Electrical resistivity and conductivity

Geophysical investigation has been conducted using resistivity survey along Angalakiri Creek, Okuntu road, Ogulaha area in Burutu Local Government Area (L.G.A) of Delta State, Nigeria with the aim of investigating the lateral and vertical spread of hydrocarbon spilled into the Angalakiri creek along Okuntu road and buried by the banks of the creek during the clean up of the floating hydrocarbon. The 2D resistivity imaging technique using the dipole- dipole array method was adopted for the survey with the aid of the SAS 4000 Terrameter. The inferred lithology from 2D resistivity inversion are topsoil, clayey sand and sand. The study delineated resistivity values ranging from 74 Ωm to 5010 Ωm. The high resistivity values (800 Ωm - 5100 m) are as a result of the buried crude observed in all the profiles except profile 6 which was located outside the polluted area. This study has revealed that the buried hydrocarbon has not degraded and has spread laterally along the Angalakiri with vertical penetration of penet...
