ABSTRACT OF THE INVENTION An oil well instrumentation system for measuring the pressure and temperature at various depths during drill stem tests. The measurements may be hydrodynamically analyzed to map the geological structure of an oil field in order to sel- ect drilling locations. The measurements may also be utilized to calculate properties of an existing oil well such as total production and optimum production rate and to determine the geologic properties of the structure in which the well is drilled such as porocity. The system includes a pressure sensor, a temperature sensor and a microprocessor based device receiving the outputs of the press; e and temperature sensors for displaying ??d recording periodic measurements. The dis- play and recording device is powered by a rechargeable bat- tery, and the condition of the battery is internally monitored and an indication of its condition is displayed. Oil well measurements are relatively short in duration, but they are normally made over a relatively long period of time so that a substantial period of time elapses between measurements. In order to preserve the life of the battery between rechargings, the display and recording device is placed in a quiescent mode between measurements in which power is removed from most of the internal components including the microprocessor.
