Frontier Enhanced Oil Recovery (EOR) Research on the Application of Imbibition Techniques in High-Pressure Forced Soaking of Hydraulically Fractured Shale Oil Reservoirs

Geofluids, 2021
Shale reservoirs are characterized by low porosity and low permeability, and volume fracturing of horizontal wells is a key technology for the benefits development of shale oil resources. The results from laboratory and field tests show that the backflow

Microbial analysis of backflowed injection water from a nitrate-treated North Sea oil reservoir

Journal of Industrial Microbiology & Biotechnology, 2009
Reservoir souring in offshore oil fields is caused by hydrogen sulphide (H(2)S) produced by sulphate-reducing bacteria (SRB), most often as a consequence of sea water injection. Biocide treatment is commonly used to inhibit SRB, but has now been replaced by nitrate treatment on several North Sea oil fields.

Diffusiophoresis in non-adsorbing polymer solutions: the Asakura-Oosawa model and stratification in drying films [PDF]

, 2017
A colloidal particle placed in an inhomogeneous solution of smaller non-adsorbing polymers will move towards regions of lower polymer concentration, in order to reduce the free energy of the interface between the surface of the particle and the solution.
