Abstract
The invention provides for an improved method of removing debris from a producing oil, gas, or commercial water well without the necessity of using a service rig or retraction of the tubing string. In accordance with this method there is provided a side entry sub that is situated in the well casing string. The side entry sub has an access port with a hollow feed passageway permitting the introduction of coiled tubing into the main flow passage. The coiled tubing is passed down the main flow passage adjacent to the tubing string to the desired depth. Fluids are then introduced into the well through the coiled tubing. The fluids mix with the debris and the mixture is forced to flow out of the well using the tubing string or the main flow passage of the production casing. This flow of liquefied debris facilitates effective extraction of the debris from the well without the need of a servicing rig for production tubing retraction and intervention with specialized cleanout tools.
