VSP

The separation of the cross-well seismic wave field can be regarded as an extension of the VSP wave field separation.

VSP is a typical NP-hard problem and is difficult to be solved by using pure mathematical methods.

Compared with general seismic techniques, VSP can remove noise effect more effectively and improve vertical resolution.

Theories and method of fracture detection by down-going S-wave information from zero offset three-component VSP data were introduced.

3D VSP is becoming one of important techniques in oil-gas field exploration and development.

Three-component VSP data of P-wave source are applied to fracture detection.

Crosswell seismic manifests some unique characteristics compared with surface seismic and VSP.

Tests on synthetic zero-offset VSP data showed that the method is reliable.

The vehicle-scheduling problem with time window is also a NP-hard problem being more complicated than VSP.

VSP jogging tool adopts advanced fiber optics sensor to test the oil-gas reservoir.

The method is used for data process in Well Block Ken 71 of Shengli Oilfield for 3DVSP imaging and better effect is achieved.

In addition, good effect has achieved from the separation of up or down wave for the practical VSP data.

VSP? Virtual Switching Point?

VSP? Video Signal Processor?

According to the research result, the 3-D VSP geometry design scheme for one actual deviated well has been made.

Based on original data, a geologic model is constructed according to the geologic tasks of 3-D VSP survey for Lungu 38 well.

Open the. VSP file in the IDE to examine performance data.
