摘要： Methods and systems relate to the in-situ removal of heavy metals such as mercury, arsenic, etc., from produced fluids such as gases and crudes from a subterranean hydrocarbon-bearing formation. A sufficient amount of a fixing agent is injected into formation with a dilution fluid. The fixing agent reacts with the heavy metals forming precipitate, or is extracted heavy metals into the dilution fluid as soluble complexes. In one embodiment, the heavy metal precipitates remain in the formation. After the recovery of the produced fluid, the dilution fluid containing the heavy metal complexes is separated from the produced fluid, generating a treated produced fluid having a reduced concentration of heavy metals. In one embodiment, the dilution fluid is water, and the wastewater containing the heavy metal complexes after recovery can be recycled by injection into a reservoir.

摘要： A lower separator located below a submersible well pump intake has a labyrinth flow path, causing a first well fluid separation of lighter components from heavier components as well fluid flowing into the lower separator turns downward to flow toward a lower separator heavier component port. A bypass riser has a bypass riser inlet below the pump intake and a bypass riser outlet above the pump intake. A lighter component conduit communicates the bypass riser inlet with lighter components of the first well fluid separation, causing a second well fluid separation at the riser outlet as a heavier portion of the lighter components flowing up the riser turn to flow downward to the pump intake. A heavier component conduit bypasses the bypass riser inlet and delivers the heavier components of the first well fluid separation to the pump intake.

摘要： Downhole Electric Submersible Pumps (ESP) in a production string often experience gas lock caused by free gas present in the production liquids which reduces intake pressure below the operating parameters of the ESP. A gas compression separator assembly, having a series of compressors and separation chambers, entrains or dissolves the free gas component of the production fluid and separates free gas for downhole disposal. The production fluid fed to the ESP intake has an increased fluid pressure, a reduced volumetric fluid flow, and a lower free gas content, and is less likely to induce gas lock of the ESP.

摘要： Downhole Electric Submersible Pumps (ESP) in a production string often experience gas lock caused by free gas present in the production liquids which reduces the intake pressure below operating parameters of the ESP. A compressor is disclosed for compressing production fluid prior to feeding the production fluid into an ESP intake. The compression entrains or dissolves free gas into the production liquid, reducing the risk of gas lock of the ESP. The compression increases production fluid pressure to within the operating pressure of the ESP intake, to a selected pressure, or to above the free gas bubble point.

摘要： A gas separator for separating gas from a fluid in a production stream in a producing hydrocarbon well is described. The gas separator includes a central tube sized to fit into a well casing of the producing hydrocarbon well and having an input at its lower end for receiving the production stream and perforations at its upper end to allow the production stream to flow into the space between the central tube and the well casing. A suction tube is located inside the central tube, the suction tube is operable to draw fluid from the space between the central tube and the well casing and to deliver the fluid to an artificial lift mechanism. A baffle assembly in the gas separator is comprised of a series of baffles, each baffle extending between an inner wall of the central tube and an outer wall of the suction tube for a portion of the available space between the inner wall of the central tube and the outer wall of the suction tube, each baffle offset from the other baffles in the baffle assembly, wherein the baffle assembly is operable to continually redirect the fluid and gas as it travels through the central tube.
