An automated sensor probe is lowered to the bottom of a deep geothermal exploration borehole filled with a dense synthetic drilling polymer to prevent well collapse.
the change in pressure recorded by the probe from the surface to the bottom was 104.5 MPa104.5\text{ MPa}104.5 MPa
mean density of the synthetic drilling polymer = 1380 kg/m31380\text{ kg/m}^31380 kg/m3
