Question 4589 Deck General
70% to passWhile drilling ahead with 60 foot draft, the DEEP DRILLER encounters lost circulation and loses 460 barrels of 16 pounds per gallon mud to the hole. What is the resulting draft if no additional ballast is taken on?
A
57 feet
B
58 feet
C
59 feet
D
60 feet
AI Explanation
The correct answer is C) 59 feet. When the DEEP DRILLER loses 460 barrels of 16 pounds per gallon mud, it results in a loss of weight, which in turn causes the draft to decrease. Assuming no additional ballast is taken on, the resulting draft would be 59 feet. The other options are incorrect because: A) 57 feet - This would represent a draft that is too low given the weight loss. B) 58 feet - This would also be too low for the given weight loss. D) 60 feet - This would be the original draft, which is not the correct answer since the weight loss would cause the draft to decrease.
