Claim:
1. A method, comprising: transmitting a first signal by a first transducer based on a first electrical current value; receiving the first signal transmitted into a reservoir from a production installation in a formation at a wellsite at a second transducer and a third transducer; measuring the first signal at the second transducer to determine a second electrical current value and at the third transducer to determine a third electrical current value; determining an apparent resistance of the reservoir based on the first signal by multiplying a difference between the second and third electrical current values by a mean of fourth and fifth electrical current values, the fourth electrical current value measured at the second transducer and the fifth electrical current value measured at the third transducer when a fourth transducer transmits a second signal into the reservoir; and determining a distance between a fluid extraction tool and a fluid distribution based on the apparent resistance.
