Section I
In its main section, which is born in San José de Saramuro, it advances parallel to the Marañón River, which it crosses twice. On its way, it passes through dense, wooded and swampy areas, crosses the high jungle, ascends through the Andes at 2,390 meters above sea level, and then descends, crosses the Sechura desert, and finally reaches the Bayóvar Terminal.
Section II
From Station 5, which is the confluence point with the North Branch Pipeline (ORN), the ONP continues in a southwesterly direction, to Station 6, in Kuzu Grande, Manseriche district, Alto Amazonas province. It continues parallel to the highway, which goes from the town of Mesones Muro to Bagua, in the Amazon region, where Station 7 is located. In a southwesterly direction, it reaches Station 8, in the vicinity of the Playa Azul town, Pucará district, Jaén province, Cajamarca region. At that point, the ONP changes to a northwesterly direction, to Station 9, which is the last pumping station, and from there it begins its ascent towards the Andes mountain range, which it crosses at Paso de Porculla, at a height 2,390 meters above sea level. In this place begins its descent towards the Bayóvar Terminal, crossing the Sechura desert, in the Piura region.
North Branch
The North Branch made it feasible to transport the crude oil that is extracted from the oil fields of lot 192 (formerly lot 1AB). It begins its journey at Andoas Station and continues in a southwest direction, crossing the Pastaza, Huazaga and Huituyacu rivers, until the Morona river crossing. The pumping station of the same name is located there. Always in a southwesterly direction, it crosses the Marañón River and continues, through flat and dry terrain, until the crossing of the Saramiriza River, reaching Station 5 of the ONP on its final route.
North Branch
Since its inception, ONP has transported 971 million barrels of crude oil.
