Potassium lignite is the humic acid of leonardite treated with potassium hydroxide and used for use in potassium systems to control rheology, reduce fluid loss, and provide potassium for shale inhibition.
It is a specially formulated modified lignite compound compatible with all water base mud systems but it is developed specially for use in potassium based mud systems.Primarily it finds application in Potassium based inhibitive mud system as filtration control agent (Both at API and HPHT stipulated conditions) and as deflocculant. It is also used in fresh water, brackish, sea and salt water mud systems for the same purposes. It maintains stability at temperature above 200?C and is excellent emulsifier of oil in water emulsion fluids even at high bottom hole temperature in deep wells. It is also facilities effective shale stabilization in the water system when used in high concentration.Primarily it finds application in Potassium based inhibitive mud system as filtration control agent (Both at API and HPHT stipulated conditions) and as deflocculant.
