A new method for drilling waste management basedon composting and solar desalination

Drilling cutting and mud waste are considered as saline or super salineslurries, and management of them is the main environmental concern for gas andoil drilling operations. The oil and gas drilling waste management methods havetwo main operational parts which include water recovery and waste treatment.However, the traditional methods costly and unable to wipe all the environmentalconcerns, so, a new method invented and organized to reduce these concernsby authors. By approval and cooperation of the National Iranian Oil Company(NIOC), the method fully operated in Nafte Sefid, ShuShtar County, Khuzestanprovince, Iran for Masjed Soleiman Oil & Gas Production Co. (MISOGPC),Subsidiary of National Iranian South Oil Company (NISOC) in 2019. This newmethod showed good operational performance, according to NIOC considerationand showed a new innovative way to reduce the environmental impacts of oil(gas) well drilling. In conclusion, it should mention, this new method is a complexof different processes which never used as the same system for drilling wastemanagement operation. This invented method based on biological remediation,chemical water treatment and solar desalination, and at the bottom, produce soil,salt and freshwater, also, left no bad trace in the environment.
