Traitement par Acidification Champ Hassi GuettarWest

Abstract

The objective of acidification treatment is to eliminate damage to the well surroundings and restore the initial permeability of the layer, but it would be wrong to conclude that injecting an acid into a sedimentary formation always leads to improved production. An acid performance study was carried out on a HGAW2 well with different mineralogies, for the purpose of remedying of clogging around the well. A test on this well to determine this phenomenon is established in order to predict well production. Recommendations are suggested for the wells, subsequent acid stimulation operations and the HGAW2 field as a whole
