  • Petroleum Technology Digest: EM survey defines reservoir, prevents dry hole

    T. Donze

    A new electromagnetic (EM) survey technique developed by Montason Exploration, Inc., has been used to define areal extent of a Niobrara prospect in eastern Colorado’s Denver-Julesberg basin. The prospect, thought to have about three sq mi of structural closure, actually had only 400 acres of closure according to the EM survey. Considering remote pipeline access, the potential reserves were too small to warrant drilling. The EM survey and interpretation helped the operator avoid large land, exploration and development costs for the project.
