    Abstract: A method and system for drilling a wellbore is described. The system includes a wellbore with a variable density drilling mud, drilling pipe, a bottom hole assembly disposed in the wellbore and a drilling mud processing unit in fluid communication with the wellbore. The variable density drilling mud has compressible particles and drilling fluid. The bottom hole assembly is coupled to the drilling pipe while the drilling mud processing unit is configured to separate the compressible particles from the variable density drilling mud. The compressible particles in this embodiment may include compressible hollow objects filled with pressurized gas an configured to maintain the mud weight between the fracture pressure gradient and the pore pressure gradient. In addition, the system and method may also manage the use of compressible particles having different characteristics, such as size, during the drilling operations.

    Abstract: The use of one or more alkali metals, preferably sodium, to remove sulfur from hydrocarbon streams containing up to about 100 wppm sulfur. The hydrocarbon stream is introduced into a reactor where it is contacted with one or more alkali metals. The treated hydrocarbon stream is then subjected to a water wash thereby resulting in an aqueous phase fraction and a hydrocarbon phase fraction. The aqueous phase fraction, which is separated from the hydrocarbon phase fraction contains water-soluble sodium moieties.

    Abstract: This invention relates to reactors with mitigation of fouling-related pressure buildup, the reactors having a reactor bed containing at least one catalyst layer through which reactants flow. The mitigation of fouling which occurs at the top of the reactor bed is accomplished by using at least one blowback ring located near the top of the reactor bed.

    Abstract: A hydroprocessing process for removing impurities from a feed comprising a hydrocarbonaceous liquid comprises at least one cocurrent, upflow hydroprocessing reaction stage, a vapor-liquid contacting stage and a downflow hydroprocessing reaction stage. The feed and hydrogen react in the upflow stage to produce a partially hydroprocessed liquid and vapor effluent. The vapor contacts a hydrocarbonaceous liquid in the contacting stage, which transfers impurities from the vapor into the liquid. The impurity-enriched contacting liquid mixes with the upflow stage liquid effluent and the combined liquid effluents react with hydrogen in the downflow reaction stage, to form a hydroprocessed product liquid and vapor effluent. Additional product liquid is recovered by cooling and condensing either or both the contacting and downflow stage vapor effluents.
