What oil analysts would like to know about the Khurais oil field in Saudi Arabia is can it deliver. This is the Saudis big effort to sustain and increase oil production as other fields are aging and declining. The Saudis would like to see it add 1.2 million barrels a day to its current production of 11 million barrels a day. no date is set for when this oil field will come on stream and how much of the 1.2 million barrels a day will become reality. The Khurais field has been sitting there for many years while the Saudis tapped the Ghawar field just 60 miles away because of the complexity of the Ghawar field which situated deep within the rocky layers of the earth and dunes. Its been described as a hard sponge compared to the wet sponge that Ghawar is. The natural pressure is not enough to bring the oil up so natural gas or filtered salt water would have to be used. As natural gas is needed for soaring power generation needs filtered salt water will be brought from over 120 miles away from the Persian Gulf through pipes to Khurais and more than 100 injection wells have to be drilled so that 2.3 million barrels a day can be pumped down in a manner that would push the oil up but not kill an oil wellby going through a rocky fissure. All this has to understood through geologic mapping of 2700 square miles down to the microdetail for an area the size of Connecticut so that nothing goes wrong. 2.8 million 3-dimensional images of underground strata to trace any fractures in the rock that might cause trouble and building of models to simulate how the oil field may respond to water injection. The production would have to be monitored from Dhawan where the central monitoring facilites are for Aramco. Aramco the Saudi Oil company brought in for oil field services Foster Wheeler as project manager, Halliburton for drilling wells, Eni SpA's Saipem unit for water injection work, in the plan developed in 2005 with estimated cost of $6 billion. Halliburton is drilling more than 300 wells that go over a mile deep and then branch out horizontally, and 125 water injection wells. Nansen Saleri who heade reservoir management for Aramco and headed the Khurais revitalization effort is now running his own firm in Houston. He described it - the trick is to understand Khurais down to the smallest detail. This is a picture of the complexity and the resulting uncertainties of Khurais. A former head of Aramco oil exploration Mr. Husseini who retired 5 years ago says its quite possible that Aramco may achieve its target of 1.2 million barrels a day but isn't sure that production can be sustained at this level and what it might cost. Khuransiyah project was expected to generate half million barrels a day by 2007 en but is a year off schedule and many projects are running late from a shortage of steel and manpower. It used to cost $4000 to add one barrel of capacity through the 1990's now its estimated by experts to cost closer to $16,000 for a barrel added. So when will Khurais come on stream? And will the even more difficult Manifa field in the Persian Gulf come onstream? Its not certain. meantime oil reached 119 dollars a barrel. But analysts will be sure to watch this one and the new fields in Brazilian offshore waters to bring prices down just as conservation kicks in and global demand slips a bit from the super heated growth of the last few years especially from Asia.
