Abstract: The present invention relates to alternative equipment for solar energy prospecting with a focus on low cost, low complexity in installation, operation and maintenance, and high reliability. A low-cost solarimetric station consists of compact equipment capable of providing global irradiance measurements and estimates for direct and diffuse components, as well as hemispheric photographs, with acceptable levels of uncertainty. The pyranometer periodically provides global irradiance information to the system, and the camera records photos of the sky. Using machine learning algorithms, and based on that information, the equipment provides estimates for direct and diffuse irradiance components. The equipment has other meteorological sensors, GPS, and wireless communication facilities. The equipment has an energy supply and management system consisting of a photovoltaic module, charge controller, and battery, which provide the energy necessary for the station to operate.

Abstract: The present invention relates to the injection of water and gas, either simultaneously or alternately, into subsea wells in order to enhance production and the oil recovery level. Thus, the present invention provides a subsea system for pressurizing a subsea oil reservoir injecting at least one of water and gas, comprising (i) at least two subsea injection wells (4, 4′), each subsea injection well (4, 4′) being connected to a production unit (5) by means of a single subsea line (1, 2) which is connected to the respective subsea injection well (4, 4′) by a main injection mandrel (6, 6′), and (ii) at least one jumper (3), each jumper (3) hydraulically connecting two of the at least two adjacent subsea injection wells (4, 4′) through annular mandrels (7, 7′). The present invention further provides a subsea reservoir pressurization method associated with the above-described system.
