Abstract: Methods and systems are disclosed to determine a permeability value and a permeability image of a rock. The process can include determining labeling of a 3D segment of a rock. The labeled segments can be determined using, for example, computer vision and machine learning and can be used to determine a grain size of a 3D rock segments. The grain size value can be used to determine a permeability value for the 3D rock segment. The permeability value of the 3D rock segment can be used to determine the heterogeneous permeability of the rock.

Abstract: A tank includes a secondary insulation barrier, a secondary sealing membrane resting on the secondary insulation barrier, a primary insulation barrier resting on the secondary sealing membrane, a primary sealing membrane resting on the primary insulation barrier, and a primary reinforcing member. The primary sealing membrane includes primary corrugations and the secondary sealing membrane includes secondary corrugations projecting toward the interior of the tank.
