N288 Interpretation of Seismic Data in Structurally Complex Settings
N288 Interpretation of Seismic Data in Structurally Complex Settings
Buisness Impact: The course combines structural analysis with a practical application of a workstation-based workflow and a set of “best practices” that can be used to approach complex data sets.
Seismic interpretations are often carried out in areas with multiple episodes of structural deformation. This course develops skills in interpreting 2D and 3D seismic data sets that show examples of structural reactivation and superposition of different structural styles, directions and timing.
A five-day classroom course comprised mainly of paper- and PC-based interpretation exercises and supporting lectures. The course learnings will be platform independent, but examples will be worked using IHS Kingdom software. The approximate ratio of exercises to lectures is 70:30.
Participants will learn to:
Many exploration areas have experienced multiple periods and directions of deformation. The resulting fault and fold patterns are usually complex and often misinterpreted. 2D and 3D seismic data in complex areas present very different problems for the interpreter. 2D seismic data sets are less time consuming to interpret but usually there are not enough data to constrain the interpretation. Complexly deformed 3D datasets can present a different challenge, as the frequency and complexity of the faulting can be overwhelming. In both cases, experience in unraveling multiple deformations, evaluating confusing map patterns, best use of seismic attributes for structural interpretation, and guidelines for interpretation are essential.
This course will introduce the seismic interpreter to 2D and 3D seismic data sets that show examples of structural reactivation and superposition of different structural styles, directions and timing. It will review and discuss existing structural concepts of reactivation fault patterns produced by more than one episode of deformation.
Structural interpretation topics covered will include:
This course is designed for the experienced interpreter working with complex seismic data, but could be applicable for geoscientists with a minimum of four to five years experience interpreting seismic data and at least a college level course in structural geology.
This course is designed as a Skilled-Level follow-on to Basic-Level N090 (Seismic Structural Styles Workshop). A basic knowledge of seismic interpretation is assumed, as presented in N085 (Introduction to Seismic Interpretation).
Geoscientists taking this course may also wish to consider field courses on the Nautilus Structure and Tectonics portfolio such as Basic level N016/N116 (Structural Geology for Petroleum Exploration Nevada, USA and SW England, UK respectively) or Skilled level N053 Compressional Structural Styles: Models for Exploration and Production (Alberta, Canada).
