  • Patent number: 11920448
    Abstract: An apparatus and method for electromagnetic heating of a hydrocarbon formation. The method involves providing electrical power to at least one electromagnetic wave generator for generating high frequency alternating current; using the electromagnetic wave generator to generate high frequency alternating current; using at least one pipe to define at least one of at least two transmission line conductors; coupling the transmission line conductors to the electromagnetic wave generator; and applying the high frequency alternating current to excite the transmission line conductors. The excitation of the transmission line conductors can propagate an electromagnetic wave within the hydrocarbon formation. In some embodiments, the method further comprises determining that a hydrocarbon formation between the transmission line conductors is at least substantially desiccated; and applying a radiofrequency electromagnetic current to excite the transmission line conductors.

  • Publication number: 20240018857
    Abstract: An apparatus and method for electromagnetic heating of a hydrocarbon formation. The method involves providing a producer well, which defines a longitudinal axis, between at least a first and second transmission line conductor. At a reference location along the length of the longitudinal axis, the first and second transmission line conductors are laterally spaced from the producer well by a first and second reference distance, respectively. At a second location, the first and second transmission line conductors are laterally spaced from the producer well by a third and fourth distance, respectively. At least one of the third and fourth distances are greater than the first and second reference distances, respectively. Excitation of the transmission line conductors generates an electromagnetic field having a reference shape and a reference position at the reference location and at least one of a more elongated shape and a different position at the second location.

  • Patent number: 8972277
    Abstract: A method of manufacturing a layered image assembly and a marketing method are provided including a passive consumer behavior tracking method without requiring an “opt-in” process. The layered image assembly includes a base layer and a top layer with an inner area formed between. An opening is provided within a perimeter of the base layer to provide access to the inner layer. The inner layer is provided with a media that may comprise coupons, offers, advertisements, collapsible springs, animated collapsible springs having an image, etc. The media may include one or more symbols for conveying information. The layered image assembly may be attached to an item, such as a substrate, envelope, package, magazine, etc. The customer information relating to the item may be associated, or merged, with the information from the one or more symbols from the media. This merging of information may be used to track customer purchases, customer information, and the like.

  • Publication number: 20100293821
    Abstract: A layered assembly is provided including a base layer and a top layer. A pouch area is located between the base layer and the top layer and is created by affixing the base layer to the top layer. An opening is provided within a perimeter of the base layer to provide access to the pouch area through the base layer. An item can be loaded into the pouch area. Once the layered assembly is affixed to a substrate, the opening of the base layer is sealed off from access. A peel-away portion is located within a perimeter of the top layer such that removal of a portion of the top layer along the peel-away portion provides access to the pouch area through the top layer. Removal of the peel-away portion reveals the item that is secured within the layered assembly.
