“…Some researchers have tried to employ these natural fibers in some applied fields [ 18 , 19 ]. In the oil and gas industry, the possibility of using pine cone powder as an additive to water-based drilling fluids has been investigated [ 20 ]. Tonnes of pine cones are produced every year around the world and are still environmentally neglected [ 16 ].…”

Municipal solid waste (MSW) management is a critical issue in the Kingdom of Saudi Arabia (KSA). Management of solid waste in crowded conditions, especially in main cities such as the Al-Taif Province. This paper deals with that case study and focuses on how to solve material handling problems by applying conventional methods and computer ability. One of the costliest operations in the civil sector is transportation for material handling. City mayors considered transportation and materials handling as a subclass of the linear programming technique, thus linear programming problems take into consideration that the main objective is to handle materials from the city centre site to the identified dumping area. There are many methods and tools used to solve the transportation problem (TP) to find out the maximum or minimum in order to reduce cost or maximize profit. The methods related to manual solutions and others used many different computer applications. Manual solutions include the northwest corner method, the minimum cost method, the row minimum cost method, the column minimum cost method, and Vogel's approximation method, and computer applications such as LINGO, Lingo, and solver function using Microsoft Excel. This case study focuses on applying the Microsoft Excel function to find the minimum cost of the transportation system in waste materials to reduce the transportation cost from the city centre to the final destination (dumping area) to be used. The results achieved with the model aided in obtaining optimal solutions and finally, the optimal solutions were checked.

Gas influx management is critical in oil and gas drilling operations, which aims to prevent the uncontrolled outflow of formation gas and the potential consequences caused by blowouts. When gas influxes enter a wellbore or marine riser and migrate within the non-Newtonian drilling fluids, the gas suspension behaviors can noticeably impact the influx migration behaviors. This effect is particularly important to consider during the gas migration process in a non-circulating well, where the monitoring and accurate prediction of pressure changes in the well are essential. This study investigates the distribution of gas influx and Interfacial Area Concentration (IAC) during gas migration through full-scale experiments and numerical simulations. Downhole gas influxes were simulated by injecting gas into the bottom of a 5,160 ft-deep experimental wellbore using a Synthetic oil-based Mud (SBM) system. Helium, which shows a minimum solubility in the SBM, was selected to simulate the downhole gas influx. The Distributed Fiber-Optic Sensing (DFOS) data was obtained in high-resolution to monitor the gas migration behavior, and the gas slip velocities, slug length, and suspension concentrations were analyzed based on the measurements. A numerical simulator was developed based on the Two-Fluid Model (TFM) and the Interfacial Area Transport Equation (IATE) to simulate the gas influx behaviors. The experimental data were compared with the model predictions. The results of this study indicate that the numerical modeling framework utilizing IATE effectively captured the behavior of bubble breakdown, coalescence, and suspension by enabling the estimation of interfacial area distribution. The model predictions demonstrate a strong agreement with experimental data, including gauge measurements, Distributed Temperature Sensing (DTS), and Distributed Acoustic Sensing (DAS). The accuracy of model estimation was significantly improved compared to models such as the Drift-flux Model without the integration of IATE, particularly in the interpretation of gas suspension. Through sensitivity analysis, this study reveals the substantial impact of gas bubble dispersion and suspension on the level of surface pressure buildup, which can be attributed to significant changes in the overall system compressibility. In addition, the presented case study was translated into field predictions (the migration of methane influx in water-based mud (WBM)) based on the proposed and validated models. The obtained results provided valuable references for field applications. The experimental data with Helium and SBM from this study is critical for better decoupling and facilitating the understanding of the underlying physics involved in gas migration. In addition, this is a novel practice to implement the IATE in well-scale multiphase flow simulations, which has proved to be an effective tool for predicting the dynamics of gas influx distributions. The results of this study provide critical insights into the design and optimization of gas influx management during Managed Pressure Drilling (MPD).
