CHARACTERISTICS OF POLLUTED SANDS A CASE STUDY IN NIGER DELTA (REVIEW)
ABSTRACTThis study is aimed at using the characteristics of polluted soil to delineate different soillayers and deduce ways of providing remediation to the problems generated as aresult of soil pollution using Electrical Resistivity Method.An inversion of the measured apparent resistivity values using a computer program was carriedout to determine the true subsurface resistivity. This method was used toestimate the lateral and vertical extend to which a particular soil has beencontaminated by...
SEISMIC TIME-LAPSE RESERVOIR MONITORING
Time lapse seismic which geophysicists often abbreviate to four dimensional (4-D) seismic is a geophysical technique which involves simply repeating a series of 3-D seismic survey over time such that the fourth dimension is in “Calendar Time”. This gives it the ability to image fluid flow in a well volume.
FIBRE OPTIC IN RESERVOIR SENSING
line-height:107%;font-family:" verdana",sans-serif"="">Fibre optic technologies came out of military and space research and development programme. Until recently, glass chemistry and laser interrogation hardware have not been at a level of robust where systems could survive in down-hole environments for long periods. Because of the physical properties, glass can thrive as a sensor at extremely high temperatures and efficiently high temperatures and efficiently transmit large quantities of da...
SEISMIC CHRONOSTRATIGRAPHY: PROSPECTS IN PETROLEUM EXPLORATION
line-height:107%;font-family:" tahoma",sans-serif"="">Seismic survey has long become a trusted tool for hydrocarbon exploration. This is because of the outstanding ability of seismic reflections and their over lapping relationships to image deep and shallow subsurface structures and delineate promising structural and stratigraphic traps. These subsurface features become good prospecting targets, maybe because of their depositional history or post depositional events. With this in mind, it is...
Forensic Geophysics: Geophysical Techniques and Applications
line-height:115%">Forensic geophysics can be seen as that involving the use of geophysical methods in the search, locating and mapping of hidden or buried features underground or underwater. Geophysical methods have the potential to aid the search and recovery of a target because they can nondestructively and rapidly investigate large areas where a suspect, illegal burial or, in general, a forensic target or object is hidden in the subsurface.
REPORT ON GEOPHYSICAL SURVEYS AT IKOT NAKANDA, AKPABUYO LOCAL GOVERNMENT AREA OF CROSS RIVER STATE, NIGERIA
Geophysical field school is an annual academic camping exercise that is aimed at exposing students to the practical aspects of geophysics. It is a three (3) credit hour course for third year students of applied geophysics aimed at educating students on the handling of geophysical equipment and the rudiments of data acquisition, processing and interpretation. line-height:107%;font-family:" tahoma",sans-serif"="">This year’s field school was held at Ikot Nakanda and i...

WASTES AND SEWAGE AS A SOURCE OF ELECTRICITY GENERATION
justify;line-height:200%"> font-family:" tahoma",sans-serif"="">ABSTRACT justify;line-height:200%"> font-family:" tahoma",sans-serif"="">Waste and residuals are undeniably part of the human society. The accumulation of these materials and the “throw away” philosophy results in many environmental and health issues and safety hazard problems prevent sustainable development in terms of resource recovery and recycling of waste materials. The carbon sources in the waste can be converted to en...
EARTHQUAKE MONITORING AND SENSING IN NIGERIA
ABSTRACTThis study reviews earthquake monitoring and sensing in Nigeria. The techniques used to monitor earthquakes include seismic, Global position system (GPS) and remote sensingmethods. For now there is no scientific method of predicting earthquakes, butseismologists depend on the anomalous animal behaviour, radon emissions,trends, creep fault, drop/rise in the water level and anomalous plant behaviourfor earthquake prediction. The study also revealed that Nigeria is not seismicallyfree fr...
APPLICATION OF GIS AND REMOTE SENSING IN SPATIAL LOCATION OF OIL AND GAS PLATFORMS IN THE NIGER DELTA
ABSTRACT line-height:107%;mso-no-proof:yes">This study investigated the uses of GIS and Remote Sensing as a strategic tool for locating the positions of oil and gas fields. It has revealed the ability of GIS tool to develop database showing all the layers used for the study from logical to physical database design, bringing to the public domain, the applications of GIS and RS technologies using geospatial data in locating oil and gas platforms in the Niger Delta and in Akwa Ibom State. This...
Analysis of the Causes of Road Failure in some parts of Nigeria (A Review)
ABSTRACTThis research assesses the various factors responsible for road failures in thesouthwestern and south-southern parts of Nigeria with the aim of reportingfindings to the public domain. The research further stressed the importance andrelevance of geophysics in evaluating civil engineering structures such asroads. The above goals were met by studying the results of surveys carried outby researchers in southern Nigeria. Electrical Resistivity and Electromagneticmethods have been used to e...
