Lithostatic load

WebThe lithostatic stress gradient is the variation of total vertical stress with vertical depth (usually referred as true depth in petroleum engineering). The following subsections … Websupport the overlying load. Overpressured formations are also known as formations with abnormally high pore pressure. The lithostatic (or overburden) pressure at a given depth is due to the combined weight of the overlying rock and uids. The fracture pressure is the pressure that causes the formation rock to crack.
