Reservoir heterogeneity of Agbada Formation sandstone from PZ-2 well and PZ-4 well, Niger Delta: implications for reservoir management

Article scientifique 2018 Anglais

Résumé

Sandstones of the Agbada Formation deposited in Eocene serves as the main hydrocarbon reservoirs of the Niger Delta Basin. PZ-2 well and PZ-4 well that penetrated sections of the formation were investigated for their reservoir heterogeneity, to understand the hydraulic flow units and better assessment of the reservoirs. Reservoir quality and pore throat sizes encountered in the sandstones vary from poor to excellent quality and macroscopic. Greater heterogeneities permeability and homogeneous porosity distribution occur in the bioturbated sandstone facies in the PZ-4 well and sandstone facies in the PZ-2 well. Four hydraulic flow units (FZ-1, FZ-2, FZ-3, FZ-4) and three hydraulic flow units (FZ-1, FZ-2, FZ-3) were recognized in the PZ-2 and PZ-4 wells respectively. These flow zones are characterised by good reservoir qualities and adjudged as a better reservoir candidate for probable prospects.
