· Test 6 was a late gas flow start with ca. 3000 pore volumes of gas flowed before sand onset. The test was stopped quite early after sand onset at ca. σN = 0.2 with 21 g of sand produced. Post failure imaging showed only small breakouts in the specimen. In Tests 7 and 8 gas and water flowed simultaneously.

· Sand production is a major problem that the oil and gas industry has been facing for years. It can lead to loss of production, equipment damage or complete well abandonment. Prediction of sand has been historically challenging due to the periodic nature of sand production, insufficient laboratory tests and lack of field tests validation.

· Large amounts of sand production in a short period of time may clog up wells, damage well equipment, and destabilize wellbores due to loss of materials (Climent et al., 2014). On the other hand, controllable sand production may increase wellbore productivity and reduce wellbore completion costs ( Saucier, 1974 ).
