IMPROVING DRILLING EFFICIENCIES WITH POLYMER MUD

    Graphical Abstract
    • Abstract
  • Polymer based drilling fluids are used to drill 310 development wells in the Bashkortostan fields of Russian, with steady improvements in drilling efficiencies achieved.Their advantages, formulation, technology influences, lab tests and field applications are introduced. The average penetration rates increased by 25% over the wells drilled with clay based mud. Applications show that a combination of polymer muds and turbodrills in the reservoir intervals increases overall penetration rates over the rotary drilling mode. The total penetration time and costs on wellbore washing fell 15%~20% and 10% respectively, while formation damage is minimized.
