[ What is claimed is:] [1.]1. A method of monitoring a particular wellbore operation, comprising:(a) providing a wellbore tubular string;(b) providing a plurality of discrete and individually actuable wellbore tools;(c) providing at least one receiver communicatively coupled to at least one of said plurality of discrete and individually actuable wellbore tools for selectively actuating at least a particular one of said plurality of discrete and individually actuable wellbore tools upon receipt of a particular command signal;(d) providing at least one subsurface transmitter;(e) providing at least one subsurface processor;(f) providing at least one subsurface sensor for sensing at least one subsurface condition, which is communicatively coupled to said at least one subsurface processor;(g) securing said plurality of discrete and individually actuable wellbore tools, said at least one subsurface transmitter, said at least one subsurface processor, and said at least one subsurface sensor in particular and predetermined locations within said wellbore tubular string;(h) lowering said wellbore tubular string into said wellbore;(i) transmitting at least one command signal into said wellbore;(j) utilizing said at least one receiver to detect said at least one command signal, and to individually actuate at least one particular one of said plurality of discrete and individually actuable wellbore tools which is associated with said at least one command signal;(k) utilizing said at least one subsurface sensor to monitor at least one subsurface wellbore condition;(l) utilizing said at least one subsurface controller to receive data from said at least one subsurface sensor and to process said data in a predetermined manner including at least the performance of at least one frequency domain analysis on said data; and(m) utilizing said at least one subsurface transmitter to communicate information relating to said data to a remote location.
