We assess the possibility of decreasing breakdown pressure rock and increasing Stimulated Reservoir Volume (SRV) by using pre-breakdown cyclic injection during hydraulic fracturing under triaxial stress conditions. Unlike monotonous increase in used conventional fracturing, fluid is injected cycles until breakdown. During peak each cycle increased increment 10% reference pressure. The at which fails injection. experiments were conducted on dry saturated Tennessee sandstone decrease SRV...
Substantial increase in the occurrence of injection-induced seismicity across Central and Eastern United States past decade, has highlighted a need for novel approaches to geophysical subsurface imaging potentially seismogenic faults. Active clusters illuminate linear fault segments within sedimentary cover crystalline basement that were unknown until began. Such surprises are due limited availability 3D seismic reflection surveys difficulty relatively shallow earthquake events from sparse...
The economic success of the relatively new STACK area Anadarko Basin Oklahoma has justified acquisition 3D seismic data volumes. One first tasks in evaluating plays for horizontal drilling is to map structure and alert drillers potential faults that can cause wells go out target formation. Much faulting basement controlled. high-quality illuminate a previously undocumented system magmatic sills range from flat upward climbing east. None these or dikes penetrate sedimentary section,...
Because of their improved leverage against ground roll and multiples, as well the ability to estimate azimuthal anisotropy, wide-azimuth 3D seismic surveys routinely now are acquired over most resource plays. For a relatively shallow target, these can be considered long offset well, containing incident angles up 45°. Unfortunately, effective use far-offset data often is compromised by noise normal moveout (NMO) (or, more accurately, prestack migration) stretch. The conventional NMO...
Zoeppritz's (1919) equations describe the partitioning of P- and S-wave energy into transmitted reflected components as a function incident angle. The three-term approximation developed by Aki Richards (1980) show that P-impedance (ZP), S-impedance (ZS), density (ρ) can be estimated from "PP" waves At near angles PP reflection is only sensitive to changes in ZP. farther angles, all three parameters, ZP, ZS, ρ. Because no converted are measured, loss resolution for inverted ZS ρ due migration...
The Mississippian-age Sooner Trend Anadarko Canadian Kingfisher (STACK) area of Oklahoma is one the more important new resource plays in North America. It consists multilevel drilling targets, including mudrock, siltstone, and carbonate reservoirs, some which are self-sourced all require hydraulic fracturing to produce commercial quantities oil. efficacy relies on whether created fracture network drains from producible rock types. We have integrated data at core seismic resolution scales map...
