An apparatus for separating solid particles from a hydrocarbon-containing fluid produced from an oil and/or gas production facility, the apparatus comprising a primary production conduit having an upstream portion and a downstream portion, at least one valve connected to the upstream portion, the valve having a first outlet in fluid communication with the primary production conduit, a second outlet in fluid communication with a solid particle separation unit and an inlet connectable to an oil and/or gas production well, wherein the first and second outlets of the valve are selectively connectable to the upstream portion or the solid particle separation unit, and the valve being actuatable to select between the respective first and second outlets, the solid particle separation unit comprising at least one solid separator and having a first output for solids and a second output for fluids, the second output being in fluid communication with an input of a fluid separator having a liquid output and a gas output, the liquid output being in fluid communication with the downstream portion by a return conduit, a controller for controlling liquid flow from the fluid separator to the downstream portion along the return conduit and a pressure boosting pump in the return conduit for pressurising liquid in the return conduit and pumping the pressurised liquid in the return conduit in a direction from the fluid separator to the downstream portion, the controller being adapted to control any one or more, in any combination, of any of an output pressure of the pump; a flow rate of the pump; and an on/off function of the pump. There is also disclosed a method of separating solid particles from such a hydrocarbon-containing fluid. There is also disclosed a system and method of removing solids from an oil well by fluidising the solids. |
