John -

Did you intend to attach a photo or description of the company name and what you saw? If so, please do so and I'll give you my best idea

The name of the company is Torqued up. As Fang has said they are a coiled tubing co. A tanker truck of nitrogen also showed up. Is this indicative of pressure issues?

John/ Fang -

If the CT equipment is accompanied by an N2 tank and converter, this suggests to me that they will run the CT into the well and gas lift it in with the N2.

CT is relatively weak and soft carbon steel. It is not possible to torque up CT by itself, but tools can be attached to the end of the CT that can generate torque

It doesn't suggest pressure problems to me, maybe it is one lazy lateral or one who cannot supply enough gas to maintain natural vertical flow or that there are still a lot of frac solids to lift (excess proppant, etc).

 

CT is also often used to clean debris from laterals or vertical sections to facilitate flow, or to drill out frac sleeves, etc. CT is very versatile, but also with numerous disadvantages. Careful planning is a must. I've had some high highs and some very deep lows with CT, and have spent many hours in the control cabin supervising jobs

Thanks guys. Is this a common issue? Does it mean bad things for future laterals at the sight?

One cannot infer much about other laterals on a given well pad based on one well having to be lifted to induce flow.

Most multi lateral wells that I worked on or helped to drill/complete had one strong and one less strong leteral. The strong one would feed gas at higher pressure, which would keep liquids clear and allow flow from the other laterals. The wells like this that I worked on were in the Middle East and were drilled open hole (barefoot) without fracing. Cuttings and other debris would accumulate in the lateral and would occasionally have to be cleaned out.

If the operator in your area were truly concerned about pressure, they may intervene in the well and record some downhole information to assist with the analysis.

 

Again, I would not condemn the entire well without having a lot more information at hand. 

 

Good luck,
