Micro-C/Walnut Flour

Other Names: Ground Walnut Shells, Fine LCM Additive
Basic Properties: Loss Circulation Material, Wellbore Sealing, Bridging Agent
Micro-C, also known as Walnut Flour, is a finely ground, natural lost circulation material (LCM) used in drilling fluids to seal micro-fractures, prevent fluid loss, and improve wellbore stability. It is particularly effective in depleted formations where traditional LCMs may not be sufficient.
As a bridging agent, Micro-C forms a tight seal within the formation, minimizing fluid invasion and reducing differential sticking. It is often used in water-based, oil-based, and synthetic mud systems due to its versatile compatibility.
Additionally, Micro-C is biodegradable and non-toxic, making it an environmentally friendly option for drilling fluid formulations.
pH: Micro-C is pH neutral, ensuring it does not interfere with the chemical balance of drilling fluids.
By using Micro-C/Walnut Flour in drilling operations, operators can reduce lost circulation, improve wellbore sealing, minimize formation damage, and enhance fluid stability, ensuring smoother and more efficient drilling.
