Once the background has been developed, use the edge of the palette knife, loaded with paint only near the edge to define the periphery of mountains against the sky.

Their task is to find the right conditions for an oil trap -- the right source rock, reservoir rock and entrapment. Many years ago, geologists interpreted surface features, surface rock and soil types, and perhaps some small core samples obtained by shallow drilling.
