Real-Time Pore Pressure Detection: Indicators and Improved Methods

open access: yesGeofluids, 2017
High uncertainties may exist in the predrill pore pressure prediction in new prospects and deepwater subsalt wells; therefore, real-time pore pressure detection is highly needed to reduce drilling risks.

Using a novel approach to determine the pore pressure of West Qurna 15 oil well in South of Iraq

open access: yesJournal of Engineering, 2020
Pore pressure means the pressure of the fluid filling the pore space of formations. When pore pressure is higher than hydrostatic pressure, it is named abnormal pore pressure or overpressure.

Seepage and stability analysis of pore air pressure on a high-bench dump under heavy rainfall

open access: yes工程科学学报, 2021
Under heavy rainfall, the pore air pressure in the unsaturated zone of a dump hinders rainwater infiltration in loose soil, which further affects the safety and stability of the dump.

Development of a pore gas pressure transducer used in unsaturated soils at high water content [PDF]

open access: yesE3S Web of Conferences, 2019
Pore gas pressure in soil is an important parameter in many geoscience applications such as evaluating the effects of trapped pore gas pressure on water infiltration through soil mass, optimizing the design of gas extraction wells in landfills and ...

Effect of hydrogel particle additives on water-accessible pore structure of sandy soils: A custom pressure plate apparatus and capillary bundle model [PDF]

open access: yes, 2013
To probe the effects of hydrogel particle additives on the water-accessible pore structure of sandy soils, we introduce a custom pressure plate method in which the volume of water expelled from a wet granular packing is measured as a function of applied ...

Field monitoring of pore water pressure in fully and partly saturated debris flows at Ohya landslide scar, Japan [PDF]

open access: yesEarth Surface Dynamics
The characteristics of debris flows (e.g., mobility, sediment concentration, erosion, and deposition of sediment) are dependent on the pore water pressure in the flows.
