Scale management during shale gas production
Shale gas hydraulic fracturing involves large volumes of water to complete the process; as a consequence of this, the water transportation, source water treatment, as well as flowback water and produced water management are important topics to be addressed in order to sustainably produce shale gas. It has been well documented that only approximately 10-40% of the fluids will be produced back to the surface, and that there will be an increased concentration of various ions in the flowback water during this process. The flowback water with high total dissolved solids and high concentrations of certain ions present a significant risk of mineral scaling.
This research aims to answer the question of what causes the high salinity in the flowback water, predict the scaling tendency during shale gas production and also give some recommendations on the shale gas scale management.
