  • Well activity:  37 gross wells (10 net) were placed on production. 38 gross wells (13.1 net) were spudded during the quarter, which includes 7 wells on Aurora operated acreage. In total, there were 332 gross wells (87.5 net wells to Aurora) on production at quarter end.
  • Drilling status:  At the end of the quarter, drilling operations were underway on 12 gross wells, 21 gross wells were awaiting fracture stimulation and 10 gross wells were being stimulated or were being prepared for test.
  • Operated acreage:  First production commenced from two Heard Ranch wells in late September on Aurora operated acreage. During October, production from these two wells posted a 30 day average rate of 821 boe/d per well. An additional two Axle Tree wells were drilled and multi-stage zipper fracced in the third quarter. During October these two wells were placed on production.

Sugarkane Field - Eagle Ford Shale

Aurora's primary asset is its interest in the Sugarkane Field in South Texas, which is located in the core area of the Eagle Ford shale. Aurora participates in approximately 80,300 highly contiguous gross acres that make up the field. Marathon Oil EF LLC, a wholly-owned subsidiary of Marathon Oil Corporation (NYSE: MRO) ("Marathon"), operates approximately 77,600 gross acres and Aurora is the largest non-operating working interest partner in this area. In addition, Aurora has a 100% working interest and is the operator of 2,700 acres within the two areas, Axle Tree Ranch and Heard Ranch, located in the Sugarkane Field as shown in Figure 1.

At the end of the reporting period, Aurora had a net position of approximately 22,100 acres within four adjacent non-operated Areas of Mutual Interest ("AMIs") and two operated areas in the Sugarkane Field. The varying levels of participation are outlined in the table below and the AMIs are shown in Figure 1 above.

AMI Working Interest Gross Acreage Net Acreage
Sugarloaf 28.0% 24,000 6,750
Longhorn 31.9% 28,700 9,100
Ipanema 36.4% 4,800 1,750
Excelsior 9.1% 20,100 1,800
Operated acreage 100.0% 2,700 2,700
Total   80,300 22,100


There were between 7 and 11 rigs drilling at any one time on Aurora's non-operated Sugarkane acreage during the reporting quarter and up to two rigs on Aurora's operated acreage. A total of 38 gross (13.1 net) wells were spudded, 7 of which were on the operated acreage.

During the reporting quarter 37 gross (10 net) wells were placed on production including Aurora's first two operated wells. Aurora had an inventory of 31 gross wells at the end of the quarter awaiting commencement of fracture and stimulation operations.

The following table details activity status within the Sugarkane Field as at September 30, 2013:

A variety of well intervention operations have taken place across a number of wells in which Aurora has an interest. Artificial lift installations took place in 68 wells across Aurora's non-operated acreage. These are routine planned operations which are implemented as individual well reservoir pressures drop.

Drilling activity during the quarter within the Sugarkane Field utilized multiple well pads, where between 2 to 6 wells were drilled from the same surface pad location. Such pad drilling offers cost and efficiency savings via sharing of infrastructure and avoiding lengthy rig and fracture stimulation equipment moves. Further efficiencies are expected with several pads undergoing batch drilling, whereby the vertical surface hole section of wells at a particular pad location are all drilled first, followed by all of the horizontal sections. This batch approach allows equipment and operations to be configured for a particular repeatable phase of operations resulting in efficiency gains.

Operated Acreage

On Heard Ranch, first production was established on Aurora operated acreage from two wells, the J.P. Bower-Heard 19H and 20H. Production from these two wells posted a 30 day average rate of 821 boe/d per well. These wells were pad drilled and cased at lateral lengths of 7,800'-7,900'. The wells were then zipper fracced using the Schlumberger HiWay frac system. The Nabors F08 rig then moved to a nearby pad and has spudded a three well pad program. These three wells are expected to be drilled and completed before year end.

At our Axle Tree Ranch, the Julie Beck #12H and #13H wells were drilled and multi-stage zipper fracced. After quarter end these two wells were placed on production.

In addition to drilling operations, installation of pipelines, central gathering infrastructure and facilities is well underway.

Down Spacing and Austin Chalk Update

Aurora continues to evaluate several pilot studies currently underway in both the Eagle Ford and Austin Chalk. Aurora anticipates developing its operated Eagle Ford acreage under a 40 acre development plan. On the non-operated acreage, more than 30% of the wells drilled to date have been on less than 80 acre spacing. Aurora plans to provide details of the planned density pattern in the Eagle Ford formation across the non-operated acreage prior to calendar year end.

Pilot programs continue to evaluate possible co-development of the Austin Chalk and the Eagle Ford. These pilot programs will consider multiple lateral placements within the two reservoirs.


The following table provides details of the Aurora production during the quarter, which comprised 80% liquids on a boe basis.

*The oil equivalent barrels per day production rate has been calculated on a 6:1 ratio of gas to oil.

Average daily production for the month of September 2013 from both non-operated and operated Sugarkane Field was 22,175 boe/d gross (16,310 boe/d net).  Monthly average  production rates will continue to be less linear as the majority of wells are now drilled in batches ("pad drilling") and are completed and placed on production in groups rather than individually.

The graph below shows the quarterly production profile for the past 5 quarters. The figures shown at the base of each production bar reflect the incremental net wells added during that period. As indicated in Aurora's 2013 guidance, activities will be weighted to the second half of the year and production is expected to increase accordingly.

*includes 11 existing producing wells acquired as part of the Heard Ranch/Axle Tree Acquisition in March, 2013

Regional Eagle Ford Shale activity

The Eagle Ford shale is recognised by the industry as the one of the premier shale plays in the US. High liquids content, strong well performance (particularly in the core of the trend) and significant regional infrastructure drive attractive economics.

As a result activity levels have remained high, with 234 rigs reportedly currently operating within the trend which has increasingly focused on the core areas. The Sugarkane Field lies within the core area. The Texas Railroad Commission reported 2013 average oil production rate through July of over 600,000 boe/d from the Eagle Ford.

Quarterly Revenue and Capital Expenditure

Aurora's revenue from oil and gas sales for the third quarter of 2013 totalled US$144 million (US$105 million after royalties).

Total development capital expenditure, including accruals for the quarter totalled US$140 million representing development undertaken at the non-operated acreage within the Sugarkane Field and at the adjacent operated Axle Tree and Heard Ranches during the quarter.

At September 30, 2013 the cash balance was US$106 million. In addition, the Company has further liquidity available from its revolving credit facility. At the end of the third quarter, this debt facility was undrawn with a balance of US$300 million available.

Aurora anticipates the third quarter unaudited Interim Financial Report and Management's Discussion and Analysis, prepared in accordance with Canadian securities legislation requirements, will be filed on or about November 8, 2013.

Cautionary and Forward Looking Statements

Aurora 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.

Numbers in the tables above may not add due to rounding.

References herein to "Sugarkane" or the "Sugarkane Field" are references to the Sugarkane natural gas and condensate field within the Eagle Ford and includes the two contiguous fields designated by the Texas Railroad Commission as the Sugarkane and Eagleville Fields.
