Comparative Analysis of Oilfield Chemical Operations Using Deterministic and Stochastic Models

Efficient management of oilfield chemical operations is paramount for enhancing production, minimizing risks, and maximizing profitability in the oil and gas industry. This study presents a comprehensive comparative analysis of deterministic and stochastic modeling techniques to optimize oilfield chemical operations. Focusing on demulsifying and matrix acidizing operations in Nigeria, the research employed deterministic (Critical Path Method - CPM) and stochastic (Program Evaluation and Review Technique - PERT) models for analysis. Results demonstrate the deterministic model's ability to provide precise completion time estimates, while the stochastic model factors in uncertainties and variability, yielding slightly different but more flexible completion time predictions. Both models identify the Critical Path, yet the stochastic model offers probabilistic estimates, enhancing risk assessment and mitigation capabilities. Despite potentially longer completion times, the stochastic model emerges as the preferred option due to its adaptive approach and ability to incorporate uncertainties, ultimately improving project planning and risk management in oilfield operations. This study contributes to advancing optimization strategies in the industry, providing decision-makers with evidence-based insights to enhance operational efficiency and sustainability. By understanding the strengths and limitations of both modeling techniques, project managers can leverage the probabilistic insights offered by stochastic models to optimize project outcomes and effectively manage uncertainties in oilfield operations, contributing to improved operational efficiency, cost reduction, and enhanced productivity in the oil and gas industry.
