Περίληψη
In this thesis, the issue of the properties of the fluids that appear in the hydrocarbon reservoirs has developed. Hydrocarbon reservoirs are single reservoirs with a specific fluid composition, specific volume, but also specified pressure and temperature conditions. Within these porous rocks known as reservoirs, large concentrations of hydrocarbons appear. A basic condition for creating a concentration of hydrocarbons is the existence of geological structures that will play the role of a trap. During the productive life of a reservoir there are up to three distinct phases (oil-gas-water) with their proportions altered according to the pressure change. For the proper management of reservoirs, pressure-volume-temperature (PVT) analyzes must occur, as well as physical and chemical analyzes by specialized laboratories, must be performed on fluid samples taken from different locations. Appropriate measures must be taken to avoid poor samples which will give incorrect measurements. One of the main goals of both sampling and laboratory testing is to determine the exact nature of the fluid. The type of fluid will also affect how it will be sampled. Depending on the knowledge available, requirements for samples and laboratory studies will also be defined. If there is not enough information about the reservoir, an extensive research drilling program is being carried out to get a correct set of fluid information, where future exploration work will be based. Having made the right measurements, a suitable sampling program is created, taking into account the cost of work, the quality and quantity of samples and the resulting measurements, the urgency of the data and the safe practice. If the fluids are under pressure or not, it will also determine the sampling procedures which are 1) downhole fluid sampling 2) Surface sampling of reservoir fluids 3) Nonpressurized hydrocarbon fluid sampling 4) Oilfield water sampling
