Burleson is on the verge of a very exciting phase. Since the Board of Burleson made the decision to change focus to drilling targets with conventional (mainly Wilcox) reservoirs, we have had considerable success. Three Heintschel field wells are now on production with higher condensate:gas ratios than initially anticipated, and the Joann #1 will be tied to sales shortly.

Following this success (four of the five wells drilled in Colorado County are producers) the Board was faced with two choices in terms of a forward program: a slow path that allows cash flow from the producing wells to accumulate in order to fund the drilling of a small number of wells within the next 12 months; or, raise significant funds to enable Burleson to embark on an aggressive campaign involving both a faster appraisal/development campaign for the Heintschel field and the drilling of additional exploration wells on very high quality prospects. The Board has decided to pursue the latter choice.

The exploration wells will mainly target Wilcox reservoir sands, which have been the core of Burleson's success, but we will also look to fast track drilling of the potentially very large deep Woppa prospect which has Edwards and Sligo carbonate reservoirs (and also includes Eagle Ford Shale targets).

Heintschel field update

Discovered in April 2010 by Heintschel #1 and appraised by D.Truchard #1 and Heintschel #2 in December 2010 and January 2011, the field now has those three wells on production. Current indications are that the Heintschel field may be one of the largest discoveries of its kind in a region which has hundreds of Wilcox fields.

Following the Heintschel #1 discovery well, operator AKG Energy undertook an evaluation of the volumes of gas and condensate in the field.

Based on the results of the two recently drilled Heintschel field appraisal wells (D. Truchard #1 and Heintschel #2), Burleson Energy's US partner and operator, AKG Energy, has re-calculated the volume estimates for gas and condensate in the Heintschel field resulting in substantial increases.(ASX announcement 10 March 2010).

Burleson has a 38% working interest and a ~ 30% net revenue interest in the field.

The intention is for an independent reserves study to be commissioned after two to three months production data has been obtained.

Background to the Volume Estimate Calculations

The original estimates for the field were determined using 3D seismic data and data from a single well - the Heintschel #1 discovery well. The condensate volumes were calculated using the condensate: gas ratio observed during the initial, pre-frac flow from the well. Subsequently, two appraisal/development wells were drilled into the field. D Truchard #1 and Heintschel #2 located 2.9 and 0.37 km, respectively, from the Heintschel #1 discovery well.

These new well penetrations enable more accurate estimates of gas and condensate volumes to be calculated. A greater thickness of gas/condensate charged sands in D Truchard#1 (with no water contacts) and the higher, post-frac condensate:gas ratio in all three wells have led to increases in the volume estimates.

The first step involves calculation of the hydrocarbons in place - i.e. the gas and condensate located within the pores of the reservoir rock. These are estimated by determining reservoir rock volumes by 3D seismic and reservoir thicknesses in the wells. The rest of the variables for the calculation are provided by well logs (including porosity, water saturation etc). Note that the above numbers for "in-place" volumes are not directly comparable to the initial estimates which were of recoverable volumes.

At this early stage, it is not possible to make a rigorous determination of what volumes will ultimately be recovered from the Heintschel field. AKG has provided the numbers in the table, above, which are based on the assumption that the wells will produce until the pressure is depleted to 50% of the original reservoir pressure, a figure that has been commonly achieved in analogue, pressure depletion type Wilcox fields in the region. This is a standard and reasonable approach, but the reliability of the assumption will not be known until several months production history has been achieved.

Modest, scaled down fracs undertaken on D Truchard #1 and Heintschel #2 suggests that they are not producing at optimum rates. The 3 producing wells on the field are being monitored and the production characteristics of these wells will enable the development of a frac design that will yield the maximum well producibility which will, in turn, determine the ultimate recoverable reserves for the field. Field development planning, including well spacing, frac design, water disposal and potential for horizontal drilling, will advance as more well production data becomes available.

Update on Heintschel Production

The three wells in the Heintschel field have been producing at relatively stable rates over the past two weeks with average production for the first week in March of 3,250 mcf gas/day and 125 barrels of condensate/day. Associated water production averaged 800 bpd which was managed through trucking whilst water disposal alternatives (such as drilling a shallow water injection well) are further considered.
These flow rates have been achieved despite (as noted above) limited fracs being applied to the Heintschel #2 and D.Truchard #1 wells, as well as experimentation with various choke sizes at each well to gather production data. Options are being evaluated to enhance the performance of the wells - potentially including re-fracs and other methods including artificial gas lift.

Importantly the condensate production confirms higher than anticipated rates of condensate which enhances the attractiveness of the field especially considering the recent rise in oil prices. The current oil price is ~A$105/barrel with the gas price at ~ A$3.90/mcf. Based on the current production rates and these hydrocarbon prices, these three wells generate BUR approximately A$230.000 (net) per month.

In summary, Burleson has discovered a very large resource at Heintschel, but we are still learning about the field and how best to develop it. Current plans are to monitor and evaluate our first three wells in the field for up to three months in order to optimise the development of this resource.

The Joann #1 well (BUR WI 39.4%, NRI 30.73%) made a gas condensate discovery in July 2010.

It is currently shut-in awaiting connection to a sales pipeline but prior to this the well was tested.

One of four prospective zones identified by logging in Joann #1 was perforated and flowed gas at 2.1 million cubic feet of gas per day and approximately 38 barrels of condensate per day.

Wildcat Drilling to Resume

While we monitor production and implement development of the Heintschel field, Burleson will bring forward and increase our wildcat exploration drilling program. There are a multitude of high quality Wilcox prospects already in the inventory (see the latest presentation announced to ASX on 3 February 2011). Some are Heintschel "look-a-likes" and others of different nature occur in the original 3D area, while some occur elsewhere in Colorado and Wharton Counties.

The Board believes it is also time to kick off the "1K3D" project in which Burleson has 38% of a right to secure another 1000 sq miles of 3D seismic from a large seismic data base (see announcement of 29 June 2010). The value of this amount of 3D seismic (or equivalent 2D seismic) to Burleson is estimated to be ~A$4m. This seismic project will provide Burleson with numerous new wildcat drilling targets (with various reservoirs). A significant amount of geotechnical work and leasing is required before we will be in a position to drill any prospects generated by this project, and as the offer of seismic data lapses in late 2013, the Board is keen to progress that work.


This is a very large, deeper prospect with stacked Edwards and Sligo carbonate reservoirs and is on trend from (and deeper than) the 600 bcf producing "Word" Field and other large Edwards fields. A deep well on Woppa would intersect the following potential reservoirs at depths more than 15,000 feet: Austin Chalk (uppermost); Eagle Ford Shale; Edwards Carbonate; Sligo Carbonate (deepest).

Burleson is looking to farmout part of its interest in the well but will also consider contributing to the cost of the well to get it drilled.


These are very exciting times for Burleson.

Firstly, it is not often that one gets the opportunity to make and develop a potentially significant discovery such as Heintschel from initial concept, to data acquisition, to prospect delineation, to discovery, to appraisal/development.

Secondly, our interest in the large 1K3D seismic project will provide us with a multitude of high quality exploration prospects for future drilling in addition to our already substantial portfolio of targets.

Thirdly, drilling of the very large, deep Woppa prospect would expose Burleson to "Company Maker Size" exploration, which if successful, would result in a massive re-ranking of the Company.
