CoreMix is a polysaccharide-based product containing inhibitive potassium ion and sized calcium carbonate for filtration control.
CoreMix is designed as a one-sack system for oilsand drilling and coring. CoreMix is formulated to enhance core recovery, minimize filtrate invasion, and reduce the sticking of bitumen onto tubulars. The use of bentonite and other additives is not required or recommended. In extreme situations where higher rheologies are required a xanthan such as Poly-Xan or Kelzan XCD may be used to increase yield points and gel strengths.
