...) and without the reservoir (solid line) from a sin- gle 100 m dipole whose center is located at x=-6.5 km. There is a slight increase in the field around the position x=0 km when the reservoir is present. This 20% difference is shown by the ratio of the field with the reservoir to the field without...
