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:
“And boys, be in nothing so moderate as in love of man, a clever
servant, insufferable master.
There is the trap that catches noblest spirits, that
caught—they say—God, when he walked on earth.”
—Robinson Jeffers (1887–1962)
“His style is eminently colloquial, and no wonder it is strange to meet with in a book. It is not literary or classical; it has not the music of poetry, nor the pomp of philosophy, but the rhythms and cadences of conversation endlessly repeated.”
—Henry David Thoreau (1817–1862)
