Sažetak
Sand control and production of hydrocarbons from weakly consolidated sandstones in the world is a growing challenge. Methods of sand control is directly dependent on the geological settings of hydrocarbon reservoirs. The paper describes the sand management of the oil field "B" which is located in the western part of the Sava Depression (Croatia). The paper analyzed the sand management (control) of subsurface system on the example of the well J-160 (weakly consolidated sandstones reservoir "N") and the surface system on the example of the central gathering station of field "B". The result of sand management on the analyzed well is the production of 10 m3/day oil, with an interval between workovers of 38 months. That proved the choice of 20/40 mesh (0.43-0.84 mm) sand granulation for the modified gravel pack as appropriate and applicable in the wider geological area of field “B”.
