Palynofacies and Environment of Deposition of HA-001 Well, Shallow offshore Western Niger Delta Basin, Nigeria

Abstract

Palynofacies analysis of sedimentary intervals in HA-001 well was carried out on seventy-five (75) ditch cutting samples collected from western Niger Delta, Nigeria with the aim of establishing the palynofacies and environment of deposition interpretations of the studied sections. Palynofacies analysis showed the dominance of land phytoclast, amorphous matter and miospores over marine palynomorphs. Palynomacerals I and II were abundant while Palynomacerals III and IV gave few occurrences. The paleoenvironmental interpretation of the studied well intervals using the ternary plot diagram of kerogen indicated deposition in distal dysoxic-anoxic shelf. This plot showed that HA-001 well is prone to optimum petroleum generation.
