Truncated Conjugate Gradient Method for History Matching in Reservoir Simulation

Resumo

History Matching (HM) is an important problem in Oil Reservoir Simulation. We present here the Truncated Conjugate Gradient (TCG) Method to solve this problem. We compare TCG with two other well known schemes, TSVD and L-BFGS, in a numerical experiment using the benchmark problem PUNQ-S3. Our results indicate that TCG is a valuable tool for HM.
