摘要： A method of cleaning an oil or gas well includes mixing a caustic with a saline solution to precipitate hydroxide species from the saline solution and form a milky suspension. The suspension is contacted with contaminants in a well bore to entrap the contaminants. A polymeric flocculant is then mixed with the suspension in the well bore to aggregate the hydroxide species and the entrapped contaminants into flocs. The flocs are extremely strong and can withstand the highly turbulent flow existing in the well bore and can be readily flushed out of the well bore.

摘要： A damage-resistant filter for use in subterranean wells has at least one layer of a filter medium, such as a sintered supported porous membrane, coaxially disposed about a perforated support member. The filter may also include a drainage layer disposed between the inner support member and the filter medium, and a protective covering, such as a perforated cage, surrounding the filter medium. The filter is particularly suitable for removal of sand and other particulates from fluids produced in a well.

摘要： An oil or gas well cleaning method includes inserting tubing, such as a coiled tubing, into a well bore, for example, into a production pipe in a well bore. A cleaning fluid containing a flocculant is passed into the well and the flocculant in the cleaning fluid is mixed with solid particles in the well bore to flocculate the particles. The cleaning fluid and the flocculated particles are then removed from the well. In one embodiment, the cleaning fluid containing the flocculant is discharged from the lower end of the tubing into the well, and the cleaning fluid with the flocculated particles is removed from the well via the production pipe. Alternatively, the cleaning fluid containing the flocculant may be introduced into the well through the production pipe, and the cleaning fluid with the flocculated particles may be removed via the tubing. The flocculant may also serve as a friction reducer to reduce friction between the cleaning fluid, the solids, the production pipe, and the tubing.

摘要： The invention relates to a process for removing sulfur particles from an aqueous catalyst solution used to remove hydrogen sulfide from a gas stream (1, 5), comprising the steps of directing a flow of a suspension (12) comprising reduced catalyst solution and sulfur particles to an oxidizer zone (20), where the catalyst solution is regenerated by contacting said suspension with a gas (22) containing oxygen; and removing sulfur from said suspension at least by gravity sedimentation at a bottom (21) of said oxidizer zone (20). According to the invention a flow deflecting means (34) is disposed at least at an outlet (35) for the oxidized catalyst solution leaving said oxidizer zone (20) such as to prevent any turbulent state caused at least by a stream of oxidized catalyst solution leaving said oxidizer zone (20) such as to reduce foaming and plugging of the whole system. A gas (27) is additionally injected at the conical bottom (21) of the oxidizer zone (20) in parallel to said slanted surface (23) for avoiding sedimentation and agglomeration of sulfur particles on said bottom (21). Heavy hydrocarbons are eliminated to further reduce foam production. Further, foaming and plugging is controlled by using proper packings in the absorber. Proper controls are used to avoid flooding. The temperature is adjusted such that not only the reaction rate in the oxidizer is high, but also the catalyst degradation is kept low. Thus excessive foaming and flooding of the oxidizer zone is avoided.

摘要： A Process for hydroconverting of a heavy hydrocarbonaceous feedstock comprising a catalyst to produce lower boiling hydrocarbon products. The method can be used for the high-boiling point residues of oil refining (asphaltene, the residues of vacuum and under pressure distillation of oil, and the useless and heavy materials of thermo catalytic processes), heavy oil, natural bitumen, and bitumen-containing sands. It can also be used in oil refinery industries for the production of gas, gasoline fractions, distillation gas oil, concentrate of ash containing metals and chemical fertilizers. The process overcomes disadvantages like low conversions, coke production during the reaction, touchiness to the feed (to the metals and solids present in the feed which deactivate the catalyst), high investment and operational costs and the need for pre-purification units, for the elimination of heavy substances.
