For the environmental friendly treatment of well completion waste, we provide the integrated well completion and workover waste treatment technology of "oil removal + viscosity reduction and destabilization + solid-liquid separation + reuse", and its technical capabilities can cover operations in offshore oilfields and onshore oilfields need.
In-situ disposal to reduce waste transportation volume and end disposal pressure;
Customized treatment process design, suitable for a variety of well completion fluids systems;
Recovery of liquid phase can be repeated use
Auxiliary processing equipment - degreasing centrifuge.
The degreasing centrifuge has a high separation factor, which can effectively separate oil and water of oil-containing completion and workover fluids.
High-efficiency;
Skid mounted;
Run steadily;
Easy to handle;
