Trap Style
In geology, "trap" refers to the stratigraphic or tectonic structural feature that ensures the juxtaposition of reservoir and seal such that hydrocarbons remain trapped in the subsurface, rather than escaping (due to their natural buoyancy). Oil and gas trapped within the porous rock unit migrate to a high point in the structure because of their low density. In the Sirte Basin the dominant trap style is structural (84 percent), with the remainder considered stratigraphic or a combination of the two. As examples of combined traps, bioherm developments in the Paleocene Zelten Group are found on horst blocks, and clastic stratigraphic traps such as at Sarir or Messla field are superimposed on structures.

Famous quotes containing the words trap and/or style:
“The little lifting helplessness, the queer
Whimper-whine; whose unridiculous
Lost softness softly makes a trap for us.
And makes a curse.”
—Gwendolyn Brooks (b. 1917)
“A cultivated style would be like a mask. Everybody knows it’s a mask, and sooner or later you must show yourself—or at least, you show yourself as someone who could not afford to show himself, and so created something to hide behind.... You do not create a style. You work, and develop yourself; your style is an emanation from your own being.”
—Katherine Anne Porter (1890–1980)
