Single Well In-Situ Permeability Assessment to Deduce Hydraulic Conductivity of Aquifer at Gio, Gokana Local Government Area, Rivers State, Nigeria

Abstract

The impact of oil spill incidences in the Niger Delta States of Nigeria is real. Mitigation efforts are hindered by data gaps. One of such disparities is occasioned by inappropriate methods used in determining the hydraulic conductivity of the aquifer underlying a spill site. Hence, this study demonstrates the application of single well in situ permeability test to determine the hydraulic conductivity of an aquifer at a site in Gio, Gokana LGA of Rivers State, Nigeria. The field pumping test was conducted using standard methods. Hydraulic conductivity values were between the limits of  0.89  and 48.2 meters per day. The results agreed with the aquifer texture in Gio site that was dorminantly coarse, well sorted sand and conformed with Darcy’s rule, that permeability is dependent on hydraulic gradient
