Ikon Science wants to make every rock tell a better story
RokDoc made Ikon Science a specialist in reading the subsurface. With Curate and a widening software portfolio, it is taking on the work of making that knowledge usable across an energy business.
ResFrac Corporation
ResFrac Corporation builds the industry's only fully coupled hydraulic fracturing and reservoir simulator, letting energy engineers model the full life of a well - from the first crack in the rock to years of production - in one continuous physics-based simulation. Founded in 2015 by Stanford-trained engineer Mark McClure, the Palo Alto company is used by over 35 operators and 50 institutions worldwide across shale, conventional and enhanced geothermal plays.
