1. A method of recovering hydrocarbons from a hydrocarbon-containing reservoir comprising:
a) drilling at least one producer well;
b) drilling at least one observation well;
c) installing a plurality of sensors for distributed acoustic sensing, microseismic monitoring and a plurality of pressure gauges in each observation well;
d) obtaining, microseismic, pressure, and DAS data from said observation well to form a pre-stimulation data set;
e) while fracturing at least one producer well in a first fracture stimulation stage according to pre-determine fracturing parameters to form a set of fractures;
f) obtaining, microseismic, pressure and DAS data from said observation well to form a stimulation data set;
g) identifying said set of fractures formed in said fracturing step by comparing said pre-stimulation data set and post-stimulation data; wherein formation deformation is mechanically coupled with strain rate during hydraulic fracturing and formation compression through stress shadowing;
h) characterizing the complexity of said set of fractures;
i) updating said pre-determined fracturing parameters based on said characterizing step;
j) performing a second fracturing stimulation stage; and,
k) producing hydrocarbons.
