| A method is for use with subterranean formations, such as oil and/or gas reservoirs. In some examples (e.g., production examples), the method improves the production from that formation. Some of the examples of the method describe selecting both an exertive force (e.g., a pressure) to apply at a wellbore, but together with a drawdown pressure at the wellbore to modify operations (e.g., improve production) at that subterranean formation. The selection of one or both of the exertive force and drawdown pressure may be based on the downhole environment at that wellbore, which can include the porosity and/or permeability of a near-wellbore formation radially surrounding a wellbore. The exertive force and drawdown pressure may be specifically selected to modify the porosity and/or permeability of the near-wellbore formation. | ||||||

Procédé pour traiter une formation souterraine contre des venues de sable lors de la production d'un gaz issu de cette formation. On injecte aux abords du puits un volume VFT d'un fluide de traitement comportant au moins un polymère et de l'eau. Puis, on injecte un volume Vg de gaz pour chasser l'eau injectée aux abords du puits afin de reconnecter au puits le gaz de la formation. On réalise cette injection avec un débit choisi pour maintenir la saturation résiduelle en eau aux abords du puits maximale après reconnexion, de façon à favoriser la formation de ponts capillaires. Enfin, on assèche les abords du puits en poursuivant l'injection du gaz après reconnexion, de façon à favoriser la transformation de ponts capillaires en ponts adhésifs inter-grains. |
