Contaminant extraction in a borehole
The present invention relates to a system for contaminant extraction in a borehole extending from a surface of the Earth through a water permeable layer and into an underlying production zone, the system comprising: an outer casing located within the borehole and extending through the water permeable layer; a production pipe located within the casing and extending towards the production zone; a filter assembly occupying at least part of an intermediate zone between the outer casing and the production pipe, wherein the filter assembly is configured to capture contaminants before they enter the water permeable layer and/or before they are released into the atmosphere, the filter assembly comprising: a lower solids filtering stage configured to filter solid contaminants; and an upper fluids filtering stage configured to filter fluid contaminants migrating from the production zone through the lower solids filtering stage; and sealing means for preventing the uncontrolled leakage of contaminants from the intermediate zone. Methods for contaminant extraction, a contaminant filtration system and solid and fluid filter modules are also disclosed.
