Abstract
The disclosure describes a system to segregate, enrich and capture oil, water and gas samples from a multiphase flow. The system can be used in a subsea location, on the surface or in any other condition where it is connected to a flow of different phases of gas and/or liquid. The samples obtained are representative in composition of the phases flowing at well head conditions in terms of both pressure and temperature. Additionally, a relatively small volume of each phase is used in obtaining the samples. The system connects and disconnects to ports installed at the sampling location nearby the wellhead or the production line. The sampling flow is controlled by means of a pump. The collected samples are separated in mono (or nearly mono)—phase samples (oil, water and gas) and stored in individual bottles.
