    Analysis of factors militating against successful building construction project delivery in South-East Nigeria
    (Federal University of Technology, Owerri, 2023-11) Ejiogu, Ejike F.
    The study examined the factors militating against successful building construction project delivery in the Southeast, Nigeria with the objective of identifying and analyzing the militating factors for decision purposes. Six (6) militating factors were identified. Based on this, five-point Likert’s scale, questionnaire was designed and distributed to 226 respondents for assessment. The multiple regression analysis result show that the average performance achieved in building onstruction delivery is 27.017 which is statistically low. The model developed show that all the factors with the exception of government policies and level of skilled workmanship exhibited negative influence on building project delivery in the Southeast States. The hypotheses test show that non-adherence to standard building codes is most critical to building project delivery. In view of these findings, the study recommends strict adherence to professional building codes, the creation of enabling environment through policies and programmes that will encourage the proper planning and implementation of building construction projects, Government development policies should be strengthened in order to control inflation and avoid constant increase in the cost of materials for building construction projects. Also, skilled workers should be engaged and, the cost and process of obtaining government approval should be made more affordable and simple so as to encourage improved success in the building project delivery and enhancement of socioeconomic wellbeing of the citizens.

    Comparative analysis of IPR models for oil & gas well optimization using production performance software (PERFORM) for steady state horizontal wells
    (Federal University of Technology, Owerri, 2021-04) Nwude, Afam Anthony
    In this work an investigation of the formulations and solution methods for the following optimization problem was done. Determination of the optimal production rates, lift gas rates, and well connections to maximize daily operational objectives subject to multiple flow rates and pressure constraints.The main materials used in this research are presented as software platforms. IHS PERFORM Ver 500 simulator was used to generate PI, determine Inflow and Vertical Lift Performance of the case study well at varying well pressure and flow rates (first on natural flow without artificial lift installed). Microsoft Excel package was used for Economic Analysis to determine the profitability of PERFORM when compared with other software tool such as Petex-Prosper, or with no software tool used. All of the optimization problems are solved using derivative-free optimization based on a constrained well Performance Analysis, PERFORM. General descriptions of the software simulations were provided in the work. Results of the sensitivity analysis on the hypothetical case using the IPR Models for horizontal gas wells provided the effect on pressure and liquid drop out.This method is very efficient. However, it may lead to bad solutions when the flow interactions among wells are significant.
