OBC-HIWI HT is the high temperature system of OBC-HIWI system. It is composed of selected iron ore powder and manganese ore powder as weighting agent, selected silicon powder as strength stabilizer, fluid loss additive, high temperature retarder, stabilizer and anti-channeling agent as auxiliary additives. OBC-HIWI HT can be used in high temperature and high pressure well, deep well and ultra deep well cementing.
