Oil Field Hideout (Japanese: かいていゆでんアジトOffshore Oil Field Hideout) is a location in Pokémon Ranger: Shadows of Almia. It is an undersea factory powered by oil, and is used by Team Dim Sun to build their nefarious Miniremo units. The player arrives here while chasing a kidnapped Wailmer and runs into Sven, who accompanies the player through the hideout. There is a library where Isaac is usually found researching, while the place from which Kincaid operates is nearby. An Electivire and a Porygon-Z can be found after completing the game. Gliscor is the boss and cannot be found anywhere else, excluding the Capture Arena.
The player first reaches the hideout on the back of a Wailord. After the mission there, the only way to access it is by flying there on a Staraptor.
Although Operation Brighton transformed the Shadow Crystal and its fragments, the Dark Shards in the hideout were not affected. As a result, remnants of Team Dim Sun joined back together under Kincaid and continued their villainy.
