ACE SC 1 | The New Seismic Interpretation: Integrating Relative Geologic Time, Structural Geology and 3-D Seismic for More Effective Stratigraphic Exploration and Development
American Association of Petroleum Geologists (AAPG)
Saturday, 6 June 2020, 8:00 a.m.–5:00 p.m. | Houston, Texas
Who Should Attend
Geoscientists and managers tasked with converting integrated well and seismic data sets into value-additive opportunities.
Objectives
To introduce modern integrated Relative Geologic Time (RGT) workflows to working geoscientists and their managers.
Course Content
About 60 years ago, American geologist Harry Wheeler introduced what is now known as the “Wheeler Diagram”, a powerful tool that provided fresh insights into how facies are distributed in both time and space. While his ideas provided much of the theoretical framework for the later revolution in Sequence Stratigraphy, the technology of the time did not allow for the full exploitation of his ideas.
That has now changed. Several European software companies have recently introduced the Fast Wheeler Transform (FWT), with stunning results. The new workflow begins with the assignment of all faults, chronostratigraphic surfaces, logs and paleontological data to a “Relative Geologic Time” or RGT model. The FWT is then used to transform all data to 3D “Wheeler Space” where new insights and processes are possible.
This new approach introduces new tools but also new requirements for geologists to master if they are to be successful. It is analogous to the way that geophysicists discovered how “bright spot” exploration can reduce risk and uncertainty in exploration, but only after their seismic data had been made “AVO Compliant”. In a similar manner, the new toolkit available to geologists requires that their interpretations become both “RGT Compliant” and also “Kinematically Compliant”. This is accomplished in a common-sense way through a workflow that first decouples and then recouples Stratigraphy from Structural geology. This “S&S” approach is a successor to the more familiar “G&G” one and is well suited to RGT based workflows.
Topics covered in this course include the role that synkinematic deposition plays in the masking of onlaps, offlaps, etc., and how FWT’s solve this interpretation challenge; how the FWT can be leveraged to break out sequence boundaries; the development and understanding of powerful new “filled accommodation space” attributes derived from RGT models; how logs and paleobathymetry are best integrated into RGT workflows; how to use both structural restoration and forward modelling to achieve kinematic compliance of the RGT model; the role of sequence-centric QI tools such as Spectral Decomposition and geobody construction; the conversion of RGT into geocellular models for engineering purposes, and special requirements for subsalt exploration.
