Shell

 is a Dutch-British oil and gas producer headquarted in the Netherlands and incorporated in the United Kingdom. Their famous "sea shell" logo has appeared in quite a few episodes of the Pelle Politibil TV series, usually in the background or in the form of a gas station.

Får En Venn ("Gets A Friend")
A Shell station appears briefly in the background as Rikhard takes Pelle out for a test drive.

På Besøk I Barnehagen ("Visit To Kindergarten")
What appears to be the same Shell station seen in the previous episode appears briefly during the dream Rikhard has, with a Statoil station across the street from it.

Festen ("Feast")
The same Shell station and a Shell pickup are seen at the very beginning as the camera pans across the city of Bodø and then stops at Sally's garage, where she and Pelle slept during the last episode. The same Statoil station from the previous episode can be seen across the street from the Shell station.

Tyvjakta ("Thief Hunting")
A few Shell barrels can be seen near the garage door that Rikhard opens when he and Pelle go out on patrol.

Den Store Bølgen ("The Big Wave")
A Shell barrel can be seen beside Rikhard at the construction site, then a Shell station can be seen in the background as the police master and all the other Norwegian Police Service officers are clearing out the old station and getting ready to move to the new one. This station appears to be the same one from Får En Venn, På Besøk I Barnehagen and Festen.

Skurkene Kommer ("The Villains Are Coming")
A Shell billboard can be seen right at the start of the episode in the background as the police master tells Rikhard what he wants him to do. Much like the Statoil gas station across from the Shell one in previous episodes (minus Tyvjakta) a Statoil sign can be seen to the right of the Shell billboard. Right after Pelle and Rikhard leave Sally and Janne, they stop at a Shell station, where Rikhard gets Pelle fueled up. While there, Pelle spots some tires on a rack for sale and demands that Rikhard buy them for him. After he does and Pelle is fitted with them Rikhard and Pelle head off for UP-police patrol duty.

Arrestasjonen/Pelle's Bursdag ("The Arrest/Pelle's Birthday")
A Shell barrel can be seen behind and in between Pelle and Sally as they're resting in the garage at the end of the episode.
