• Oil & Gas Industry Additives for Drilling and Fluid Loss

Sodium Gluconate

• Sodium Gluconate is an essential additive in oil well fluid loss and circulation applications because it can prevent scaling and precipitation, delay crosslinking reactions, and maintain fluid stability.

  Sodium Gluconate is a chelating agent commonly used as a scale inhibitor in oil well fluid loss and circulation applications. It is a polyol with multiple hydroxyl groups that can form bonds with mineral ions such as calcium, magnesium, iron, manganese, and copper. By binding to these ions, sodium gluconate can prevent them from forming scales or precipitates that can clog the well and impede fluid flow.

  In addition to its scale-inhibiting properties, Sodium Gluconate helps delay crosslinking of fluids containing titanate, zirconate, and borate ions. This is because it can complex these ions and prevent them from reacting with other components in the fluid until the desired time.

  Sodium Gluconate is also an excellent iron complexing agent, vital for maintaining enzyme breaker stability and crosslinked gel stability. Iron can catalyze the breakdown of enzyme breakers, which break down gels and promote fluid flow. Complexing it with a chelating agent like sodium gluconate is essential to prevent this reaction.
