Properties of Oils and Natural Gases (Volume 5)

File Size: 23.60 Mb

Traditionally, chemical and petroleum engineers engaged in production of oil and natural gas from reservoirs have not devoted much interest to details regarding the properties and compositions of the hydrocarbon fluids produced. Design of production schemes and equipment was mainly based
, on experience. This was, however, insufficient considering the enormous investments required for oil and gas exploration and production. Today production systems and equipment undergo detailed engineering analyses and careful design 1:0 optimize the amount of hydrocarbons produced and minimize the operating costs and investment.

Analysis and design of oil and gas production facilities and schemes require thorough knowledge of the thermodynamic and physical properties of hydrocarbon fluids. To know how much gas and how much oi~arator produces under given conditions, it is necessary to know the vapor-liquid equilibrium relationships and the_d~~sities of the mixture. Understanding. the flow processes in the reservoir requires knowledge of viscosity and SUTface tension. Heat exchanger design requires knowledge of the thermal conductivity of the flowing fluids. Other examples abound.

It would, naturally, be best if knowledge of the above mentioned properties was available from experimental observations. Those are, however, impossible to measure for all hydrocarbon fluids in all relevant conditions. The chief objective of this book is, therefore, to describe in detail how to use
mathematical models to accurately predict transport properties (viscosity and thermal conductivity), surface tensions, and thermodynamic properties (density, enthalpy and phase equilibria) of naturally occurring oil and gas mixtures. The book is intended for the design (chemical or petroleum) engi-
, neer in the oil and gas related industry.
