Wykorzystanie modelowania przestrzennego do wyznaczania stref pod odwierty eksploatacyjne dla PMG działających w obrębie wyeksploatowanych złóż konwencjonalnych

Exploited conventional reservoirs located in the south-eastern part of Poland, characterized by favorable petrophysical parameters, are being used for underground gas storage under appropriate technological and economic conditions, as exemplified by UGS Husow, Strachocina, Swarzow or Brzeznica. The use of subsurface modeling software for visualizing spatial reservoir parameters’ distribution within old gas fields, is associated with a significant degree of uncertainty resulting from a wide variation in time of data acquisition and factors affecting its representativeness. The article presents the concept of using modeling adapted for old, conventional gas reservoirs, assuming the selection and processing of reinterpreted gamma ray logs to create pseudo-facies classification. Visualization of its elements, along with geological and reservoir interpretation, can be used for further analysis, including decision making in the aspect of picking out predisposed zones for new wells associated with increasing UGS total storage capacity. Modeling was conducted with the use of the Baker Hughes JewelSuite™ Subsurface Modeling software.Słowa kluczowe: modelowanie 3D, Karpaty, zapadlisko przedkarpackie, podziemne magazynowanie gazu.

The use of subsurface modeling software for visualizing spatial reservoir parameters’ distribution within old gas fields is burdened with significant uncertainty related to wide range of time diversity of data acquisition and factors affecting its representativeness. The article presents the concept of using modeling adapted for old, conventional gas reservoirs, assuming the selection and processing of reinterpreted gamma ray logs to create pseudo-facies classification. Visualization of its elements, along with geological and reservoir interpretation, can be used for further analysis, including decision making in the aspect of typing perspective zones for new wells associated with increasing UGS total storage capacity.
