Hengyang owns mobile and fixed units which can be integrated to treat cuttings, wastes and residues resulted from drilling operations, based on requirement and location.
The water from the treatment process will be analyzed in the laboratory and the lab results report will be used to determine the optimum removal methods, based on the conditions existing on site, on the laws of the respective country and taking into account the cost optimization through the following: vaporization, injection into the well, discharge into available sewers or into natural emissaries.
The solid fraction remaining in the sludge pit after fluid extraction and treatment, depending on the contaminant found by lab analyses, will be disposed in accordance with the local applicable law and with the best techniques available: screening, washing, solidification, stabilization, disposal, etc.
At the end of the drilling fluids and sludge treatment operations, at the beneficiary`s request, the site can be restored to the natural circuit.
