In addition, the higher the internal pressure, the greater the maximum stress of the casing in the annular missing section. Increasing the elastic modulus of cement sheath by adjusting the mud composition is a reasonable method...

... is developed. The effects of creep time, eccentricity distance, cement sheath modulus of elasticity and internal casing pressure on wellbore stress were investigated using the finite element method. The results show that for a given eccentricity, the stress on the wellbore increases with creep time, affecting...

... the mechanical parameters of the two regions. The results show that both groups of samples have strong inhomogeneity and rich microscopic pore structure, with a larger elastic modulus of 35.23 GPa in the Jimsar Basin and a smaller elastic modulus of 26.78 GPa in the Bohai Bay Basin. In addition, the simulation...

.... The primary objective of this study is to measure the fracture fluid viscosity and elasticity of HVFR and linear guar at room temperature (21°C). Secondly, this work evaluates the proppant settling across HVFR at 3 gpt and linear guar at 20 ppt concentration, using a static model and two mesh sizes (40 and 70...
