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...

Acidizing and wormholing in carbonate reservoirs is studied through the analysis of the linear acidizing problem theoretically and experimentally. Experimentally, linear acidizing tests were performed in Mons chalk, a high porosity analogue of North Sea reservoir chalk. In the experiments the critic...

Increasing the profitability of sand producing fields requires sand management and accurate predictions of sand onset and sand mass such that well completion geometry and method and drawdown and depletion during the life of the well is optimized. Sand production models have not been proven under ful...

Four failure criteria, a simplified Mohr–Coulomb, a Mohr–Coulomb, a von Mises and a Drucker–Prager model are considered for borehole failure and sand onset predictions. The von Mises is a special case of the Drucker–Prager. The resulting analytical expressions are suitable for implementation in the ...

Borehole stability and sand production in gas reservoirs is studied and a mechanism that explains the observed higher borehole strength and delayed sand onset is advanced. This mechanism takes into account the drying of the connate water in the reservoir rock due to gas decompression near the boreho...

The present work investigates the Knoop hardness of rocks and other pressure sensitive materials. We tested ten different types of rocks, a cement paste, and PMMA. We also analyzed existing experimental results for Mg-PSZ (magnesia-partially stabilized zirconia) and Pb Ni P 40 40 20 metal glass. We p...
