Step 1: The conductor is the outer casing of a well, and it is used to protect the well from external pressures.
Step 2: The riser transports the fluids between the seabed and the platform.
Step 3: The conductor and riser have different functions. The conductor is related to well casing, while the riser is for fluid transportation.
Step 4: Therefore, the statement in option (C) is incorrect.
A vertical well is drilled up to a depth of 4000 ft. Further drilling starts with 10 ppg of fresh mud and \(50000 \, lbf\) weight on bit (WOB). An equivalent circulation density (ECD) of \(10.75 \, ppg\) was recorded. The total circulation pressure loss is estimated to be 110 psi. The still density is \(65.5 \, ppg\). The decrease in hook load is ________ lbf (rounded off to one decimal place). (Note: 1 ppg mud is equivalent to \(0.052 \, psi/ft\)).
A horizontal well is planned with two radial sections to land the target at an angle of \(90^\circ\). The total vertical depth (TVD) between the surface and the target is \(8000 \, ft\). The buildup rate is \(6^\circ\) per 100 ft in the first section and \(9^\circ\) per 100 ft in the second section. The total angle built by the second section is \(30^\circ\). The distance of the first kickoff point from the surface is _______ ft (rounded off to one decimal place).
Identify the option that has the most appropriate sequence such that a coherent paragraph is formed:
Statement:
P. At once, without thinking much, people rushed towards the city in hordes with the sole aim of grabbing as much gold as they could.
Q. However, little did they realize about the impending hardships they would have to face on their way to the city: miles of mud, unfriendly forests, hungry beasts, and inimical local lords—all of which would reduce their chances of getting gold to almost zero.
R. All of them thought that easily they could lay their hands on gold and become wealthy overnight.
S. About a hundred years ago, the news that gold had been discovered in Kolar spread like wildfire and the whole State was in raptures.
