Product Description
Potassium Formate is chemically represented by the formula KCOOH. Potassium Formate is available as stock, clear fluid which can be used in workover and completion operations that require a density to 13.2ppg(1.58SG) and a base liquid for drill-in fluids. Formate-base brines are considered to have better HSE characteristics than chlorides and bromides brines for many applications. Although more expensive than alternative brines, potassium formate brines show excellent thermal stabilization effects on natural polymers and the potassium ions provides excellent clay stabilization and swelling inhibition of shales. Sodium formate is available as a dry-sacked material and as a stock liquid.
