发明名称 Elongated particle breakers in low pH fracturing fluids
摘要 A method is given for the delayed breaking of a low pH fracturing fluid with acid-generating degradable elongated particles as a breaker for borate-crosslinked polymers. The shape, size, chemical composition and concentration of the elongated particles are used to control the period of delay before the polymer viscosity is broken.
