The Khurais project is the largest onshore oil development project in Saudi Arabia, located in a remote area in the Central region, approximately 200 km from the capital, Riyadh, and 300 km from the Eastern port city of Dammam. "Two rows of oil producing wells have been drilled in the middle of the field, and two rows of power water injector wells have been drilled close to the field boundaries," according to an article, published by Saudi Aramco's Journal of Technology-Summer-2009. The article is written by Ali H. Al-Ghamdi, Fahad A. Al-Bani and Roberto H. Tello Kragjcek. It is entitled as "Delivering the largest oil increment in the world--Innovation, Solutions and Rewards". An average of 12 rigs worked simultaneously throughout the duration of the project to drill and complete the required increment wells. The Saudi Aramco Journal of Technology is published quarterly by Saudi Aramco to provide the company's scientific and engineering communities with a forum for the exchange of ideas. Articles present technical information aimed at advancing the hydrocarbon industry. The Journal of Technology is distributed without charge worldwide. --MORE
