Reservoir rock wettability has been linked to the adsorption of crude fractions on rock, with much attention often paid bulk mineralogy rather than contacting minerals. Crude oil is contacted by different minerals that contribute wettability. The clay mineral effect alterations examined using surface charge. Also, pH change due well operations was investigated. Clay charge zeta potential computed from particle electrophoretic mobility. considered in this study include kaolinite,...

The reservoir rock is made up of different minerals and its surface chemistry influenced by the environment. Well operations implemented during life a field induce changes in environment (pH) that affect minerals, resulting change their chemistry. These result wettability alterations, which have significant effect on overall production. Thus, this research provides insight into behavior calcite, feldspar, barite, dolomite, quartz, sand varying pH environments to ascertain mineral charge....

Water- and solvent-based ex situ extraction processes have been employed to extract bitumen from mineable oil sands. On the other hand, is recovered in deeper deposits most efficiently by injecting steam reduce viscosity increasing production flow surface. However, water-based process with or without solvent (including injection) not sustainable due various challenges including water requirement treatment, high energy consumption, related environmental pollution problems emanating volatility...

Asphaltene adsorption and deposition onto rock surfaces are predominantly the cause of wettability permeability alterations which result in well productivity losses. These can be induced by rock–fluid interactions affected operations such as acidizing, stimulation, gas injections, so forth. Iron minerals found abundantly sandstone reservoir formations pose a problem precipitation polar crude components. This is due to interactions, dependent on pH; thus, this research work studied surface...

Carbonate reservoirs are made up of predominantly calcite and dolomite minerals hold significant hydrocarbon reserves globally. However, the production from carbonate is limited due to their wettability, which controls fluid distribution. To develop efficient strategies for producing these formations, it necessary understand underlining mechanisms rock wettability. We believe that understanding native state mineral in reservoir environment how oilfield operations affect wetting critical...

Concrete is a major construction material, that largely made up of cement; however, its high cost and ecological unsustainability has been source concern over the years in industry. In recent years, innovative cementitious materials can be used as an alternative for ordinary Portland cement (OPC) with improved performance emission, are locally to reduce CO2 emission into atmosphere during production concrete production. Therefore, geopolymer environmentally beneficial binder material was...

Scale formation and deposition in the subsurface surface facilities have been recognized as a major cause of flow assurance issues oil gas industry. Sulfate-based scales such sulfates calcium (anhydrite gypsum) barium (barite) are some commonly encountered during hydrocarbon production operations. Oilfield well-known problem, which occurs mainly due to mixing incompatible brines.

Enhanced oil recovery (EOR) is the process of residual production in tertiary stage. It requires injection external energy sources such as gases, chemicals, and thermal reservoirs. Chemical enhanced (CEOR) can boost significantly by improving microscopic displacement trapped pore spaces reservoir rock. Each type chemical flooding depends on different mechanisms to enhance recovery. Surfactant aims reduce interfacial tension, alter wettability rock more water wet, promote porous media. The...

For many years, formation damage caused by asphaltene precipitation and deposition has been an issue. The most detrimental impacts are changes to wettability, permeability, flow area, which ultimately reduce production. To this end, several remediation methods, with considerable economic ramifications, have adopted, including mechanical removal of the deposits or injection chemicals dissolve deposits. Due its advantages over procedures, chemical used extensively in industry remove deposits;...

The reduction of carbon footprints is one the steps being taken as world looks for a solution to difficulties caused by climate change.
