Brief project introduction
Drill cuttings and mud waste management is the principal concern in gas and oil drilling operations. Waste management is usually based on engineering activities to reduce waste and its impact on the surrounding environment. Oil and gas drilling waste management have two operational parts which include water recovery and waste treatment. Traditional methods are costly and unable to alleviate environmental concerns. A new method is proposed and organized to solve issues of pollution. The methods have been applied in Iran where there is particular demand due to high levels of pollution. The novel method is a complex of different processes that have not as yet been optimized or combined in an applied system of drilling waste management operations. In this term Drill cuttings and mud waste dumped into a new-designed corral/waste pit to separate water and condense them. Afterward, water is recovered by chemical treatments in cyclonic ponds and sends to the drilling rig. Solid remain in corral/waste pit biologically dried by adding composted material; then the dried solid bio-remediated throw the process of co-composting. Rejected waters of the treatments are sent to an SHDH (Solar Humidification Dehumidification desalination system ) which evaporates them by solar energy to produce fresh-water and salt. In 2019 this method used to reduce the environmental impact of the oil well drilling operation for MISOGPC (Masjed Soleiman Oil & Gas Production Company ), Subsidiary of NISOC, and the Iranian Department of Environment, HSE head of NISOC, and NIDC (National Iranian Drilling Company ) approved the functional results. The method produces soil, salt, and freshwater, and is shown to leave no adverse effects in local environments.
