Rook-

A dome is just an upside-down bowl. Oil percolates up through the water in loose rock formations until it is stopped by something that is impervious. If it can, it slides along this until it comes to the end, and then resumes it's upwards migration.

But every once in a while the impervious material is in the shape of a dome, and oil is trapped, and builds up until it fills the dome.

Thats what we are looking at with the 70' upwards hump in the Barnett Shale in this particular location.

I worked in the Norwegian and British sectors in the North Sea, where the domes were made of salt and were much bigger.
