Sindh Sagar Doab

The Sindh Sagar Doab () is the tract of land in Pakistan lying between the Indus River and the Jhelum River. It is one of the five major doabs of the Punjab and forms the north western portion of the Punjab plain.
Major areas in this doab include the Kala Chitta Range, Margalla and Murti Hills, Potohar Plateau, Salt Range and the Thal Desert. Some of the major cities of this doab are Rawalpindi, Taxila, Attock, Chakwal, Jhelum, Pind Dadan Khan, Talagang, Mianwali, Bhakkar, Leiah (Layya), Muzaffargarh, Khushab and Quaidabad.
The word "doab" is of Persian origin, signifying the region between two rivers. According to Shaikh Abu'l-Fazl ibn Mubarak, the grand vizier of the Mughal emperor Akbar, and author of the "Akbarnama", the names of the doabs were decided by Akbar.
Of the Punjab doabs, the Sindh Sagar Doab is the largest in land area, but the poorest for agriculture, due to the presence of the Salt Range and the Thal desert. The Potohar plateau is the location of Pakistan's major oil fields, at Khaur, Dhuliān and Tut. A pipeline connects the oil fields to the refinery at Rāwalpindi.
