JetString Well Unloading

Underbalanced Well Unloading

Well unloading operations using coiled tubing and nitrogen can be costly. In low bottomhole pressure wells, nitrogen lift performance can be quite poor, often resulting in long and expensive workover operations with incomplete load fluid recovery. 

JetString is a simple innovation used for rapid well unloading operations and is based on Jet Lift Systems’ advanced jet pump technology.  The JetString assembly is coiled tubing deployed, and powered with a pressure truck – pumping just water.  JetString lift rates are application specific, but often range from 150 to 300 m3/D – all the while drawing the BHP down lower and lower towards pump-off.
