A communication interface device includes a wireless Internet packet transceiver and a PCMCIA card electrically connected to the transceiver. The methods may include the steps of heating potentially extractable hydrocarbons, such as high viscosity oil, by injecting a sufficient amount of a heating fluid having a temperature and viscosity sufficiently high to minimize channeling and to permit penetration into regions of the reservoir containing the potentially extractable hydrocarbons. A first portion of the sleeve extends around the lower part and opposite sides of a wearer’s hand and wrist and has spaced side edges located in an upper region of the sleeve. Other features are also provided.
