oa Experimental Design Based History Matching of Reservoir Simulation Models for Champion Field

The Champion Field is located 40 km offshore Brunei, northern Borneo. It is a mature field with over 250 producing<br>wells, oil production commenced in 1972, and the current recovery factor remains below 20%. The field comprises<br>about 20 NE-SW oriented elongate fault blocks separated by East hading extensional faults, and there are about 100<br>individual reservoir units, giving a total of more than 500 hydrocarbon bearing compartments. To date, 37 water<br>injectors have to varying degrees stemmed a part of the production decline. As such, redevelopment of this giant<br>field calls for a large investment in water injection. How do you decide to make such a large investment when faced<br>with such a complex field, where credible production and injection data is limited?
