Abstract
A drill assembly has a stinger with downward oriented cups including an upper cup and a lower cup. The cups create a loss zone therebetween in a downhole environment. The downhole environment can be a shaft of a well. The loss zone can be filled with cement to plug the shaft. The downward oriented cups isolate the loss zone from the shaft and minimize the hydrostatic pressure above the upper cup.
