Abstract: A method for separating a part blank from a support, wherein the support and the part blank are manufactured by additive manufacturing. The support includes an inner cavity containing a fluid. The separation method includes a heating of the support to deform the support by fluid expansion in the inner cavity until the support is separated from the part blank.

Abstract: The invention relates to a production simulation process by pilot test in a deposit (1) of hydrocarbons contained ina reservoir (2) with the aid of injection wells (3b, 5b; 7b) and producing wells (4b, 6b, 8b) with horizontal drains, said drains forming, at least in part, a polygonal geometric shape in one plane of the reservoir.By the simulation process:a first state is triggered either by injection or by production for the drains located at the periphery of said geometric shape,a second state, opposite said first state, is triggered either by injection or by production for the drains located inside said geometric shape.the volumetric flowrates of liquid injected and produced are regulated such that the sum of the flowrates of the injection drains is substantially equal to the sum of the flowrates of the production drains.

Abstract: A process for the assisted recovery of heavy hydrocarbons from an underground formation having a plurality of superimposed reservoirs for the hydrocarbons involves arranging horizontal sections of a plurality of wells so that a first well of a first series of wells extend into a reservoir and is located essentially vertically below a horizontal section of a second well located in an immediately adjacent reservoir, with the first well being used as a steam injection well and the second well being used as a hydrocarbon-producing well.

Abstract: A method for positioning at least one plug, or screen, between two fluids in a geological formation, a product intended to form said plug being injected through at least one substantially horizontal plane situated in the vicinity of the interface formed by said two fluids.
