Online measurement system of radioactive tracers on oil wells head

An online measuring system of radioactive tracers in an oil well head characterized by being able to autonomously operate and comprising:

• (I) a power supply plant for permanent energy supply which is constituted of a photovoltaic panel, a battery bank, a controller and a DC/AC current inverter (direct current/alternating current);
• (II) a gamma radiation detection module wherein the NaI scintillation crystal detector (TI) is housed in a stainless steel container of high pressure, through which will continuously flow the fluid samples coming from the well, whose concentration is required to quantify;
• (III) a programmable data logger by means of which all operation, control and data management functions are carried out in order to operate system autonomously according to the requirements of each test, constituting by the following stages:
• a) signal comparison and conditioning, b) pulses counting, c) control and storing and d) interface with the user (data input/output);
• and
• (IV) a laptop which has specialized tools as a computer program developed expressly for communication with the logger in order to carry out the following functions;
• a) programming of all logging functions, control and storing of data logger;
• b) data reading or collection of concentration vs time stored in the memory up to three channels;
• and
• c) data processing, presentation and management.
