The challenge of balancing inversion accuracy and speed is a well-known one in well-test analysis. Two homogeneous well-test models with single- and dual-porosity media are first presented for the study. Then, a new semi-iterative model (SIM) is used for a well-test curve-matching method based on featured points of these two well-test models. This study also compares the performance of the SIM, the formula-based analytical model (FAM), and the full-iterative model (FIM). It is found that the SIM can be more efficient and accurate in inverting the parameters of homogeneous reservoirs.
Methodology
Errors in curve matching can lead to nonunique well-test interpretations.
