Petrel Velocity Modeling

Level: Skill | Type: Classroom | Discipline: Petrel

The purpose of this course is to introduce the student to velocity modeling, velocity handling and domain conversion functionality in Petrel.

It takes the user through the preparation stage of data used for velocity estimation and modeling. This includes quality control and edit of checkshot data used in sonic calibration and quality control of time surfaces and well tops used for defining velocity intervals.

Furthermore, the available velocity modeling approaches are discussed, including well velocity estimation, the nature and modeling of seismic velocities, surface based and 3D grid based seismic velocity modeling, as well as user defined velocity functions.
After the velocity modeling phase, domain conversion of various objects and how to model structural uncertainty is covered.
