1. A system for evaluating cross-well interference in a hydrocarbon reservoir, comprising:
a) a hydraulically fractured monitor well in a hydrocarbon reservoir;
b) a hydraulically fractured production well fitted for production of hydrocarbons in said reservoir;
c) one or more fiber optic cables along a length of said monitor well, said one or more fiber optic cables configured for low frequency distributed acoustic sensing (“DAS”) of <1 Hz and for distributed temperature sensing (“DTS”);
d) one or more pressure sensor(s) in said monitor well and in said production well;
e) a processor at a surface of said reservoir operably connected to said one or more fiber optic cables and said one or more pressure sensor(s) for analyzing recorded DAS data and DTS data and pressure data.
