Abstract: Note on Previous HitFaultNext Hit Displacement

P. E. Narvarte

ABSTRACT

The accurate determination of Previous HitfaultNext Hit displacement is essential to accurate subsurface and seismic mapping.

When a Previous HitfaultNext Hit is cut by a well, the magnitude of Previous HitfaultNext Hit displacement is commonly obtained by direct comparison with an unfaulted nearby well. In areas of pronounced downdip thickening of section this technique, without proper adjustment, may lead to serious misconception.

A comparative graphic method is presented that gives a rational determination of Previous HitfaultNext Hit displacement and other Previous HitfaultNext Hit characteristics for conditions of pronounced downdip thickening of section and of faulting contemporaneous with deposition. Two actual costs of Previous HitfaultTop analysis in South Texas are discussed, one of which is compared to seismic data.
