Evaluating optimal well placement in horizontal drilling using geosteering: A case study of Agbada Field, Niger Delta

  This study focuses on the use of geosteering technology in the optimal placement of wellbore path in Agbada 61 reservoir formation, where geological or subsurface target is far less than 100 m and where conventional approach could not be applicable. This was achieved by the formulation of a predrilled formation model from existing nearby or offset well by invertion of the resistivity log use in Agbada well...

A geographic information system (GIS)-based modified erosion potential method (EPM) model for evaluation of sediment production

This research is aimed to modify erosion potential method (EPM) so that its dependency reduces to engineering judgment as well as broadly watershed visit by applying geographic information System (GIS). This study was carried out within acceptance of existing structure and framework of EPM model. In EPM model, the sediment production is evaluated in terms of four parameters including soil and rock resistance to erosion,...

An application of 2D electrical resistivity tomography in geotechnical investigations of foundation defects: A case study

  The high spate of differential settling and/or sudden collapse of buildings in Lagos has necessitated a holistic approach to foundation investigation prior to the erection of such structures as a panacea to environmental and engineering tragedy of our time, which we try to address in this work. In this paper, a 2D electrical resistivity tomography (ERT) and geotechnical investigation were carried out at Ogudu...
