The development plan includes the placement of injection and monitoring wells, conceptual design of injection wells and monitoring wells, and conceptual risk management plan and monitoring planning. In this paper, we describe the conceptual design process, summarizes the key...

... ABSTRACT: Weakly consolidated sandstone reservoirs generally feature poor cementation, low strength, relatively high porosity and high permeability. Due to the significant effect of poroelasticity, stress redistribution resulting from the pore pressure perturbation around the injection well...

... ABSTRACT: Seismic response to fluid injection at the Húsmúli area within the Hellisheiði geothermal field in Iceland was investigated by correlating induced seismicity with fault structures and fluid injection rates. Induced seismicity recorded around five injection wells over a half-year...

What if it were possible to control hydraulic fracture extents more directly than these methods do and to have confirmation of these extents in the subsurface? For this, we propose a ‘fracture caging’ concept where...
