Microorganisms square measure thought of to have an effect on the properties of drilling fluids. This work self-addressed the subsequent sections: the character of Micro-organisms, microbic Mechanisms that have an effect on Drilling Fluids, Implications of microbic Contamination and Identification. This work focuses on the likelihood of utilization of microbes as basic material for lubricant. This analysis assess by means that of straightforward however relevant laboratory, the properties of the microbes cultivated from banana skin within the micro-biological laboratory and compared with commonplace drilling fluid. The results were analyzed exploitation applied mathematics and graphical ways. Water based drilling muds were developed with the microbes and characterised to work out the properties like density, rheology and pH within the laboratory and compared with those of the standard laboratory mud. Results showed enhancements in sure properties, but it verified unsuitable in different properties in comparison to straightforward drilling fluid. I.

In optimizing glycol dehydration system for the natural gas processing, several critical parameters that can be varied to achieve specific dew point depression exist. From HYSYS simulation, a gas plant was placed under investigation with the aim of studying the effects of variation in glycol flow rates, number of stages (4, 8 and 12 trays)

The limitation of Steam Injection to depths has been a subject of concern in the application of SteamInjection for heavy and extra heavy oil recovery. This is usually as a result of the complex mechanism of heat loses occurring in the wellbore and consequently the heat loss distribution in the reservoir. A conventional approach to the optimization of steam injection has been based on isolated analysis of the well system aimed at maintaining adequate steam quality at the sandface at optimal injection rate, pressure, temperature and overall heat transfer coefficient. This often results to total neglect of the effect of the interaction between the well system and the reservoir system in the Model results. This research presents an integrated approach in the modelling of steam injection project that incorporates both the well system and the reservoir system. In this study, a three case-study wells were analyzed which are located at INJ1 (1, 1), PROD1 (5, 5) and PROD2 (9, 1) respectively. The results of the findings reveals that the conventional practice of maintaining sufficient SQ at the sandface is not the last optimization strategy in real field scenario. This is because the efficiency of the heavy oil displacement by the steam is a co-function of the effective SQ at the sandface, the FHLR/FHLT and the relative distance of the injector(s) from the producer(s) which are characterized by the thermal properties of the reservoirs. As part of the objectives of this study, a novel numerical approach using PROSPER wellbore simulator is presented for analysing the impact of reservoir back pressure on the estimated SQ. The results as presented in the work shows that wrong estimations of downhole SQ can result from the total neglect of Reservoir Pressure especially in relatively deeper wells.
