The present disclosure integrates several methodologies for the detection and location of leaks in pipelines that transport hydrocarbons in liquid or gaseous phase. Detection is achieved through the management and processing of the data obtained by various measuring devices installed at strategic points on the pipeline infrastructure, this system does not alter neither structure nor mechanics of pipe and in case of a leak or flow caused by unauthorized actions, sensor system collect information on the physical variables of the fluid. This system may be made up of acoustic monitoring techniques, detection of negative pressure waves, as well as methods of mass and energy balance, integrated by multiple sensors, which are managed and controlled by electronic systems that process the information to determine the point of occurrence of a leak in digital maps. The system operates autonomously through the integration of solar cells for power supply and has satellite communication systems between the inspection sites and a monitoring center. It also can be remotely linked with SCADA systems (Supervisory Control and Data Acquisition) in real time. Additionally, it also has the technological integration of a motion sensor and a video and/or infrared camera together with a satellite modem whereby it sends images and video to the monitoring center, at the time of an unauthorized intrusion occurred on the pipeline in the area protected by a remote pipeline monitoring terminal (RPMT).

The present invention offers some general specifications for the design, assembly, and adaptation of a rotating cylinder electrochemical cell into an autoclave, of a high temperature and pressure system for corrosion studies that simulate operating conditions in pipelines, as well as the operation and safety of an autoclave to evaluate the electrochemical process of metal surfaces exposed to aggressive aqueous solutions. The electrochemical cell consists of an array of three electrodes that include a rotating cylinder electrode designed to operate hermetically, a reference electrode and an auxiliary electrode. The rotating cylinder electrode is considered to be the working electrode, where the oxidation and electrochemical reduction processes are studied. However, the use of the method described in this work can be extended to other testing environments and materials by taking into account the physical and chemical properties of the fluids and materials to be used in order to avoid any risk for the operator.

The online measurement system of radioactive tracers in oil wells head, object of this invention, is characterized by the use of new technology to measure concentrations of tracer activity in real time, using a radiation detector NaI (TI), with features that make it possible to detect up to three different tracers and be able to operate in temperature conditions up to 150&#xb0; C., which allows to be immersed in a container with fluid coming from the flow stream, achieving with this to increase the sensitivity of the measurements. This system of measurement in the head of production wells will allow having much more data of the tracer activity, avoiding having to transport the operational staff to production wells to carry out sampling test, with all the advantages that this represents.
