Sand in the oil stream with the risk of well collapse is a well-known problem when sandstone reservoirs approach depletion. Advanced sensors and a super machine are helping research scientists to find the threshold at which profitable production ceases. This can increase the lifetime of reservoirs....

In this paper we have studied the effects on fracture initiation and propagation by precooling the borehole region, using our recently developed novel true triaxial apparatus, giving us the capability of recreating fully anisotropic stress conditions with a semi-circular sample geometry. The results...

Increasing the profitability of sand producing fields requires sand management and accurate predictions of sand onset and sand mass such that the well completion method and the drawdown and depletion during the life of the well is optimized. Sand production research has seen significant advances thr...

Using a novel true triaxial setup, sand production tests on hollow quasi-cylinder Castlegate sandstone specimens have been performed on irreducible water saturated specimens with oil flow under varying levels of axial and lateral stress anisotropy, obtaining sand onset and rate. The experimental res...
