.... Numerical simulation results are obtained by solving coupled macroscopic equations using the finite element method for a quarter five-spot source-sink geometry. Based on the numerical solutions, normalized concentration profiles of the displacing fluid as well as plots of resident and effluent...

... of stirring, the CO 2 dissolution takes a long time, however, the use of stirring expedites the dissolution process. Thermodynamically, we have an instantaneous equilibrium at the gas–liquid interface and the equilibrium concentration at the gas–liquid interface is the maximum concentration of dissolved gas...

... Abstract In the completions of deep-water wells with the presence of gas, it may be necessary to use gas hydrate inhibitors, in these cases the design of the completion fluid usually focuses on determining the concentration of hydrate inhibitor and meeting the criteria of maximum pressure...

... Abstract The behavior of two Castor oil based muds (OBM) prepared with additives marketed in Colombia is observed, the concentrations of the additives are the same for both fluids with the difference that one has as rheological modifier a polar activator and the other uses lime. These ones...

... Abstract Well deliverability is directly related to the hydraulic fracture conductivity of the created fracture networks. There are several influencing factors on fracture conductivity, including fracture surface topography, mechanical properties, and proppant concentration. Fracture surface...
