In the petroleum industry, the accurate determination of hydrocarbons initially in place is critical for effective reservoir management and the formulation of efficient production strategies. This research focuses on the evaluation of a saturated oil reservoir in an onshore Niger Delta field through the application of Material Balance Analysis (MBA). The objectives of the study include estimating the initial oil in place, evaluating the presence and strength of an underlying aquifer, identifying the dominant reservoir drive mechanism, and recommending an optimal production scheme capable of maximizing economic recovery. For this research, the majority of the reservoir and production data were obtained from Nigerian National Petroleum Company (NNPC), which also provided access to the MBAL simulation software. MBAL is a simplified yet powerful analytical tool that applies the concept of material balance to characterize reservoir behavior. The program models the reservoir using a zero-dimensional (tank) approach, which does not explicitly account for geometry, drainage area, or well orientation, but provides valuable insights into fluid distribution and drive mechanisms by analyzing production and pressure performance. The results from the MBAL analysis indicate that the reservoir contains an estimated 250.258 MMSTB of oil initially in place, and the predicted volume of water in place to be 99788.4 MMft3 . Furthermore, the aquifer’s influence on reservoir pressure performance demonstrates that water drive is the predominant drive mechanism sustaining production. These findings provide a reliable basis for planning production strategies that optimize reservoir performance while enhancing ultimate recovery. In carrying out this research, valuable hands-on experience was gained in data handling, diagnostic plotting, and MBAL simulation. The work strengthened descriptive, technical and analytical competence in reservoir evaluation and provided deeper insight into the importance of accurate data interpretation for sustainable hydrocarbon recovery in the Niger Delta basin.

Tracking the Forensic Analysis of BOP & Considering Key Factors Affecting Performance during Blowouts; This research delves into the crucial field of blowout preventer (BOP)forensic analysis, examining the complex interplay of factors influencing their performance during well control emergencies. The study meticulously tracks the evolution of BOP technology, regulatory frameworks, and prevalent failure mechanisms. It unveils the intricacies of forensic analysis, encompassing data collection, analysis, and reconstruction of events leading to BOP failures.

By scrutinizing various case studies, the research identifies key factors impacting BOP performance, including operational procedures, equipment design and maintenance, environmental conditions, and human error. It analyzes the implications of inadequate drilling practices, improper well control protocols, design flaws, manufacturing defects, and the influence of extreme pressure, temperature, and sea state on BOP function. Additionally, the study emphasizes the significant role of human factors, including operator training, communication, and decision-making, in contributing to or mitigating BOP failures.

Drawing upon this comprehensive analysis, the research culminates in a series of practical recommendations for improving BOP performance and safety in the oil and gas industry. These recommendations encompass enhancing operational procedures, strengthening equipment design and maintenance practices, mitigating the impact of environmental conditions, and minimizing human error.
