Approximative formulas for the movement of a continuously growing body of oil on the ground-water table are presented and illustrated. The approximaions are many, but the formulas are believed to produce realistic results for a major flow of crude oil from a leaking pipeline. The main objective is a simple hydraulic flow description, where also capillary forces at the rim are considered.
