The company owns the time migration, depth migration and RTM , meanwhile the company has successfully completed many complex geology imaging project in china and overseas, win the good reputation.
The company has rich experience and advanced technology in high resolution data processing.Near surface 3D Q compensation：Q value is derived from the seismic dataset and the near surface model together，the compensation is more targeted and more statistical；Surface consistent deconvolution in shot and receiver domain：Better surface consistent soluti...
Reducing multiple contamination is one of the greatest challenges in seismic processing, and no single approach fits all scenarios. In practice, these methods may be combined and cascaded to obtain the optimum solution. Multiple attenuation methods are：Predictive deconvolution, Tau-p deconvolution, high resolution radon transform, and surface relat...
Many forms of seismic noise contaminate our seismic recordings, degrading image quality, the wide range of noise generators means that no single noise attenuation technique will work in all situations. Accord to noise characteristic, we adapt targeted processing technique to remove noise.1) Cross-spread 3D FKxKy filter to remove ground roll and low...
Tomography statics solution is a inversion technique by modeling near surface depth-velocity to calculate the statics, solve the short period and long period statics problem.

Based on AVO theory, zero-offset (or small offset) section can be approximated as function of acoustic wave impedance AI, which is related to density and P wave velocity. Elastic impedance is the promotion of acoustic wave impedance, and it is the function of P wave velocity, S wave velocity, density and angle of incidence. Elastic impedance can pr...
Stochastic inversion is a kind of stochastic simulation technology based on geostatistics, as well as geologic structural framework model, well logging and seismic data. Taking layer as unit, that performs stochastic simulation by using spatial distribution regularity and spatial correlation of reservoir/oil and gas accumulation parameters, to acqu...
