The Effect of Oil Saturation On the Mechanism of Compaction In Granular Materials: Higher Oil Saturations Lead To More Grain Fracturing and Less Pressure Solution

Abstract: Whether addition of oil to sandstones slows, stops, or has no influence upon pressure solution and quartz cementation has long been disputed, despite having major implications for petroleum exploration and appraisal strategies. To elucidate the effect of addition of oil to compaction, pressure solution, and cementation processes, this study utilizes an experimental approach simulating isochemical, volumetric compaction using granular halite in the presence of variable brineoil mixtures. Each experiment, at 500… Show more

“…There are a variety of ways to speed up processes, including using higher temperatures than found in diagenetic systems; an example of this are routine rock-eval pyrolysis measurements of source rock maturity and richness (Hunt 1995), simulation of dolomitization (Kaczmarek & Sibley 2011) and measurements of the rate of redox reactions during thermochemical sulphate reduction (Cross et al 2004). Reaction rates can also be increased by using analogue materials that are more soluble than silicates or carbonates (Sathar et al 2012) and fluid compositions that are exceptionally far from equilibrium with the host rock (Heald & Renton 1966;Chermak & Rimstidt 1990;Lander et al 2008a).…”

“…The question of the role of petroleum emplacement on sandstone diagenesis (and the possible preservation of porosity) has fired up much excitement with numerous papers seeking to address the problem from a combination of theoretical, oil-field data and experimental approaches (Marchand et al 2001;Bloch et al 2002;Taylor et al 2010;Sathar et al 2012;Wells et al 2015). Some have concluded that petroleum emplacement has no influence on sandstone diagenesis (Taylor et al 2010).…”

“…Field-based (Marchand et al, 2002) and experimental (Sathar et al, 2012) studies have shown that quartz cementation is inhibited at high oil saturations. However, other studies (e.g Aase and Walderhaug, 2005;Molenaar et al, 2008;Saigal et al, 1992) have suggested that there is no correlation between hydrocarbon emplacement and porosity preservation.…”

“…Factors such as the presence of clay mineral coats or microcrystalline quartz coats, early emplacement of hydrocarbon, presence of salt‐related thermal anomalies, mineral dissolution and fluid overpressures can all play a crucial role in preserving anomalous high porosity in sandstones (e.g. Spotl et al ., ; Worden and Morad, ; Taylor et al ., ; Wilkinson and Haszeldine, ; Sathar et al ., ; Nguyen et al ., ). Fluid overpressure, defined as the excess pore pressure above the hydrostatic pressure for a given depth, is commonly encountered in deep High Pressure High Temperature (HPHT) reservoirs (Osborne and Swarbrick, ).…”
