Application of Well Test Data in Ahdeb Oilfield

The Ahdeb Oilfield in Iraq is mainly carbonate reservoir of pore type,which has the characteristics of high pore and low permeability.Due to the low amplitude of structure,oil-water difference is not obvious and the oil-water relationship of each set of reservoir is complex vertically.In order to obtain the accurate reservoir parameters,the oil-water accurate interface is established for deep understanding of reservoir characteristics.In this paper,formation parameters are analyzed the combination with well test data and production performance data,which can better understand and evaluate reservoir,monitor production performance,better evaluate well effect,it provides the basis for next improvement of production and improves the oilfield development effect and economic benefit.
