Complex Fracture Networks Prohibit Safe Fracturing Fluid Recovery
Engineering Reports, Volume 7, Issue 2, February 2025.ABSTRACT The recovery of fracturing fluid (HF), necessary for subsurface energy production and carbon storage, is generally low, raising concerns about HF fate in the subsurface and its potential to contaminate water aquifers. This study examines the migration of fracturing fluid and tracks its distribution in fractured reservoirs using a two ...
