Abstract: The present invention concerns a method for cleaning a filtration system under operation. The filtration system comprising a hydraulic circuit Cp recycling the permeate stream to the feed side of the membrane and/or a hydraulic circuit Cr recycling the retentate stream to the feed side of said membrane. The method comprises injecting an amount of a chemical product into the filtration system in the hydraulic circuit Cp or in the hydraulic circuit Cr or upstream of the cross-flow filtration membrane, setting the proportion of recycled permeate stream or recycled retentate stream collected in the hydraulic circuit Cp and/or Cr to enable the recycling of a significant amount of unreacted chemical product having passed through said cross-flow filtration membrane to the feed side of said cross-flow filtration membrane, as well as a filtration system for carrying out said method.

Abstract: The present invention relates to a method of modelling channel ways. In particular, this method comprises steps for determining a set of stochastic channelway trajectories as a function of a local directional component and of a trigonometric component and for providing the determined trajectory of the channel way which complies with a certain number of constraints. A point of one of the trajectories belongs to an entry constraint. Finally, the set of trajectory constraints is complied with by the determined set of trajectories.

Abstract: A method, apparatus, and program product to determine distribution of a plurality of components amongst a plurality of phases for a multi-component, multi-phase system including a multi-component, multi-phase fluid. A plurality of phase boundaries of the multi-component, multi-phase fluid and a vapor-liquid equilibrium (VLE) are determined based on a plurality of geophysical parameters associated with an oilfield and using one or more computer processors, including by determining hydrocarbon partitioning in a water phase, based in part on applying empirical equilibrium multi-phase mole fraction ratios (K-values) of the multi-component, multi-phase system that are functions of temperature and pressure only. In addition, an amount of at least one fluid component distributed in a plurality of phases of the multi-component, multi-phase system is predicted by solving a set of flash equations with the one or more computer processors based on the plurality of phase boundaries.

Abstract: The present invention relates to a liquid evacuation device for an extraction well. The device comprises a tank presenting a liquid accumulation area. The tank is connected to a gas evacuation tubing. An insulant limits a flow of fluid between a wall of the tank and a wall of the well, from a first space formed between the insulant and the well bottom to a second space formed between the insulant and the well head. A first opening on the tank enables circulation of a gas-liquid mixture from said first space to a third space formed in the gas evacuation tubing. A second opening on the tank enables circulation of fluid from said second space to the liquid accumulation area. The first opening is made between the liquid accumulation area and the connection to the evacuation tubing.

Abstract: The invention relates to a method for detecting and locating hydrocarbon deposits under a body of water in several steps. First, images of a surface of the body of water taken at different times are acquired. Next, for each image, traces of hydrocarbon leaks are identified. Next, a detection map is generated. This map indicates probabilities of the presence of a hydrocarbon leak around the identified traces. The map is obtained by processing the image at least based on a criterion of distance to the identified traces. Finally, the detection maps are combined to produce a hydrocarbon leak location map.
