Keywords: clay diapir, Shonghong basin, high pressure, Bao Wang, pliocene


Diapirs are very common in the center of the Shonghong Basin in the north of the continental shelf of the Socialist Republic of Vietnam. They are formed as a result of the release of high pressure in the Oligocene, Miocene layers. Exploration results show that gas discoveries in the Bao Wang field and adjacent fields are closely related to shale diapirs. This article is devoted to the results of diapirs interpretation, their activity based on the latest 2D, 3D seismic data from the Bao Wang field, blocks 111-113. The article also discusses and evaluates the origin, formation mechanism and role of diapir activity in relation to oil and gas accumulations.
