BioDrill TM100 deflocculation laboratory data

Deflocculation and thermal stability evaluation in KCl-polymer water-based drilling fluid

A KCl drilling fluid was prepared using pre-hydrated bentonite treated with KCl to produce a drilling fluid with the following characteristics: 9.3 ppg; 14 ppb KCl; 27 ppb API bentonite. The pH was adjusted to 10.5 and hot-rolled for 24 hours at 160°C.

Key takeaways:

  • BioDrill® TM100 reduces apparent viscosity and yield point even after ageing at 160°C.
  • Gelling is significantly reduced
