After sleeping on this overnight is it not terrible news at all !!!
Looking at the diagram ... its been draw to make perfect logical sense.
If you trust the Management they say, and i quote;
Indirect Vertical Fracture Completion (IVFC) technique. This technique is quickly becoming the preferred method in the US shale gas industry as it utilises gravity assisted drainage of the reservoir and can offer better fracture initiation due to the mechanical properties of the formation. The interburden displays such
properties and Strike along with Halliburton have tested the efficacy through fracture modelling
Drilling into the underburden IMO will produce a better result ....... I was always concerned about caviation issues, which presented when they drilled into the brittle coal bed.
What concerns me now is not knowing anything about IVFC.
We could ALL benefit from reading anything on IVFC , and hopefully someone can post some technical links not just on the theory, but precedence where it has been used successfully. I believe Shell were using this in China for their deep long runs.
Anyway I see this change as an improved technique and decreases the risk associated of drilling directly into the brittle CB. The picture looks good, but i am more interested now in understanding the technical aspects of IVFC. Calling for 4c is absurd. We need to trust Haliburton know what they are doing, and have they done this successfully before .... well have they ??? is the real question....
