Environmental problems associated with the production of energy from geopressured reservoirs

PDF Version Also Available for Download.

Description

A study of the environmental effects of power production from geopressured reservoirs reveals two important problems that cannot be adequately evaluated at this time: surfaces subsidence and the possible inducement of earthquakes, which could result from the efficient production of power over the lifetime of a reservoir. These effects must be considered in any environmental impact statement and must be monitored over the entire lifetime of a production facility. A particular reservoir in northwest Cameron County, Texas, was used as a model. Pertinent parameters are as follows: Depth of sand 14,300-15,000 ft; Thickness 700 ft; Temperature 320°F; Reservoir pressure (ave.) ... continued below

Environmental studies were based upon the properties and location of this model reservoir. (4 figs., 4 refs.)
