HCOONa
Sodium Formate — Formate Brines
Organic salt used in formate brines and selected drilling / completion fluids where shale stability and high-density clear brines are required.
Application
High-performance brines for completion, workover and HPHT applications. Grade and purity must match the operational specification.
Technical characteristics (quality certificate)
Typical values as stated on a mill quality certificate (passport) for a standard commercial grade. Actual lot values are confirmed in the COA / TDS for the selected manufacturer.
Active content
≥ 98%
Manufacturer TDS
Achievable brine density
Up to ~ 1.42 sg (saturated Na-formate)
Completion brine practice
