... integrity under multi-cycle. During the steam injection process, cyclic heating and cooling cause significant changes in wellbore temperature, posing a significant challenge to the long-term integrity of the cement sheath. On the one hand, the elastic modulus and compressive strength of cement will show...

... compressive strength of cement upon exposure to high-temperature conditions. Current Scope of Study The focus of this study is to evaluate the impact of silica particle size on the early compressive strength development of class G cement at elevated temperatures. A density of 15.8 lbm/galUS is selected...

... the factor of 3.6, by a very large margin. This provided project confidence that the steep slopes within the vicinity of the flowline are indeed stable under a seismic event. The flowline is demonstrated to be free from the threat of a mass gravity flow impact. structural geology strength geologist...

... compressional acoustic waves and show poor bonding, if recorded sooner than the time needed by cement downhole to achieve full compressive strength. Existence of a casing-cement gap, in a micro-annulus condition, also affects attenuation of compressional wave, making it difficult to differentiate from poor bond...

... core. All cable metallurgy needs to maintain the required tensile strength and corrosion resistance for up to 15% H 2 S. A fit-for-purpose, computer-modeled finite element analysis (FEA) was carried out to identify potential showstoppers, followed by two independent empirical tests. Various cable armor...
