An integrated approach of rock physics and Geomechanical analyses was adopted in this study to enhance the prediction of sanding in oil wells within ‘CHI’ field offshore Niger Delta. The data used for this study include suite of wireline logs from three wells, base map and checks...
Thirty (30) shale core samples from the Agbada and Akata formations in the Niger Delta, Nigeria were evaluated using a Rock-Eval pyrolysis to determine their richness, type, thermal maturity and hydrocarbon potential. Agbada and Akata formation samples show fair to Excellent cont...
Twelve (12) vertical electrical sounding were obtained in parts of Lagos State. Nineteen (19) deep boreholes within the Dahomey basin using resistivity and natural gamma ray wirelogs data were obtained. The vertical electrical sounding obtained were interpreted by WIN resist soft...
Geologic structures that aids the accumulation of hydrocarbon in reservoirs could be fault assisted or fault dependent, these faults can be described as sealing or leaking in nature. In this study, well logs and 3D seismic data were utilized for the seal integrity analysis in Son...
The study assesses the thermal maturity levels of crude oils from the Niger Delta Basin of Nigeria using biomarker fingerprinting technique. Thirteen (13) crude oil samples were deasphaltened by the addition of n-heptane. The maltene fractions were analysed using the Gas Chromato...
Subsidence history and hydrocarbon maturation studies was analysed using well log data from four adjacent fields from the eastern part of Niger Delta basin. Three major tectonic phases of the basin evolution were identified as, firstly, a phase of subsidence from the mid to early...
A new species, postfossulatus, was originally described by Sirel and Deveciler in the middle Lutetian sediments in the Haymana region (Central Anatolia, Central Turkey). The main purpose of this research is to reveal the new locations and new stratigraphic level of the new specie...
Road pavement failure observed along a section of Apete-Akufo Major Road in Ibadan metropolis southwestern Nigeria, necessitates the need to ascertain whether the failure results from poor construction practices or poor engineering properties of subgrade materials. Geophysical an...

The ecological health of River Kafin Hausa was assessed in three well marked out stations for a period of four (4) months, spanning from January to April, 2018. Water samples were collected at each sampling site and analysed according to approved standard. The habitat quality eva...
Tanzania has abundant natural resources potential to provide means for inclusive and sustainable private sector development. This paper assesses levels of risks and impact of Covid-19 on the private sector production systems, employment and commodity prices in the extractive sect...
