... the constant cement model works for weakly quartzcemented sandstones (Dutta, 2009) with less than 5% cementation (Avesth et al., 2009; Avesth et al., 2011; Drude et al., 2013 Ganguli, 2017; and Zhang, 2018). Unfortunately, none of the above-mentioned RPMs could work well for deep, varryingly and highly...

... for the JFES 28th Annual Symposium held from September 13-14, 2023. ABSTRACT In Southern Offshore China, a deepwater sandstone reservoir with the strong bottomwater drive has been intensively produced for 12 years which was followed by a 10-year s abandonment. A redevelopment campaign designs new horizontal...

... for CO2 injection and storage have been selected through a survey by using the existing exploratory wells drilled in offshore Akita. Especially much attention has been focused on reservoir rocks consisting of sandstone and volcanic tuff. This paper focuses to tuffaceous sandstones and tuffs...

... log response from GDW sandstone was believed to be almost the same as normal sandstone which does not contain any hydrocarbon. In the recent in-fill well drilling campaign for GDW reservoir, a full suite of wireline logging was carried out. With a success of good quality data acquisition, an advanced...

Log units on seismic sections are shown in Figure 3. Because most lithology showed...

... the inversion technique is based on the poroelastic theory, poroelastic parameters of reservoir rocks (e.g., sandstone) should be well understood to increase reliability of the monitoring technique. Understanding of poroelastic parameters is also essential in a geomechanical model simulation of the geological...
