Mud cooler for HPHT wells
One of the modifications recommended is to install a mudcooler. This is basically a heat exchanger with interconnections for serial or parallel operation, depending on required mud temperature difference.
Seawater is used as cooling medium. The obtained temperature difference is 70 deg F with a maximum flow rate of 250 tons per hour.Although it is difficult to get a good feeling for the many temperature and time parameters, which determine the downhole temperature, the effect of such a heat exchanger could be quite significant. Lowering the maximum downhole temperature could reduce . . .
