Abstract
A bottom hole assembly used for making a window in a tubular is modified to reduce tool joint stress in a connection above the topmost watermelon mill. A protrusion is located between the topmost watermelon mill and the next threaded joint uphole. Preferably, the protrusion height is not greater than the outside dimension of the largest watermelon mill. Preferably, the protrusion is located below the upset area in the tubular where the threaded joint is made up and about ⅓ the distance downhole from the threads to the next adjacent watermelon mill.
