An Evaluation of Rock Integrity and Fault Reactivation in the Cap Rock and Reservoir Rock Due to Pressure Variations
Cap rocks are dams which can prevent the upward movement of hydrocarbons. They have disparities and weaknesses including discontinuities, crushed areas, and faults. Gas injection is an effective mechanism for oil recovery and pore pressure. With increasing pore pressure, normal stress is reduced, and the integrity of impermeable boundaries (cap rock, fault, etc.) becomes instable. A successful ...
متن کاملImage analysis for quantification of bacterial rock weathering.
A fast, quantitative image analysis technique was developed to assess potential rock weathering by bacteria. The technique is based on reduction in the surface area of rock particles and counting the relative increase in the number of small particles in ground rock slurries. This was done by recording changes in ground rock samples with an electronic image analyzing process. The slurries were p...
متن کاملRock and Mineral Weathering Experiments under Model Venus Conditions
Introduction. Chemical analyses of rock and rego-lith at the Venera and Vega landing sites [1] suggest that Venus' surface consists of basaltic rocks with variable amounts of S, either as a primary constituent or as a secondary product of atmospheric interactions. Starting with these chemistries, models of Venus mineralogy predict that the surface is composed of primary basaltic minerals, unrea...

متن کاملDraft Genome Sequence of Rhizobium sp. H41, a Rock-Weathering Bacterium from a Weathered Rock Surface
Rhizobium sp. H41 isolated from weathered tuff can weather tuff and release Fe, Si, and Al from the rock under nutrient-poor conditions. Here, we report the draft genome sequence of strain H41, which may facilitate a better understanding of the molecular mechanism involved in rock weathering by the bacterium.
