Extracting Key Exploration Information from Vintage Seismic

An Example from the NPRA, Alaska

There are many miles and square miles of vintage (ancient?) 2D and 3D seismic data in the world.  The availability of 1000s of miles of 2D data from the NPRA, Alaska, coupled with the significant discoveries by Armstrong and Conoco-Phillips prompted 3D Imaging Technology and Seismic Utensils to embark on a project to see if modern processing can be used to extract AVO information and other attributes to provide an inexpensive approach to reconnaissance exploration in the NPRA area.

The primary geological target is a series of prograding depositional packages in which the various components of these depositional bodies create potential stratigraphic traps. While the current discoveries are limited to shallower features it appears that other stratigraphic features at greater depths may be viable targets.  Seismic examples derived from 1970s & 80s 2D data show excellent results.   Careful reprocessing and the extraction of attributes including AVO have proven to be very useful tools in finding analogs to the major discoveries. This is in spite of the fact that the data is often only 3- to 6-fold at the shallow target.  The results show that careful processing by a highly experienced processor and analysis of the updated data can be a valuable early stage exploration tool.

However, these applied approaches to vintage data are applicable to other areas outside the NPRA where one does not have modern 3D or even 2D seismic.  These approaches are an inexpensive, yet valuable tool in guiding new exploration efforts.  Additional examples illustrate that AVO derived from pseudo-gathers can be included in neural network analysis to define interesting stratigraphic features in various geological locations, both onshore and offshore.

In summary, vintage (ancient?) data with updated processing and interpretation can be very useful in guiding reconnaissance exploration efforts.
