Reduction of Permeability in Granite at Elevated Temperatures

Science, 1994
The addition of hydrothermal fluids to heated, intact granite leads to permeability reductions in the temperature range of 300° to 500°C, with the rate of change generally increasing with increasing temperature. The addition of gouge enhances the rate of permeability reduction because of the greater reactivity of the fine material.

A New Approach to Permeability Reduction

Journal of Petroleum Technology, 1975
Introduction There are many published schemes for reducing the permeability of reservoir rock. The method described here permeability of reservoir rock. The method described here involves plugging interpore connections with colloidal particles. The novelty of this method is the chemistry of particles. The novelty of

Aquifer recharge using a partially penetrating well with clogging-induced permeability reduction

, 2020
Well and aquifer clogging is one of the most serious problems restricting the application of managed aquifer recharge (MAR). To address the clogging issue, this study proposes an innovative model using partially penetrating wells (PPW) in confined ...

Reduction in Permeability With Overburden Pressure

Journal of Petroleum Technology, 1952
Oil bearing rocks, usually found at depths of 2,000 to 10,000'Ft, areelastically deformed by overburden pressure. Although the change in porositywith pressure in a number of example rocks has been shown to be small, it wasthought that overburden pressure might have a significant effect onpermeability.

Permeability Reduction by Treatment With KUSP1 Biopolymer

SPE Journal, 2000
Summary The application of KUSP1 biopolymer for use in permeability reduction treatments of oil reservoirs was investigated. KUSP1 is a nontoxic polysaccharide that is produced by a bacterium. Alkaline solutions of KUSP1 have low viscosities and can be gelled by different methods. Three methods were examined to gel KUSP1 in porous media.

Analysis of permeability reduction in drainage asphalt mixtures due to decrease in void volume

, 2020
Pavements with a wearing course of drainage asphalt mixtures have been used in regions with high rainfall due to their ability to remove stormwater from the surface and increase the tire-pavement adhesion. However, over time, due to traffic flow together

Mechanistic Study of Disproportionate Permeability Reduction

Proceedings of SPE/DOE Improved Oil Recovery Symposium, 1998
Abstract It is a common observation that gels in a porous media reduce the permeability to water more than that of oil. Core floods on sand packs using well defined model media has been carried Out to elucidate the matter.

An experimental investigation of the effect of long-term, time-dependent proppant embedment on fracture permeability and fracture aperture reduction

International Journal of Rock Mechanics And Mining Sciences, 2021
The inability to achieve satisfactory production targets from unconventional oil/gas deposits is a foremost concern for many hydraulic fracturing projects.

Microfluidic Study of Polymer Permeability Reduction Mechanisms

SPE Annual Technical Conference and Exhibition, 2022
Abstract Polymer solutions see broad applications in hydraulic fracturing, enhanced oil recovery, conformance control, and groundwater remediation. However, due to the high viscosity of polymer solutions, flows after polymer injection are often subjected to significant pressure build-up, the mechanism of which is not well studied ...
