Abstract: On-stream catalyst replacement apparatus for countercurrent upstream flow of a gas and hydrocarbon liquid through a downward moving catalyst bed in a reactor vessel. A mixed feed stream of gas and liquid hydrocarbon components enters a reservoir formed between the lower end of the reactor and a conical screen supporting the lower end of a catalyst bed. A wall across the vessel divides the reservoir into a lower surge chamber for receiving the mixed feed and an upper plenum chamber for separating the components into alternate feed rings of gas and hydrocarbon liquid under the conical screen. The mixed feed enters the plenum chamber through a plurality of tubes extending downwardly from the wall to the same depth in the surge chamber that prevents establishing preferential paths for gas to independently enter the plenum chamber.

Abstract: A method of using oriented seismic sensors to delineate the surface of a geologic unit having an anomalous velocity, such as salt dome is disclosed. Seismic sensors having three orthogonal axes of sensitivity are sealed in a housing and are attached to the outside of a tubing means. The tubing means is lowered into a wellbore that penetrates the geologic unit to a known depth, and a liquid such as cement is pumped through the tubing and up the annular space to fixedly attach the sensors to the geologic formation. The orientation of the sensor axes can then be calculated from an observed orientation of the reference directions of the sensor housings. Seismic wavefields are then propagated through the geologic unit and the surrounding earth, and are observed by the sensor axes of sensitivity, and are recorded and transmitted to the top of the tubing.
