Owing to poor preparedness and mitigation measures for oil and gas pipeline vandalization in the Niger Delta Region of Nigeria, there have been series of spills that have now reached life threatening levels. This study set out to investigate factors that affect preparedness and mitigation measures for crude oil pipeline vandalism in the study area. The thrust of the study was to unravel the spatial variation in the preparedness and mitigation measures for crude oil pipeline in the region. The study used the survey research method and primary data was sort using questionnaire. The target population were heads of household and workers of multinational companies working in the area. Analysis of variance was used for hypotheses testing at the 0.05 level of significance. The study revealed that the companies’ preparedness options were, use of hazard, risk and vulnerability assessment (76%). Both the community (42%) and companies (76%) respondents averred that the preparedness measure adopted in the area were less effective for combating the menace of pipeline vandalism. The mitigation practices against pipeline vandalization adopted included awareness creation, promoting community participation, community policing, community-based pipeline surveillance, community by laws, right of way, punishment for offenders, and excommunication. Majority of the respondent whether community respondents (48%) or companies respondents (84%) suggested that, the adopted mitigation measures were not effective. The ANOVA model was significant at p<0.05 (F, 14 sig 0.000) meaning that there is statistical significant variation in the level of preparedness for oil and gas pipeline vandalization in the study area. Similarly, the ANOVA model that measured the spatial variation in mitigation measures showed that the model is significant at p<0.05(F, 16.83, sig 0.000), meaning there is statistical significant spatial variation in the level of disaster mitigation for oil and gas pipeline vandalization in the study area. The study recommends improvement in surveillance technology, creation of awareness of the dangers of pipeline vandalism to the locals, amongst others.

The People

Niger Delta region is very rich in oil and gas deposits, clay, agricultural land, fisheries, extensive forest and other resources. They are nine states which make the region namely, Abia, Akwa Ibom, Bayelsa, Cross River, Delta, Edo, Imo, Ondo and Rivers. The most oil producing communities among them are Akwa Ibom, Bayelsa, Edo, Delta and Rivers State. Clay is equally found in abundance in all the states like crude oil is found in Niger Delta communities. The available clay mineral in the region has the capacity to transform the nation’s economy if properly utilized. Clay is the basic material for pottery or ceramics production. It is also used to ease the penetration of pipes in drilling of crude oil. This paper looks at the practice of pottery in Niger Delta Area with a focus on pottery practice in both Akwa Ibom and Rivers States. Indigenous and contemporary pottery or ceramics practices in these communities indeed have played vital role in the economic, social religious and cultural ways of life of the people. Clay products such as dinnerware and sanitary wares and others are highly sought for and they have the capacity to boast the national economy as experienced in other nations such as Japan, Italy, Britain, United States of America, India and China among others. Data were collected from both primary and secondary sources and were subsequently assessed. The result shows that proper utilization of clay found in Niger Delta has the potential to create numerous job opportunities for the teaming population of youths in the region. The availability of abundant clay in the region, if well harnessed could adequately compete with crude oil exploitation for economic purposes in the region.

The exploration, production and refining of crude oil has led to severe environmental degradation in the oil producing communities of the Niger Delta region of Nigeria. Enhanced bioremediation of tropical rainforest soil artificially polluted with crude oil, bioaugmented with nitrogen fixing bacteria (NFB) and biostimulated with poultry droppings was carried out ex situ. Soil sample was collected at 15cm depth from tropical rainforest soil of the University of Port Harcourt, Nigeria. The NFB was isolated from roots of leguminous plant Arachis hypogea, identified as Nitrobacter species. Bioaugmentation by application of NFB served as option A, option B (biostimulation by application of poultry droppings), option C (No amendment) served as the control. Bioremediation was monitored for 28 days for interval of 14 days, and determined using the percentage ratio of total petroleum hydrocarbon (TPH) losses for each period to TPH at initial day (day zero). Results of total culturable heterotrophic bacterial (TCHB) counts showed that highest range in option B (1.9×104- 2.4×109Cfu/g) than in option A (7.8×106 -2.29×107Cfu/g) and C (6.75×106 -2.6×107Cfu/g) respectively. Similarly, hydrocarbon utilizing bacterial (HUB) counts had higher range in option B (1.20×105 - 1.9×107Cfu/g) than in option A (8.30×104 - 2.30×105Cfu/g) and option C control (4.3×104 −1.69×105 Cfu/g) respectively. Changes in physicochemical parameters during the study showed reductions in nitrate, phosphate and TPH in all the options expect pH which showed slight increase in option C (6.20-6.24). Characterization and identification for bacteria revealed the following HUB genera Pseudomonas, Citrobacter, Bacillus, Corynebacterium, Micrococcus, Klebsiella, Staphylocuccus and Nitrobacter). The percentage losses in TPH from gas chromatography (GC) results showed the following; option A (44.24%) option B (61.08%) and option C - control (27.28%) respectively. The results from this study showed that option B, the application of poultry droppings as biostimulant was more efficient than the application of NFB in enhanced bioremediation of crude oil polluted soil, hence the use of poultry droppings which is available as organic waste, eco-friendly and cost-effective is recommended asbiostimulant for enhanced bioremediation in environmental cleanup of crude oil impacted-sites of the Niger Delta region of Nigeria. Key Words: Bioremediation, Crude oil polluted-soil, Biostimulation, Bioaugumentation, Poultry droppings, Nitrogen fixing bacteria.

This research work on material selection for subsea pipeline construction was carried out to analyze and recommend suitable material option that satisfies DNV-OS-F101 standard for subsea pipeline constructions which will not succumb to extreme conditions and performs well in unpredictable conditions in the Niger Delta Region of Nigeria. Crude oil is mainly transported through pipelines, structural failure of the pipelines will severely affect oil production processes and will cause huge economic loss. Data on oil pipeline failures in the Niger Delta region of Nigeria were gathered and the major causes were; corrosion, operational error, third party activities and mechanical failures which were associated with the construction materials and structures of the pipelines. Hence, material selection for subsea pipelines is of vital importance. This paper makes use of Technique for Order Preference by Similarity to the Ideal Solution (TOPSIS) Theory to make fuzzy evaluation of different material options for pipeline construction. Statistical data and experts’ knowledge were integrated in addressing data limitation. This paper utilizes related weights and normalized scores based on experts’ judgements and with the aid of value engineering (VE) method, material criteria based on DNV-OS-F101 standard and TOPSIS Theory to achieve the best material option. The analysis has demonstrated that the estimation of TOPSIS is reliable. The outcome obtained can be used to assist the decision maker in the selection of the best material option suitable for the construction of subsea pipeline in Niger Delta region.

Aim: The aim of this study is radiometric survey of oil and gas wastes and its health risks in Niger Delta region of Nigeria.  Study Design: This study was purely an experimental work which involves collection of samples and laboratory analysis. Place and Duration of the Study: This study was carried out at oil and gas company waste stream facilities and waste pipe market within Niger Delta region between June 2018 and May, 2019. Methodology: Sixteen samples (4 drill cuttings, 4 pipe scales, 2 sludges and 6 produced water) were randomly collected from four waste streams in six locations within the oil and gas production facilities and used pipe market. These samples were taken to the laboratory, prepared following the ISO procedure and packaged in a porcelain bottle, sealed and kept for twenty eight days in order to ensure secular equilibrium between 238U, 232Th and their progenies and counted with high purity Germanium detector (HPGe). The activity concentration of all the radionuclides were used to determine the radiological health risks using mathematical models. Results: The lowest and highest specific activity concentrations  of 226Ra, 238U , 232Th  and 40K, in solid wastes are 5.28±1.08 and 25727.75 Bqkg-1, 3.61±0.76 and 23021.73±1041.58 Bqkg-1, 2.40±0.56 and 21468.25±1125.57 Bqkg-1 and 35.31±2.38 and 1527.73 ±86.60 Bqkg-1 respectively. In the liquid waste, the lowest and highest activity concentration of 238U, 232Th and 40K are 0.34±0.15 and 1.11±0.28 Bql-1, 0.63±0.17 and 1.06±0.18 Bql-1 and 9.60±0.66 and 14.20 ±1.04 Bql-1 respectively. 226Ra was below detectable limit in the liquid waste except in one sample (CZI). Downhole pipe scales recorded the highest activity concentration of all the radionuclides. Surface pipe scale also recorded very high activity concentration of all the radionuclides. The radiological health risk parameters assessed from the activity concentration of these radionuclide were all above the safe reference levels in downhole pipe scales and surface pipe scales while they are within the safe values in other samples. The estimated Exposure rate for both solid and liquid wastes were higher than the recommended reference level of 600 µRh-1 and the associated dose rate was also higher than reference level. Conclusion: The result of this work revealed that downhole and surface pipes from oilfield commonly used in the construction of buildings and domestic overhead tank-stands are associated with high levels of ionizing radiation which may be detrimental to human health and the environment.

Exploration Activity

The discovery of crude oil in Oloibiri-a town in the present Bayelsa state, Niger-Delta region of Nigeria) in 1956 and the subsequent exploration activities have over the years impacted tremendously not only on the ecosystem and livelihood pattern of the Niger Delta but on the pattern of conflicts that has trended.. While resources accruable to Nigeria from sale of crude oil are shared by all, the impacts of oil spill an offshoot of crude oil exploration activities are borne solely by the Niger Delta region. Oil spill appears to have found a permanent abode in Bayelsa state; from Southern Ijaw to Sagbama local governments, Olodiama to Azuzuama communities. Local communities are faced with the problem of continuous oil spill. This in turn has brought about conflicts between oil bearing communities and oil companies. These conflicts in some instances led to shut down of operations of oil companies, vandalism, and reduction of Nigeria’s crude export. In view of the illustrated background, this study examined the strategies for management of oil spill related conflicts in Bayelsa state regarding that oil spill is a key impact of crude oil exploration activity. Findings revealed that the strategies deployed in the management of oil spill in the state can be categorised into three: community strategies, regulators and non-governmental organisations strategies.

Abstract Background: Over the years, the issue of environmental degradation of ecological resources from crude oil pollution and its human health impacts is receiving more global attention. The utilization of environmental models capable of predicting the fate, transport and toxicity of chemicals in spilled crude oil can provide essential knowledge required to deal with the complexity associated with the fate of volatile petroleum chemicals in the environment. Objective: This paper explores environmental fate of toxic volatile organics from oil spill in the Niger Delta Region of Nigeria.Methods: A critical analysis of available literatures/data from PubMed, Scopus, ResearchGate, Google Scholar, Jstor, including expert working group reports and environmental modeling using a screening tool (USEPA EPI Suite™) was carried out to determine the environmental partitioning of Benzene, Toluene and Naphthalene (BTN) respectively. The organic-carbon partitioning coefficient (Koc) was computed as a function of soil-water distribution coefficient (Kd) and percentage organic matter (%OM). This was utilized to determine the distribution of BTN in the environment and the possible risk posed on delicate ecological resources from crude oil pollution due to exploration and production activities within the Niger Delta Region (NDR), Nigeria. Results: Results from literature implicated sabotage and operational failures from pipelines as primary causes of crude oil spillages. Generation of a fugacity model using EPI Suite™ revealed that the behavior of BTN is greatly influenced by Koc values. The default Molecular Connectivity Index (MCI) showed that benzene and toluene will partition more into the water compartment while naphthalene will partition into the soil compartment. However, user-entered values showed all three chemicals partitioning more into the soil compartment. Aquatic toxicology estimation using Ecological Structural Activity Relationship (ECOSAR) revealed all chemicals not to be toxic even at over-estimated Koc values. Conclusion: This research established the usefulness of screening level environmental modelling tools in assessing environmental risk and hence helpful in developing site-specific models for monitoring chemicals in the environment which can assist governments, policy makers and industries in the design of appropriate regional disaster management plans.
