Lithostatic load
WebThese calculations show that in an effectively isolated system, pressures would become very high and could considerably exceed the rock load, so that fracturing must occur causing pressure b eed off and loss of gas. The lithostatic gradient (1.0 psi/ft or 22.6 kPa/m) is reached after only about 1.0% of the oil is cracked. WebLithostatic pressure is a consequence of overburden stress, whereas hydrostatic pressure is the component of reservoir pressure caused by pore fluid. Lithostatic pressure is a function of rock density and is generally between 22.7 and 25.0 KPa/m (1.0 and 1.1 psi/ft) in … The processes of the geologic environment in which the coal was formed … The overburden depth at the test site is about 600 ft. Fig. 9.24 shows the … Thus, the overburden pressure is equal to the grain-to-grain lithostatic pressure …
