Great analysis Petro. Thanks for taking the time. Always good to see another trained voice join the debate.
My question to you is how variable the porosity of these reefal formations typically are and is there any reason to suspect the general porosity characteristics seen across A1, A2 and A3 are likely to be consistent across the same sedimentary layers revealed in the 2D seismics?
When I imagine a large coral reef of today it is a fairly well defined linear structure. In 150 million years today's reef will have changed but it should still be that same basic structure, shouldn't it? Yes, pressures and chemistry and erosion will have taken their toll, but how variable could we expect that to be in other parts of the Antelope structure given the coring results seen so far?
Maybe questions without answers but I thought I'd ask anyway.
