Undesired water production in hydrocarbonate reservoirs can be a major problem, if the surface facility has not been designed in a way to support that. This undesired water may cause problems for process equipment in platform, sea lines and refinery. To solve and control these problems, some root cause analysis should be done in order to maintain gas production and prevent increasing of water production. To find the causes of this problem, an integrated data analysis of all probable reasons for water production in a produced gas well was performed over about one hundred wells in the field, from their first day of production till the time of the study. As water production history investigation in all of the studied wells showed that some of these wells have unnormal produced water, in order to study the cause, all probable reasons were investigated; including: considering drilling history of the wells, well cleaning reports after perforation and acidizing, perforation intervals in each well, distance from gas-water contact, quality control of cements behind Liners in the reservoir by using Cement Bonding Logs (CBL-VDL), well positions in accordance to faults and fractures, Azimuth of deviated wells in accordance to direction of maximum stress of the field. Regards to all existed evidence is concluded that unnormal water production in most of the wells have no independent relation to cement quality, distance from contact, perforation intervals; and the most effective reason in this field could be the relation between well and fault and fracture network.
Data analysis in this research has been done by following software’s: PETREL, SAPHIR, and Emerald.
