Anticline structure.

The Sumatou anticline is a NE-trending thrust-related fold structure located in the southwestern Sichuan Basin, with a length of ~40 km and a width of ~10 km (Fig. 1).Due to the demands for oil and gas exploration, the Sumatou anticline has been thoroughly explored using high-resolution 3-D seismic reflection volume and drilling data, which allows us to study the 3 …

This dissected anticline has been interpreted in the structural depth maps of the top Bahariya Formation, and top D and A members of the Abu Roash Formation, respectively (Figs. 8 and 9). This interpretation is consistent with structures that can be related to wrench tectonics within which both extension and compressional regimes occur..

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.Mar 28, 2006 · GENERAL FEATURES.

Anticlines are arch-shaped folds in which rock layers are upwardly convex. The oldest rock layers form the core of the fold, and outward from the core progressively younger rocks occur. A syncline is the opposite type of fold ... This is especially true when the anticline is formed from sedimentary rock layers. Anticlines form a structural trap that can capture pockets of hydrocarbons in the bend of the arch. Impermeable rock beds, often …Petroleum trap. In petroleum geology, a trap is a geological structure affecting the reservoir rock and caprock of a petroleum system allowing the accumulation of hydrocarbons in a reservoir. Traps can be of two types: stratigraphic or structural. Structural traps are the most important type of trap as they represent the majority of the world's ... An anticline is a structural trap formed by the folding of rock strata into an arch-like shape.
