Abstract The research of the current study is primarily focused on evaluating reservoir performance by utilizing waterflood technique, based a case at Lanea oil field located in Chad; various mechanisms along with approaches were used considering best suitable pattern for waterflooding. All simulation work was compared against base case, where there no involvement water injection. Moreover, sig...

This paper presents a numerical study to investigate the feasibility of transporting mist through the internal cooling channel in high-pressure turbine vanes for film cooling over the vane's surface. The idea of using mist film cooling to enhance conventional air cooling has been proven to be a feasible technique in the laboratory conditions and by computational simulations. However, there is a...

Designing and manufacturing the multiple jets simulator and experimental investigation of the multiple jets in crossflow at low velocity ratios have been studied Together with design and build a low-speed wind tunnel. A specific rake is used to determine the flow field pressure and changes in static pressure measured by pressure taps in the near field of the jets. There are generally three regi...

We have investigated the effect of wettability of carbonate rocks on the morphologies of remaining oil after sequential oil and brine injection in a capillary-dominated flow regime at elevated pressure. The wettability of Ketton limestone was altered in situ using an oil phase doped with fatty acid which produced mixed-wet conditions (the contact angle where oil contacted the solid surface, mea...

Start-up and dynamic responses to changes in load are reported for a dry feed, autohumidified polymer electrolyte membrane fuel cell PEMFC . The fuel cell current can be ignited by water injection; criteria are derived for the required water injection as functions of fuel cell size, temperature, and reactant feed rates. Steady-state multiplicity is observed where the fuel cell current can be ei...

The impermeability of concrete the exterior wall underground tunnel in water-rich stratum is a key concern engineers. Taking Aixihu highway Nanchang city as an example, side tested, through multiple tests, such embedded steel pipe, water injection, and field observation. results show that, under action 2mpa pressure, no flow permeates from tunnel, indicating that impermeable performance this se...

A hydrogel was prepared by crosslinking aqueous solutions of sulfonated polyacrylamide/chromium triacetate for use in water shut off operations. Gel swelling and the effects of salinity, injection time and flow rate on residual resistance factor (Frr) were investigated. In the presence of electrolytes, gel swelling decreased by about 80%. Results showed that oil permeability increased as inject...

Coherent tunable terahertz (THz) waves were successfully generated using an injection-seeded THz-wave parametric generator (TPG) based on laser light scattering from the A1-symmetry polariton mode of MgO:LiNbO3 crystals. THz-wave spectrum narrowing to the Fourier transform limit was achieved by injection seeding the idler wave (near-infrared Stokes). This resulted in a THz-wave output approxima...

The main challenge in extracting geothermal energy is to overcome issues relating reservoirs such as the formation damage and fracturing. objective of this study develop an integrated framework that considers geochemical geomechanics aspects a reservoir characterizes various damages impairment porosity permeability, hydraulic fracturing, lowering breakdown pressure, associated heat recovery.
