A lost circulation alam was sounded by the well monitoring equipment just before the cement job, and the drillers notice that the hook load slowly increases. A total of 15000 lbm of hook load was gained before the hook load again stabilized. The well contained 12 lbm/gal mud, and the casing string consisted of 9000 ft of Grade C-90 casing with the properties tabulated below. The open hole having a diameter of 12.25-in. Steel has a density of 65.5 lbm/gal. Length, Weight, Body yield strength, klbf Grade OD.
