  • Patent number: 9807663
    Abstract: When a user equipment performs inter-cell measurement, it may desire to measure signal quality and signal level of a source radio access technology (RAT) cell and a target cell. The signal quality measurement may be Squal and the signal level measurement may be Srxlev. Because Squal is not defined for TD-SCDMA, a new measurement criteria is defined to allow proper comparison of source RAT cell measurements with target RAT cell measurements when a user equipment is considering switching to a target cell.

  • Publication number: 20170275971
    Abstract: The present disclosure relates to a method and a system for extracting fluids comprising natural gas and water from a reservoir via at least one oil well/gas well connected to at least one flow line network. For extracting fluids, a composition containing a foaming composition is injected at a pre-determined location into the oil well/gas well and/or the flow line network. The foaming composition is then agitated with the water and converted to foam. The agitation is carried out by the natural gas. The foam formed reduces the interfacial surface tension between the natural gas and the water, and thereby facilitates reduction in liquid holdup in the oil well/gas well and/or the flow line network. The system of the present disclosure includes at least one manifold, at least one distribution assembly and a plurality of control valves and sensors.
