Figure 16 gives a typical conceptual model and shows the difference about the development and distribution of a deep basin trap-controlled hydrocarbon reservoir in a petroliferous basin and conventional traps.

(2) Many types of petroliferous traps are developed in deep basins, and tight oil gas reservoirs in deep basin traps are arousing increasing attention.
Third, these reservoirs formed inside deep basin traps between the buoyancy accumulation threshold of a petroliferous basin and the basement of the basin.
Deep basin traps are a special type of hydrocarbon trap in which the reservoir media have porosities smaller than 12%%, permeabilities smaller than 1 × 10−3 μm2, and throat radii smaller than 2 μm.
In addition Lake Needwood was constructed to protect the water quality of the creek by functioning as a retention basin to trap all discharges from storm water runoff.
The material balance determines the distribution areas of deep basin gas traps, gas-bearing areas inside traps, and favorable exploration zone borders (Pang et al. 2003).
"Our acreage was in the center of the basin, no traps," Pat Medlock, a Brigham geologist, said.
A strip of that New-Guinea Basin was trapped along the complex transform boundary that separated the Indonesia Arc from the East Mindanao-Samar Arc (Fig. 5, Deschamps and Lallemand 2002).
When researchers added realistic topography to the model, including the 4-kilometer-deep Sputnik Planum and two other large craters, the basin gradually trapped Pluto's nitrogen, carbon monoxide, and much of its methane, the researchers report online today in Nature.
