Introduction : Saturation is defined as that fraction, or percent, of the pore volume occupied by a particular fluid (oil, gas, or water). This property is expressed mathematically by the following relationship: fluid saturation = total volume of fluid / pore volume Applying the above mathematical concept of saturation to each reservoir fluid gives : So = vol of oil / pore vol Sg = vol of gas / pore vol Sw = vol of water / pore vol where S o  oil saturation S g  gas saturation S w  water saturation Thus, all saturation values are based on pore volume and not on the gross reservoir volume. The saturation of each individual phase ranges between zero to 100 percent. By definition, the sum of the saturations is 100%, therefore S g  S o  S w  1.0 The fluids in most reservoirs are believed to have reached a state of equilibrium and, therefore, will have become separated according to their density . To determine the quantity of Hydrocarbons accumulated in porous rock formation ( OIIP

### What students are saying

• 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.
