Armour Energy Begins Drilling Campaign at Myrtle Basin 1 Well in EP 176

change text size

Australia-listed Armour Energy Ltd announced Monday that the 2013 Northern Territory drilling campaign in Australia has commenced with spudding of the Myrtle Basin 1 well on Sept. 13 in the Company’s 100 percent owned exploration permit (EP) 176. The well is currently at 498.6 foot (152 meter) depth after drilling with an air hammer achieved penetration rates of between 98.4 and 131.2 feet (30 and 40 meters) per hour. In the next 24 hours, Armour Energy will run casing, cement in place and recommence drilling.

The 2‐3 well exploration program is as follows:

  1. Myrtle Basin 1
  2. Lamont Pass 3 and
  3. Optional: Caranbirini 1

The Northern Territory campaign has been designed to further evaluate:

  1. conventional gas accumulations within the Coxco Dolomite to potentially convert up to 264.4 billion cubic feet (Bcf) of Mean Prospective Resources to Contingent Resources from 23 identified prospects; and
  2. the unconventional potential of the Barney Creek Shale Formation.

Coxco Dolomite Unconventional Prospects

In April 2013, Armour Energy announced unrisked Mean Prospective Resources of 264 Bcf relating to 23 targeted areas in the Coxco Dolomite of the Teena Formation, a conventional, free flowing reservoir in the Batten Trough, McArthur Basin. This type of conventional gas accumulation was discovered by Armour in the course of drilling the Glyde 1 ST1 lateral well in August 2012 (which flowed 3.3 million cubic feet per day, or MMcf/d) and occurs within the porous and permeable dolomites and breccias of the Coxco Dolomite.

Barney Creek Shale Formation

As with the Cow Lagoon 1, Glyde 1 and Glyde 1 ST1 wells, Armour continues to gather extensive data to further substantiate the unconventional resource potential of the Barney Creek Shale Formation. Several studies are underway that will aid further targeting of a future lateral well with hydraulic stimulation in the Barney Creek Shale Formation.

The gas discovery at the Glyde 1 vertical well drilled in August 2012 substantiated MBA Petroleum Consultants’ estimate of Mean Prospective Resources of 18.6 trillion cubic feet (Tcf) in the Barney Creek Shale within EP 171 and EP 176.

Myrtle Basin 1 Vertical Well

The Myrtle Basin 1 vertical well will be drilled to a planned depth of 2,624.6 feet (800 meters) and is located approximately 10.5 miles (17 kilometers) south‐west of the McArthur River Mine and approximately 3.1 miles (5 kilometers) southeast of the McArthur River Pipeline. The Myrtle Basin 1 location is designed to evaluate shallow hydrocarbon accumulations in the Barney Creek Shale and Coxco Dolomite that are similar in depth to the Glyde 1 & Glyde 1 ST1 (1,968.5 feet or 600 meters) gas discovery locations. Shallow mineral holes in the area have reported oil bleeding from core and gas to surface.
