Thank you for the incredible support of the GeoScience crew… Logan was courteous and helpful beyond all expectations. I cannot convey how grateful we were for his professionalism.

The model that they developed for us has been used since the late 90’s to manage the basin in an effective way. Without that I think we would really struggle to maintain production within this valley
