Abstract: The invention notably relates to a computer-implemented method of machine-learning a predictive model configured for predicting a concentration of an element in produced water of a given well of hydrocarbon production in a hydrocarbon reservoir having wells of hydrocarbon production. The method comprises providing a dataset comprising values of one or more geoscience well-wise variables. Each value corresponds to a respective well of hydrocarbon production in the hydrocarbon reservoir other than the given well. Each value that corresponds to a respective well is associated to a respective ground truth value representing a concentration of the element in the respective well. The method further comprises learning the predictive model based on the dataset. This forms an improved solution for predicting a concentration of an element in produced water of a given well of hydrocarbon production in a hydrocarbon reservoir.

Abstract: The invention relates to a modular installation for the treatment of an aqueous stream of produced water from an oil or gas field, said aqueous stream comprising water, suspended solids, residual hydrocarbons, at least one metal to be recovered and a first metal different from the metal to be recovered, the installation comprising: one or more movable metal treatment tanks (1) configured to precipitate the first metal in the aqueous stream; a filtration container (4) comprising a filtration unit (4c) configured to remove at least part of the suspended solids; and a separation container (6) comprising power and fluidic connectors, configured to receive and be connected to a separation unit (6c), the separation unit (6c) being configured to separate the metal to be recovered from the aqueous stream; the one or more movable metal treatment tanks (1), the filtration container (4) and the separation container (6) being fluidically connected, and the filtration container (4) being arranged downstream of the one or

Abstract: The invention notably relates to a method for performing a 3D structural restoration of a geological setting with a computer system, including unfolding one or more geological surfaces of the geological setting. The unfolding comprises for each respective geological surface providing a 3D triangulated surface representing the respective geological surface, and determining a conformal flattening that transforms the 3D triangulated surface into a 2D triangulated surface. The conformal flattening is an iso-topographic mapping which substantially preserves angles. This provides an improved solution of 3D structural restoration of a geological setting.
