Field observations show that less than one percent of dissociation water can be produced during gas hydrate production, resulting from spontaneous water imbibition into matrix pores. What’s more, the hydrate sediments are easily dispersed in water,

Microscopic imbibition characterization of sandstone reservoirs and theoretical model optimization
Traditional porous media imbibition models deviate from the actual imbibition process in oil and gas reservoirs. Experimental studies on gas–water imbibition in reservoirs were carried out to describe the dynamic profile variation process of wet phase ...

Experiments on imbibition mechanisms of fractured reservoirs by microfluidic chips
To solve the problems of long experiment period and difficult measurement in core imbibition experiments, fracture—matrix microfluidic chips of different sizes, boundary conditions and wettability regulated by surface property modification were designed ...

In order to investigate the characteristics of water displacement and adsorption of gas along the original cracks and pores of coal under the action of water-thermal coupling, imbibition experiments of 50 mm×100 mm columnar raw coal were carried out for ...

Imbibition of water and silicone oil in poplar and spruce is investigated at the anatomical level by X-ray tomography observations and at the macroscopic level by imbibition kinetics. Imbibition mechanisms depend on both liquid and species.

Core-scale modeling of surfactant-assisted spontaneous water imbibition in carbonates
This work numerically investigates surfactant effects on spontaneous water imbibition in oil-wet carbonates. An open boundary core-scale imbibition model with 9 × 9 × 10 gridblocks was used in UTCHEM to simulate carbonate core plug exposure to a vast ...

Effect of Particle Size on Droplet Infiltration into Hydrophobic Porous Media As a Model of Water Repellent Soil [PDF]
The wettability of soil is of great importance for plants and soil biota, and in determining the risk for preferential flow, surface runoff, flooding,and soil erosion. The molarity of ethanol droplet (MED) test is widely used for quantifying the severity

Abnormal Phenomena and Mathematical Model of Fluid Imbibition in a Capillary Tube
At present, the imbibition behavior in tight rocks has been attracted increasing attention since spontaneous imbibition plays an important role in unconventional oil and gas development, such as increasing swept area and enhancing recovery rate. However,

Dynamic Pore-Scale Network Modeling of Spontaneous Water Imbibition in Shale and Tight Reservoirs
Spontaneous water imbibition plays an imperative role in the development of shale or tight oil reservoirs. Spontaneous water imbibition is helpful in the extraction of crude oil from the matrix, although it decreases the relative permeability of the ...
