Abstract

Analyzed chemical and occurrence state of the formation water Risha Gas field based on geological features of reservoirs. It is necessary to determine the source of water, and depending on that to look for the proper solutions, either changing production strings, because of corrosion effect on the tubing, pumps or surface equipment. We have excluded most of the water samples analysis from the evaluation because of their variability in pH values and the wide difference between cations and anions values. Well logging tools interpretation for Risha gas wells show that the gas producing zone is at 2600 m where the formation water below 3200 m. The stratigraphic section between 2600 and 3200 m, the interval has no formation water. Interpretation results of water analyses associated with gas production after ten years of production by Stiff diagram shows that their water type is magnesium chloride and calcium chloride type, where their water patterns are more or less similar to the water pattern of (Campanian - Santonian formation) of water wells.
