Optimum acid system for Trengganu offshore gas well acidizing process
Formation damage usually occurs drilling operation, chemical treatment and etc. Drilling fluids causes the most common formation damage. In order to repair this damage, a laboratory experiment using matrix acidizing technique were carried out. The successful of this technique depends upon several pa...
