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 ...

Compared to conventional vertical wells, complications from formation pore pressure, borehole stability, hole cleaning, drillstring torque and drag, and other parameters create serious challenges for ...
