Is it permissible to pray Jumu'ah (Friday prayer) in oil fields hundreds of kilometers away from urban areas, and what is the ruling on one who abandons it, if it is obligatory or the opposite?

The Friday prayer is valid in oil field locations if they are prepared for residence and the workers are settled there like residents in their homelands. It then becomes obligatory upon them, and whoever intentionally leaves it, knowing of its obligation, commits a grave sin that necessitates repentance.
