“…Temperature gradients of about 20°-40°C/km exist in the Gulf Coast region in the upper 2 km. Geothermal gradients exceeding lOOoC/km are found within and immediately below the depth interval where maximum pressure gradient change occurred (Jones, 1970). The depth to the top of the geopressured zone conforms in a general way with a 120°C isotherm which occurs in the depth range of a 2.5 to 5 km below sea level (Jones, 1970).…”

“…Geothermal gradients exceeding lOOoC/km are found within and immediately below the depth interval where maximum pressure gradient change occurred (Jones, 1970). The depth to the top of the geopressured zone conforms in a general way with a 120°C isotherm which occurs in the depth range of a 2.5 to 5 km below sea level (Jones, 1970). The loss of load bearing strength due to thermal diagenesis which takes place between 80°C to 120°C is considered most responsible for creating the top of the geopressured zone.…”

“…It is believed that any or all of the following processes are responsible for the existence of a geopressured system: Rapid burial of saturated sediments, with rates of loading exceeding rates of water expulsion; development of osmotic pressure across clay beds; and liberation of water through diagenetic alteration of montmorillonite to illite between temperatures of 80°C to 120°C (Jones, 1969(Jones, , 1975. Such fields are found along the northern coast of Gulf of Mexico, and in many other parts of the world.…”

Single-phase and two-phase geothermal reservoirs are currently being exploited for power production in Italy, Mexico, New Zealand, the U.S. and Observations show that subsidence due to geothermal fluid production is characterized by such features as an offset of the subsidence bowl from the main area of production, time-lag between production and subsidence and nonlinear stress-strain relationships. Several plausible conceptual models, of varying degrees of sophistication, have been proposed to explain the observed features. At present, relatively more is known about the physical mechanisms that govern subsidence than the relevant thermal mechanisms. Although attempts have been made to simulate observed geothermal subsidence, the modeling efforts have been seriously limited by a lack of relevant field data needed to sufficiently characterize the complex field system.
