Summary
Methods of determining static corrections have evolved from the times when statics could be determined easily from production records. The widespread use of surface sources with large source and receiver arrays, and also of crooked line recording, have made these determinations less straightforward, often necessitating separate weathering surveys such as LVL or up- hole surveys. Another aspect is the development of high-resolution work, needing extremely accurate static corrections. An automated method for determining these is described.
The choice of a processing datum is important, both for high-resolution work and for cases where shallow events on a section are important.
However good the automatic residual static programs are, the best results are obtained when the original field statics are as accurate as possible. A recent factor in the use of automatic statics is the cross-dip introduced by crooked line recording.
A set of examples shows some of the problems encountered in the use of automatic statics, including low-frequency static variations.
