Constructing phase diagram and its subsequent quality lines for lean gas condensate reservoirs is always crucial and challenging topic in reservoir fluid studies. Due to small amounts of liquid drop-outs in lean gas condensates at reservoir conditions, full experimental tracking of phase diagram and its relevant quality lines is almost impossible for lean gas condensates.On the other hand, ...

Using a van der Waals gas as the working substance the so called Curzon and Ahlborn-Novikov engine is studied. It is shown that some previous results found in the literature of finite time thermodynamics can be written in a more general form, means of this gas and by taking a non linear heat transfer law. 1. Introduction In classical equilibrium thermodynamics the efficiency of a reversible the...

The layering of protocols in critical infrastructure networks – exemplified by Modbus TCP in the oil and gas sector and SS7oIP in the telecommunications sector – raises important security issues. The individual protocol stacks, e.g., Modbus and SS7, have certain vulnerabilities, and transporting these protocols using carrier protocols, e.g., TCP/IP, brings into play the vulnerabilities of the c...

The age of Jupiter, the largest planet in our Solar System, is still unknown. Gas-giant planet formation likely involved the growth of large solid cores, followed by the accumulation of gas onto these cores. Thus, the gas-giant cores must have formed before dissipation of the solar nebula, which likely occurred within less than 10 My after Solar System formation. Although such rapid accretion o...
