which may cause corrosion of tubular, fine migration an

accelerate well abandonment. Every year more than $40 billion

is spent dealing with unwanted water, so a treatment should be

applied in order to reduce high water production. Many papers

investigated and focused their researches on how to reduce

water cut percentage. Mechanical and chemical treatments are

suggested, chemical treatment represented in polymer-gel with

cross linker solution proved an optimistic results. Gel can solve

many types of water production problems rather than other

chemical orothermechanical treatments. In thisproject amodel

constructed to determine applicability of gels in reducing water

permeability. The model included equations predicted using

statistic software (SPSS) that determine Frrw (Water residual

resistance factor) and Frro (Oil residual resistance factor) by

inserting polymer concentration then determine the optimum

concentration which gives the most desired results. A real field

data obtained from Z field (well X, well Y, and Well Z) and gel

applicability in permeability reduction had been tested, then

an optimistic result obtained. According to this study there is a

great chance to apply polymer- gel as water shut-off technique.

For future work a core flooding study must be constructed

to obtain more set of data and improve equations accuracy.
