Since 1980, etasa has been dedicated to the development, manufacturing and marketing of perforating equipment for the use in oil, gas and water well applications. To date, forty different types of shaped charges are actually being manufactured by etasa, including our own designs and the development of -third party- designed charges. Etasa supplies to the main perforating companies in the industry. ETASA's products were designed to be compatible with our own hardware designs and the hardware provided by other companies.
