Abstract

•From visual inspection and sample preparations, it is obvious that the sandstone from layer “A” at 1634m depth is poorly consolidated and little cemented.•The results from destructive geotechnical/rock mechanical tests support the macroscopic observation, that the sample is poorly consolidated compared to its depth of deposition.•The tests suggest that the sample has somewhat higher porosity than that measured in other wells at the Heletz site and by other methods.•Low strength of the sample may result from stress transfer or pore pressure build up.•To determine the epistemic uncertainty of the results, further tests of the reservoir rock is required.
