HRH Geology


David graduated in geology in 1975 and initially worked offshore as a geologist in the North Sea before moving into management with Gearhart Geodata Services.  Later, as General Manager, SE Asia, he opened and ran Gearhart’s first MWD base in the Far East.

David founded HRH Geology in 1989 to provide operational geology services to the oil industry.  After creating their Gravitas and Winlog software HRH also innovated with the Spectra mass spectrometry system, coupling it with HRH’s GeoPlacer wellsite geologists’ portal to provide a unique wellsite offering to the oil industry.  HRH is active in over 65 countries, deploying software, delivering training and placing geologists in a number of E&P environments.

In 2013 HRH Geology won The Queen’s Award for Enterprise in International Trade, followed by a second award in 2016 both in recognition of exceptional international growth.

David is now Executive Chairman of the company.
