Method of and apparatus for determining a multiple well seismic-to-well tie

A method for determining a seismic-to-well tie for a plurality of wells comprised within a reservoir zone, the method comprising:

• a) obtaining a trained neural network, having been trained to infer well data from seismic data for said reservoir zone;
• b) generating a first candidate population of well locations for each of said plurality of wells;
• c) using said trained neural network to invert seismic data relating to said reservoir zone in accordance with said candidate population of well locations, to obtain inversion well data;
• d) evaluating said inversion well data by comparing said inversion well data to validation well data relating to the reservoir zone;
• e) applying an evolutionary algorithm to said candidate population of well locations to obtain an updated candidate population of well locations;
• f) further training said trained neural network in accordance with said updated candidate population of well locations;
• and
• g) iteratively repeating steps c) to f) until at least one stopping criterion is reached;
• the method further comprising:
• using the neural network trained at a final iteration to perform an inversion on further seismic data relating to said reservoir zone to obtain further well data relating to said reservoir zone;
• and
• optimizing a production strategy to produce hydrocarbon from said reservoir zone based on said further well data, the optimization of the production strategy comprising selecting from and/or optimizing one or more of different well placements, different number of wells, different injection fluid pressures, different injection strategies, or different injection fluids and/or drilling used.
