AWE reported that at 0600 hours (WST) the drilling and formation evaluation program for the Arrowsmith-2 exploration well has been completed and the well has been suspended. The Weatherford 826 rig is currently rigging down in preparation for demobilization.
During the week, the well has been deepened to a total measured depth of 3,340 meters having intersected all objective intervals. A full suite of wireline logs have been run to evaluate the target formations. Progress for the week was 238 meters.

Initial log and core review from the Arrowsmith-2 exploration well indicates that a 460 meter section of Kockatea Shale has been intersected overlying a 250 meter section of Carynginia Formation. Beneath the Carynginia Formation a 330 meter section of Irwin River Coal Measures and a 22 meter section of High Cliff Sandstone have been intersected. Elevated gas readings while drilling have been observed throughout the target sections and these will be further analyzed as part of the post drilling evaluation. The two lower shale sequences (Carynginia and Irwin River) have been conventionally cored as previously announced and rotary sidewall cores have been acquired throughout the shale sequences including the Kockatea target section. Further sidewall cores have been cut and recovered from the secondary High Cliff Sandstone conventional target.

The conventional and rotary sidewall cores have been transported from the drill site and these will undergo detailed core analysis (tight rock and mechanical rock properties analyses). The results of this work will be used to assist in the design of the hydraulic fracture stimulation program and flow testing of the well which will be undertaken during the third quarter.

The Arrowsmith-2 well is located approximately 25 kilometers from the Woodada Deep-1 well (deepened by AWE in April 2010 to acquire cores over the Carynginia Shale interval), and approximately 500 meters south east of the Arrowsmith-1 well.

The participants in EP 413 are:

• AWE Limited (via subsidiaries) 44.252%
• Norwest Energy NL (Operator) 27.945%
• Bharat PetroResources Ltd 27.803%

Norwest Drills Ahead at Arrowsmith Well

- Norwest Drills Ahead at Arrowsmith Well

Thursday, June 09, 2011
AWE Ltd.

AWE reported that at 0600 hours today (WST) the Arrowsmith-2 exploration well was drilling ahead at a measured depth of 2,291 meters after running and cementing 9-5/8" casing at a measured depth of 2,284 meters, as planned. Progress for the week was 1,691 meters.

The Arrowsmith-2 well is designed to test the unconventional gas potential of the Carynginia Formation, Irwin River Coal Measures and Kockatea Shale and will be drilled to a proposed total depth of approximately 3,420 meters.

The well is located approximately 25 kilometers from the Woodada Deep-1 well (deepened by AWE in April 2010 to acquire cores over the Carynginia Shale interval), and approximately 500 meters south east of the Arrowsmith-1 well, which tested gas from the Carynginia Formation.

During drilling, the joint venture is planning to cut conventional cores from the middle Carynginia Shale and Irwin River Coal Measures. On completion of drilling, the well will be suspended for future fracture stimulation and testing which is planned for later in the year.

The participants in EP 413 are:

Norwest to Conduct FTG Survey in Northern Perth Basin

Norwest to Conduct FTG Survey in Northern Perth Basin

Thursday, April 07, 2011

Norwest Energy NL

Norwest has been awarded a Special Prospecting Authority – STP-SPA-0013 (SPA) to conduct an FTG survey to evaluate the hydrocarbon potential over 21 onshore blocks in the Northern Perth Basin. The SPA extends Norwest's footprint in the Basin across a significant area with shale gas potential.

The SPA covers an elongated onshore area running along the Western Australian coast, located between Cervantes and Eneabba (see Figure 1), and covering an area of ~860km2 (212,522 acres). As depicted in Figure 1, the SPA lies to the south of Norwest's TP15 (offshore) and EP413 (onshore) acreage, and lies geologically between the north–south striking Urella Fault and Beagle Fault systems. The sedimentary section on the block is known to contain thick shale formations, principle amongst which is the prolifically developed Kockatea Shale, which is mature for gas, with significantly high total organic carbon (TOC) content in the area of the SPA.

The potential for shale gas in the region is further supported by a third party study commissioned by Norwest in mid 2010 to report on shale gas potential within the area. Two wells included in this study were Point Louise-1 (drilled in 1981) and Jurien-1 (drilled in 1963), both located on the western side of the Beagle Fault, and both of which showed favorable indicators for shale gas. The report stated that the Kockatea shales have the potential maturity to produce gas, contain fair TOC content and are composed predominantly of type II kerogen. Both wells intersected thick sections of the Kockatea Shale, with Point Louise-1 intersecting 459m and Jurien-1 247m.

The SPA is valid for six (6) months during which time Norwest will acquire an airborne, full tensor gradiometer survey (FTG) on the area. The FTG survey is designed to more accurately identify potential basement related fault blocks and adjacent deep troughs suitable for unconventional shale gas targets. If the FTG results prove favorable, Norwest has a further six months to submit an application for a petroleum exploration permit over the SPA area. Norwest is experienced in the acquisition and application of the low impact FTG Survey technique, having successfully deployed the technology on both TP15 and its Southern England acreage. The recently drilled Red Hill South-1 well located within TP15 was evaluated using FTG, and while the presence of commercial hydrocarbons was not established at Red Hill South, it was considered a technical success, with FTG playing a major part in selecting the well location. The geology encountered during the drilling program proved consistent with the FTG modeling results.

In a statement made on behalf of Norwest Energy, CEO Peter Munachen said, "This SPA application was made some time ago, and forms an integral part of Norwest's strategy to further develop its stake in the emerging shale gas plays within the Northern Perth Basin. Shale gas is now a proven, significant resource in North America, and Norwest is determined to play an important role in developing shale gas resources within Western Australia. The company's location is also favorable for supplying the Western Australian domestic gas market, with two pipelines running through the basin – the Dampier-Bunbury and the Parmelia gas pipelines. The successful grant of the SPA can be considered a further advancement in Norwest's bid to become a major player in the development of the significant shale gas resource that exists in the Northern Perth Basin."
