The Al Shaheen Oil Field is a production oil and gas field off the north east coast of Qatar in the Persian Gulf, 80 kilometres (50 mi) north of Doha. The oil field lies above the North Gas Field, one of the largest gas fields in the world. The field has been operated by Maersk Oil Qatar AS of Denmark until July 2017 under a production sharing agreement with Qatar Petroleum, on behalf of the state of Qatar. As of June 2016, Qatar Petroleum and the French major Total S.A. established a new company known as "North Oil Company (Qatar)". The new company is 70% owned by Qatar Petroleum and 30% by Total. North Oil Company took over field operations on 14 July 2017.

North Oil Company has been implementing a phased approach to the development of the Al-Shaheen oil field since assuming operatorship in 2017. A total of 17 wells were drilled under the phase one development plan as of 2018, while the phase two development, called the Gallaf project, includes the installation of eight new wellhead platforms (WHPs) at the field in three batches. In batch-1, three new WHPs have been installed and connected to the existing platforms, while the remaining two batches will involve two and three new WHPs respectively.
