ABSTRACT:
A new class of viscosification agents based on water insoluble and oil insoluble neutralized sulfonated thermoplastic resins is described for oil-based drilling muds. The resultant muds display good viscosity characteristics and good stability when formulated from water insoluble and oil insoluble neutralized sulfonated thermoplastic polymers having an appropriate sulfonate level and cation type.
