摘要： A well (10) for producing water is characterized in that it includes a network of widely spaced electrodes (8) electrically coupled with measurement means (3) or with electric current generation means (1). By utilizing a measurement result, the progression of a salt water front heading for the well (10) may be detected.

摘要： In accordance with an illustrative embodiment of the present invention, a well logging apparatus uses a narrow wall-engaging pad equipped with an array of long vertical electrodes. The width of the pad is between 2 and 4 inches, and the length-to-width ratio of the array is between 3 and 5. Circuits are connected to the electrodes for propagating a focused current primarily through the zone of the adjacent formation likely to be flushed by the borehole fluid. This current and the associated potential difference are measured to produce a signal representative of the resistivity of the flushed zone.
