Paper presented at the SPE Europec, December 1–3, 2020
Paper Number: SPE-200568-MS
... History matching is a way of reducing uncertainties in the input variables of a reservoir model. History matching uses historical production data of a field to determine the reservoir properties that cannot be measured. History matching is achieved by tuning the reservoir properties to eliminate...

... Multiwell deconvolution solves this problem, by deriving (1) constant-rate derivative responses of individual wells as if they were producing alone; and (2) interference effects from any one well to any other, with the same durations as the pressure histories. Multiwell deconvolution is a new...

...) workflow which is based on the mathematical procedure of multiwell deconvolution (MDCV). MDCV trains the correlation between bottom-hole pressure (BHP) variations from PDG data records and rates variations from daily production history of a given well and other wells around it. This provides a robust...
