Question:
Which ONE of the following is used to support the packer against the casing while expanding the rubber sealing element?
Which ONE of the following is used to support the packer against the casing while expanding the rubber sealing element?
Show Hint
Side pocket mandrels provide critical support during packer expansion to ensure the rubber sealing element is correctly deployed in the wellbore.
Updated On: Dec 2, 2025
- Blast joints
- Slips
- Landing nipples
- Side pocket mandrels

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understand the packer function.
A packer is a mechanical device used in the oil and gas industry to create a seal in the wellbore. To effectively expand the rubber sealing element against the casing, it requires proper support.
Step 2: Evaluate the options.
- Option (A) Blast joints: These are used in explosion-related operations, not for supporting the packer during sealing element expansion.
- Option (B) Slips: Slips are used for gripping and holding tubulars but do not support the packer’s sealing element.
- Option (C) Landing nipples: These are related to tool landing in the wellbore, not specifically for supporting the packer.
- Option (D) Side pocket mandrels: These are specifically designed to support the packer during the expansion of the rubber sealing element. They are used to anchor the packer securely against the casing.
Thus, the correct answer is (D).

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).

- The hydrostatic pressure gradient in a vertical well drilled in a relaxed depositional basin is \(0.452 \, psi/ft\). Assume that the gradient of effective horizontal stress with depth is constant in the drilling zone and has a value of \(9.96 \times 10^{-2} \, psi/ft\). The casing shoe is at \(4000 \, ft\) depth. While drilling the bore hole below the casing shoe with \(10 \, ppg\) mud, the maximum allowed standpipe pressure is \(________\) psi (rounded off to one decimal place). (Note: 1 ppg mud is equivalent to \(0.052 \, psi/ft\)).

- A drilling fluid with time-dependent rheology is used for rotary drilling of a reservoir. The shear stress \(\tau\) satisfies: \[ \tau + \frac{\mu_0}{\alpha} \frac{d\tau}{dt} = \mu_0 \dot{\gamma} \] where \(\mu_0\) and \(\alpha\) are constants. If the rotation of the drill pipe is stopped at \(t=0\), then the relaxation behavior of \(\tau\) with time is:

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.
