During flow a condensate gas well, downstream pressure dropped many times. The reason was partially plug which was occurred in choke manifold adjustable path due to producing abnormal cutting, junk and debris. Produced debris led to other problems such as malfunctioning in the Christmas tree and subsurface safety valve. The goal of this article is to present the procedure of lubricating and bleed-off method to control a gas well during production when there are malfunctioning in x-mas tree valves and subsurface safety valve. In this paper, other operations such as the Christmas tree substitution with a new one, installing and retrieving blanking plug, and mending subsurface safety valve malfunction are explained stepwise.
