Oilex said the Basal Miocene and Oligocene OS 11 reservoirs were intersected at 1505m and 1545m.
Once the interpretation of the log and pressure data has been finalised these two zones may be tested later to confirm pressure data and gas-condensate flow potential, Oilex said.
The Cambay-19Z well is testing the Eocene EP III and IV reservoirs on the Cambay Western High area where hydrocarbons have been identified in adjacent wells.
After evaluating Eocene EP III and IV the well will be deepened to explore the fractured Deccan Basalt objective and overlying potential reservoir horizons, Oilex said.
As operator, Oilex holds 30% of the Cambay production-sharing contract, Oilex NL Holdings India has 15%, and Gujarat State Petroleum Corporation has 55%.
