Using image logs from horizontal wells in the asymmetric East Painter Reservoir anticline Wyoming, scanlines and petrographic observations nearby outcrops, methods that allow statistical quantification of fracture spatial arrangement patterns (including clustering), we show early Jurassic Nugget Formation sandstone degree clustering intensity fractures varies with structural position. In backlimb, are markedly more clustered than random, hierarchical regularly spaced clusters present, but is low. forelimb, arrangements mostly indistinguishable high. Based on log response, backlimb contains a higher proportion open fractures, although forelimb has greater numbers fractures. Spatial similar outcrop. Petrography reveals quartz seals less 0.15 mm wide. Wider rinds or lined sealed calcite filled by quartzose cataclasite. The depends deposits closure reactivation (shearing) pre-existing quartz-lined increased abundance strike dispersion, results suggest forelimbs, high intensities reflect shear preexisting possibly resulting numerous spatially correlated most prolific gas water production suggesting sparse effective fluid conduits closely partly damaged/sheared arrays.

Fracture-pattern growth in the deep, chemically reactive subsurface

Arrays of natural opening-mode fractures show systematic patterns in size and spatial arrangement. The controls on these factors are enigmatic, but many cases the depth formation appears to be critical. Physical, potentially depth-dependent that could account for variations include confining stress, fluid pressure, strain rate; common inputs existing fracture models. However, temperature-dependent chemical processes likely exert an equally important control patterns, such have not yet been rigorously incorporated into models formation. Here we present a spring-lattice model simulates fracturing extending sedimentary rock beds, while explicitly accounting cementation during opening fractures, failure via both elastic time-dependent criteria. Results illustrate three distinct behaviors having documented analogs, which here term facies. "Exclusionary macrofracturing" occurs at shallow levels produces large, widely spaced, uncemented fractures; "multi-scale fracturing" moderate partially cemented wide range sizes spacings; "penetrative microfracturing" great myriad narrow, sealed closely regularly spaced. effect is primarily accelerate dissolution precipitation reactions increased temperature porewater salinity; specific each facies will vary by host-rock lithology, grain size, rate, thermal history.
