Produced Water Treating & Disposal in to Injection Well

Produced Water Treating & Disposal in to Injection Well

Description :

This special practical approach training is designed to provide a comprehensive under-standing of oil field water technology, especially produced water treating and disposal and to match injection well. Each equipment and operations considerations base on basic concept of prevention of the system plugging and the need and regulation on water disposal to injection well and offshore environment.

After completing of this training, participants will better understand and analyze specific water quality, in-field water treating and disposal scheme and operations, configuration and operational mechanism of each equipment, test methods and procedures, and improve skill and ability to diagnose water treating system performance and utilize laboratory analyses results.
 

Outline :

1.   Operational and Environmental Problems in Produced Water Disposal
- Treatment difficulties caused by incompatible mixing of produced water
- Plugging of injection well and clogging of perforation caused by inorganic scale deposition
- Formation & down-hole damage caused by invasion of rock by fine solids, clay swelling and peptization
- Malfunction of surface equipment, pumps and valves caused by sand, debris and dirt
- Slug flow in pipeline caused by sludge, slime, solids, oil and gases
- Microbiological Induced Corrosion caused by specific bacteria activity
- Pipeline, equipment and injection well corrosion caused by acid gases and air in produced water
- Environmental problems caused by sludge, residual additive chemicals, hazardous components and residual oil in produced water

2.  Guidelines for Disposal of Produced Water by Injection
- History and current status of target injection formation
