F-SealCleat Seal

Short Description:

One-way Pressure Sealant for Oilfield Drilling (F-Seal/Cleat Seal) is made from natural fiber,filling particles and additive which is a product in the form of grey yellow powder, When used in drilling, it can effectively block up leakage of every kind from the formation under the action of one-way pressure difference. It also can improve mud cake quality and reduce water loss. It has very good compatibility and not affect the mud property.
