TORONTO, May 12 /CNW/ - Aurora Oil & Gas Limited ("Aurora") is pleased to provide the following update on operations and production at the Longhorn, Ipanema and Excelsior Areas of Mutual Interest ("AMI") within the Sugarkane Gas & Condensate Field, Texas.

Across Aurora's gross acreage position of 74,800 acres there are presently 4 drilling rigs and 2 full time fracture stimulation crews operating, with a temporary 3rd stimulation crew carrying out 'HiWay' stimulations on 4 wells. The operator is ahead of target to complete the planned 60 well drilling program in 2011.

Production Data

The Foster #1H well has now been on production for a period of 30 days with results as outlined below:-

  AMI Working
Total Gas
Average Daily
Equivalent Oil
Rate (boe/d)*
Foster #1H Ipanema 34.3% 52.9 12,852 758

*The equivalent barrels per day production rate has been calculated on a simple 6:1 ratio in compliance with Canadian securities laws under National Instrument 51 - 101.

There are a number of wells that commenced production since the last ASX update within the Longhorn, Ipanema and Excelsior AMIs and Aurora will provide 30 day and 60 day average production rates for those wells when available.

Excelsior Production Facilities
Good progress is being made on the installation of the first centralized processing facility in the field. This facility is located in the Excelsior AMI and will lead to significant savings in well costs and reductions in operating costs.  Other similar installations will be installed in due course across Aurora's four Sugarkane AMIs.

Cautionary Statements

The Company may present petroleum and natural gas production and reserve volumes in barrel of oil equivalent ("boe") amounts. For purposes of computing such units, a conversion rate of 6,000 cubic feet of natural gas to one barrel of oil equivalent (6:1) is used. The conversion ratio of 6:1 is based on an energy equivalency conversion method which is primarily applicable at the burner tip and does not represent value equivalence at the wellhead. Readers are cautioned that boe figures may be misleading, particularly if used in isolation.

Statements in this press release regarding which reflect management's expectations relating to, among other things, target dates, Aurora's expected drilling program and the ability to fund development are forward-looking statements, and can generally be identified by words such as "will", "expects", "intends", "believes", "estimates", "anticipates" or similar expressions. In addition, any statements that refer to expectations, projections or other characterizations of future events or circumstances are forward-looking statements.
