ABSTRACT:
An apparatus and related method for detecting oil and mineralized water, if it exists, in a well. The apparatus comprises a sensor assembly for placing down the well, the sensor assembly having a float therein that rises when fluid is detected and adapted to close an electrical contact of a circuit having a power source. The apparatus also has a base assembly used for raising and lowering the sensor assembly into and out of the well. An alarm is electrically coupled to the circuit that includes the sensor assembly and power source, the alarm operable to indicate when the electrical contact is closed.
