EXECUTIVE SUMMARY In the following experiment entitled “Fluid Saturation”, the students had to clean the core plug for the conventional core analysis by removing the saturated fluids via the solvent Toluene. In the second half of the experiment, we had to use the Dean-Stark distillation technique to determine the amount of saturated fluids in the saturated core. Next we had to weigh the core plug that was saturated in brine and oil. After that, we then placed the core sample into the Soxhlet Extractor and the extractor collected any of the condensed brine and oil. You then use that information, as well as the densities of Toluene, the brine, and the oil, to determine the overall porosity of the core sample in which we were given. Then, we weighed the core sample after it was immersed in Toluene and the water and brine had been extracted. Finally, my group and I placed our saturated core into an oven for 24 hours to fully dry. After that, we took out the core and weighed it; this value was it’s dry weight. Once we had all of this data, we could then complete the rest of the calculations on our data sheet. In the following experiment entitled “Porosity”, the students had to calculate the effective porosity of our given core sample. To do so, we had to use a Vernier Caliper, Electronic Balance, & a Helium Porosimeter. Each group was given a lab set number and we had to record this number on our data sheet. The number that we were given corresponds to a certain billet’s marked A,B,C,D and E. Each billet was a different size and shape. At first, we measured the core sample’s length and diameters via a Vernier Caliper. We then took three reading of the length and averaged them, and then we did five readings of the diameter and averaged those. After all of that, we used setup number four and our first objective was to find the original and final pressure of just the billet that we were assigned. The next step was to place our given core in place of several billets so that the billets and core would be flush with the top of the contraption. Then, we did the - i -

first part and found the original pressure and the final pressure. Finally, we put our core in place of two billets and repeated the experiment and wrote down our pressure for this facet of the experiment. We then compared these two initial and final pressures to the bulk volume from experiment three and we calculated various porosities. In the following experiment entitled “Gas Permeability”, our objective was the determine the permeability of our given core sample by injecting Nitrogen throughout the core. At first, we injected several different amounts of pressure such as 20 psig, 30 psig, etc. and controlled how much pressure was used via a Gas Permeameter. Our first step in this experiment was to measure the overall temperature and pressure of the room in Fahrenheit and mm Hg respectively.

    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.
