A dynamic monitoring system for dynamically monitoring injection operations on wells by determining the extent of fracturing using downhole pressure measurements. The system comprises a downhole pressure gauge 14, means 16 to transmit data from the downhole pressure gauge to surface and a surface data acquisition unit 20 wherein, on inducing a pressure change in a wellbore by an injection operation, the downhole pressure gauge records a pressure trace as data, the data is transmitted to surface at a first sampling frequency, the data is stored in the surface data acquisition unit and fracture length is calculated from the stored data to indicate extent of fracturing. |
