WebFeb 14, 2024 · Deposits of unconsolidated sediments typically have high porosity — pores are open spaces between grains filled with gas or fluids (water or in some cases, petroleum). Compaction is the process of gravitation consolidation of sediments, decreasing the volume of pore space between particles of sediment and increasing hardness. WebPorosity values were determined for two packings, designated as “dry-loose” and “wet-packed.” Porosity data for “wet-packed” sand samples remain about the same for …
Direct determination of porosity by core analysis is the "gold standard" and is used where available to calibrate all indirect measurements. Indirect methods allow leveraging of limited core data to provide more information on areal and vertical variations in porosity when coring is too expensive and/or only … See more If one has access to an undamaged whole core from the reservoir in question, direct measurement of the porosity is possible, if care is taken. Some profess that all cores are damaged by the … See more Different logging tools can provide different types of insight to assist in calculating porosity. The best method may be to rely on a combination of approaches where the information is available. 1. Acoustic logging 2. … See more The dual-porosity system that exists in a fractured matrix reservoir provides a challenge in the opposite direction in that often the overall value of porosity is quite low (2 to 3%). … See more Use this section to list papers in OnePetro that a reader who wants to learn more should definitely read See more http://www-odp.tamu.edu/publications/190196SR/355/355_5.htm

WebAfter retrieving representative core samples and delivering them to the laboratory, there are several methods that can be used to determine porosity. As shown in Equations 3.01 through 3.03, to determine porosity, we need to determine two of the three volumes, V b, V p, or V g. Once these are determined, then the porosity and the third volume ...
