Abstract: An electronic device for mounting on a support rail, has a housing, an electronic unit arranged in the housing, and an elastic contact element that serves in the electrically-conductive connection between the electronic unit and the support rail. The contact element has two contact legs, a connecting area connecting the contact legs to one another, and a contacting section connected to the connecting area for making contact with the electronic unit, and wherein when the electronic device is in the mounted state, the contact legs of the contact element make contact in a clamping manner with a leg of the support rail in-between. The contact element arranged ensures, with small size, good electrical and mechanical contacting of the support rail. The sides of the two contact legs facing one another form a short contact area. The first contact area on is sharp-edged, and the second contact area forms a swivel.

Abstract: Performing an enhanced oil recovery (EOR) injection operation in an oilfield having a reservoir may include obtaining a EOR scenarios that each include a chemical agent, obtaining a three-dimensional (3D) porous solid image of a core sample, and generating a 3D pore scale model from the 3D porous solid image. The core sample is a 3D porous medium representing a portion of the oilfield. The 3D pore scale model describes a physical pore structure in the 3D porous medium. Simulations are performed using the EOR scenarios to obtain simulation results by, for each EOR scenario, simulating, on the first 3D pore scale model, the EOR injection operation using the chemical agent specified by the EOR scenario to generate a simulation result. A comparative analysis of the simulation results is performed to obtain a selected chemical agent. Further, an operation is performed using the selected chemical agent.
