ABSTRACT This work assessed the combine effect of wood ash and lime on the geotechnical properties of expansive soils. The wood ash used was a waste product from bakery industry while the lime was of industrial grade. The soil was sampled from the location of the study area where engineering structures have been damaged by the expansive soil that underlain the area. The chemical composition of the wood ash and ...

ABSTRACT Facies geometry, stratigraphic configuration, structural style, hydrocarbon  type and distribution within the paralic Agbada Formation of Middle to Late Miocene age across several fields in the Eastern part of the Coastal Swamp depo-belt were studied using regional 3D seismic,  wire-line well  logs  and  biostratigraphic   data.  The  study  involved  analyses  of sequence  stratigraphic framework  across nine fields using information  obtained  from twenty-  four wells. Ten major stratigraphic bounding surfaces (five ...

ABSTRACT This project addresses the effects of increase in fines contents on the geotechnical properties of sandy soils and the roles the fines play in slope instability in Nsukka,  Enugu  state in Nigeria. Field investigation revealed that the major landslides and gully erosion sites in south eastern Nigeria are localized within areas where these sandy soils are present. Geotechnical investigation of these sandy soils was carried out to assess their ...

ABSTRACT A  shallow geophysical investigation for  road surface  failure  using  2D  electrical  resistivity imaging profiling was conducted to produce an approximate model of the subsurface resistivity. This study was done with the aim of revealing the horizontal and vertical geological discontinuities using electrical resistivity, an intrinsic property of all materials. Probable zones of untimely failure along the road are then investigated by variation in resistivity. Four traverses were established on ...

ABSTRACT An integrated geological, geoelectrical and hydrogeochemical investigations were carried out in Eha-amufu to determine the extent and the distribution of saline zone. Hydrochemical characteristic of the groundwater in Eha-amufu was investigated.  Eha-amufu area is underlain by Nkporo Formation and Awgu Formation. Both are of low permeability Formation. Twenty seven (27) Vertical Electrical Sounding (VES) were occupied at different locations within the study area, employing the Schlumberger electrode configuration with ...

ABSTRACTThe Niger Delta is located on a typical passive margin withsediment thicknessesin excess of 12 km at the basin center. The combinedoccurrence of rift structures, basin subsidence, rapid progradation of deltaicsystems, development of growth faults and fold thrust belts in the offshoreNiger Delta produced a very unique petroleum habitat with different structuralstyles and play types. Most of the prospects and producing fields in the regionare related to faulted structures. Structural ...

ABSTRACT In the Buntsandstein gas fields of the Southern North Sea, the Volpriehausen reservoir is the main producing unit. This reservoir suffers often from the in-filling of the reservoir pore spaces by solid materials (salt plugs). Determining the reservoir quality of these fields based on seismic data alone has proved to be a major exploration challenge; the presence of salt-plugs in reservoir pore spaces seems to produce seismic responses that ...

ABSTRACT Petrophysical  evaluation  and  3D  seismic  interpretation  were  carried  out  on  the hydrocarbon bearing reservoirs of Stroh field with the aim of maximizing the benefits of  petrophysical   evaluation  and  structural  interpretation  in  the   production  and development of hydrocarbon in the reservoir of the ‘Stroh field’ in Niger Delta. Eight hydrocarbon bearing reservoirs – sands ST1, ST3, ST6, ST7, ST8, ST11, ST13 and ST14 were identified from well logs and correlated ...

ABSTRACT The proliferation  of abandoned  surface  excavations  in the Benue  Rift  not only contributes  to land degradation  and landscape disruption but also results in loss of economic deposits,  dearth of mining data and generation of unprotected  spoils with known potential to contaminate  ground and surface water sources.  This study employed field description and measurements, laboratory testing and numerical simulation techniques to evaluate some derelict barite fields in the rift with ...

Abstract This study is a contribution to the understanding  of the depositional environment and reservoir architecture of the "JI  Field", Niger Delta Nigeria.  The main objective  was to integrate sequence stratigraphy and petrophysical  evaluation  in characterizing  the reservoirs  encountered in the wells.  Well logs from six wells (JI01, Il02,  Il03,  Il09, Jll0  and  1112-ST),  biostratigraphic  data  from  two  wells  (JI01  and  Il02)  and  3D seismic volume were analyzed to understand ...

ABSTRACT A questionnaire and observational study were randomly conducted on 204 houses to acquire information  on  different  sewage  disposal  methods  used  in  Enugu  metropolis,  and  to investigate  the impact  of the sewage  disposal  methods  on  available  water  supplies.  The results obtained show that 51% of the resident’s wells are located at a distance less than 9m from the toilets. Samples from 21 different locations in the area were analyzed and ...

ABSTRACT Reservoir characterization has taken prominence in hydrocarbon exploration due to its role in proper  understanding  of  the  reservoir  properties  such  as  lithofacies,  and  petrophysical parameters, to enhance success in the quantification of the hydrocarbon reserve in place thereby diminishing  exploration  failures  and  enhancing  successes.  This  research work  is  aimed  at integrating three-dimensional seismic data and petrophysical log data to characterize reservoirs of interest, map structures, delineate facies and interpret ...

ABSTRACT Cenozoic sediments outcrop in the Niger Delta Basin.  Deposits in the Basin thicken southward (down-dip) but thin northward (up-dip) around Bende    Umuahia area where approximately 260 m thick exposure was logged from base to top.  Sieve analysis and petrography were carried out to establish the depositional  settings of sediments while palynological  analysis was undertaken  in order to identify palynomorphs  and establish their biozonations,  determine and correlate age of sediments, ...

ABSTRACT Reservoir quality assessment and characterization of sandstone units was carried out across the Afikpo area of the Southern Benue Trough. The study involved field investigations and laboratory studies/analyses. Field samples were subjected to Grain Size Analysis (GSA), Sand Equivalent test and Methylene Blue test. Studies revealed that the sandstones are friable, cross-bedded and show coarsening upward motif. Results from lithofacies analysis indicate seven (7) lithofacies deposited in a low ...

ABSTRACT Detailed field based structural, fracture and paleostress analysis were carried out on Cenomanian to Maastrichtian units forming the Afikpo syncline structure. Three fracture systems were isolated from analysis of fracture orientations and thier field relationships: Pre-folding (JT), Syn-Folding (JS) and Post Folding (JC) fracture systems. Paleostress analysis carried out on these fracture systems using the TENSOR™ software tool (Delvaux & Sperner, 2003) yielded three paleostress tensors corresponding to three ...
