This chapter discusses building a rock stress log, what assumptions are made, and how to minimize uncertainty. Pore pressure and calculations on how to determine effective in situ stress are included. How everything in fracturing flows from in situ stress, how/why this

pore pressure | Oilfield Glossary

pore pressure. 1. n. [Geology] The pressure of fluids within the pores of a reservoir, usually hydrostatic pressure, or the pressure exerted by a column of water from the formation's depth to sea level. When impermeable rocks such as shales form as sediments are compacted, their pore fluids cannot always escape and must then support the total overlying rock column, leading to anomalously high

Effects of pore and differential pressure on compressional

ing and pore pressures up to 55 and 35 MPa, respectively. The pressure limits were defined by the aluminum sample holder, electrical contacts, and the epoxy used in the anvils. The sam-ples were saturated under a vacuum with 60 ppm brine prior to loading into the assembly. Traveltimes were measured on the oscilloscope by digitizing a trace with 1024 points at a time sweep of 5 „s, thus

6. THE BOREHOLE ENVIRONMENT 6.1 Introduction 6.2

The overburden pressure acts upon a rock to crush it. The fluids in the pore spaces would then be compressed. Hence, the fluid pressure acts on the rock to stop the rock crushing. The fact that the rock does not crush under the overburden pressure, is the combined result of the inherent strength of the rock grains and any cementation, and the strengthening effect of the fluid pressure. A total

Pore pressure is calculated as the difference between overburden stress and effective stress. The effective stress affects the grain-to-grain contacts and consequently, the velocities of seismic waves propagating through the rock (Domenico, 1984; Dutta, 1997). The rock model used in the present work is based on the general rock physics principles discussed in Part 1 (Mukerji et al 2002). It

Effective pressure or what is the effect of pressure?

and pore pressure have the same effect on permeability and velocities. In contrast, rocks with low porosity are influenced more by changes in confining pressure than by changes in pore pressure. Therefore the effective-pressure coefficient is smaller than one. When the effective-pressure coefficient approaches zero, the pore pressure has no influence on deformation, velocity, or permeability

Gravel / ˈ ɡ r æ v əl / is a loose aggregation of rock fragments. Gravel is classified by particle size range and includes size classes from granule- to boulder-sized fragments.In the Udden-Wentworth scale gravel is categorized into granular gravel (2 to 4 mm or 0.079 to 0.157 in) and pebble gravel (4 to 64 mm or 0.2 to 2.5 in). ISO 14688 grades gravels as fine, medium, and coarse with
