Abstract[English]
Fluid is supplied fluid from a drilling string residing in a wellbore into an annulus between the drilling string and the wellbore based on a specified maximum temperature of the fluid in the annulus. The fluid in the annulus is cooled by the supplied fluid to at least the specified maximum temperature before the fluid exits the wellbore to the terranean surface.[French]
