Methodology of VSP data processing
Vertical seismic profiling is a powerful and widely implemented method of seismic exploration. It suggests a lot of opportunities for detailed reservoir study including velocities and anisotropy estimation, direct impulse shape registration, timedepth correlation, multi-wave analysis and imaging. These advantages of the VSP method are well known but often they become severely spoiled as a result of inappropriate processing techniques. In this paper we establish a number of general principles of VSP data processing and particularly for accurate wave field decomposition that ensures the high quality and reliability of acquired results of processing and interpretation. Examples of real VSP data processing are also presented to illustrate the application of the proposed techniques.
VSP data processing based on 1D-3D model of medium.
The conceptual VSP-oriented 1D-3D model is presented as convenient base of VSP processing and interpretation. The results of processing confirm the efficiency of technology in various applications.
Fragment Rotational State Distributions From The Dissociation Of NeIBr: Experimental And Theoretical Results
The IBr fragment rotational state distributions that result when the NeIBr van der Waals molecule undergoes vibrational predissociation have been measured in a pump–probe laser‐induced fluorescence experiment. Independent of initial vibrational state and the number of quanta of vibrational energy lost from the I–Br coordinate, the rotational distributions extend over the full range of energetically accessible states. From the observation of energetic constraints on the rotational distribution, the dissociation energy (D0) is calculated to be 65.5±1.2 cm−1 for the A electronic state, v=16. For the X electronic state, v=0, D0=71.8±1.2 cm−1. Quantum mechanical bound state calculations carried out on a model A electronic state potential energy surface are in quantitative agreement with this result. The rotational distributions are broader than that predicted by either a Franck–Condon or classical impulsive model for the dissociation. The distributions are qualitatively in accord with classical trajectory calc...
