Criteria of steam-channeling construction methods for different sample sets.

TypesCriteriaNumber of samples

Base setFind the steam-channeling time from the report and calculate the steam-channeling speed using Equation (3). Finally, the degree of steam channeling is normalized in a range of .862
Reconstruction set(1) Steam channeling and the neighboring injector are given, but the degree of steam channeling with the corresponding ranking cannot be quantitatively evaluated.128
(2) The cyclic steam-channeling data is missing in the report.
(3) The data in the report is wrong.
Prediction setBased on geological parameters and dynamic production data, the possibility of steam channeling is predicted.10
