Abstract: Methods and systems for removing near wellbore damage in a hydrocarbon reservoir are described. In one example implementation, an antenna is positioned inside a wellbore in a location corresponding to a formation where near wellbore damage occurs. The wellbore extends from a surface of a hydrocarbon reservoir downward into the subterranean structure of the hydrocarbon reservoir. An electromagnetic (EM) wave is transmitted to the antenna. A portion of the EM wave is irradiated at the formation. The portion of the EM wave removes the near wellbore damage at the formation.

Abstract: Architecture that provides enhanced tag telemetry in a microblogging communications infrastructure. The architecture provides efficient discovery and tracking of topics that are of interest to a specific user by enabling users to follow (track) hash tags (#tag) and to receive and view all messages tagged with the hash tag appear in the user's personal feed. Each hash tag has a persisted tag page that aggregates all the associated activity, and includes a list that includes, but is not limited to, the tag followers, the most frequent user (uses the tag the most often in a specific time frame), a description, related tags, for example. The user can receive all the updates in the user's personal feed, and see an aggregation of all the messages and conversations associated with the tag in single place. The user can also mute the tag to prevent the receiving of tag information.

Abstract: Methods and systems disclosed here include conducting two pressure-dependent permeability tests having the same range of effective stress but two different values of pore pressure. For the test with the higher pore pressure, the permeability is only impacted by the mechanical deformation of the rock, while for the one with lower pore pressure the permeability is impacted by both mechanical deformation of the rock and the Knudsen diffusion. By using the same range of effective stress, the contribution from the mechanical deformation of the rock should be the same. Therefore, by subtracting the permeability with higher pore pressure from the one with lower pore pressure, the impact of Knudsen diffusion and the mechanical deformation of the rock can be determined.
