Geomechanical restoration as a tool for fractured reservoir characterization: Application to the Permian Basin, west Texas

Natural Fractures in Low-Permeability Sandstone Reservoirs in the LD-A HPHT Gas Field, Yinggehai Basin: Implications for Hydrocarbon Exploration and Development

“…Quantitative characterization methods of multiscale natural fractures based on outcrops, cores, thin sections, SEM, and CT were established (Fall et al, 2015;Zeng et al, 2022). Natural fractures were identified and evaluated using logging and drilling data with production performance data (Ezati et al, 2018;Fernández-Ibáez et al, 2018;Stockmeyer et al, 2018), and methods including the curvature method, geomechanical simulation, and geophysical methods have been proposed (Olson et al, 2009;Yin et al, 2016;Hooker et al, 2018;Gong et al, 2021). Additionally, the fracture effectiveness and influencing factors are investigated to analyze the effects of fractures on fluid flow (Alghalandis et al, 2015).…”

Validating novel boundary conditions for three-dimensional mechanics-based restoration: An extensional sandbox model example

“…Structural restoration is a valuable tool to investigate the geometries of geological structures through time, assess the validity of structural interpretations, and analyze strain elds (e.g., Chamberlin, 1910;Dahlstrom, 1969;Gratier et al, 1991;Léger et al, 1997;Williams et al, 1997;Rouby et al, 2002;Griths et al, 2002;Dunbar and Cook, 2003;Muron, 2005;Groshong, 2006;Maerten and Maerten, 2006;Moretti, 2008;Durand-Riard et al, 2010, 2013bMaerten and Maerten, 2015;Stockmeyer et al, 2017). Over more than fteen years, geomechanical restoration approaches that approximate natural rock behavior have been developed to overcome several limitations of traditional geometrical restoration methods (e.g., Fletcher and Pollard, 1999;Maerten and Maerten, 2001;Santi et al, 2003;Muron, 2005;Moretti et al, 2006; Maerten to x degrees of freedom and guarantee that the solution is unique (e.g., Plesch et al, 2007;Guzofski et al, 2009;Vidal-Royo et al, 2012;Durand-Riard et al, 2013a,b;Stockmeyer et al, 2017).…”

“…This uncertainty in appropriate boundary conditions is particularly problematic if one intends to analyze the corresponding stress or strain for fracture analysis or other purposes (Maerten and Maerten, 2006;Mejía-Herrera et al, 2014;Stockmeyer et al, 2017). The problems illustrated by Lovely et al (2012) are: (1) there may be instances when the classical boundary conditions, as dened above, may be unphysical and (2) there is no specic guideline to choose appropriate boundary conditions in restoration.…”
