Method for determining the effective porosity of a reservoir-rock. State College, Pa., School of Mineral Industries, (OCoLC) Document Type: Book: All Authors / Contributors: Kenneth Boyd Barnes. One of the methods which shape of the pore is determined by is the optical microscope. Images must have significant contrast to distinguish objects to be analyzed from the rest of matrix. It is possible to calculate the porosity percentage by using Eq. 3 . WELL LOGS Openhole logging tools are the most common method of determining porosity: Less expensive than coring and may be less risk of sticking the tool in the hole Coring may not be practical in unconsolidated formations or in formations with high secondary porosity such as vugs or natural fractures.5/5(1). To determine your hair’s porosity you need to observe how quickly your hair gets wet. High porosity hair will absorb water quickly because the cuticles are open, and therefore, your hair will get wet very quickly. Low porosity hair takes a long time to get wet and repels water because the cuticles are almost closed. Medium porosity falls in between.
Aim of Experiment: In this test we will try to determine the porosity by using the saturation method. 3. Introduction Knowledge of the physical properties of the rock and interaction between hydrocarbon system and the formation rock is crucial in understanding and evaluating the performance of a given reservoir. —The method is in general applicable to pieces of any size and shape and to all classes of porous bodies or materials. A new porosimeter.—For rapid work with shaped test pieces a new porosimeter is described. The new instrument measures accurately both pore volume and bulk volume. A complete porosity determination can be made in 5 by: A Method for Determining the Effective Porosity of a Reservoir Rock by Kenneth B Barnes, , available at Book Depository with free delivery worldwide. Suggested Methods for Determining Water Content (viii) Determination of pore volume (volume of voids) W Saturation method--the pore volume of a rock sample may be determined from the difference between saturated-surface-dry and oven-dry masses. The sample is saturated by water immersion in a vacuum and itsFile Size: 1MB.
The purpose of this study is threefold: to experimentally evaluate the factors controlling the porosity and permeability of ideal clastic materials; to determine the modifications produced in natural deposits by variations from the ideal; to apply the principles of permeability to the problem of the distribution and localization of mineral deposits in clastic by: Clearly this method also measures the connected porosity. In practice there is always a small pore volume that is not accessed by the mercury even at the highest pressures. This is pore volume that is in the form of the minutest pores. So the mercury injection method will give a lower porosity than the two methods described above. Coming from a CT (computed tomography) background, I would say that it is a good technique to determine porosity inside a specimen. The wide range of pore sizes . to - The Blue Book.
