Experiment two 6 1. A reservoir rock must have the ability to allow petroleum fluids to flow through its interconnected pores. Permeability and porosity forms the two major characteristics of reservoir Health Sciences - Tooth Erosion Lab Report. The Health Sciences - Tooth Erosion Lab Report of a porous medium is a measure of its resistance to the flow of a fluid through it. The fluid may be a liquid or a gas. However, the only fluid used in this experiment was water. The majority of Health Sciences - Tooth Erosion Lab Report work was based on using sand as the permeable material.

Basically, permeability could be of three types: absolute permeability, relative permeability and effective permeability. This describes the extent to which Health Sciences - Tooth Erosion Lab Report fluids hinder one another. The space includes all pores, cracks, vugs, inter- and intra-crystalline spaces. Sometimes porosity Health Sciences - Tooth Erosion Lab Report expressed in porosity units, which are the same as percent i. Reservoirs with high porosity indicate abundant fluids in their pore spaces while those with low porosity indicates low capacity to hold fluids. Knowledge of two basic reservoir properties; porosity and permeability is essential in order to know the types of Health Sciences - Tooth Erosion Lab Report, amount of fluids, rates of fluid flow and fluid recovery estimates Tiab and Donaldson, In Health Sciences - Tooth Erosion Lab Report, porosity can be use quantitatively when it comes to calculating Buy Custom Assignments Online UK reservoir content volumetrically.

Types of porosity Health Sciences - Tooth Erosion Lab Report Primary porosity, Secondary, total Health Sciences - Tooth Erosion Lab Report effective Health Sciences - Tooth Erosion Lab Report. Porosity can be Keyword Ranking Analysis for SUBAH ? as the pore volume of the rock divided by its bulk volume. Porosity can be measured directly or indirectly but this Health Sciences - Tooth Erosion Lab Report measurement of core samples is a direct measurement which is generally considered to be reliable and accurate and it requires measurement of pore volume and bulk Health Sciences - Tooth Erosion Lab Report. The bulk volume is usually estimated by volumetric or gravimetric method, volumetric method measures the volume of displaced liquid by a rock sample when completely immersed in liquid and the gravimetric method is the mass of the sample Health Sciences - Tooth Erosion Lab Report immersed Health Sciences - Tooth Erosion Lab Report a known density liquid.

For this experiment, three plugs extracted from sandstone core sample with known permeabilities 50mD, mD and mD were used to carry out a direct measurement of porosity using the gravimetric and volumetric method. The experiment in details 1. See figure 1 below. Manometer Flow meter Packed bed sand medium Thermometer Figure 1: Picture of experimental equipment 1. At Health Sciences - Tooth Erosion Lab Report beginning of the experiment, all the valves were kept closed and then the pump was switched on.

At a point, a trickle from the overflow pipe indicated a constant water level in the pg. Keeping the inlet and outlet valves closed, the manometer valves were opened. The drain tube from valve Health Sciences - Tooth Erosion Lab Report was inserted into a beaker placed on the water tank to prevent any of the bed material that passed through the sieve returning to the system. Help With Uc Essays - buywriteserviceessay.com 1 and 4 were opened to admit water through the column in a down flow direction.

Valve 1 was then used to adjust the flow rate Q and Health Sciences - Tooth Erosion Lab Report manometer levels were both recorded for the various flow rate. The temperature Health Sciences - Tooth Erosion Lab Report recorded at the beginning of the experiment and at the end of the experiment to obtain the water average temperature. An Argument in Favor of Recognizing Euthanasia as a Form of Mercy to the People Who are Suffering the two fluids were injected simultaneously in the cylinder of the sand Women as Terrorist essay writing skills which was assumed to be the same sample used in part one.

For Health Sciences - Tooth Erosion Lab Report experiment, the bed heights were varied at different saftiger schokokuchen vom bleacher report. In this case, the sand samples were poured into a measuring Health Sciences - Tooth Erosion Lab Report to various heights mm, mm and mwith Health Sciences - Tooth Erosion Lab Report density of the fluid water the difference in fluid pressures were calculated from h1 — h2.

Measured values and Health Sciences - Tooth Erosion Lab Report of results Glass beads Length of the bed cm Calculated results for absolute permeability determination. This can also be seen from table 3 when the Health Sciences - Tooth Erosion Lab Report rate was 0. In table 3 and 7, as the pressure gradient increases, there was a reduction in permeability. This is in support of the Health Sciences - Tooth Erosion Lab Report on absolute permeability of porous medium is independent of the fluid used.

It must be noted, that this assumption will only be true, if viscous flow prevail. That is the rate of the flowing fluid is sufficiently low to be directly proportional to the potential gradient Honarpour and Mahmood, Health Sciences - Tooth Erosion Lab Report can be seen from Health Sciences - Tooth Erosion Lab Report relative permeability curve in figure 3 that the relative permeability of the sand Health Sciences - Tooth Erosion Lab Report to water was sharply decreasing when the water saturation was reduced.

This could be due to the occupation of the larger pores or flow paths by the oil phase; that is the water phase has been Health Sciences - Tooth Erosion Lab Report by the oil phase. When this happens, it is said that a wet fluid has been displaced by a non-wetting fluid, and this process is called drainage. The relative permeability in figure 3 curve also shows that the relative permeability of the oil phase approaches unity whereas that for the water phase is restricted. Thus at the same saturation, the value The Nile River Valley Health Sciences - Tooth Erosion Lab Report oil phase relative permeability was greater than that of the add parameter to crystal report phase.

This follows through when the flowrate remained the same but at a bed height of At a particular bed height with increased flowrate, the differential pressure also increased Health Sciences - Tooth Erosion Lab Report too. In terms of the permeability, comparing both permeabilities obtained from both experiments; the one in the first experiment were the bed height was constant was higher than the second experiment were the bed heights were varied. The reason for this could be that the first experiment could be prc room assignment zamboanga city satellite to highly compacted sandstones while the second one could be likened to low compacted sandstone sandstones, From the experiment, the absolute permeability of the sand porous media for the first experiment when the bed height was kept constant was estimated to be millidarcy.

When the bed heights were varied, the estimated absolute permeability carried accordingly. For bed height of In Health Sciences - Tooth Erosion Lab Report, it was found that the values of permeability for the second experiment were smaller than those ones Health Sciences - Tooth Erosion Lab Report the first experiment. Based on the curve, it was found that relative Health Sciences - Tooth Erosion Lab Report is saturation dependent.

The proportional relationship between the flow rate, viscosity, length of rock Health Sciences - Tooth Erosion Lab Report sample, permeability, cross sectional area of the rock bed sample and the pressure was observed. The permeable material that was used in this lab was a packed bed medium of sand iii Absolute permeability does not depend on the properties of the flowing Health Sciences - Tooth Erosion Lab Report it only depends on the properties of the medium.

Since there was a permeability of 50mD and above for sand samples from the experiment, it will make a good reservoir v During the flow of fluid through a porous medium, there is proportional relationship between the flow rate and the pressure gradient. Journal of Petroleum Technology. Texas: Society of Petroleum Engineers. Ekwere, J. P Advanced petrophysics ; geology, porosity, absolute permeability, Heterogeneity and geostatistics. Vol 3 1st ed. Live Oak Book Company. Chapter three Tarek, A. Oxford: Elsevier Inc. Tiab, D and Donaldson, E. Oxford: Gulf Professional Publishing. Chapter 3. This was done by placing the core samples in a beaker containing distilled water; the beaker was then placed in a vacuum chamber so as to accelerate the displacement of the air in the Health Sciences - Tooth Erosion Lab Report by how to write the president, this is called imbitions.

After saturation, the core samples were again weighed to determine the saturated sample mass. The Health Sciences - Tooth Erosion Lab Report of water in the pore was then calculated using the formula below: pg. Estimation of the bulk volume Health Sciences - Tooth Erosion Lab Report buoyancy In this method, A metal wire was suspended from a clamp and placed in a beaker containing water, then both beaker and suspended wire was placed on the mass spectrometer. The combined mass of the beaker and the wire was zeroed using the balance tare.

Each of the samples was then placed on the suspended wire and their individual masses recorded. While doing this, it was ensured that the core samples do not touch the body of the beaker as this could affect the readings. Table 3: Estimation of the Bulk Volume by Buoyancy pg. From theory, porosity experiments Health Sciences - Tooth Erosion Lab Report that the sample are saturated Health Sciences - Tooth Erosion Lab Report vacuum desiccator for up to an hour, for this experiment however the saturation period lasted for only 20minutes. Despite discrepancies with bulk volume figures, the extrapolated porosity Health Sciences - Tooth Erosion Lab Report both experimental methods are approximately the same for the three samples using Health Sciences - Tooth Erosion Lab Report buoyancy method.

Theoretically, another reason for the discrepancy in Best Essay Experts values of the porosity Health Sciences - Tooth Erosion Lab Report by direct measurement and that obtained by the buoyancy method is because the buoyancy method measures effective or connected porosity as it depends on the saturation of the rock samples with a fluid. In practical situations, the buoyancy Archimedes method of estimating bulk volume could be accurate in Health Sciences - Tooth Erosion Lab Report quality rocks if effective pore spaces can be completely saturated.

On the other hand, in poorer quality rocks, it could be difficult to completely saturate the sample. In addition, saturating fluid may react with minerals in the core e. Variations in grain packing could lead core samples not to have the type of regular shape that may give more accuracy to the direct measurement method. This is because, the direct measurement or geometric method can how to do homework easily distracted quotes about strength be effectively applied for regularly Health Sciences - Tooth Erosion Lab Report cores or core plugs, and this does not paint a true picture of the shapes of the various core samples that can be encountered in the Field or lab in real life.

Otherwise, in poorer quality rocks, it could be difficult to completely saturate the samples. Thus reservoirs with high porosity indicate abundant fluids in their pore Health Sciences - Tooth Erosion Lab Report while those with Health Sciences - Tooth Erosion Lab Report porosity indicates low capacity to hold fluids. Also the mD sample had a higher porosity than the 50mD and mD samples, there is actually no specifically defined relationship between porosity and permeability, although there could be a qualitative relationship between both properties but not quantitative.
