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...
In Islamabad (Pakistan), surface water and groundwater extract water from shallow alluvial sediments are the sources of water supply. The direct research on hydrogeological conditions in Islamabad, carried out in 2020, included chosen hydrogeological field studies, physicochemica...
Detailed down-dip, bed-by-bed sedimentary logging of outcrops of the Ameki Group in the Awka-Onitsha area of south-eastern Nigeria, was performed to identify and characterize components of the Group in the area. Thirteen exposures were measured and analyzed for lithological chang...
The Wadi Masilah Basin is part of the larger Say’un-Masilah Basin, a Mesozoic sedimentary basin located in the southeastern Yemen. It consists of a sedimentary sequence hosting polymetallic barite, lead, zinc, iron, manganese, and vanadium mineralisations. The area is strongly fa...
A combination of Shuttle Radar Topographic Mission (SRTM) Digital Elevation Model (DEM) and electrical resistivity were applied in parts of Minna, Sheet 164 SW, North-Central Nigeria to delineate favourable sites for drilling boreholes. Lineaments were extracted from derivative m...
Badr EI-Din 1 (BED-1) field is one of the most prolific areas in the Western Desert and is a part of Badr EI-Din Concession, 300 km west of Cairo, and to the west of Abu Gharadig Field. The available open hole well records contain complete logs in the form of composite (Gamma-Ray...
The debate on sustainable use of natural resources, population growth, the role of technology in economic growth, and individual preferences have a long history, starting from Malthus’s noble argument on biophysical limits to growth to ecological economist’s sustainable developme...
Some clay soil samples from the Buan in parts of the southern Nigeria were analyzed for their geochemical composition, mineralogy and geotechnical characteristics. This research was carried out using modern methods of analysis such as Index properties tests, x-ray fluorescence an...
Petrographic study of the Eze-Aku sandstones exposed within the Afikpo basin were analysed to determine the petrography, provenance and tectonic setting of the area. Petrographic studies showed that the Eze-Aku sandstones were predominantly quartz, feldspar and lithic fragments....
