Elsevier's Oilfield dictionary : in five languages, english-american, french, spanish, dutch and german

"(...) In cases where a suitable translation is not popular or is not available, the english word has been repeated if it is accepted as the current standard. Different terms may be used for a single english word in spanish-speaking countries. It was considered beyond the scope of this dictionary to include all the possible alternatives used in the countries where spanish is spoken".
