This source of heat has made it suitable for use as cooking gas. Various developed countries have been able to transport gas to homes for heating of homes and as cooking gas using grids while considering environmental conditions specific to that country. This study unveils a distribution mechanism for effectively transporting cooking gas safely to homes in Rivers State. This gas distribution plan is a one supplier strategy which could be government or private owned. Choba community was used as a choice case study because of its strategic position. Also, the gas properties such as RVP, Pressure and Temperature were analyzed together with the pipe properties. The project impacts on the major environmental components of the study area were assessed and considered. The distribution routes considered locations of present gas processin...

However, the 17 SDGs are thought to not be achievable by 2030 for several reasons that this study identifies. However, to get a critical and direct response to the realization of these goals, a profession that cuts across all disciplines and has direct involvement in project planning is needed, and project management was chosen for investigation. This article seeks to understand the function of project managers in the actualization of the UN SDGs because it was noticed that, despite how varied project management is in business, government, and NGOs, it hasn't been assigned a clear role. This became necessary because the majority of the SDGs' objectives and the criteria used to assess their success or failure are project-based and largely driven by non-state actors or NGOs. It is crucial to ...
Control and management of corrosion have always been the concern of oil and gas asset management ... more Control and management of corrosion have always been the concern of oil and gas asset management teams due to the challenging outcomes of failed facilities in service due to corrosion. Corrosion has an impact on human safety, environmental safety, and productivity; thus, it is important to know how corrosive an environment is in order to make the best investment decisions for facilities that are prone to corrosion. There are various ways of identifying environmental corrosivity, but there is no distinct map or relation with combined soil pH and resistivity impact unique to an environment that suggests the corrosion severity of such an environment, which could be due to the complexities of variables involved in defining the extent of corrosivity. This research aims to create a corrosion map using the MATLAB computing environment for Rivers State, a mega oil-producing state in the Niger Delta, based on soil resistivity and pH across different parts of the state with ongoing oil and ga...
The challenge of data availability for accurately assessing a location's level of corrosivity... more The challenge of data availability for accurately assessing a location's level of corrosivity has lingered for so long and as such, researchers are constantly seeking factors with great influence that can assist in describing how corrosive a location will be toward buried oil and gas infrastructure. Alternative measures are required for making rapid and realistic investment decisions because accumulating these factors to make perfect sense is sometimes time-consuming and expensive. Using MATLAB mathematical computational analysis, this study capitalizes on this gap to build a 3D corrosivity signature and model for Delta state, Nigeria to aid in rapid and realistic investment decision-making. The soil pH and resistivity were identified as key variables that determine the extent of corrosion in this investigation. Vertical Electrical Soundings were utilized to collect soil resistivity data, which was then combined with the soil pH to create a 3D corrosivity signature and model wit...

The oil and gas business has lost millions of dollars owing to corroded pipes, making it vital to evaluate the severity of environmental corrosion before making investment decisions. The Niger Delta, which is a hub of oil and gas activity in Nigeria, was the focus of this research. This research aims to reduce the impact of environmental corrosion on buried oil and gas assets by creating a corrosion map and model tailored to the environment in order to identify the level of corrosion severity at various points. 93-points soil resistivity data were collected using Vertical Electric Sounding (VES) and the Werner method, while average pH data from Rivers, Bayelsa, and Delta States were gathered from research within the Niger Delta. The extent of corrosivity in the envi...

With the importance the petroleum sector has attained in Nigeria, it is expected that the country's pedagogy will reflect the value it contributes to the national table. However, reviews, surveys, and works of literature have shown otherwise. As a result, this study emphasizes the importance of petroleum engineering pedagogy in-country as an oil-producing country, the university curriculum of petroleum engineering in Nigeria was also examined (with a particular focus on the impact of poor curriculum on national development), and the dynamics between the university, industry and government were critically discussed and recommended practices for improving petroleum engineering pedagogy were made. This study targets national development and control over its own resources through a knowledge economy and s...

This study attempts to understand if these calls are due to “cartelization by political bodies” as described by Libecap, in 1972, promotion of self-benefits, or genuine calls based on disastrous impacts of global warming and general climate changes. Alternative energy sources and their present sustainability will be examined, policies affecting fossil fuels over time will be identified, the effects of these global and national policies, the politics behind calls and perspectives from various continents will be discussed, the lowest and highest GHG emitters will be identified, and recommendations will be made on the best course of action based on reviews and findings from around the world. Furthermore, this study understands that the world is a global village and considered the effect of climate change as a global challenge, however, its arguments and suggestion were made by critical ...

The formation of Hydrates is an important issue likely to cause clogs in pipelines during production and transportation of oil and gas. Therefore, production and transportation of such fluids are simulated using software’s like Unism to know the possibility of hydrate occurrence so they can be avoided. This work is based on the simulation of processed well effluents from Rose Field to analyze the hydrate formation temperature and water dew point at different points of the process facility. At the crude oil line the hydrate formation temperature was 69.9565°C, while the water dew point was not defined because it’s a liquid phase. At the gas line the hydrate formation temperature was 4. 7975°C at 1803psia and water dew point was -42.7°C. These values are parameters necessary for hydrate formation prediction, hence, they were analyzed and recommendations made to manage effecti...

A software has been developed to effect a smart control algorithm. This results in a bean up or bean down operation depending on the current flowing conditions and constraints. Excel programming environment was used to write a code that constantly takes in measured data points, models the behavior of the individual data sets with bean size and controls the choke if the parameters of interest go above a predetermined cut-off. The software was also equipped with an inverse matrix solving algorithm that enables it to determine the choke performance constants for any set of initialization data. A set of data from field X were supplied and the choke performance constants; A, B, C, D and E, were found to be 10, 0.546, 0.0, 1.89 and 1.0 respectively. In addition to that, data from subsequent production operations were entered and the software was able...

To handle this challenge, the fracture pressure of the formation must be known as it is significant to determining the mud window design. This study developed a correlation that could predict the formation fracture pressure in the Niger Delta deep offshore field. Two different fields were considered for this model named Field 1 and 2. From these fields, fracture pressure data were gotten from 21 wells during leak off test (LOT) at different casing shoe depths. While carrying-out the analysis of data, assumptions were made that the formations throughout the Niger Delta basin obeys the principle of horizontality. Also, that the fracture pressure at same depth is uniform with the pressure at other location in the Delta. Scatter plot was used as the tool for the data analysis. A line of best fit was drawn to ...

Different oil producing countries have their own laws governing petroleum activities and these laws vary from country to country based on the B-PEST factors which are Biological, Political, Environmental, Social and Technology. However, reserve size and oil type can also influence petroleum laws. Countries like Nigeria relies strongly on petroleum bills such as the PIB in which this research will be analyzing the Production Sharing Contract (PSC) which is a significant subset of the PIB. Comparison between the existing PSC of Malaysia and that of Nigeria was captured in this research and the analysis of the PSC was done based on the Government Take, National Oil Company (NOC) and the Contractor’s benefits. 26.67% and 56.58% recovery cost, 28.67% and 26.28% Government revenue, 23.14% and 7.64% ...

It is fixed by producing countries or countries in a consortium through organizations such as Organization of the Petroleum Exporting Countries (OPEC) or a particular mix of crude oil such as the West Texas Intermediate (WTI) or Brent. The spot price and future prices of crude oil is basically determined by demand and supply, however, some external factors can have great influence on oil price. This research work will be emphasizing on the direct and indirect effects of the COVID-19 pandemic as an external factor other than demand and supply on the benchmarks of oil pricing between 2000 and 2020. Having analyzed the various oil price fluctuation which have been caused by several factors over the years, this research went further to identify those significant factors, weigh them and input them into a model that will generate simulated oil prices of past, present and future benchmarks with relation to demand, ...

The corrosion of pipelines can occur in different ways, as materials tend to go back to original state. This work focused on the erosion corrosion of pipelines due to sand production. Several analysis following best practices introduced in this work where carried out on field inspection data on pipelines and flowlines in which a trend was identified. This trend generated models such as erosion trend angle (ETA) and erosion trend factor (ETF) which will be used for reviews, judgment and sensitivity analysis during corrosion management. The criterion for criticality of ETA was 30 degrees for the purpose of this work and recommended that users could vary to fit work objectives. Five test points where used to establish ETA and ETF values for major decision of criticality for erosion corrosion as shown in Table 2. To enhance the use of these models and know...

The significant impact of crude oil as a source of energy has made exportation and importation of this mineral a lucrative business around the world, having turned to be the major source of revenue for most producing countries. Crude oil has contributed to about 80% of Nigerian Government revenue and foreign exchange since 1958, making it a key player in the economic plan of the country. Its importance in Nigeria has made the Legislature introduce lots of policies and laws governing the Oil and Gas business in the country. However, Nigerians with different views over the years have clamored for an improvement of these policies to enable the benefits of Her resources fairly get to the grassroots, producing communities and states while improving foreign investment policies in the country. These demands led to the introduction of...

This study examines the Alwyn North field and presents a comparative analysis for producing crude oil using water drive, gas drive and natural drive or depletion drive. The Eclipse Simulator was used to simulate different scenarios of well placement and performance tools such as FOPR, FPR, FWCT, FGOR and FOE was used during simulation to compare the outcomes of the well placement. Economic analysis which is key in decision making was carried out using economic tools such as Gross Profit Margin (GPM), Net Present Value (NPV), Payback Period, Internal Rate Return (IRR) and Profitability Index (PI). The payback period for water injection was 2.1years and 1.99years for gas injection. IRR was 53% and 48% for water and gas injection development schemes respectively and Profitability Index for water injection was 1.73 and 1.36 for...
