Abstract: The present invention is a method for determining an optimal speed of a first vehicle preceded by a second vehicle. Position, speed and acceleration of the second vehicle are measured in order to determine a trajectory thereof, and a dynamic model of the first vehicle is constructed. The optimal speed is then determined by minimizing the energy consumption of the vehicle by use of the dynamic model by minimization being constrained by the trajectory of the second vehicle.

Abstract: The invention relates to a method for recovery of hydrocarbons in a geological reservoir by injection of a low-salinity aqueous solution. A representative model of the evolution of the flow parameters as a function of the aqueous solution salinity is calibrated by use of laboratory measurements performed on a rock sample from the reservoir for at least two salinity values. Then, by use of a flow simulator including the calibrated model, the injection of aqueous solutions into the sample is simulated, with and without capillary effects, for at least the two salinity values with a microscopic residual oil saturation being determined for each salinity value. Then, from the flow simulator including the calibrated model and the microscopic residual oil saturation values, a reservoir development scheme is determined with hydrocarbons of the reservoir being exploited according to the development scheme.

Abstract: The invention relates to a composition C which comprises, in an aqueous medium M: surfactants suitable for creating a foam in the presence of a gas; and polymers P based on acrylamide or acrylamido units, having a molecular mass of 1,000,000 to 20,000,000 g/mol; or: composition C has a viscosity of less than 6 mPa·s; and the content of polymer P is greater than the concentration limit beyond which the apparent viscosity of a foam obtained from composition C is greater by at least 10% than the apparent viscosity of a foam obtained from the same composition but deprived of polymers. The invention further relates to the use of these compositions as foaming compositions for EOR.

Abstract: The present invention is based on the use of a two-step hydrocracking process comprising a step of hydrogenation placed upstream of the second hydrocracking step, the hydrogenation step treating the unconverted liquid fraction separated in the distillation step in the presence of a specific hydrogenation catalyst. Furthermore, the hydrogenation step and second hydrocracking step are carried out under specific operating conditions and in particular under very specific temperature conditions.
