Etude de l’efficacité du traitement chimique de sulfate de baryum dans le champ de Hassi Messaoud

Abstract

Barium sulphate deposits pose dangerous problems in the production of hydrocarbons. This type of deposit occurs when the water injected for the recovery of hydrocarbons is incompatible with the formation water. The objective of this work is to study the inhibition of barium sulphate deposits by anti-AD32 deposits and determine the effectiveness of the latter compared to other inhibitors. Initially, we studied the case of the two wells MD413 and MD633, and by analyzes of identification of the deposits of BaSO4 were carried out at the laboratory level of SONATRACH DP (IRARA), We noticed the inefficiency of the other inhibitors (CHIMEC1264). Next, the performance of an industrial test at the level of an MD480 pilot well also proved the inefficiency of the anti-deposition GYPTRON SA 860 N. The inefficiency of other anti-depots caused considerable economic losses.
