Question 7

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
  • gravitational field strength = 9.8 N/kg9.8\text{ N/kg}9.8 N/kg

Calculate the depth of the borehole. Give your answer to 3 significant figures.
