The state of depletion of gas reservoirs generates many challenges for production management teams that focus their efforts to operate the fields in a rational and efficient manner in order to achieve attractive recovery factors. An essential activity in terms of production management is related to the maintenance programs, particularly in the current paper, on those exploitation perimeters extended as a surfaces. This aspect, directly influences the maintenance activity in daily basis on the gas wells such us soaping and flowback programs for liquid unloading, visual inspection of wellhead integrity and pressure measurements. It has been noticed throughout the production history that the wells located on extended exploitation perimeters as surfaces, some of them being placed in isolated areas, have low productivity and do not produce at their potential. The causes identified in this regard are as follows: – The wells are liquid flooded or loaded and are not able to unload using their own energy being in an advanced stage of depletion. – There are not enough representative production data recorded to monitor the real performance and intervene in the right time, in order to improve the well productivity. The relatively large distances between the wells and the technological groups correlated with difficult access to the well location are the main arguments for the implementation of the specialized mobile teams which aims to monitor the wells performance, to ensure a safe exploitation process of the productive infrastructure, to improve the field management activity, respectively to increase the wells productivity.
