TORONTO, ONTARIO--(Marketwire - June 13, 2007) - InterOil Corporation (TSX:IOL)(AMEX:IOC)(POMSoX:IOC):

Elk Prospect


Gas appraisal / oil exploration well


PPL 238, Eastern Papua Basin

145 degrees 08' 02.7587" E; 7 degrees 03'28.8562" S

Current Status:

The Elk-2 well is currently at a total depth of 7,412 feet (2,259 meters) and within the Orbulina Marl, above the limestone reservoir target. The Orbulina Marl was encountered at approximately 7,028 feet (2,142 meters) based on the calcimetry and other geological indicators obtained while drilling. Sonic and Formation Micro Imaging (FMI) logs were run in the open hole from 7,412 feet to 5,939 feet.

Drilled 8 1/2 inch hole to 7,412 feet and ran and cemented 7 inch casing (liner) to 7,412 feet (2,259 meters) with top of liner at 5,755 feet (1,754 meters). Installing BOP and rotating head. Preparing to perform check shot and VSP survey, and then drill out into the Puri limestone formation, followed by a Drill Stem Test (DST).

Levels of background gas ranged from between .010% to 2.67%, with C1 (Methane) to C5 (Pentane) encountered while drilling through the lower Orubadi and Orbulina Marl transition. Connection and trip gas levels, ranged between 0.8% and 34.95%.

(note: previous wells drilled in the area have experienced background gas, however background gas in no way confirms commercial accumulations of hydrocarbons reached to date on this well, until the well is drilled out and testing and logging is completed. The structure may need further geological, geophysical and appraisal work before a commercial confirmation of gas reserves.)

Past Data:

Set 9 5/8-inch casing to 5,939 feet (1,810 meters) and cemented in place. Installed a down hole deployment valve (DDV) within the 9 5/8-inch casing at 3,419 feet (1,042 meters). Set 18 5/8-inch surface casing at 177 feet. Drilled a 17 1/2-inch hole to 1,919 feet (585 meters), followed by setting 13 3/8-inch intermediate casing at 1, 913 feet (583 meters).

Planned Total Depth:

Approximately 10,000 feet (3,050 meters)
