Reservoir Fluid Properties PEEG 216 Fluid Type Rules: Reservoir fluids are often subdivided into five fluids types (Chapter 5) Shape of the diagram depends on composition Fluid type depends on reservoir pressure and temperature Beware: Once the reservoir enters the two- phase region, one fluid is produced preferentially, which changes the composition, and thus the phase diagram.

Reservoir Fluid Properties PEEG 216 Saturation Status A saturated reservoir is one where the reservoir pressure is equal to bubble point or dew point pressure (it usually indicates the fluid is in equilibrium with a gas cap or oil leg somewhere) An under-saturated reservoir exists at a pressure above bubble point or dew point. Production starts with expansion drive until saturation pressure is reached. The word saturated refers to the idea that an oil fluid is “full of gas” (there is at least one bubble that cannot dissolve), and similarly for a gas fluid.

Reservoir Fluid Properties PEEG 216 Main Two Fluid Types If T c > T res , the fluid is called an oil If T c < T res , the fluid is called a gas So these are clear-cut definitions…. except that: If T c ≈ T res , the fluid is critical or near-critical fluid The critical temperature is a function of the composition of the fluid. Its relation to the reservoir temperature determines fluid type experimentally.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
