Title: Spectrum Extrapolation to Increase Resolution: ABSTRACT

Author(s): D. G. Stone

Article Type: Meeting abstract

Abstract:

Stratigraphic traps have been receiving increasing attention in the search for hydrocarbons. Greater resolution of detailed features are required for stratigraphic interpretation. Three weapons--continuous average Previous HitvelocityNext Hit, interval Previous HitvelocityNext Hit, and amplitude--have been widely studied. The extraction of higher frequencies has been less studied except in the framework of Wiener filtering. An alternate method is possible using Fourier theorems to extrapolate the spectrum to higher frequencies achieving greater pulse compression.

This new approach can increase the resolution of Previous HitvelocityTop analyses, migration, and automatic statics. Certain reflective sequences obscured by loss of higher frequencies such as pinch-outs, structural flanks, and closely spaced reflectors commonly are resolved by the method. Application examples show this as a possibly effective weapon in stratigraphic trap analysis.
