To clarify the influence of pore pressure gradient on hydraulic fracture propagation, the stress distribution in and around the borehole is explained by theoretical analysis method in this paper. A ...

Wireline logging—specifically wireline formation testing and pressure surveys—provides direct, depth-referenced measurements of in-situ reservoir pressure and fluid gradients, the backbone of ...

The petroleum industry must predict pore-pressure profiles accurately, often walking a fine line between pore pressure and fracture gradient as it drills and completes oil and gas wells. The industry ...

WASHINGTON, DC—Invasive hemodynamic assessment may help better identify severe aortic stenosis in patients with low aortic flow/low transvalvular pressure gradients and preserved ejection fractions, ...
