Oilex said the tests would be run at progressively shallower intervals to determine reservoir pressure and fluid composition after logs run during the past week showed hydrocarbons.

The first test would be at the level of the basal sand overlying the Deccan basement, the secondary exploration objective in the well.

According to Oilex, a 6m interval between 1966-1972m that gave the best indication of hydrocarbons from logs over the zone would be tested.

The EP III and EP IV primary objectives will follow and be tested over a gross interval of 34m between 1764-1798m.

These zones had good gas shows while drilling, Oilex said.

The Basal Miocene and Oligocene OS II secondary objectives will also be tested. Logs from these objectives indicated about 9m of gas-bearing pay between 1505-1545m.

If the well tests successful for oil, it will be completed for near-term production; if it tests successful for gas, the well will be suspended for production at a later date, 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%.
