SIMULTANEOUS ESTIMATION OF PARAMETERS OF REFLECTION EVENTS (DEPTH, DIP, VELOCITY) AND RELATIVE STATIC CORRECTIONS*

It is pointed out that after identifying reflection events from the same horizon on two records obtained on the same spread from two different shotpoints, one can simultaneously estimate parameters of reflection events and relative static corrections. The parameters of reflection events are treated as quantities to compute whereas relative static corrections are treated as quantities to minimize by the least squares method. Static corrections obtained from different horizons for the same point on the spread are averaged.

The case of more than one pair of records for the same spread (or part of the spread), vital for multiple coverage, is also discussed.
