Ok let's have a geometric lesson here on blocky and thin sands. A thin sand at the well bore can be the pinch out of a large sand similar in shape to a triangular section. Some thin sands known in some fields I won't mention produce more than blocky sands. You can put figures or % on them at this stage in my opinion they need to be commingly tested and evaluated to find out if there are any thief or non producing sands this is the only way to evaluate and calculate these type of sands. Cheers give me a multi net thin sand equivalent to a blocky sand any day they are like a box of chocolates??!!!
