Oilex Confirms Miocene Oil Flow in Cambay Field

Oilex noted that the appraisal program initiated recently in the western portion of the Cambay field has confirmed the oil potential of the shallower Miocene section through the results of the recompletion of an old well, Cambay - 64 and the initial results from Cambay - 74, which is currently drilling.


Re-entry of existing well Cambay-64 and testing from a 2 meter interval of perforations in the Miocene Basal Sand (MBS) has yielded a flow of approximately 250 barrels per day of oil at a flowing tubing pressure of 660

The well has been choked back to prevent sand production as some wells completed in the MBS elsewhere in the area have produced sand. No sand has been produced from Cambay-64 and the choke is gradually being opened as testing continues.

Preliminary field analysis of the crude oil indicates an high quality light crude with a gravity of 38 degrees API.

The crude is being trucked to a nearby refinery and sold along with the other produced crude from Cambay Field.

While the MBS has been a secondary objective in the appraisal drilling campaign, no oil resources were assigned to this target in Cambay Field volumetrics. Oilex anticipates that the commercial impact of this additional resource could be significant and will be addressed once Cambay-74 data are available.

The MBS is commonly an excellent reservoir and at a depth in this area of approximately 1400 meters, offers the potential for low cost development and early production from the Miocene.


Cambay-74 has reached a TD of 1603m in the 12 1/4' hole section. The well has been logged and 9 5/8' casing will be run.

The well is located approximately 400 meters to the north-west of Cambay-64 and has intersected a thicker MBS in the same reservoir compartment.

Wireline logs from Cambay-74 indicate the presence of hydrocarbons in the MBS, as well as additional hydrocarbon bearing zones in shallower Miocene sands.

Further evaluation of the Miocene interval including testing will be carried out in Cambay-74.
