WebTricyclic terpanes are a class of hydrocarbons with three fused 6-carbon rings and an alkyl side chain. The C 19 to C 29 tricyclic terpanes are commonly observed in crude oils and source rock extracts, with the higher members (up to C 54) obscured by the abundance of hopanes in the m/z 191 mass chromatogram [20] and [21].
WebPyrolysis, chromatographic, and isotopic techniques were applied to study a suite of (174) rock cuttings from Muglad’s block 2 & 4, aiming at identifying and fully characterizing the potential source rock/s in the basin. Two source rock units were recognized and de WebThe distribution of terpanes shows small amounts of tricyclic and tetracyclic terpanes in most of the samples (except for some Cretaceous samples) and a predominance of pentacyclic terpanes. The amount of 17α (H),22,29,30-trisnorhopane (Tm) usually exceeds the amount of 18α (H),22,29,30-trinorneohopane (Ts).
