A Quick Method To Determine Subsidence, Reservoir Compaction, and In-Situ Stress Induced by Reservoir Depletion

Abstract: Summary This paper provides a quick method to determine subsidence, compaction, and in-situ stress induced by pore-pressure change. The method is useful for a reservoir whose Young's modulus is less than 20% or greater than 150% of the Young's modulus of the surrounding formation (where the conventional uniaxial strain assumption may not hold). In this work, a parameter study was conducted to find groups of parameters controlling the in-situ stress, subsidence, and compaction. These parameter… Show more

“…-Reservoir stress path, i.e. how rock stresses change as a result of production associated processes like depletion and enhanced recovery operations (Teufel et al, 1991;Addis, 1997;Morita et al, 1989). The stress path controls to what extent the reservoir deforms elastically, or if some kind of rock failure may occur during production.…”

“…The Finite Element Method (FEM) has been applied to this problem by e.g. KOSLOFF et al (1980);MORITA et al (1989);BRIGNOLI et al (1997);GAMBOLATI et al (1999;MULDERS (2003).…”

“…Others extended Geertsma's nucleus-of-strain concept to layered subsurface (Fares & Li, 1998;Fokker & Orlic, 2006;Wang et al, 2006;Vasco et al, 2010), possibly with viscoelastic layers. The limitation of horizontal layers could be abandoned using finite-element approaches instead of influence functions (Morita et al, 1989;Teatini et al, 2011;Orlic & Wassing, 2013;Marketos et al, 2015Marketos et al, , 2016. Finite-element calculations are not based on the nucleus-of-strain concept but employ a fully numerical approach.…”
