Abstract: A downhole completion system and methodology is provided for use in a well. The downhole completion comprises a packer and a plurality of flow control sand screens. Each flow control sand screen has an inflow control device (ICD). The downhole completion further comprises at least one lower sand screen positioned below the plurality of flow control sand screens. The at least one lower sand screen is configured without an ICD. A flow restrictor is disposed between the plurality of flow control sand screens and the at least one lower sand screen.

Abstract: A method and a system for generating personal promotion codes from the computing resources of a provider of services. Internal promotion codes including a family ID field and serial ID field of alphanumeric characters are first generated. The internal promotion codes are then encoded into a corresponding series of external promotion codes of alphanumeric characters, which render the internal promotion codes unintelligible. After which the series of external promotion codes is packed into an encrypted file which is forwarded to a client application of the provider of services to have the external promotion codes distributed to its customers. The external promotion codes later submitted to the client application by the customers are further validated by the provider of services. Validation of the external promotion codes submitted by the customers does not require that all generated external promotion codes need to be stored in a database of the provider of services.

Abstract: The present invention relates to devices for displacing two bodies relative to each other. The device of the invention is made up of two pieces respectively associated with the two bodies, a mechanism for applying a force between the two pieces, a projecting portion secured to the piece, a cavity complementary to at least a part of the projecting portion formed in the other piece, the pieces being displaceably mounted relative to each other in such a manner that the projecting portion engages in the cavity, the piece in which the cavity is formed being of a first material that is suitable for passing from an undeformable hard first state to a deformable soft second state, while the piece which is secured to the projecting portion is of a substantially undeformable second material, and a controller for controlling the passage of at least the portion of the first material that surrounds the cavity from the first state to the second state, and vice versa.
