-releasing a charge of the compressed gas through the exit area to create a pre-released bubble, choking the exit area, and producing a primary pressure pulse by releasing a main charge of compressed gas through the exit area. The primary pressure pulse may be created approximately at the maximum volume of the pre-released bubble. The primary pressure pulse may be created at approximately half of the bubble period of the pre-released gas bubble.
