ABSTRACT: Sand production in poorly consolidated and unconsolidated clastic reservoirs has costs associated with corrosion of field equipment and damage to surface facilities. Estimating the onset of sanding and the amount of sand produced is crucial to any successful sand management strategy. Orientation of in-situ stress also plays a key role. This paper explores the relationship between the orientation of the failure observed in an advanced thick wall cylinder (ATWC) test and the measured velocity profile in an azimuthal velocity anisotropy (AVA) measurement. Integration of a high accuracy load cell into the ATWC test enables the detection of onset of failure and measurement of the volume and rate of sand production. Results of ATWC tests showed that the orientation of failure occurs in either of the significant axes of the AVA profile (either the minimum or the maximum velocity orientation). The results of the ATWC test can be used as input to commonly used sanding models. Incorporating the AVA measurement into the ATWC workflow and comparison of results may provide additional insight into the stress memory of the rock.
