Abstract
This field X well production has indeed occurred in the sand and this well has been carried out with waterflooding with injection water that is currently available. In this study of sand problems it is intended to find out the cause of the problem of sandiness in terms of laboratory analysis of formation rock samples and injection fluid. Laboratory analysis consists of fluid characterization, rock characterization that is specifically assigned to rock minerals (SEM and XRD), and fluid injection compatibility tests with rocks, then a sand retention test is performed. After the addition of clay stabilizer in injection water, Zone A, Zone B and Zone C have increased apparent permeability to reach an interval of 500% -1000% mD. The use of Zetpass cannot be used in zone A because there is a lot of clay and the grain is very fine, but it can be used in zones B and C. Fluid interactions with rock minerals and chemical interactions will reduce the cementation of rocks so that they can trigger the occurrence of sand. Clay stabilizer is important to note in wells that have done waterflooding. ZetPas solution is able to become sand control but has limitations.
