Cairn Completes 2nd Successful Test Well in Western India

Cairn and Shell have completed a second successful drill stem test ('DST') on the RJ-H-1 discovery well in Block RJ-ON-90/1 onshore Rajasthan in Western India, bringing the cumulative test rate for the well to 2,020 barrels of oil per day.

The test was carried out on a sand unit perforated over a 26 mmd interval and flowed at a stabilized rate of 1,400 barrels per day of 42 degrees API oil and 150,000 standard cubic feet of gas per day on a three-quarter inch choke.

This follows the first drill stem test in fractured basement, which produced formation water and a second test in a sand which produced a stabilized flow rate of 620 barrels per day of 41 degrees API oil on a half-inch choke from a 27 mmd interval.

The well, which is located approximately 50 kilometers north of the Guda-2 oil discovery drilled in 1999, was directionally drilled to a total depth of 1,837 mmd and encountered a number of hydrocarbon bearing units below 1,400 meters, not all of which were tested.

Initial combined reserves for the two successfully tested intervals are estimated to be in the range of 20 to 40 million barrels of oil.
