| 主权项 | 1. A method of cleaning a wellbore drilled with an oil-based drilling fluid that forms an oil-based filter cake, the method comprising: emplacing a non-emulsified single phase breaker fluid into the wellbore, the breaker fluid comprising: at least 60% by volume of a water-miscible non-aqueous fluid forming a continuous phase;at least one weighting salt; andat least one breaking agent; and shutting in the well for a period of time sufficient to initiate breaking of the oil-based filter cake. | ||
