Question

5. A well is being drilled at 7,500 ft. A sudden increase in pit volume is observed. In the 3 minutes it takes to notice the increase and close the

BOP's, 18 barrels of mud are "gained". The original mud density was 10.4Ibm/gal and circulation was 370 gpm. After stabilization, a drill pipe pressure of 200 psig and a casing pressure of 300 psig were observed. This is a11" hole with 19.5#, 5" OD drill pipe and 9x4" drill collars (300ft). Calculate the kick density.
