Hydrocarbon of source rocks evaluation study of Lokichar Basin, Northwestern Kenya

摘要

The hydrocarbon potential of the sub-surface Tertiary sedimentary rock sequences of the Lokichar basin system (NW-Kenya) has been interpreted using some selective geochemical analysis of rock samples in Loperot-1 Well (denoted as LT-1 Well) for their total organic carbon (TOC) which forms the premise of this study. Understanding the sub-surface structures and depositional environments conducive for hydrocarbon generation and trapping is essential as it forms the basis for exploration. The organic matter richness and degree of thermal alteration and/or maturation are factors useful in evaluating the potential source rocks. Rock-Eval pyrolysis has been employed on selected rock samples with high TOC for quantification of data and this would help in precise identification of phases of hydrocarbon generation.
