MODELLING OF OIL AND GAS MANAGEMENT AND OPERATIONS IN NIGER DELTA REGION; A CASE STUDY OF NIGERIAN NATIONAL PETROLEUM CORPORATION (NNPC

ABSTRACT
The problem of the Niger Delta region remains unsolved, after so many years of oil and gas
exploration and production. It seems that these problems cannot be solved, since demands cannot be
met based on the approaches adopted by Government in addressing the issues or demands/needs of the
region. Federal Government have made several efforts to address these problems in the region, those
efforts have proven unsuccessful, more especially on a long-run. Indicating that the issues of the region
have not being confronted as it directly affects the people. Hence a wrong methodology or approach
has being used in addressing the issues of the region which cannot provide permanent solution. This
research work is on modelling of oil and gas management and operations in Niger Delta (a case study
of NNPC). It analyses the relationship between NNPC (Government) and Host Communities (Oil
producing areas of Niger Delta region), using developed models (M1, M2 & M3) to quantitatively
arrived at its parameters. It looks at the demands of the region and how efficiently NNPC have
manage their resources (oil & gas) to meet those needs/demands, which is a basic concept of
management (using available scarce resources to meet needs). And the reasons for continue conflicts
and agitations (unrest) in the region, and as well as the type of relationship existing with Government
(G) and the Niger Delta (N); the stages and degree of conflict escalation in the region and other
relevant case studies (Ken Saro Wiwa & Shell on Ogoniland). The main component of the developed
model 2 (M2) is to address the concept of management (using the available scarce resources to meet the
needs/demands of the people). Therefore for effective and efficient utilization of resources in the region,
needs/demands must be met. Hence Resources (R) available must be directly proportional to demands
(d) which is equivalent to Resources Control (RC). But in the case where Resources available is
inversely proportional to demands of the people agitations will continue, until a point where resources
directly proportional equals to resources inversely proportional known as Equity Share (50%
derivation). Mathematically represented as R = Ed (Equivalent to resources control), R = E/d
(agitations continues) and Ed = E/d (Equity share). Where E = constant (E ≤ 100%). Therefore the
analysis of the model (M2), the results shows that the actual demand (dA) of Niger Delta region is
98.3% (oil derivation) of its total resources produced with a leftover of 1.7% (tax allowance) and tax rate
of 17.93%. It is an indication of the demand for resources control (RC) and fiscal federalism at a tax rate
of 17.3% to be paid to Federal Government. But Niger Delta States gets 13% (oil derivation) while
Federal Government (G) gets 87% of the total resources (oil and gas) produced in the region. Therefore
it indicates that R = E/d; hence agitations will continue in the region. And the rate of deviation
(between RG and RN) is 74%, and the rate at which resources has being diverted in the region is 64.4%.
The analysis of the human relation, model 1 (M1), indicate that there is a poor mutual relationship
between G and N. With 13% zone of shared power (PS) and 87% of zone of unshared power (RO), and
the strength of the shared power is at a ratio of 11% : 2% (G:N). Where the point of intercept is 39%
and the resistive intercept which oppose the mutual relationship is at 61%, indicating too many
personal interests in the kind of relationship that should exist between G and N. From the analysis of
model 3 (M3) and the conflict escalation chart the degree of conflict escalation (CE) is +266.40
NNPC/OC HC/NNPC/En/OC. This means that the conflict lies on the third quadrant, and
therefore could be trace to NNPC/OC as the major cause and mostly affected if there is violence, and
resolution lies primarily on HC/NNPC/En/OC.

ABSTRACT

The research paper review risk and hazard identification and assessment in modern construction with the aim of examining ways risk and hazard can be managed in modern construction. The team carrying out risk and hazard evaluation must be able to recognize potential sources of hazards that workers may be expose to, document it and rank the hazards in order of priority, those hazards with the highest potential to cause an injury, illness or death are to be address first and where a hazard cannot be assessed, administrative changes can often be used to reduce the amount of exposure a worker has to the danger. Therefore, risk and hazard identification and assessment on construction sites cannot be over emphasized, it is a good step to achieving environmental friendly construction site. Supervisors should make sure that control measures are put in place to abate any identified risk and hazards, disciplinary measures on abuse of risk control measures should be established for workers, supervisors and contractors by the relevant professional body.

Keywords: Hazard control; Worksite inspection; Hazard evaluation; Risk assessment matrix; Potential exposure route.

ABSTRACT

The study examined the agents responsible for self-healing concrete in modern construction. Survey research design was employed for the study; the study population was made up of 600 construction workers in the south-east geopolitical zone of Nigeria. 240 workers were used as sample using taro yammney formula to determine the sample size and simple random sampling technique to determine which of the 600 workers should be selected as sample. Mean and analysis of variance (ANOVA) were used for data analysis. From the findings, bacterial, mineral additives and adhesive agents are responsible for self-healing in concrete and no significant difference exist in the rating of the agents on different sizes of buildings. Therefore, self-healing agents are essential in the achievement of sustainable concrete in modern construction. Building professionals should be trained on self-healing concrete. Government should ensure the availability of the agents and subsidize its price. The public should be sensitized on self-healing concrete through seminars and advertisement by the Council Registered Builders of Nigeria (CORBON).

Keywords: self-healing agents; Self-healing process; Impact of self-healing concrete.

ABSTRACT

This work was conducted to assess the level of ionizing radiation from select dumpsites within Eket Local Government Area.  Five dumpsites were selected, with site one at Hausa’s quarters, Site two at Market Road, site three at Ibeno road, site four at Qua steel and site five at Ikot Ebok road. This was achieved using a portable inspector alert nuclear radiation monitor with serial number1212 made in U.S.A to measure the radiation exposure rate in micro Seviert per hour. The measurement was conducted at reference dumpsites up to about ten (10) spots per dumpsites. The results obtained shows that average absorbed dose rate of the measurement in dumpsite one was 0.17mSv/hr, dumpsite two was 0.15mSv/hr, dumpsite three was 0.14mSv/hr, dumpsite four was 0.16mSv/hr and dumpsite five was 0.18mSv/hr. Dumpsite five produced the highest radiation dose rate which could be as a result of high level of waste dump, decay duration nature of waste generated the average dose rate of about 0.18mSv/hr. This study suggested that these dumpsites generates radiation dose into the environment which are hazardous to humans, animals as well as plants around the dumpsites and therefore, waste should be controlled and managed properly in order to reduce the level of radiation.

ABSTRACT

The purpose of this study was to find out the relationship between workload and participation in leisure activities among civil servants of Katsina State Nigeria. To achieve this end, Ex-post Facto Research Design was adopted. The population for the study comprised of civil servants from all ministries, departments, agencies, boards and other parastatals in Katsina State, Nigeria- totaling to 18,487, from which proportionately, 400 respondents were issued the questionnaire and 377 of the questionnaire were retrieved upon which the data analysis was conducted. In this study, welfare of the civil servants, which is a strong indicator of job satisfaction, was correlated with their participation in leisure activities in form of social, educative and sporting perspectives. The demographic characteristics of the respondents were analyzed using frequency and percentage table, whereas, the Pearson Product Moment Correlation Coefficient (PPMC) was used to test the null hypothesis with the decision mean placed at  3.5 and the level of significance was set at 0.05.The result revealed that the two variables –workload and participation in leisure activities were significantly related with an observed correlation coefficient of 0.913. The major findings from the study showed that workers’ workload is significantly correlated with participation in social, educative and sport related leisure activities among Katsina State civil servants. To this therefore, the researcher concluded that workloads a strong indicator of job satisfaction correlates positively with participation in leisure activities among Katsina State civil servants and finally recommended that, Katsina State Civil Service Commission should raise more awareness on the roles of leisure activities in the productivity and all round development of civil servants by providing opportunities during break time (despite their workload) to enable them participate in one or more recreational activities.

ABSTRACT

The study assessed construction technology trade students’ attitudes towards post-secondary technical vocational education and training in Benue State, Nigeria. Two research purposes, questions and one null hypothesis were raised to guide the study. The descriptive survey design was used for the study. The population of the study was 130 which comprised 55 carpentry and joinery students and 75 Block- laying/Bricklaying and concreting students in science and technical colleges within Benue State. A 10-item attitude scale titled: Construction Trade Students Attitudes towards Postsecondary Technical Vocational Education and Training (CTSAPSTVET) rated on a 3-point category was used as instrument for data collection. The descriptive statistics of mean and standard deviation was used to answer all the research questions whilst an inferential statistics of independent sample t-test was employed to test the null hypothesis at 0.05 level of significance. Findings from the data analysed revealed amongst others that: Carpentry and Joinery students who are said to constitute the predominant prospective entrants for post-secondary technical vocational education and training programmes are of a neutral disposition as regards whether they would pursue studies in this area. Attitudes of Block-laying / Bricklaying & Concreting students towards post-secondary technical vocational education and training are ambivalent. Based on the findings, recommendations were made that: Vocational guidance counselors, teachers and school principals should always organize orientation and workshops for carpentry and joinery students where these students will be educated on the importance of post-secondary technical vocational education and training programmes. Vocational guidance counselors and technical subject teachers should always provide a proper orientation for block laying / brick laying & concreting students on the need to advance in their already chosen trade.

ABSTRACT
Drawing studios are very crucial to the performance of students of architecture. An evaluation of existing drawing studios could foster their improvement and services and appropriate actions can be taken to restore or retain them to acceptable standards. Studios are currently faced with challenges as a result of learning space in tertiary institutions being detrimental, decayed and dilapidated infrastructural facilities due to lack of maintenance. Physical facilities in over 90 percent of the institutions of higher learning in Nigeria are in poor states. Spaces provided in tertiary institutions in Nigeria for most departments of architecture are grossly inadequate for lectures or practical works. Most drawing studios do not permit meaningful relations between lecturers and students. These conditions possess tremendous challenges to effective teaching and learning. This paper examines the relationship between the existing features in the drawing studios and users’ satisfaction at the Federal Polytechnic, Ilaro. A questionnaire and checklist was used as a data collection instrument for the study. Data was analysed using the descriptive and the inferential statistic tools. The study revealed that users were not satisfied with the performance of the studios. The study recommends that more drawing studios with state of the art facilities should be provided and maintenance culture should be imbibed in Federal Polytechnic, Ilaro.

ABSTRACT

Mathematics has continued to receive attention in Nigeria since independence; this is because mathematics is the stem for scientific and technological breakthrough. It is sure that despite the effort been put in to up lift the standard of mathematics in schools the result have not been satisfactory. Different reforms have been made in education in other to improve the understanding of mathematics because of its strategic position in nation building. Many authors have raised issues that affect the understanding of mathematics to include, issues of mathematics teachers education, professional development of mathematics teacher, overcrowding mathematics classroom, challenges of mathematics strategies for teaching and sustaining mathematics learning. These views will put mathematics teachers and learners in the right direction of understanding and teaching mathematics.
