Borehole Gravity Measurements in the Salton Sea Scientific Drilling Program Well State 2-14

PDF Version Also Available for Download.

Description

Borehole gravity measurements over a depth range from 1737 to 1027 m, and the vertical gradient of gravity above ground were measured at the Salton Sea Scientific Drilling Program well State 2-14. Uncorrected borehole gravimetric densities match values from gamma-gamma logs, indicating that the high densities seen in State 2-14 in the depth range 0.5 to 3 km extend for a few kilometers from the well. The above-ground gradient was found to be 0.0040 mgal/m higher than expected; correcting for this value increases the gravimetric density in the borehole. Combining the borehole gravity and estimated vertical gravity gradients on the ... continued below

Description

Borehole gravity measurements over a depth range from 1737 to 1027 m, and the vertical gradient of gravity above ground were measured at the Salton Sea Scientific Drilling Program well State 2-14. Uncorrected borehole gravimetric densities match values from gamma-gamma logs, indicating that the high densities seen in State 2-14 in the depth range 0.5 to 3 km extend for a few kilometers from the well. The above-ground gradient was found to be 0.0040 mgal/m higher than expected; correcting for this value increases the gravimetric density in the borehole. Combining the borehole gravity and estimated vertical gravity gradients on the surface, they find that this densified zone coincides with much of a broad thermal anomaly that has been found to the northeast of the Salton Sea Geothermal Field.
