GENERAL GEOLOGY

Detailed explanation-1: -Anticline Trap An anticline is a structural trap formed by the folding of rock strata into an arch-like shape. The rock layers in an anticlinal trap were originally laid down horizontally and then earth movement caused it to fold into an arch-like shape called an anticline.

Detailed explanation-2: -Anticlines form a structural trap that can capture pockets of hydrocarbons in the bend of the arch. Impermeable rock beds, often referred to as seals or cap rock, trap hydrocarbons in the anticline peak. This causes oil and natural gas to build up in the pore spaces of the reservoir rock at the core of the arch.

Detailed explanation-3: -Structural traps are the most important type of trap as they represent the majority of the world’s discovered petroleum resources.

Detailed explanation-4: -Anticline Traps These types of traps are formed by a folding of rock. Specifically, a sandstone bed covered with low permeability shale is folded into a trap that contains petroleum products. Hydrocarbons are trapped in the peak of this fold.
