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 ...

As operators plunge into deeper formations - many below 30,000 ft - ensuring hole size at total depth (TD) can be challenging. In the Gulf of Mexico, salt and sub-salt zones, pore pressure/frac ...

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, ...

Texaco Inc. is drilling what it says is the first dual-gradient well using a subsea-mudlift drilling system developed by a joint industry project led by Conoco Inc. The Shasta field No. 8 is in 910 ft ...
