Frequently asked questions
For anything specific to your well, call dispatch.
We’ve got tubing stuck downhole. What are our options?
That depends on what’s holding it. Recovery options may include jarring, cutting, milling, or fishing. The first step is reviewing the well conditions, tubing specifications, and what has already been attempted. Dan’s can help evaluate the situation and identify suitable recovery equipment.
See Fishing Services.
We’ve parted the tubing. What’s the best way to recover it?
It depends on the condition of the fish top, available clearance, and well configuration. An overshot may be suitable for external engagement, while a spear may be an option for internal engagement. Damaged or irregular fish tops may require additional preparation before recovery.
See Fishing Services.
Our packer won’t release. What can we do?
Start by confirming the packer model, release mechanism, and previous release attempts. Depending on the situation, recovery may involve additional manipulation, cutting, milling, or fishing. Dan’s can help identify equipment options based on the specific packer and well conditions.
See Fishing Services and Retrievable Packers.
What information should we have ready when planning an abandonment?
A current wellbore schematic, casing and tubing specifications, existing downhole equipment, pressure and temperature conditions, known restrictions, and the proposed abandonment program are useful starting points. Dan’s can use this information to help identify the required equipment.
See Well Abandonments.
What if the casing won’t move, even with additional pulling force?
Additional force isn’t always the answer. The cause of the restriction needs to be understood before proceeding. Depending on the conditions, the recovery plan may require changes to the pulling arrangement, cutting, or other intervention methods. Dan’s can help identify suitable equipment options.
Can we mill out an obstruction without pulling the production tubing?
Potentially. Thru tubing motors and mills can be used for certain obstruction-removal applications. The available clearance, obstruction material, well geometry, and operating conditions determine whether the work is feasible.
What if our coiled tubing bottom hole assembly gets stuck?
Recovery depends on the assembly configuration, the cause of sticking, and the available release mechanisms. Jars, disconnects, and fishing equipment may form part of the recovery plan. Dan’s can assist with identifying compatible downhole equipment.
See Thru Tubing & Drillout and Fishing Services.
We’re planning a difficult fishing job. Can Dan’s help us work through the equipment requirements before mobilizing?
Yes. Early discussions about the fish, well configuration, restrictions, and anticipated loads can help identify suitable tools and potential equipment limitations. Dan’s can assist with equipment planning so the operator can finalize the recovery program.
See Fishing Services.
