Lyons Sandstone, Denver Basin

Comments on Geologic Parameters

12b Formation Pressure:

Limited data indicate that the Lyons Sandstone reservoir has abnormally low pressures, at least locally in the Apishapa Uplift to the south. Pressures of less than 50 psi have been recorded at a depth of 1,100 ft. The subnormal fluid pressure in the Denver Basin has been explained as a consequence of the steady-state regional ground-water flow (Belitz and Bredehoeft, 1988).
