H-Index
Rankings
World Scientists H-Index Engineering & Technology / Petroleum Engineering Rankings 2025
The "AD Scientific Index" analyses the academic work of scientists using the H-index, i10 index and number of citations, and provides results that can be used to evaluate the productivity and efficiency of individuals and institutions. In addition to ranking according to "total H-index" for individuals and institutions, you can also see the ranking and analyses according to "Scientists Last 6 years H-index"and Subject Rankings.
