These analyses are the reservoir compaction, displacement of ground surface, integrity of the caprock and the stability of the natural fractures and faults during the depletion and injection phases of the UGS operation. The targeted storage rocks are stiff with Young's modulus more than 50GPa...

... analyses over the life of the field. The results shows that a stress path of approximately 0.69 is expected in the carbonate reservoir. This is while the stress changes in the caprock layer is relatively lower, and as expected, with a reverse trend. This is mainly because the reservoir compaction...

... Abstract We present a simple analytical solution to diagnose gas production under compaction. This solution scales production profile of different wells and collapses them into a single general curve. The curve will later serve as the "learning" function for physic-based machine-learning...

... Furui et al. (2012) presented numerical simulation results for stress changes in overburden and production intervals for a highly compacting sandstone reservoir using a 3D nonlinear FEM model. Their simulation results clearly indicate that lithological anomalies in the caprock interval play...

... and chemically enhanced compaction, which all can affect hydrocarbon transportation. In particular, chalks (Ekofisk, Valhall) are highly sensitive to the composition of the injected brine (typically modified seawater) as demonstrated on lab and field scale. We present numerical and analytical solutions...

The currently established empirical effective stress-based pore pressure prediction is dissected to reveal its pitfalls especially regarding its application to DSCM. Compaction mechanism assumptions are also revisited in depth. Three wells from a deepwater...

Compact tests using CMS-300 equipment and pore volume compressibility tests were performed on more than 100 core plugs taking from upper Cenomanian Sarvak formation (equivalent to Mishrif formation). This formation is mainly a non-vuggy and non-fractured carbonate reservoir rock. The tests have been...

The actual reservoir data...

.... It is, therefore, doubtful that shale is ever completely void of water in typical drilling environment. Prior to drilling, the exact amount of bound and free water in shales buried at depth, however, depends on the past compaction history. Abstract This paper presents main results of a shale stability study...
