... (bottom) well completion isolated by a packer from the top completion. The bottom completion diverts water from the top completion so gas production is maximized and water-free. The study analyzed simulated performance of DWS wells for different values of well design parameters (the top and bottom...

..., and analyze simulation runs and to build accompanying tubing performance models. In this paper, a nodal analysis approach for dual completed wells is proposed to evaluate natural flow rate. The approach identifies the operational range of top and bottom rates with water coning at the top completion and oil...

... Abstract A new method and software have been developed to identify promising reservoir candidates for production improvement using DWS technology. DWS employs dual completion in wells affected by excessive water problem. The bottom completion drains the water and keeps the top completion open...

DWS wells are different from the DGWS wells by inclusion of a second bottom completion that controls water outside the well and prevents commingled inflow of gas and water to the top completion. The wells have been...
