The Rock Physicist leads a geosciences team whose responsibility is to derive and apply geomechanical and rock-property knowledge to better understand the physical parameters and stress environment of the subsurface. Projects may include using rock-property information to analyze and incorporate borehole information into various subsurface analyses, putting constraints on and providing uncertainties in velocity and property models used to image the subsurface, using seismic measurements to analyze and predict subsurface vector stress fields and pore-pressures, deriving rock lithologies through single and joint inversion of seismic and other geophysical data, developing and evaluating drilling and well casing plans, and using real-time well measurements to update subsurface geomechanical models and reduce drilling hazards ahead of the bit.
Successful Rock Physicists have the ability to balance technical purity against project deadlines and financial factors. They adapt easily and positively to respond to last-minute project changes.
- Construct 3D static and 4D dynamic geomechanical models on field to basin scales.
