ESP temperature rising.

Thanks for ur reply.

I will bring up some precisions, the water cut of the well has remained around 80%. And the viscosity stable too. Somenody told me the dohwnhole gauge could be erratic, but I do not agree as the BHT has changed from 58.4 to 59.1 degC. Do you have any clue?

Can you tell if the power supplied to the ESP motor has increased? If so, that will explain a rise in temperature. In such a case, a problem with the motor or pump or both is being developing. If the motor draws more power for the ESP to lift the same fluid at the same rate, then for sure the extra power is dissipated as heat. Do you have only one bottomhole temperature gauge? Is that at the discharge or the suction of the pump?

Please, I wish I had ur e-mail address in my mailing list. Thanks for ur unvaluable input.

The Intensity and Voltage have remained almost the same (same frequency).
I think the motor is dying. We do have only gauges below the pump intake and thus no discharge pressure is monitored.
