Abstract: 
Some changes in values of vegetation indices for the red edge position (REP) and MERIS terrestrial chlorophyll index (TCI) affected by natural gas leakage are investigated. The study is made on the basis of the field survey of wheat crops over the Hlibovske gas field (Crimea) and beyond its bounders from 27 May to 29 May 2010 which was aimed to reveal gas searching indices. Some decrease in REP and TCI values over the gas field relative to their mean ones beyond the gas field bounders is found and some strong correlation between REP and TCI with r = 0.987 is detected. This testifies that the TCI is potentially one of the gas searching indices.
