... behavior is mainly linear-elastic with a brittle-to-ductile transition. Type-2 behavior is linear-elastic, until a brittle-to-ductile transition, and develops dilatant plastic strain prior to failure. Type-3 behavior is linear-elastic up to the onset of compaction, which occurs at low mean stress. Results...

... contains a proven reservoir in Cycle 1; however, the time equivalent in the northern part of the basin is not yet well understood. This work represents a high-resolution comparison of lithology, clay abundance, compaction, cementation, grain assemblage, total organic content, porosity and pore morphology...

.... Our results suggest that porosity loss through mechanical compaction is effectively complete in shales by a depth of 6500-7000’ (~2 km). The continued decreasing log-based porosity with depth might be due to mechanical and chemical compaction other types of rocks (e.g., shaley siltstones, thinly...

... for permeability decline. To further understand the impact of proppant size on permeability, dry crush tests have been conducted on 20/40 and 60/100 Ottawa sand by varying compaction pressure from 1500 psi to 3000 psi and 5000 psi. We observed that 60/100 mesh sand undergo overall higher compaction and crushing...

... shales have a porosity/effective stress relationship that can be used to link the mechanical compaction of the rock to the pore pressure via the vertical stress (overburden). Shales in unconventional plays have variable clay contents, are uplifted, are affected by chemical processes and diagenetic...

... more than 250% times larger, when temperature increased from 20 centigrade to 550 centigrade. The process of porosity evolution can be divided into three phases. Firstly, porosity decreased rapidly from immature to low mature stage because of weak hydrocarbon generation and strong compaction; Secondly...

However, due to extreme stress/heat generated during the explosion, near wellbore region might reach plastic flow and/or compaction limit.
