Drilling Status Report – 7 May 2007
• Paradox Basin #1 oil & gas well, Grand County, Utah, has successfully reached its final depth of 16,471 feet (5,020m) in the Cambrian Lynch Dolomite
• A geophysical wireline survey was completed
• The Company has opted to use the current rig to proceed immediately to well completion, initially testing the Pinkerton Trail Formation gas show, to be followed by gas shows in the Alkali Gulch, Barker Creek, Akah and Upper Ismay intervals
PARADOX BASIN #1 OIL & GAS WELL, UTAH USA
The Directors of Golden State Resources are pleased to announce that the Paradox Basin #1 oil & gas well has successfully reached its total depth of 16,471 feet (5,020m) after passing into the Cambrian Lynch Dolomite at 16,368 feet (4,989m).
DEVELOPMENT AND PRODUCTION
The Company has elected to use the current drilling rig to proceed immediately to well completion (the process of finishing a well so that it is ready to produce natural gas), given the difficulty in acquiring a work-over rig capable of operating to depths in excess of 15,000 feet (the depth of the Pinkerton Trail Formation gas show).
Testing of the Pinkerton Trail gas show will commence within 36 hours. The production potential for the intervals annotated below will be known within two weeks.
As a first priority, perforation and testing will be undertaken on the following gas shows:
Upper Ismay 9,845’ - 9,858’ 3,001 - 3,005 Gas in dolomite reservoir rocks at up to 520 units, with connection gas levels up to 3,000 units.
Akah 10,815 - 10,834’ 3,296 - 3,302 A gas show of up to 790 units.
Barker Creek 12,558’ - 12,580’ 11,015’ - 11,031’ 3,828 - 3,834 3,357 – 3,362
A major pressured gas interval in dolomitic sandstone. Gas (methane, ethane and trace propane) was present at levels of up to 2,300 units, with connection gas up to 3,300 units.
-- A 16’ gas-bearing interval (390 units), in a sandstone unit marking the top of the Barker Creek member.
Alkali Gulch 13,097’ - 13,106’ 13,145’ - 13,154’ 3,992 – 3,995 4,006 – 4,009
Two significant gas intervals in vuggy dolomite between salt horizons, with gas levels up to 800 units. The host dolomite was the best quality reservoir rock seen in the well.
Pinkerton Trail 15,288’ - 15,321’ 4,660 – 4,670 A significant show over a 33’ interval within a strongly fractured cyclic sequence of limestone and black shale, with gas up to 1,020 units.
Other oil and gas shows in other formations, may be assessed in conjunction with the above intervals.
Following the completion of a geophysical wireline survey, the Mississippian to Cambrian bottom interval of the well was plugged to allow development of the upper Pennsylvanian section of the well.
Drill Stem Test – Leadville Limestone Fm
The drill stem test on the Mississippian Leadville Limestone target yielded water at this depth, indicating that the Leadville target will be better tested further up dip, above the inferred oil/gaswater interface (see diagram below). The proposed second well for the project targets the Leadville Limestone one mile (1.6 km) up dip to the SSW, and would intersect the Leadville Limestone 1,000 feet (305 m) higher vertically above the intersection in Paradox Basin #1. Permitting is currently under way for the next location.
PRODUCTION PERMITTING
Permit applications for a connector production pipeline to the nearby Williams Northwest Pipeline have been lodged. Permitting for an onsite gas plant awaits completion of the well.
