The invention is a method for operating a hydrocarbon deposit by injection of gas in foam form, comprising determining a model of displacement of the foam which is a function of an optimal mobility reduction factor of the gas and at least one interpolation function dependent on a parameter and constants to be calibrated. The mobility reduction factor of the gas is determined and the constants of at least one interpolation function are calibrated from experimental measurements comprising injections of gas in non-foaming form and in foam form into a sample of the deposit for different values of the parameter relative to the function being considered. Measurements of headloss corresponding to each value of the parameter of the interpolation function are considered. The calibration of the constants is performed interpolation function by interpolation function.

Applicable notably to oil exploration and operation.

A method of producing a container product comprises providing a mold including a first part and a second part. The mold is closed to define a cavity having a first area and a second area. A molten plastic composition including a polymer and a physical blowing agent is filled into the cavity. Then, the molten plastic composition in the cavity is cooled, such that the molten plastic composition in the first area is completely cooled and solidifies or a central portion of the first area has micro uncooled molten plastic composition. The second area has the plastic composition in the molten state. The first part of the mold is moved in the axial direction. The molten plastic composition in the second area forms a beehive foam after foaming and expansion. Then, the foamed container product in the mold is cooled to take shape and then removed after opening the mold.
