2D 3D Seismic Pre and Post Stack Modeling and Synthetics-Methods and Tools Course
Introduction:
This all-encompassing introductory course has been tailor-made to offer a robust comprehension of seismic acquisition, processing, and interpretation. Special attention is given to the aspect of seismic interpretation. Attendees will acquire a solid knowledge base, hands-on experience, techniques, and tools necessary for interpreting seismic data and assessing the accuracy of interpretations provided by external contractors. Numerous examples and practical exercises are incorporated to establish a connection between the course material and the exploration and development outcomes derived from seismic data.
Course Objectives:
Participants will learn the basic steps to acquire and process seismic, imaging differences between 2D and 3D seismic, and integrated seismic interpretation techniques. Additionally, students will study how to use seismic attributes and inversion data to predict reservoir characteristics, techniques to convert two-way time maps to depth, the use of Direct Hydrocarbon Indicators (DHI) to improve the chance of success for exploration and exploitation wells, and the use of seismic to predict geo pressure.
Who Should Attend?
Geologists, geophysicists, and engineers who want to use seismic data for petroleum exploration and/or production. Familiarity with geological terminology will be helpful.
