Rosfloc KVP-S is an encapsulating polymer, used as an anti-decomposition additive for effecting on drill cuttings and bore hole walls. Rosfloc KVP-S forms gel-like structures in crevices which appear in hole walls during drilling, preventing penetration of water phase deep into the reservoir.
Application
The product is added directly into bentonitic dispersion or as a water solution. Dosing rate of Rosfloc KVP-S depends on drill fluid properties and ranges from 0.3 to 3.0 kg/m3. Application of Rosfloc KVP-S minimizes the problem of tight bore hole or washing-out of walls, prevents balling on stabilizer and bore bit.
