... a significant impact of reaction kinetics on the rate of wettability alteration compared to assuming instantaneous equilibrium. To adequately represent field-scale response from the laboratory scale, one needs to ensure that comparable Damköhler numbers are used. Some laboratory corefloods for LSWF may...

.... The simulation results of the developed numerical model have been validated with experimental results. Various injection velocities and the second Damkohler numbers have been examined to investigate their impacts on the CO 2 bubble generation, evolving porosity, and rock surface area. We categorized the evolving...

... corresponding to the least acid consumption through linear corefloods of carbonates. Fredd and Fogler ( 1999 ) used a wide range of fluid/mineral systems to reveal a common dependence for flow and reaction on the Damköhler number at which the required pore volume (PV) to breakthrough is the least. The Damköhler...

..., and 3.8 were used. The optimum conditions of injection rate and pH were determined using coreflood experiments. Damköhler number was determined using the wormhole length and diameter from the CT scan 3D and 2D images. GLDA was compared with chelates that are used in the oil industry such as EDTA and HEDTA...

... = ( π / 20 ) 3 / 2 r max 3 k L ¯ . The optimal Damkohler number is fixed for a given formation and depends strongly on the largest pore size naturally occurring. If treating conditions (acid reaction rate and acid flux) can be set in the field to yield the optimal...

... processes such as the transport of reactants to the surface, the reversible surface reactions, and the transport of products away from the surface. When these transport and reaction processes are taken into account, a common dependence of the dissolution phenomenon on the Damköhler number is observed...

... provide negligible resistance to flow and carry essentially all the injected fluid. Previous studies have shown that the phenomenon of wormhole formation is governed by the Damköhler number for flow and reaction. 12 The Damköhler number, N Da , is defined as the ratio of the net rate...
