Index Oil and Gas, Inc. says that initial test results for the Ducroz 1 well ("Ducroz") in the Cowtrap prospect located in Brazoria County, Texas, achieved test flow rates of approximately 4 million cubic feet of gas per day flowing from dual completions in two Miocene sands using a 10/64ths inch choke.

These test flow rates were achieved following the decision to plug the original directional hole and drill a vertical hole which reached a TVD of 6450 ft.

It is anticipated that Ducroz will start production and begin flowing into the local pipeline grid during the first calendar quarter 2008.

Ducroz (defined as a production well) is the fifth well drilled from the Company's portfolio in the fiscal year ending March 31, 2008. Index has a 7.5% working interest and a 5.25% net revenue interest.

Lyndon West, CEO of Index, stated, "Following our positive results for the Cason and Outlar wells, the success of the Ducroz well continues to demonstrate the delivery of the Index business plan. Along with successes at Cason and Outlar, Ducroz adds incremental volumes and production potential which have been key objectives for our 2008 portfolio. Further operational news will be released as it becomes available."
