Abstract
A method of treating a subterranean formation penetrated by a wellbore is accomplished by introducing a fluid into the wellbore containing a combined fluid loss additive and breaker. The combined fluid loss additive and breaker is formed from particles of an organic peroxide provided on a substrate. The particles are sized to facilitate fluid loss control. A treatment operation is carried out wherein a treatment fluid viscosified with a polymer is introduced into the formation through the wellbore.
