Abstract:
Seismic data and well logs are the primary tools for evaluating subsurface stratigraphy and dep ositional systems. The application of seismic stratigraphy and seismic fac ies analysis became the &ldquo\;go to&rdquo\; techniques for such interpre tations as a result of the publication of AAPG Memoir 26 in 1977 and the i ntroduction of the famed Vail/Exxon model for sequence stratigraphy. There have been a host of additional Publications that address the various appl ications of seismic and sequence stratigraphy since. The application of lo g shape otherwise known as log motif has been formalized to a much lesser degree. Observations regarding log motif as applied to interpretation of d epositional facies are commonly included in a supplementary way within pub lications focused on greater over all topics. One such publication is the text book Terrigenous Clastic Depositional Systems (Galloway and Hobday, 1 996).
This course is designed to familiarize the participants with the application of log motif and cycle stacking patterns to the interpreta tion of stratigraphic basin fill architecture and clastic depositional sys tems. A systematic evolution in log motif, both vertically (100&rsquo\;s t o 1000&rsquo\;s ft) and laterally (1&rsquo\;s km to 100&rsquo\;s km) can b e observed at the basin scale. In addition, there are a number of generic log shapes including funnel, bell, blocky, barrel, and serrate that common ly indicate specific depositional conditions such as confined or unconfine d depositional settings. These may reflect depositional patterns such as u pward coarsening, upward fining, channelized, and/or unconfined sheets. Ha ving said this, log motif is a very non-unique response. There are many cl astic depositional settings that may yield a similar log shape. For exampl e, a funnel shape log motif is common in progradational deltaic settings, basinward accreting shore zone systems and deepwater lateral and frontal s play complexes. Many workers avoid the application of log motif for this r eason. This course is based on more than 35 years of industry experience i n subsurface stratigraphic interpretation and the observation that the gen eric log motifs mentioned above occur in repetitive and systematic ways su ch that they can be effectively applied within the proper context. Integra tion of log shape and log attribute cut-offs can greatly enhance the effec tiveness of interval thickness and Net:Gross interpretations. The goal is to give the participants a sound understanding of log motif analysis with emphasis on prediction of reservoir body geometry and degree of stratigrap hic compartmentalization.
