Abstract. The South Gabon Basin is a typical salt basin located in the middle portion of the West African passive continental margin, which has been found to be prospective in Pre-salt section especially after the discoveries of Diaman & Leopard in deep-water area.anticline or faulted anticline reservoirs are conducive to oil and gas accumulation and preservation. Mid-term faults and late faults are more likely to form traps, and these traps must require oil source faults in the downward-dipping direction to provide oil and gas in order to accumulate and become effective trap. ReferencesOct 23, 2018 · Abstract. K field is a faulted anticline structure lying in a turbidite environmental setting, which consists of two main sand bodies of 50-100ft gross thickness. Two main challenges during development stages were, 1). The narrow thickness of the fault block requiring accurate landing, well placement and characterization. 2). The low vertical permeability inside the sand which requires the ... review process can be seen on the example of small faulted anticline example (Figure 1 right). Current small subsurface closure is divided into smaller review areas based on surface facility constraint.

Backthrusts within the lower Cenozoic interval defines a triangle zone at the deformation front of the structure and prevents the propagation of deformation toward the north. Like an . anticline, the oldest rocks in a dome are found in the center. A basin is a depression, or dip, in Earth’s surface. Like a syncline, a basin has its youngest rocks in its center.Other types of folds include: monoclines. A monocline is a type of fold in which all rock layers incline, or dip, in the same direction.The broad, flat Central Kansas Uplift is a maze of small anticlinal and synclinal structures, many of which are faulted. Some, like the Fairport Anticline, trend northeast, and others, such as the Rush Rib, trend northwest.

In the northern parts of Mosul area, Jaddala Formation is replaced by Pilaspi and Gercus Formations.Fault 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. Structures from the Oriskany horizon to the basement were interpolated based on seismic and well data with a multisurface STACK procedure of the MCS package, and demonstrate a constrained half graben underneath the Warfield anticline with a 38th parallel and the north-south-trending Burning Springs lineaments.anticline meaning: 1. an upward, curved fold in the layers of rock in the earth's surface 2. an upward, curved fold in…. Learn more. The axial plane is an imaginary surface that contains the fold axis and generally splits the fold into symmetrical halves.

Other plays are emerging as exploration moves towards the hinterland. The Emerald Mountain discovery (132 MMBO of proven reserves) involves fractured Upper Cretaceous limestones as reservoir, which apparently seal against a thrust fault.An upward fold is called an anticline, while a downward fold is called a syncline. In many areas it’s common to find a series of anticlines and synclines (as in Figure 12.5), although some sequences of rocks are folded into a single anticline or syncline.
