New Prospects Discovery by Geological Support of Development Drilling

In the current paper a successful example of solving a goal which took place over development drill support process is presented. The work was carried out using 3D seismic data reinterpretation (seismic facies analysis) and by operative involving of 8 drilled wells information into the model. Onshore oilfield X is located in Western Siberian region, productive formation is related to Upper Jurassic sistem and characterized by numerous uncertainties, including wide tuning zone, reservoir properties distribution. Data integration and effective drill support process allows to reduce uncertainty in J1 fm area of distribution, discover new perspective area to the following drilling. Additional oil reserves and high permeability of the formation are greatly increased drilling profitability.
