Abstract: The invention is a method for exploitation of a sedimentary basin containing hydrocarbons using basin simulation. Based on a reconstitution of the formation of the first of the layers of the basin, a conjoint basin simulations of at least one of the layers underlying the first layer. A conjoint geomechanical simulation of the first layer and the at least one underlying layer is then carried out. If the deviation between some of at least some parameters from the geomechanical simulation and those from the basin simulation is above a predefined threshold, the previous steps are repeated applying a correction to the basin simulation. The basin is then exploited as a function of the results of the basin simulation. The invention applied to exploration and exploitation of the basin.

Abstract: Method for exploitation of a sedimentary basin containing hydrocarbons by means of a basin simulation. On the basis of a reconstitution of the formation of the first of the layers of the basin, for at least one of the layers underlying the first layer, a conjoint basin simulation of the layer concerned and at least one underlying layer is carried out. A conjoint geomechanical simulation of the layer concerned and at least one underlying layer is then carried out. If the deviation between some of the parameters from the geomechanical simulation and those from the basin simulation is above a predefined threshold the previous steps are repeated applying a correction to the basin simulation. The basin is then exploited as a function of the results of the basin simulation. Application in particular to the exploration and exploitation of hydrocarbon deposits.

Abstract: Method of treating the area surrounding an acid gas storage well (1) using a reactive solution, wherein the following stages are carried out: a) injecting from the well a wash fluid for washing the rock of said surrounding area so that it no longer contains products reactive with said solution, b) injecting into the rock thus washed a predetermined volume of reactive solution suited to react with acid gases.
