High pressure and temperature
A custom designed pressure PVT cell for fluids collected high pressure and\or temperature reservoirs (maximum pressure: 20.000psig & maximum temperature: 200 c)
Viscosity is determined using an electro‐magnetic viscometer (EMV) developed by Cambridge instruments. This instrument is based on a patented technique in which magnetic force is applied to a piston immersed in the fluid under test. Motion of the piston is resisted by viscous drag of the fluid and the equipment is checked annually using pure component or synthetic fluids viscosity and density properties.
Range 0.02 to 10.000cp, maximum pressure 20.000psig, and maximum temperature: 190c, all fluid types.
Equipment is calibrated at regular predefined intervals in accordance with documented procedures.
A high pressure PAAR density meter is ulized for densies up to 20.000 psig and 200c.
Lean gas condensates
During a constant composition expansion (CCE) experiment of gas condensates the retrograde liquid volume should be measured until a maximum liquid drop out is achieved. Using conventional PVT equipment this is only possible by introducing a smaller sample volume (30cm3) the smaller the sample size the less retrograde liquid volume there is and therefore the larger the error in the measurement. This error is increased for very lean condensates.
Core laboratories utilize specialized large volume PVT cells which allow an initial sample size of up 300 cm3to be introduced. A unique piston design, in conjunction with the small visual window and video capture system. Enables accurate retrograde liquid measurements to be determined at any pressure during the CCE experiment
