Before putting the well on ,flowback,, the induced fractures are occupied by the compressed ,fracturing fluid,. Therefore, analyzing the produced ,fracturing fluid, should in principle be able to characterize the induced fractures, and complement the production data analysis. We develop a rate transient model for describing the ,fracturing fluid flowback,.

Ammonium chloride | NH4Cl - PubChem

1. Expectorant in cough syrups. 2. The ammonium ion (NH4+) in the body plays an important role in the maintenance of acid-base balance. The kidney uses ammonium (NH4+) in place of sodium (Na+) to combine with fixed anions in maintaining acid-base balance, especially as a homeostatic compensatory mechanism in metabolic acidosis. The therapeutic effects of ,Ammonium Chloride, depend upon the ...
