Overview

Extensional Setting Analysis of Structural Traps - ESS

About the Course

 The majority of continental and deepwater margins are fundamentally supported by extensional terranes, which are also home to some of the largest and most productive oil provinces in the world. They make up the majority of continental shelves and are one of the most prevalent structural types, being found on all continents. Structural mapping has undergone a revolution with the introduction of 3D seismic tools, but the most accurate geologic interpretation of these structures depends on our capacity to identify and take use of the basic properties of the forms that are feasible. This is the course's goal and objective.

 In order to enable structural interpretation in a variety of extensional contexts, including thin-skinned habitats, the underlying, frequently hyperextended passive margins, and intracontinental rifts, this course includes outcrop, subsurface, and seismic data as well as model analogs. Using predictive kinematics and restorative thinking, fault linkage, relay ramp, transfer systems, and intrabasinal structural geometries are examined in 3D. The significance of salt and strike-slip tectonics in the evolution of extensional basins is covered in the course, along with topics ranging from field level architecture to basin-scale design. With some discussion of the impact of deformation on reservoir quality, the common traps associated with extensional geometries are examined using examples from real-world situations. Exercises contain real-world field studies and common earthquake examples. Fundamentals of fracture dynamics are discussed in relation to the evolution of extensional faults, along with critical themes like inversion and fault sealing problems. The instructor is more than delighted to receive samples from your business for analysis during a demonstration activity in class. For a list of the documentation and support data needed, as well as the required lead time, please get in touch with PetroSkills. A 2-day field trip to the Death Valley region is taken after the 3-day in-person session to help students remember what they learned.

 Target Audience

 Geologists, geophysicists, engineers, and managers in charge of exploration and development who interpret and drill in extensional environments.

 Course Objectives

 Participants will pick up skills in:

•  Recognize the traits of extensional and trans-tensional deformation for thin-skinned and styles involving the basement.
• Utilize restoration/balance thinking and mechanical stratigraphic ideas when interpreting seismic and other data for extensional structures.
• Utilizing kinematic concepts, predict structural geometry from scant or inconsistent data.
• Analyze cross sections and interpretations for extensional structural settings critically.
• Create opportunities by capturing geometry in extensional structures.

Course Outlines

•  a variety of extensional structural styles, as well as information about where they arise and how they relate to other structural types.
• Fundamental mechanisms governing the development of extensional structures, include the transformation of a rift basin into a passive edge
• both 2D and 3D views of fault linkage, relay ramps, highs and lows in basins, and other extensional system components.
• relationships between complete and half grabens and the corresponding characteristics
• Relief in extensional systems and its connections to depositional, terrestrial, and marine systems, such as footwall uplifts
• Restoration and validation fundamentals; extensional system restoration methods
• ifts and fracture systems in extensional environments: fundamentals of fracture mechanics Examples and manifestations of these characteristics can be seen in southern Nevada and California's Death Valley Extensional Field.
