Abstract: Deepwater shallow sediment is lessconsolidated, with a rock mechanical behavior similar to saturated soil. It is prone to borehole shrinkage and downhole leakage. Assume the deepwater shallow sediments are homogeneous, ...

Abstract: Wellhead subsidence is one of the most severe engineering disasters during drilling operations in cold regions. Based on the characteristics of thaw-induced settlement of frozen soil, a thermal–fluid–soil coupling numerical ...
