This paper examines the effect of high concentrations of the heptanes-plus fraction in natural
gases on the calculation of gas compressibility (Z) factors. Laboratory measured gas …

Oil and gas production in the broad sense of the word can be subdivided into three more or
less separate fields of science and technology, notably (1) production processes in the …

A steady-state mechanistic model is formulated to predict the mixture behavior for upward
two-phase flow in concentric annuli. It consists of a procedure for flow pattern prediction and …

Compressibility factor (z-factor) values of natural gases are necessary in most petroleum
engineering calculations. The most common sources of z-factor values are experimental …

In recent years, non-Darcy flow has seen a significant increase in interest in the petroleum
industry, especially in flow in fractures—both artificial and natural. In hydraulic fracture …

Gas compressibility factor (z-factor) is an important parameter widely used in petroleum and
chemical engineering. Accurate and fast calculation of this parameter is of crucial need and …

Compressibility factor of natural gases is necessary in many petroleum engineering
calculations. Some of these calculations are: evaluation of newly discovered formation …
