Abstract

The CP-52 and CP-54 wells are located on the Tambun structure of Bekasi Regency of West Java Province with the target formation being Baturaja. The pressure build up analysis is carried out for monitoring activities to obtain reservoir and boundary, innitial pressure (Pi), permeability (k), skin (s), ΔP skin, average pressure (Pavg), and flow efficiency information. Tests performed on both wells are pressure build up test (PBU) and to analyze the method of Horner approach pseudo pressure and P2 either manually or with the help of software v.ex.2 v2.02 as validation.

Abstract

In this paper, a numerical study was conducted to investigate the effect of spatial heterogeneity of multiple porosity fields on oil recovery, residual oil saturation,   polymer retained, and polymer adsorption. The generated porosity fields were applied to UTCHEM for simulating polymer and water flooding in heterogeneous two-layered porous media. From the analysis, the increase of reservoir heterogeneity resulted in higher polymer retention and lower polymer adsorption. In general, polymer flooding results in more balance residual oil saturation in the upper and lower layer than water flooding. This indicated that the vertical sweep efficiency of polymer flooding was better than water flooding. Residual oil saturation ratio between layers after water or polymer flooding was about equal along with the increase of reservoir heterogeneity. Spatial heterogeneity of multiple porosity fields had only a small effect on recovery factor. The variation of the recovery factor of polymer and water flooding due to the reservoir heterogeneity was under 1%.
