In this latest presentation the fracture efficiency is a significant topic, it along with greater horizontal length forms the basis for predicting an IP30 flow of 1500bpd of hydrocarbon liquids.
Doubling the horizontal length and thereby doubling production is simple enough, but bear in mind as the length grows, so does the difference in pressure along it, making the back end fractures a little less productive.
Fracture efficiency is more interesting, in that the post frack and flow analysis, shows at only 20%
PANR are factoring a doubling of this efficiency to 40% in the modelling, and this is calculated into the economic modelling.
When going back through the webinar, 40% appears an interim and conservative target.
To summarize PANR know why only 20% efficiency was achieved, and how to fix it. Gaining the data from the ALK 2 fracture stimulation performance, has been a required step to get here, as it is in all new basins, knowing how the rock fractures in a live environment puts you in a position to optimize, and the end goal is 80% efficiency, as is achieved in other basins
In the second quote below, a quick summary would be, using a proven fracture design, Tony has recently used in the Permian basin, and applying it to the Alkaid physical reservoir properties, the model spits out 80% efficiency.
Tony Beilman comments transcribed from the webinar
“That is typical with Gen 1 and Gen 2 type jobs, when people first get into a basin, but once you get a clear understanding of how the Basin treats, you should be in the 80% numbers. “
“So I took the Alkaid 2, and I implemented this Frac design, that we did in the Permian Basin, and this is the result, this is again the same material balance that we discussed earlier , and this time we we upgraded the production to reflect what an additional contact area would look like, and this is the match that we've got, and again same layout, you see the pressure response, and the production response. In the upper left you see the tight curve, in the lower left, and you see the calculated area, in the upper right again that, those blue and red lines is just a probabilistic area, of what we wanted to calculate to see how close we are to it, the thing I would like to take away from that, and you see it in the box, and we also see it in the in the circle, is that our drainage area doubled, and our horizontal extension almost doubled, and what that that gave us, and really in the circle you can see it, are where we were talking about, six stages out of 32 being the efficiency, We're now at, 28 out of 32 so we're now in that 80 window that we talked about wanting to achieve, and so that's where we plan on going forward with”
