Specific type of Production Analysis (PA) workflow based on correlation between multi-well production/injection history and permanent downhole gauges (PDG) data records.
The key engine of MRT is pressure convolution which is based on unit-rate transient responses retrieved from Production rates / PDG data history by means of pressure deconvolution.
It does not require new data acquisition at well site and makes use of existing dynamic data records.
The ultimate purpose of MRT is to extract maximum information from correlation between the flowrate and BHP history.
This information is further related to well flow performance and cross-well connectivity.
