PETROLEUM RESERVOIR DRIVE MECHANISMS

Oil Reservoirs description: Oil can be recovered from the pore spaces of a reservoir rock, only to the extent that the volume originally occupied by the oil is invaded or occupied in some way. There are several ways in which oil can be displaced and produced from a reservoir, and these may be termed mechanisms […]

TYPES OF NATURAL GAS RESERVOIRS

GAS HYDRATES DEFINITION, PRODUCTION AND FORMATION CONDITIONS. Gas hydrates are crystralline compounds, formed by the chemical combination of natural gas and water under pressure at temperatures considerably above the freezing point of water. In the presence of free water, hydrate formation is often confused with condensation, and the distinction between the two must be clearly understood. […]

NODAL ANALYSIS – PETROLEUM ENGINEERING

INTRODUCTION TO NODAL ANALYSIS After a well is drilled and  completed, itrequires a great effort to transport or flow fluid through the reservoir until the piping system and ultimately flow into a separator for gas-liquid separation which are placed on the surface. the movement of these fluids requires energy to overcome friction losses and to lift the products. The pressure drop […]
