INVERSE MODELING OF SPONTANEOUS IMBIBITION

, 2023
Reservoirs that contain natural fracture systems, often developed through water injection, comprise a significant portion of the global oil supply. The injected fluid tends to flow preferentially through the fracture network, thereby bypassing the matrix

Spontaneous imbibition experiments for enhanced oil recovery with silica nanosols [PDF]

, 2023
Experimental oil displacement as a result of spontaneous imbibition of silica nanosols has been carried out using two types of sandstone as the reservoir rock.

Measurement of Spontaneous Imbibition Capillary Pressure, Saturation and Resistivity Index by Counter Current Technique at Net Reservoir Stress and Elevated Temperature [PDF]

E3S Web of Conferences, 2019
Capillary pressure and resistivity index spontaneous imbibition experiments by the porous plate method, in a core holder at elevated temperature and net reservoir stress, are both difficult and time consuming special core analysis measurements to perform.

Spontaneous imbibition in asymmetric branch-like throat structures in unconventional reservoirs

, 2017
Unconventional reservoirs, especially shale plays, have abundant micro nano pores. Large volume water was injected into the reservoir during hydraulic fracturing.

Microcalorimetric Study of Carbonating Produced Water as a Promising CO₂ Storage and Enhanced Oil Recovery Method

Energies, 2022
Carbonated produced water injection (CPWI) might be considered an efficient alternative to handle the largest waste stream while enhancing the oil recovery and storing carbon dioxide (CO2) underground.

Dynamic Pore-Scale Network Modeling of Spontaneous Water Imbibition in Shale and Tight Reservoirs

Energies, 2020
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 ...

Simulation of pore-scale microscopic spontaneous imbibition of shale based on level-set method

Youqi dizhi yu caishoulu
The core pore structure of the target shale oil block was finely characterized using scanning electron microscopy， and a microscopic numerical model of the pore-scale core was constructed to elucidate the intrinsic mechanisms and the main controlling ...

Elevated liver enzymes is not an impediment to allopurinol dose escalation: an observational cohort study

Arthritis Care &Research, Accepted Article.
Objective Routine liver enzyme monitoring is advocated while on allopurinol but supporting guidance is lacking. We assessed the incidence and factors associated with elevated liver enzymes in gout patients commenced on allopurinol. Methods 150 patients with gout and normal baseline serum aminotransferases initiated on allopurinol were followed ...

Enhancing the spontaneous imbibition rate of water in oil-wet dolomite rocks through boosting a wettability alteration process using carbonated smart brines

Petroleum Science, 2019
Most fractured carbonate oil reservoirs have oil-wet rocks. Therefore, the process of imbibing water from the fractures into the matrix is usually poor or basically does not exist due to negative capillary pressure.
