Fremgangsmåte for utvandringskorrigering og estimering av stakkingshastigheter for forskjövne, vertikalseismiske profildata

摘要

A moveout correction process and stacking velocity estimation process to permit stacking of vertical seismic profile (VSP) data is disclosed wherein the primary reflection time is determined by using the two-way travel time, the root mean square velocity of acoustic pulses in the formation and the first arrival time of direct path acoustic pulses.
