10 Questions
What is the purpose of Bcp in the equation mentioned?
To keep the ∆t– relationship linear
For which type of rocks is Wyllie's equation reasonably valid?
Consolidated sandstones
According to Raymer et al. (1980), what relationship exists between velocity and porosity?
Velocity decreases with porosity increases
What does RHG stand for in the Raymer–Hunt–Gardner sonic porosity equation?
Raymer–Hunt–Gardner

How do three-dimensional (3D) seismic surveys assist in investigating petroleum reservoirs?
They help identify likely migration paths, infer trap formation timing and charge, and measure the geometry of closed structures.
What is the role of rock physics in analyzing petroleum reservoirs?
Rock physics helps in analyzing reservoir quality, source rock, seals, and the capacity to contain hydrocarbons.
How is porosity related to the supply of petroleum in rocks?
Porosity determines the supply of petroleum that can be contained in the rocks.
What does the Wyllie Time Average equation relate seismic velocity to?
The Wyllie Time Average equation relates seismic velocity to porosity.
Explore the concepts of petroleum reservoirs in geophysics methods, focusing on the elements and factors contributing to oil and gas accumulations. Learn about source rock, reservoir rock, migration pathways, seal rock, trap, and more.
