The area of this study is one of the important places in Iraq, which contains many important oil fields. In this work numerical simulation of the Earth magnetic field in theAl-Zubair city- Iraq have been developed using WMM15 model. This region located at south of Iraq (lat. 30º29`N 30º 25`N), (lon. 47º 34`E 47º 36`E).The components of the geomagnetic field(total intensity(F),the east component(Y),down component(Z), horizontal intensity (H),north component (X),declination (D) and inclination (I) were found by using(WMM 15) software. Contour mapping of the above seven components were drawn by using surfer 11softawr,magnetic anomaly was found in the area confined betweenlongitudes (47.605°-- 47.612°) and latitudes (30.445° -- 30.45°), and especially in the contour lines of (F,Y,Z,D,I).
