Coiled tubing12 Jul 2025 09:11
Taking a leaf out of ChatGPT’s (formerly known as Bubbles) book. Only I am copy pasting instead of trying to make it sound like I am an industry expert. What I do know is that the below will be implemented by September. Not sure what to expect but ANGs will share more details soon. It can be significant though, have been reading a few case studies and 50-100% increases have been achieved. Logic says we will be at the upper end of that.
Overview
Coiled tubing can be a valuable tool for mitigating liquid loading in gas wells. By running coiled tubing (often as a "velocity string") inside the existing production tubing or casing, the reduced annular space increases gas velocity, which helps lift liquids to the surface and prevent them from accumulating and potentially killing the well.
Here's a more detailed explanation:
Reduced Annular Space:
Coiled tubing, when inserted into a well, creates a smaller space for the gas and liquid to flow through compared to the original tubing or casing.
Increased Velocity:
This smaller space forces the gas to flow at a higher velocity. This increased velocity is crucial for carrying liquids (water, condensate, etc.) out of the wellbore along with the gas.
Liquid Loading Prevention:
Without the increased velocity, liquids can accumulate in the wellbore, potentially blocking gas flow and eventually leading to a well shutdown. Coiled tubing helps prevent this by continuously removing the liquids.
Versatile Application:
Coiled tubing can be used in various scenarios, including as a velocity string in existing production tubing or casing, or even as a conduit for other downhole tools and interventions.
Other Benefits:
Besides addressing liquid loading, coiled tubing can also be used for other well intervention tasks like well cleaning, stimulation, and logging, often without the need to kill the wel
