Abstract: The invention relates to a device (30) for extracting a straw (100) from a container (1) closed by a lid (3) and presenting an orifice (17). The device (30) comprises: a stopper (37) suitable for being attached to and detached from the lid (3) in order to close and open the orifice (17); and a body (31) connected to the stopper (37) and suitable for being inserted inside the container (1) through the orifice (17), and including: an abutment (35) on which a corrugated portion (105) of the straw (100) is suitable for resting when the stopper (37) is attached to the orifice (17), and which is suitable for entraining said corrugated portion (105) while the stopper (37) is being detached in order to extract the straw (100) from the container (1) through the orifice (17); and at least one opening (34) through which the straw (100) can be disengaged from the device (30) when the stopper (37) is detached from the lid (3).

Abstract: A method for enhancing a physical parameter map in a zone of a seismic image. The dip of points of the image is obtained. For one of these points, called second point, a correction factor of a physical parameter is obtained with a residual move-out algorithm from a common image gather. A first point is selected on a line substantially perpendicular to the dip at the second point. The selection, involves at least one parameter among whether the difference between the dip at the second point and the dip at the first point is below a first preset value; and the spacing between the first and the second point is below a second preset value. An inversion algorithm gives a corrected interval value of the physical parameter to update the physical parameter map.
