Summary
We studied the stability of multilateral (ML) junctions in a combined experimental and numerical modeling program. The experiments were carried out in a true triaxial machine on large cubic blocks (40 cm) of weak triassic sandstone with two holes intersecting. Six tests have been performed with two different geometrical configurations and three different stress states. The experimental results are presented and compared with numerical modeling obtained with finite-element software developed for assessing the integrity of rock surrounding an ML junction. |
