Petronor Hiztegia petrolio- eta gas-sektoreari dagokion hiztegi espezializatua da. Sektore horretan, etengabe sortzen dira termino berriak, eta, gure eguneroko lanean, argi ikusi dugu haiek jaso eta aztertzeko beharra. Horregatik, Petronorrek Elhuyarreko Hizkuntza eta Teknologia unitateko terminologia-adituen aholkularitzapean, hiztegi hau sortu du. Gure lanean erabiltzen ditugun terminoak lau hizkuntzatan jaso, eta gizartearen esku jarri ditugu.

So, properly managing languages and setting up a language strategy at work is a key aspect for competitiveness, as it allows us to display greater proximity to the client. Bearing this aim in mind, there is no doubt that managing the terminology of our sector and our companies has been a very important step.

At the same time, this dictionary aims to help in the normalization of Basque language and for this, with other languages, we have brought the terminology in Basque of this sector.

This dictionary seeks to gather the multilingual terminology of the oil and gas sector and thus meet the terminology needs of companies, professionals and experts in this field.

We have produced the Petrnor Dictionary to be able to effectively meet the communication needs of oil and gas sector users. The dictionary has started off with 1,500 items used in the sector in 4 languages (English, Basque, Spanish and French). 300 of them has definitions. The items have been classified into the different areas of oil and gas.

In order to improve relations with clients and internal communication in Petronor, we are aiming to build this dictionary. website that includes not only terminology, which will be of tremendous use to us in our daily work.
