Exploration Basis

EGS well analysis for fractures to determine the geologic framework of the east flank of the field

 

Notes

This paper summarizes petrologic and geologic investigations on two East Flank wells, 34A-9 and 34-9RD2 conducted as part of a continuing effort to better understand how the rocks will behave during hydraulic and thermal stimulation. Well 34A-9 is the hottest well at depth in the East Flank, reaching nearly 350 ⁰C. The reservoir on the East Flank is dominated by diorite and granodiorite.
