  • Patent number: 11288465
    Abstract: Disclosed is a system and method for wirelessly monitoring 5 process conditions within a reactor vessel. A plurality of sensor-enabled radio frequency identification (RFID) tags are disposed at known locations throughout a catalyst bed of a vessel and are used to measure various conditions within the vessel. The sensor-enabled RFID tags are encoded with individual identification codes and are wirelessly linked to a transceiver. A transceiver 10 provides for the interrogation of each sensor-enabled RFID tag to receive responsive transponder signals that carry information representative of both the three-dimensional location of the sensor-enabled RFID tags and the sensed conditions within the reactor. This allows for three-dimensional profiling of the specifically measured condition within the reactor.

  • Patent number: 11280923
    Abstract: Receiver-consistent scalars of seismic receiver channels are used for time-lapse monitoring of a sub-surface earth formation. Signals are induced by seismic waves propagating through the earth formation adjacent to each respective seismic receiver channel. Each seismic receiver channel is acoustically coupled to the earth formation as present directly adjacent to the location of the seismic receiver channel in question. The base receiver-consistent scalars and the monitor receiver-consistent scalars of seismic receiver channels can be outputted to reveal changes in these receiver-consistent scalars. These changes can be used to delineate information about physical changes in the subsurface earth formation. The changes in the based receiver-consistent scalars and the monitor receiver-consistent scalars may be displayed visually.

  • Patent number: 11255166
    Abstract: Migration of formation solids in a wellbore is restrained by feeding a slurry, comprising water, a viscosifier, and a concentration of cement clinker particles, into the wellbore, and hydrating the clinker particles in the wellbore. The clinker particles are kept in suspension during the hydrating, and upon completion of the hydrating the hydrated clinker particles form a hardened cement consisting of a permeable structure of interconnected hydrated clinker particles. A layer of degradable lost circulation material (LCM) may be employed to separate the slurry with clinker particles from the formation surrounding the wellbore during hydrating of the clinker particles.
