Apparent Wireline Operations being conducted in the Hickory-1 Discovery well
The below photo was taken by and share with this group and Posted by u/skidooseadoo83 88 energy Ltd well pad 3/17. Again, many thanks for sharing
[Thank you Little_Can9156 u/Little_Can9156 for pointing out the wireline operations.}
It is apparent by the equipment in use that wireline operations were, at the time of the photo, being conducted in the well.

Discussion.
Previous photos indicated that the drill pipe was no longer in the rig's derrick. It was assumed that the drill pipe had been run back into the well bore. However, with the new photos and the close-up reviews, it is apparent the drill pipe was laid back down, as singles, and placed back inside the rig's enclosure. This is because Wireline Tools, either logging or perforating, cannot be in the 7-inch casing at the same time as the drill pipe. That being said, the following is observed.
The lubricator or riser section is used to allow the full wireline tool string to be raised above the wellhead before and after the operations. The length of lubricator required is proportionate to the length of the wireline tool string.

The rise length can accommodate 30 foot length perforating guns. If the interval is 90 feet, then three runs would be required.

Summary: Step-By-Step
Wireline operations were conducted in the Hickory-1 Discovery well on 3/17/2024. Exactly what type of wireline operations is not known, but the operation required High Pressure Equipment which suggest Perforating the reservoirs.
A perforation in the context of oil wells refers to a hole punched in the casing or liner of an oil well to connect it to the reservoir. It creates a channel between the pay zone and the wellbore to cause oil and gas to flow to the wellbore easily.
Hydraulic Fracturing operations can and must following perforating operations. After fracturing, the well will be flowed back and flow testing commences.
