The petroleum industry destines in the whole world important resources to consultancies, training and software in different technical specific areas. An important area is that of thermodynamic properties or PVT of fluids. There exist companies entirely dedicated to this subject matter, as also business units inside major companies. Nevertheless, they all are from European or North American countries and none is known in South America to an equivalent level.

Phasety combines the scientific knowledge of the first international level in thermodynamic (Phd in Chemical Engineering Martin Cismondi) and more than one decade of work in development of software with languages and modern methodologies (Computer Engineer Martín Gaitan), to develop PVT Sur, the first simulator PVT of South America.
