Abstract On April 2017, the well Cupiagua H42 located in Colombia was suspended due to lifting capacity which were caused by low gas-liquid ratios (GLR) despite a 5" × 4-1/2" velocity string had been hanged below Down Hole Safety Valve (Insert Valve) after original completion was run in order to improve the lifting capacity. Others technical approaches for well recovery and recoverable volumes were evaluated, for example Coiled Tubing gas lift technology and conversion to a gas injector. However, economic evaluations of the different approaches considered, indicated only marginal results and low probability of operational success due to a fish at the top of the 4-1/2" OD liner. Taking all these fact into consideration, the decision was to abandon the well in accordance with Colombian Governmental regulations. The Achieving of this requirement would be difficult due to the 3.25-in. restriction in the well, and the necessity of isolation inside the 7-in. Production Liner.
