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.

Anova Model

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 objective of this research work is to examine two prominent dom gas reservoirs H1000 and H4000 in onshore Niger Delta region of Nigeria for potential production activities using seismic wavelet and well-to-seismic tie process to facilitate interpretation and evaluate dom gas (hydrocarbon) bearing formation. Well log and sidewall samples analyses show that the velocity attributes, high P-wave, S-wave and Vp/Vs ratio characterize sediments with high concentration of dom gas. The wells validated the presence of dom gas with total gas in place on the field estimated at 4.017 trillion ft3, GIIP 5,228.683 bscf, CIIP 445.136 MMstb, and STOIIP 34.647 MMstb, URg 4,120.494 bscf and URc 219.208 MMstbl, 90 % of which resides in the two reservoirs. The hydrocarbon intervals are estimated at H1000 (8864 ft, TVDSS) and H4000 (9577 ft, TVDSS). The borehole information was combined with seismic data to confirm lateral continuity of the dom gas reservoirs.

This study sought to investigate factors militating against community participation in development projects executed under the Micro Projects Programme and how to reduce such factors to the barest minimum in the Niger Delta region of Nigeria. A cross-sectional survey design was adopted for the study. A questionnaire, an in-depth interview (IDI) guide and a focus group discussion (FGD) guide were used for data collection. Borehole water, generator-house, health centres, staff quarters and markets were the projects executed. Inadequate devolution of power to the grassroots, among others, was the major problem that hindered involvement of community members in the development process of the Micro Projects Programme in the study areas. To enhance active participation of beneficiaries in the development process of the programme, suggestions are proffered.
