    The greater the tortuosity the lower the permeability because viscous resistance is cumulative along the length of the pathway. Topic 8: Water and Climate.

    Porosity is determined by: 1. Presentation on theme: "Porosity, Permeability,"— Presentation transcript:. If porosity measurements are very important, both coring and logging programs may be conducted so the log-based porosity calculations can be used to calibrated to the core-based porosity measurements. Smaller pathways reduce porosity and the size of the pathways so the more tightly packed the sediment the lower the permeability.

    Start on.

    Fractures can greatly enhance permeability but do not increase porosity significantly.

    In general, the greater the angularity of the particles the more open the framework more open fabric and the greater the possible porosity. Fine sand has slightly higher porosity.

    I agree. In very well sorted sands the pore spaces are open. Auth with social network: Registration Forgot your password?

    Slope of the water table; Permeability of the rock or sediment. Porosity and Permeability. Porosity - the percentage of rock that consists of voids or openings. Definition: Porosity is the fraction of a rock that is occupied by voids (pores).

    Discussion Factors that effect porosity.

    Methods of. Significant Permeability. Porosity - The amount of space in between sediments. Porosity is determined by: 1. Shape - Well rounded particles have greater porosity than angular. ROUND.

    Cementing of particles by ice. Like this presentation? Fabric preferred orientation of the grains in a sediment can cause directional permeability. Fine sand is angular, with sharp edges, and the edges will break under the load pressure and become more compacted more tightly packed with lower porosity.

    Solution is the most effective means of creating secondary porosity.

    For clay-free sands the reduction in porosity with increasing sorting coefficient is greater for coarse sand than for fine sand. In this case, assume that the pore spaces of the sediment in the oilbearing unit are full of oil. The direction along the long axes of grains will have larger pathways and therefore greater permeability than the direction that is parallel to the long axes.

    The difference is unlikely if clay was also available to fill the pores. The Water Cycle Climate — the conditions of the atmosphere over long periods of time Water cycle — the movement and phase.
