Therefore, in the topic of doctoral research in the field of hydrogeology / environmental geology (also related to oil and gas), I propose the following research topic: Improving the process of managing the risk of environmental degradation (including the issue of negative effects in the field of hydrogeology / environmental geology) occurring during construction or the expansion and use of crude oil and / or natural gas production installations (possibly including crude oil refining installations). As part of this topic, it is possible to precisely define and define measures for a quantitative analysis of risk factors for environmental degradation in the context of a specific environmental policy in a given country or region. In addition, within this topic, it is possible to build a universal analytical model, multi-indicator, multi-factor, which would be used to conduct the process of managing the risk of environmental degradation in the construction, expansion and use of crude oil and / or natural gas production installations. Risk factors may include issues related to local climatic and environmental conditions, their impact on the issue of surface, supernatural and groundwater, the impact of mining installations on the state of watercourses of groundwater and deepwater, etc. This topic may also include an analysis of the improvement process managing the risk of environmental degradation in the construction, expansion and use of oil and / or natural gas extraction installations by using modern ICT information technologies, i.e. improving the computerized management process of this risk category.
I suggest that there be a link between the risks of surface environmental pollution and its impact on the quality of groundwater reservoirs by calculating the value of groundwater and drawing a basic risk map for the study area.
You may identify an aquifer under the threat of depletion or contamination and research on how to mitigate the threats. This may be deep aquifers or shallow aquifers in the locality of interest. If you have TDS data of the local wells for the past ten or so years, you may propose to take the readings afresh today..in your study then undertake ANALYSIS of VARIANCE..if significantly different from previous readings,you may say your hypothesis of threat is justified....this is just an example..hop u now have a picture
What are you know and have experience (methods)? What is your geophysical level. Are you have a superviser? Which university are you going to apply for PhD ? What is your MSc topic? As I know there are no qualified geophysicists in Nigeria. If there are why he does not recommends you a topic?
