What is Pinchout trap?
- 1. n.
- [Geology] A type of stratigraphic trap.
- The termination by thinning or tapering out (“pinching out”) of a reservoir against a nonporous sealing rock creates a favorable geometry to trap hydrocarbons, particularly if the adjacent sealing rock is a source rock such as a shale.
What is fault trap? A fault trap is a geological formation in which oil or gas in a porous section of rock is sealed off by a displaced, nonporous layer. A fault trap occurs when formations on either side of the fault move and lie in such a way that, when petroleum migrates into one of the formations, it becomes trapped there.
Accordingly What is an unconformity trap? Unconformity traps are those that resulted from the truncation of reservoir rocks and the subsequent sealing of the subcrop by an unconformable, relatively impermeable, fine-grained, rock unit. The source rocks may be within the pre-unconformity sequence, or in the immediate post-unconformity cap rocks.
Besides, What is combination trap? Secondary or even tertiary trapping elements commonly modify the primary trapping agent. Structural traps may have a stratigraphic component or vice versa. Sometimes the distinction whether the trap belongs to one system or another is quite blurred. Traps with two or more trapping elements are called combination traps.
What is a gas trap? Definition of gas trap 1 : a drain trap : sewer trap. 2 : an apparatus for separating natural gas from the petroleum in which it is dissolved.
What is trap theory?
A theory has been developed that relates many particularities of hydrogen embrittlement to the behavior of the trap population of the material during its exposure to hydrogen. In particular, it is shown that reversible traps may act as innocuous sinks or as detrimental hydrogen sources, depending on test conditions.
What is salt dome trap?
A salt dome trap is an area where oil has been trapped underground by salt pushing upward. A salt dome trap is where a mass of salt from deep in the Earth’s crust is pushed upward forming oil traps in a rock layer containing oil. Salt dome traps form where bodies of salt flow upward and pierce overlying rock layers.
What is meant by oil trap?
noun. 1A device in which oil can be trapped, or which makes use of oil to trap something else. 2Geology. An underground rock formation in which an accumulation of oil is trapped.
What is the most important part of a trap?
The most important element of your trap beat might just be your kick drum and 808 pattern. Your kick and 808 are what give your trap that heavy, trunk-rattling bass. Putting your kick or 808 on beat 1 is essential, but beyond that, you’re on your own.
What is gas trap?
Definition of gas trap 1 : a drain trap : sewer trap. 2 : an apparatus for separating natural gas from the petroleum in which it is dissolved.
What are the properties of a trap?
A trap consists of a geometric arrangement of permeable (reservoir) and less-permeable (seal) rocks which, when combined with the physical and chemical properties of subsurface fluids, can allow hydrocarbons to accumulate.
What is spill point?
1. n. [Geology] The structurally lowest point in a hydrocarbon trap that can retain hydrocarbons. Once a trap has been filled to its spill point, further storage or retention of hydrocarbons will not occur for lack of reservoir space within that trap.
